    1.Executive Summary

    This deliverable reports on the implementation, execution and evaluation of the

    EXPERIMEDIA experiment for interactive camera-based coaching and training (iCaCoT), which

    focuses on interactive video navigation for camera-based coaching and training for visitors andsports enthusiasts in Schladming. The goal of this experiment is to showcase the unique

    properties of tiled adaptive streaming, a technology that was developed in the EU FP7 project

    FascinatE and that allows users to navigate freely through high resolution video panoramas,

    while the application reduces bandwidth requirements by only sending that part of the video a

    user is interested in.

    During this experiment, we have developed the iCaCoT application and have run two

    experimental periods at the EXPERIMEDIA Schladming venue to test the feasibility of the

    concept of interactive camera-based coaching and training. Through the experiment, the existing

    EXPERIMEDIA technical components, notably the Experiment Content Component, havebeen used and tested. The experiment has had impact by raising the attractiveness of Schladming

    as a venue for smart sport tourism, by providing valuable input to MPEG DASH

    standardization, by developing technology for large-scale tests by the BBC beyond Schladming

    and EXPERIMEDIA, and by enhancing the potential for exploitation of tiled streaming

    technology.

    2.Introduction

    The present report documents the preparation, experimental setup and analysis of the

    experiments conducted with the interactive Camera-based Coaching and Training (iCaCoT)

    concept described in EXPERIMEDIA deliverable D4.11.1, which makes use of the tiledadaptive streaming technology developed at TNO1. This technology, created within the context

    of the FascinatE project2, allows users to interact with and navigate within a recorded video

    using pan-tilt-zoom (PTZ) commands.

    Figure 1: Interactive Camera-based Coaching and Training using tiled streaming for video navigation.

    To apply the TNO tiled streaming technology within the context of the EXPERIMEDIA

    project, i.e. as a tool for training and coaching and as a novel way for Schladming visitors to

    record themselves coming down the mountain and sharing their experiences with friends and

    family, we have built a number of additional components/features in the following areas:

    support for live streaming

    additional app functionalities

    integration with existing EXPERIMEDIA components;

    a monitoring platform that oversees the overall functioning of the iCaCoT components.

    In addition, a questionnaire has been developed, with the aim of capturing user feedback in a

    direct manner. A detailed description of the (new) architectural components, the integration with

    the EXPERIMEDIA baseline components and the questionnaire approach is reported in

    Section 3.

    In the following sections we (i) provide a background of TNO's tiled streaming technology and

    its applicability as a tool for coaching and training for skiers, and (ii) summarize the objectives of

    the experiments.

    2.1. Background

    Figure 2: Impression of interaction with video on a tablet device.

    Our hypothesis is that the concept of tiled adaptive streaming is particularly well suited to

    training and coaching applications, since it offers a trainer using a smartphone or tablet, the

    ability to zoom in on his student coming down the mountain, focusing on specific areas, both

    temporally as well as spatially. For example, as shown inFigure 2,a football trainer could pauseand zoom in to the video, to highlight a specific situation. This is especially useful in snow

    activities, where the exact line followed by the trainee is not known a-priori and can therefore

    only be captured using a wide-angle lens located relatively far from the action. By pausing the

    video at key moments, trainer and trainee can focus on and discuss details of the performance.

    By placing multiple high resolution cameras around strategic positions, it is even possible for a

    trainer to view a moment from different angles.

    The iCaCoT experiments have been performed in the Schladming venue, a well-known ski

    location in Austria, which has hosted the Alpine Skiing World Championship in February 2013.

    In addition, Schladming was ideal for the fact that it is also a renowned ski training area, and thevenue partner is involved in supporting and facilitating such ski trainings. Hence, performing

    experiments in Schladming has given us the required level of scale for this experiment, i.e. to test

    how actual users use the concept of tiled adaptive streaming in a live and real-world

    environment.

    2.2. Objectives

    The experiments have been conducted with the aim of fulfilling the following three main

    objectives, as mentioned in D4.11.1:

    1)

    Capture the user experience when interacting with the tiled streaming application:

    8/44

    Copyright TNO and other members of the EXPERIMEDIA consortium 2013-14 8

    In particular, our focus has been on evaluating the user experience from a Quality of

    Service (QoS) and a Quality of Experience (QoE) perspective, to allow for further

    improvement of both the application and the underlying streaming technology.

    2) Test the feasibility of tiled adaptive streaming as a tool for training and coaching activities:

    Here the focus has been on investigating how trainers used the system, and whether the

    tiled streaming concept is helpful in their instruction activities.

