Evolution to even higher speeds and lower latency

2006


4G is the short term for fourth-generation wireless, the stage of broadband mobile communications that will supersede the third generation (3G). While neither standards bodies nor carriers have defined or agreed upon what exactly 4G will be, it is expected that very high bit rate, low latency end-to-end IP and high-quality streaming video will be among 4G's distinguishing features.

The International Telecommunication Union (ITU) defines "4G" as network technology with throughput of 100Mbps for wide area/mobile use and 1Gbps for hot spot coverage to be applied in new spectrum bands with 100 MHz channels.

Many experts believe that our main internet experience will be mobile within the next 5 years


The mobile handset evolution: Embracing and embedding feature after feature ”Always with you”

Digital camera

Pocket TVTickets, Keys

By end of 2008, there were 4 billion mobile phone subscriptions. This equates to 61% of the world population: International Telecommunication Union 2009.


Device Trends - Displays

Going forward -Higher resolution -TV/Video out – cable and wireless -Built in laser projectors


Trends in Pedagogy – the evolution of the art of teaching

Pedagogy informed by basic principles of constructivism

Emergent theory connectivism (George Siemens)

Because emergent technology is exciting and newly available, it is easy to become absorbed by the technology itself (Simpson 2008)


Context Sensitive Education & Training

Context sensitive education and training refers to training material which is directly relevant to the training situation that the learner finds themselves in.

Solutions

eXact GEO – Ericsson/Giunti Labs

Mediascapes and QR codes – London Metropolitan University

mDIPSEIL v2 – Plovdiv University

Corvinno Studio & CooSpace mLMS – Corvinno Technology Transfer Centre


eXact GEO

Ericsson/Giunti have developed eXact GEO, a customized solution not only able to locate the position of the user but also to provide on demand the list of contents related to the items located around the user. Based on JavaTM 2 Platform, Micro Edition (J2METM) technology that provides a robust, flexible environment for applications running on mobile and other embedded devices such as mobile phones, personal digital assistants (PDAs), TV set-top boxes, and printers.


Mediascapes and QR codes

Delivery and manipulation of its work package products. Mediascapes are a new form of media which combine and layer digital sight, sounds and interactions onto the physical world to create immersive and interactive experiences. Mediascape design is a process of ‘experience design’ which involves interaction design, choice of location, media region design, and an overall specification of the program logic and content production. QR code or SEMAcode which also allow the attaching of information to space. A QR or ‘Quick Response’ code is a two dimension bar code that can be read by all mobile camera phones.The QR code leads to the ‘clickable world’ where any physical object can become an interface to the virtual world (web resource).


mDIPSEIL v2 - Plovdiv

Proprietory systems is usedmDIPSEIL v2 Mobile Learning Management System (MLMS)

– J2ME client application, which must be downloaded and installed to the client’s (student’s) phone;

– Database Engine – such as MySQL, for storing the educational data;

– Web Engine ‐ such as Apache, for managing the data.


Corvinno Studio & CooSpace mLMS

The Corvinno Studio system which is ontology based is used together with Coospace LMS to handle various location and context aware educational situations.


Next Phase - IP Multimedia Subsystem (IMS)

IMS is a horizontal architecture for offering IP Multimedia Applications

IMS is defined in 3GPP/3GPP2 standard, Embraced in TISPAN

IMS supports different access networks, such as:

– WCDMA, GPRS

– CDMA2000

– Wire-line Broadband

– WLAN.

Instant Messaging

Push to Talk