    3) Leveraging information obtained through large-scale user tests to improve tiled adaptive streaming

    bandwidth efficiency:

    In order to reach this objective, we have collected a large amount of data concerning the

    usage of the iCaCoT app and the associated video streams during all the experiments.

    2.3.

    Experiment scenarios

    For the experiments, two scenarios have been discussed with the Schladming venue.

    One scenario focusses on young ski athletes, training for their participation in large and nationalevents. The Schladming venue partner, Schladming20303had arranged for coaches / trainers to

    participate in the experiment, along with their students, to use the app in their training approach

    and to provide direct feedback to students. A second scenario focusses on visitors of a

    Schladming fun park, interested in a mix of training and entertainment. Important features here

    are the possibilities of social sharing and ease-of-use.

    While both scenarios have been pursued during the preparation of the experiments, only the

    training/coaching scenario has been fully tested during both experiment runs. This is because

    when discussing the fun park / tourist scenario with visitors on the skiing slopes, they referred to

    the popularity of GoPro helmet cameras, which provide the ability to film up close, resulting inbetter quality footage than a statically mounted camera on the edge of the slope. In addition,

    detailed analysis of skiing performance, which is the focus of the iCaCoT app, is of less interest

    to recreational skiers.

    3.Experiment Preparation

    This section outlines the preparation necessary to perform the experiments.

    3.1.

    Participants and VenueThe experiment has taken place in the Schladming region. Over a period of 2 months, we have

    performed two experiment rounds. The first took place in week 8 (February 17-21) and the

    second in week 13 (March 25-29) of 2014. During each round, 2-3 days of experiments took

    place, with the remainder of the time spent on system set-up, testing and break-down. In

    particular, the Reiteralm area (see a map in the figure below) was chosen as setup for the

    experiments, because it is well-suited for (semi-)pro coaching and training purposes.

    Figure 3: Reiteralm locations for the iCaCoT experiments.

    System set-up involved various challenging tasks, such as installing and connecting cameras over

    distances of hundreds of metres on the skiing slope, and installing cables via underground

    bunkers.Figure 4 andFigure 5 give some impressions of the system set-up effort.

    Persons who used the iCaCoT application during the two experimental periods are

    providing the majority of QoS and QoE data. In particular:

    o Trainers (2-5 people): persons that used the application in both the first and the

    second experiment run and whose feedback has been used for adaptation of the

    experiment and application in the second experiment run.o Students (1-10 people): persons that participated in the experiments.

    Local stakeholders

    Local stakeholders in Schladming, primarily representatives of the companies operating

    the cable cars who are in charge of the ski areas and local installations. They have

    supported the installation and maintenance of the camera setups.

    Experimenters

    Experimenters have overviewed the execution and analysis of the experiments.

    3.2.

    App FunctionalitiesTo fit the purpose of the experiment, a number of functionalities have been added in the

    implementation of the iCaCoT app. These functionalities can be broadly classified into two

    categories:

    GUI functionalities

    o Draw;

    o Bookmark a position in time (due to space limitation on the user interface, a

    maximum of 6 bookmarks can be stored);

    o

    Stepframe, or step forward, i.e. the ability to step through frames when the videoplayback is paused; this function is used by the trainer to show the students his exact

    moves, in order to explain what to improve;

    o Seek, either via a slider or via dedicated buttons (+3, +15, -3, -15 seconds). Inside the

    application, this translates to seeking one or multiple segments. This function serves

    the purpose of finding the next student within the video playback, and is used by the

    ski trainer after he has finished with the previous student and wants to move to give

    feedback to the next student.

    Measurement/logging functionalities

    o Network monitor, i.e. bandwidth and data usage;

    o Usage monitor, where a large set of metrics is captured, as described in

    EXPERIMEDIA document D4.11.1 (e.g. navigation commands, bandwidth usage,

    etc.);

    o Debugging info logging, which the app sends to the TNO monitoring framework.

    In addition, for the second run of experiments the following functionalities have been added:

    GUI functionalities

    o Enhanced draw functionality (line-based, arrow-based and dot-based drawing, plus

    the ability to choose different colours);

    o More control over seeking functionality to make it easier to find students;

    o Slow motion playback functionality (plays the video at 1/4 of the original speed).

    3.3.

    Support for live streaming

    In order to process and render a video feed in real time, the following chain of components has

    been developed:

    Ingestion node, which captures the raw video data and encodes it using Motion JPEG

    codec;

    Processing node, which takes the input encoded in Motion JPEG received from the

    Ingestion node and produces the final watchable video files; this step includes the tiling,

    encoding (in H.264/AVC) and multiplexing (MPEG-TS container) of the content;

    Segmenter, which produces the temporal segmentation of the content.

    The output of the Segmenteris then distributed to the different instances of the iCaCoT app via awebserver.

    Both a high-level and low-level overview of the architecture used in the iCaCoT experiments are

    shown inFigure 10 andFigure 11 below:

    3.4.

    Integration with EXPERIMEDIA Baseline Components

    The iCaCoT app makes use of existing EXPERIMEDIA Baseline components, namely the

    Experiment Content Component (ECC), the Audiovisual Content Component (AVCC) and the

    Social Content Component (SCC) components.

    3.4.1. Integration with ECC

    Within both experiment runs the iCaCoT app had to be integrated with the ECC component, in

    order to log the measurement data captured by the app. The ECC is provided with APIs that can

    be used by ECC clients in order to communicate about experiments and measurements while the

    data is exchanged via a RabbitMQ message bus. These client APIs are available for Java,

    Android, C# and C++ clients.

    At the time of the iCaCoT experiments, the ECC did not have support for iOS clients, such as

    the one built to collect measurement data from the iCaCoT app. Therefore, in order for the

    iCaCoT app to use the functionalities offered by the ECC, the intermediary ECC-Proxydeveloped by the National Technical University of Athens (NTUA) was used. The ECC Proxy

    resides on a separate machine, where (in our architecture) also the ECC component is located

    (seeFigure 11). The ECC Proxy has been implemented as a Java ECC Client which on one side

    communicates with the ECC via the available APIs of the ECC while on the other side provides

    an HTTP Servlet which can be used by the iOS clients to communicate their experiment data via

    HTTP POST messages. SeeFigure 12.The ECC Proxy stores the experiment data from the iOS

    clients locally in a database and provides the ECC with the data from this database.

    Figure 12: Integration of iCaCoT with ECC.

    After the experiments were concluded, the measurement data collected by the ECC can be

    accessed all at once via two CSV files (one with the metadata and the other containing the actual

    measurement data).

    3.4.2.

    Integration with AVCC and SCCFor the second experiment run, the iCaCoT app has been also integrated with the AVCC/SCC

    components, to make use of the Facebook sharing functionality. To realize this, the backend of

    the iCaCoT domain had to be interfaced with the AVCC component, in order to upload the

    video to be shared. In turn, the AVCC component interfaces with the SCC component, which

    shares the videos uploaded via the AVCC on an ad-hoc iCaCoT Facebook page (Figure 13).

    Figure 13: Integration of iCaCoT with AVCC/SCC.

    The AVCC component is accessible as a webserver and offers the following interface:

    Parameter Description Occurrence

    title A string representing the title of the video file to share on Facebook. M

    description A string representing the description of the video file to share onFacebook.

    M

    category A string representing the category of the video file to share onFacebook.

    O

    multiQuality A Boolean representing whether the video file has transcoding profile'flash'

    C

    html5Mp4U A Boolean representing whether the video file has transcoding profile'html5-mp4'

    C

    html5WebM A Boolean representing whether the video file has transcoding profile'html5-webm'

    C

    html5OggM A Boolean representing whether the video file has transcoding profile'html5-ogg'

    C

    html5Mp3audio A Boolean representing whether the video file has transcoding profile'Mp3 audio'

    C

    userName A string representing the title of the video file to share on Facebook. M

    path A string representing the url of the video file to share on Facebook. O

    where "M" denotes a mandatory parameter, "O" an optional parameter and "C" a conditional

    parameter, and at least one conditional parameter shall be present (i.e. and at least one

    transcoding profile shall be selected).

    For the iCaCoT experiment, we have used the mandatory parameters, the transcoding profile

    'html5Mp4U' and the optional parameter 'path'.

    Every time a new video is available for sharing on Facebook, a process running in the iCaCoTbackend sends a POST message to the AVCC webserver endpoint with the above mentioned

    parameters as part of the POST parameters. Upon receipt of the POST message, the AVCC

    webserver responds with a message regarding the status of the request.

    3.5. Questionnaire approach

    In order to obtain user feedback in a more direct way, TNO has developed a number of

    questionnaires meant to be presented to the trainers after their first and second experiment as

    well as to the visitors of the fun park. Only the trainers have used the questionnaires to provide

    feedback on application and experiment.

    3.5.1. Purpose of the questionnaires and general strategy

    Using questionnaires to assess the trainers impressions of the iCaCoT application will directly

    contribute towards Objective 01 and Objective 02 of the experiment. In addition, combining the

    information directly received from the user with the measurement data collected by the iCaCoT

    app will enhance the fulfilment of Objective 03 as well.

    To be effective, a questionnaire should manage to get the desired information without taking too

    much of the participants time. For this reason, the questionnaire has been designed according to

    the following principles:

    Quick and simple assessment;

    Comprehensive impression of the user experience.

    3.5.2. Questions format

    In order to satisfy principle 1, most of the questions have been formulated in the form of

    multiple choices. To satisfy principle 2, the questions have been divided into the followingcategories:

    User satisfaction: measures users quality of experience by asking him/her direct questions

    (e.g. whether his/her experience was good or bad)

    GUI usability: measures whether the user can interact fluently with the app. This includes

    two aspects:

    o Ease of learning (e.g. can the user intuitively learn how to use the app)

    o Ease of interaction, which measures whether the apps features have been

    implemented in the correct way (e.g. seek forward being implemented as a cursor likein YouTube)

    Functional usability: weather the apps features work as they should (e.g. no major hiccups

    within apps usage)

    Application value: measures whether the user perceives that the app is useful for him/her

    Questionnaire implementation

    For the purpose of the first experiment, a questionnaire with a total of 26 questions (of which 23

    were multiple choice questions) has been developed. For the purpose of the second experiment,

    two additional questionnaires where developed:

    one directed to the trainers, with 22 questions;

    the other directed to the visitors of the fun park, with 19 questions.

    The full list of questions presented in each questionnaire is available in7.4.Appendix A.

    The questionnaire was presented to the trainers in the form of a separate app launchable from

    the iPads. This app has been created by means of the QuickTapSurvey tool4, which allowed us to

    deploy the questionnaire on multiple devices as well as collect and aggregate all responses on a

    central server accessible via the web. It is important to notice that the questionnaire is completely

    anonymous and that it does not use any participant's information. A screenshot of one of thequestions presented to the trainers is showed inFigure 14.

    Figure 14: Screenshot from the questionnaire tool.

    3.6. Monitoring platform

    TNO has developed a light weight monitoring platform which receives real-time status

    information from the components within the experiment platform like the iCaCoT app and

    AvccConnector. This way, our experimenters were able to monitor in real time the situation

    while trainers were using the app.

    The different components in the iCaCoT platform can connect to the log server of the TNO

    monitoring platform either via a web socket connection or a HTTP post (Figure 15). Finally, the

    TNO monitoring platform includes a number of scripts to start up and coordinate all the

    processes which are needed to enable the experiment to take place.

    3.7. Ethics and Privacy

    As described in D4.11.1, with the iCaCoT experiment we aimed to adhere to the following

    principles with respect to ethics and privacy:

    Transparency through notification screen to explain nature and purpose of experiment;

    Obtain explicit informed consent through 'I agree' button in the application;

    Observational research in situations where those observed would expect to be observed;

    Collected data will only be used for purposes of experiment and shared with participants.

    During both experiment runs, these principles have been upheld in the following ways:

    At the experiment venue, a notification sign was shown to inform all participants and

    people on the slopes about the video recordings;

    Informed consent by the experiment participants (trainers / coaches) was explicitly

    obtained through signed consent forms. These forms also explained the nature and

    purpose of the experiment;

    Observational research has been conducted through video recordings;

    The collected data is only used for the purpose of the experiments. Some specific

    recordings have been made for demonstration purposes.

    Note that the experiment involved minors, i.e. most of the students. Consent was asked via the

    trainers who also monitored the process. The students did not need to download the application

    and were not involved in any data measurements.

    In relation to the formal requirements as listed in D4.11.1:

    4.Experiment Setup

    This section documents the setup that was necessary in order to conduct the iCaCoT

    experiments.

    4.1. General setup

    Both experiments took place in the Reiteralm location in Schladming, Austria (Figure 3, in

    Section 3). During both experiment runs, a team of TNO experimenters was present in the

    venue to setup the infrastructure, monitor the experiments and assist the experiment

    participants.

    A high level view of the necessary infrastructure is reported inFigure 17.

    Figure 17: Infrastructure to support the experiments.

    Furthermore, two bunkers, located on the slopes, were used for equipment storage and to host

    switches for the cables.

    4.2.

    Details from the first experiment run

    The first experiment period took place in week 8 of 2014. Together with the venue partner, the

    team spent the first 2 days setting up the necessary infrastructure to support the architecture in

    Figure 17. Furthermore, a smoke test was performed to check that the complete ecosystem

    worked. Finally, the selection of the participants was carried out.

    GoPro Hero 3+ cameras6where installed on the Reiteralm slope, with 520m UTP and HD-SDI

    cables running along the slopes all the way to the wooden control room (Figure 18). During the

    experiment, one GoPro was changed for a JVC Handycam which yielded a better image quality

    due to better optics.

    4.3.

    Details from the second experiment run

    The second experimental run was executed in week 13 of 2014.Based on the experience from the

    first run, the team spent only half a day for experimental setup. The experimental setup was

    similar to the first run, except that this time one GoPro was replaced by a Blackmagic Design 4K

    camera7.

    5.Experiment execution

    Each experiment period was accompanied by a "day-to-day script", which aided the

    experimenters to ensure an efficient and correct execution of the experiments. Relevant details

    of the execution for both experiments are reported in the following paragraphs.

    5.1.

    First experiment run

    After having introduced the experiment to the participants in the ski school on the morning of

    the third day, the first experiment was performed in the afternoon of the same day. During this

    day, two trainers took part in the experiment, with a group of 7-8 students in total. On the next

    day, another experiment was performed with two trainers, each having a group of 7-8 students

    (Figure 19,3 examples).

    The second experiment run was performed within three days. In addition to the ski trainers, this

    time also a snowboarder trainer with his student participated in the morning of the first day.

    Other four sessions have been performed in the subsequent days, with the ski trainers and

    groups of students of up to 10 individuals until Saturday morning.

    6.Analysis of experiment results

    As discussed in EXPERIMEDIA deliverable D4.11.1, our aim for the iCaCoT experiments is to

    evaluate the user experience from a Quality of Service (QoS) and a Quality of Experience (QoE)

    perspective, to allow for further improvement of both the application and the underlyingstreaming technology. To do so, we have captured the following data throughout the

    experiments:

    QoE

    o Direct measurements of user satisfaction through questionnaires;

    o Application feature usage;

    o User's navigation information within the App.

    QoS

    o Bandwidth of received streams;

    o Interruptions in stream reception;

    o Switching delay between resolution layers;

    o Networking conditions.

    In the section that follows, we report a detailed analysis of the above mentioned data, for both

    experiment runs.

    6.1. QoE analysis

    6.1.1.

    Questionnaire results

    In general, questionnaire results show that the participants had a very good experience with the

    iCaCot app, both in the first and second run (75% of the respondents in the first run rate their

    experience as good or very good, and in the second run this is 100% of the respondents)

    and all of them would recommend the app to others (100% of the respondents in both

    experimental runs).

    Furthermore, the questionnaire results show that the iCaCoT app performs well against the

    expectations of the participants, and this feeling did even increase in the second run. While in the

    first experimental run the iCaCoT app exceeded the expectations of 50% of the participants, in

    the second run it exceeded the expectations of all participants, as shown inFigure 21.

    Figure 21: iCaCoT perceived performance versus participants' expectations.

    Moreover, the questionnaire results show the increase in perceived video quality between the 1st

    and 2nd experiment run. As shown in Figure 22,all participants perceived the video quality at

    least as not good or bad in the 2nd run, whereas the video quality was perceived bad by some

    users in the 1st run.

    In general, the participants were less satisfied with the video quality, especially during the first

    run. This can be explained by the type of camera that was used (GoPros). When 4K cameras

    where used in the second run, the participants did notice an improvement of the video quality

    and considered it overall acceptable.

    Furthermore, the participants were relatively satisfied with the set of functionalities offered by

    the iCaCoT app (especially in the second run where enhanced drawing functionalities and the

    slow motion playback functionality was added). As potential for improvement, they

    recommend to focus on more graphical aspects, such as providing the user with the ability to

    easily find a student in the video playback and show two students in parallel for comparison.

    Finally, all the participants from both runs considered the iCaCoT app very useful as a means for

    training and coaching, and consider it beneficial for both students and ski trainers.

    Figure 25: iCaCoT app feature usage during the 2nd experiment run.

    As we can observe from bothFigure 24 andFigure 25,the most popular functions in both runs

    are "step forwards" and "seek the next segment". As described in section3.2,the first function is

    used by the trainer to show the students his exact moves, in order to explain what to improve.

    The second function serves the purpose of finding the next student within the video playback,

    and is used by the ski trainer after he has finished with the previous student and wants to move

    to give feedback to the next student.

    Furthermore, we can observe that the bookmark function was almost never used. This is due to

    the fact that the trainers where usually not watching the students from the app in real time, but

    rather playing it back every time a new student came down the slope.

    Similarly, camera changes did not appear often. This might be due to the fact that the cameras

    were well positioned to get a good overview of the slope (and therefore switching between them

    was not needed), or that the participants did not know or get used to switch between cameras.

    As remarked by one of the trainers, "one of the most useful functions to illustrate the athletes

    current position along the course of motion. It gives you a hint of the origin of a potential

    mistake in an athletes motion sequence.The strong preference for such trick play functionality

    has influenced the additional feature designs for the 2nd experimental run.

    6.1.3. User navigation

    We have also captured the user navigation within the iCaCoT app, in order to assess areas of

    particular interests.Figure 26below shows a heatmap of the most watched areas within a video

    for the session with the snowboarder (on the first day of the second run):

    Figure 26: Heatmap of the most watched areas

    This information can be used in multiple ways. For example, the TNO iCaCoT tiling module cantake this information into account to optimize the tiling for this video. Furthermore, information

    about areas of interests such as this can aid the choice for the positioning of the cameras during

    the event.

    6.2. QoS analysis

    In this section, we analyse the results obtained from the measurement data. Specifically, we

    looked at the bit rate, data usage and dropped frames.Figure 27 shows the measured data over

    one session of about 11 minutes. As we can observe, the iCaCoT app is very efficient in the data

    transmitted, and only 8 frames have been skipped in total, which can explain why the iCaCoT

    app exceeded the expectations of the participants.

    Copyright TNO and other members of the EXPERIMEDIA consortium 2013-14 32

    Furthermore, we see a correlation between the instant when a frame was dropped and the usage

    of the app from the participant: usually a frame drop happens when a video is resumed from

    pause. We can also observe that the highest and most frequent peaks in bandwidth usage happen

    around frequent switching between pause and resume. This is valuable information that can aid

    the further improvement of the iCaCoT app.

    Figure 28: Measurement data from second experimental run.

    6.3. Feedback from venue partner

    In addition to the QoS and QoE analysis results as presented in the previous two sections, the

    venue partner has provided post-experiment feedback. In their view, the outcomes of the

    experiments have definitely shown that with the iCaCoT trainings application, athletes and

    students have a number of several advantages. Generally spoken, a video feedback between the

    training runs allows an athlete an immediate spot view of his or her movement and makes the

    coaches advices more understandable. Not only professional athletes benefit from such

    applications but also semi-professional ski and snowboard athletes as well as talented young

    skiers and boarders. The two experiments have already shown that not only the athletes benefitfrom the application but also the quality of the training. The following paragraphs summarize the

    pros and cons of the application and give some suggestions for the further development of

    iCaCoT from the coaches point of view.

    6.3.1. User friendliness of the tested application

    After a short time of testing the application, the coaches got used to it and were able to focus on

    what they wanted to explain their athletes. Most of them mentioned during interacting with

    iCacoT that the timeline as well as the application menu should be located at the bottom. The

    reason for this is, that the view (of the athlete and trainer) is interfered by the acting hand.Another problem that has already been discussed and partly solved is the searching function via

  • 8/11/2019 D4.11.3 ICaCoT Experiment Results and Evaluation v1.0

    34/44

    EXPERIMEDIA Dissemination level: PU

    Copyright TNO and other members of the EXPERIMEDIA consortium 2013-14 34

    the time line. First of all, the bookmark function makes sense for a small training-group (3-6

    athletes) that stays frequently together during the runs and analysis. Searching an athlete in the

    timeline has proven to be time intensive.

    6.3.2. Features and Functions of the tested application

    Frame to frame function

    This is one of the most useful functions in order to illustrate the athletes currentposition along

    the course of motion. Each frame may give you a hint of the origin of a potential mistake in an

    athletes motion sequence.

    Slow motion function

    This function is necessary to explain the results of mistakes in a clear manner. Due to the

    decelerated speed of the course of motion, the athlete is able to see and understand the

    outcomes of his performance. In the two experiments at the Reiteralm location, a 1:4 slow-motion was used. Some coaches suggested implementing at least 3 more possibilities of the slow-

    motion function namely 1:2, 1:6 and 1:8 standards. Some of the coaches would even favour a

    backwards slow-motion function, though difficult to implement.

    Fast Forward, Fast Backward (3 seconds, 15 seconds) and live button

    This feature was often used as a searching function in order to find a certain athlete. Even

    though it took some time to capture the right student, it fulfilled the intended functionality. The

    Live button has frequently been used as a kind of searching function and was a good indication

    for the coaches time-orientation.

    Drawing functions

    Generally the offered functions (freedom drawing, arrows, straight lines, dots) satisfied the

    expectations and the required visual assistance. However, implementing moving visualisation

    tools like moving arrows and automatically estimated angles of two crossing lines would set new

    standards of analysis-tools.

    Additional desired features and functions

    Thinking about a permanent training track which combines the interactive camera basedcoaching and training application and electronic timing, an interface should be found. A

    combination of visual feedback and integrated electronic time-comparisons (athlete to athlete or

    individual time to individual time) would create a product which does not exist yet (high

    attractiveness). Another desired function is a face to face possibility, where either two different

    athletes or two different runs of one athlete can be compared at one sight.

    Storage & Export function

    Exporting the video-stream, sharing it through social media or store it in an individual cloud

    could be considered as a basic function. The store and export function worked just from thecapture system but unfortunately not directly from the application. The export function should

  • 8/11/2019 D4.11.3 ICaCoT Experiment Results and Evaluation v1.0

    35/44

    EXPERIMEDIA Dissemination level: PU

    Copyright TNO and other members of the EXPERIMEDIA consortium 2013-14 35

    give training groups the possibility to handle the video analysis more flexible. In addition it could

    also be helpful to provide access to the video stream if coaches are not able to accompany the

    training (personal coaches, individual training without coaches, etc.).

    6.3.3. Quality of the video stream and requirements for professional training

    During the first experiment, the quality of the streamed video (recorded with GoPros HD) has

    been proved as insufficient. This resulted likely from the GoPro lenses with very wide angles.

    However, changing the type of camera did not lead to a sufficient solution. In the second

    experimental run, a 4K camera was used which provided a useful quality and could be seen as a

    minimum standard for a further development of a fixed installed service application. In this case,

    coaches would accept some quality resolution-distortion, if the video stream is guaranteed in 4K

    quality. Also with a 4K camera, a really high resolution is hardly possible to generate. This

    circumstance could be solved, if individual cameras of the users were connectable with the

    iCaCoT program. In this case two zooming functions were available, one offered directly by the

    individual camera (manual zooming) and one offered by the application.

    7.Conclusions

    7.1. General

    In general, we find that the iCaCoT application could reduce the amount of training runs in

    order to achieve a certain training objective. Students get additional information and an externalview of their performance and it is easier to determine the origins of faults. A trainer can focus

    his or her attention on corrections and can report on direct visible progress of the athletes. While

    a trainer might not need video feedback after every single run, one could use it as additional

    support for coaching.

    A significant advantage of the tiled streaming-based training and coaching application is that is

    separates the recording aspect from the interactive training aspect. Previously, trainers would

    have focus on recording during training sessions, and would be able to give feedback only after

    analysis of the recorded training sessions. With the iCaCoT application, trainers can focus on the

    training itself andcan give faster feedback.

    When considering the initial objectives of the experiment:

    1) Capture the user experience when interacting with the tiled streaming application:

    Our evaluation of the user experience from a Quality of Service (QoS) and a Quality of

    Experience (QoE) perspective has allowed us to further improve both the iCaCot

    application and the underlying streaming technology.

    2) Test the feasibility of tiled adaptive streaming as a tool for training and coaching activities:

    Our investigation of how trainers used the system showed us that the tiled streaming

    concept is helpful in their instruction activities.

    3) Leveraging information obtained through large-scale user tests to improve tiled adaptive streaming

    bandwidth efficiency:

    Our collection and analysis of a large amount of data concerning the usage of the

    iCaCoT app and the associated video streams during all the experiments has enabled us

    to identify aspects to improve and modify.

    7.2. Feedback on EXPERIMEDIA Baseline Components

    With the iCaCot experiment and application, we have focussed on using the ECC as a metric

    logging system. While the ECC has enabled us to capture large datasets for analysis, weencountered several problems in our usage of the ECC component and proxy. We provide his

    feedback to the core component developers so they can further improve these components.

    Performance issues with the ECC Proxy

    For our experiments different metrics have been defined which relate to both the Quality of

    Service as well as the Quality of Experience of our iCaCoT application. One of these metrics was

    called CurrentVideoArea which relates to the part of a video frame that is currently displayed

    on screen. As this metric is generated for each frame of the video stream, the metric is generated

    25 times per second for each iOS client that is using the iCaCoT application resulting in a lot of

    data that needs to be processed by the ECC Proxy. Due to this high amount of metric data, a lot

    of effort was needed in order to optimize the ECC Proxy to handle this amount of data.

    Stability of the ECC and ECC Proxy

    During our development and experimentation phases we noticed that the ECC and ECC Proxywhere not always as stable as expected. Some times for example, the ECC Proxy was not

    detected by the ECC which results in the fact that no measurements are stored within the ECC

    database. Even though the ECC was started prior to the ECC Proxy. While this issue has been

    mostly resolved thanks to the baseline component developers, the operation during experiments

    is still not as stable as one would like.

    Post reporting with the ECC

    Another problem we encountered during our experiments is the fact that with the current

    version of the ECC, the post reporting functionality is rather limited. For example you are onlyable to export all metric-data and measurement-data in one CSV file, which should then be

    processed manually. With a few million measurements this is not the ideal way to go. Also when

    the unfortunate situation arose where the ECC crashed, we were no longer able to access our

    metric data via the ECC.

    Using the AVCC and SCC through the Social Annotation service

    We have not been able to rigorously test the combined AVCC and SCC functionality during our

    experiments. From our work on integration of the components, our impressions are that an

    operational combination of these components requires in-experiment control and guidance bythe baseline component developers. Therefore, it would be beneficial to create a ready-to-deploy

    version of this combination of components.

    7.3. Dissemination and Exploitation

    Intermediate and final results of the iCaCoT experiment have been disseminated via several

    channels:

    Several Austrian online news sites, including the largest online tabloid site

    A presentation at Immovator Cross Media Caf: Sports and New Media9. Immovator is

    the Dutch SME cluster for ICT and media.

    An abstract for a paper presentation at IBC2014, Europe's largest conference on

    broadcast media. The paper will discuss tiled streaming and will highlight some of the

    iCaCoT results within EXPERIMEDIA.

    7.4.

    Exploitation and follow-up

    The exploitation of tiled streaming technology by TNO aims at licensing the technology to a 3rd

    party. In discussions with interested parties, the scalable live streaming feature has been

    highlighted as a significant advantage of the technology and system, and progress in the area was

    much sought after. With the iCaCoT experiment and the support of EXPERIMEDIA, TNO has

    been able to develop such a live system and application, which greatly support ongoing

    discussions with potential licensing partners.

    In addition to the exploitation of the generic tiled streaming technology, the specific iCaCoTapplication, developed for testing and training, has generated interest from parties in both

    Austria and The Netherlands. Ongoing joint exploration of the exploitation potential by TNO

    and the Schladming venue partners may lead to integration of the system and application at ski

    slopes at the Schladming venue. The venue partner has identified two specific product-market

    combinations of interest:

    Flexible version: Wifi camcorder stream to interact via the iCaCot application. Could

    serve as a low-end product for coaching and training. Target groups include sport

    associations with the main focus on: Alpine skiing, Freestyle Skiing, Ski jumping and

    snowboarding.

    Fixed version: it is clear which infrastructure is needed to run the iCaCot application on a

    potential location. The high-end version would attract a number of teams interested in a

    professional training infrastructure. Target groups include cable-car companies that (may)

    offer permanent training tracks for snow-sports accessible through application-stores

    Direct follow-up of the iCaCoT experiment is pursued by TNO through collaboration with BBC

    R&D towards the Commonwealth Games 2014 in Glasgow. We aim to produce live 4K footage

    and deliver this via tiled streaming to end-users in large-scale trial. This allows to determine the

    impact of live 4K tiled streaming on regular production environment and to measure the effects

    of tiled streaming on bandwidth and latency in a regular content delivery setting. The use of the

    EXPERIMEDIA ECC baseline component in this BBC-TNO trial is being explored.

    A.1. Questionnaire for the first experiment run

    For the first experiment run, a questionnaire directed to the ski trainers was developed. The

    questionnaire requests the trainers to give feedback on the aspects reported below. These aspects

    are classified according to the categories identified in Section3.5.

    Questionnaires for the second experiment run

    For the second experiment run, two questionnaires were developed: one for the trainers and one

    for the fun park visitors.

    A.2.1.

    Adapted questionnaire for the trainersThe questionnaire for the trainers was an adapted version of the first questionnaire. Based on the

    feedback from the first run, we could determine that a number of questions were less relevant

    for the trainers (such as the ones on the enjoyability or friendliness of the app) or for the second

    run (e.g. the ease of learning and interaction, since the trainers were already used to the app).

    Therefore these questions were removed in the new questionnaire. Furthermore, a few new

    questions have been added in order to assess the impact of changes/improvements done to the

    iCaCoT app between the first and second run. These are highlighted in green below.
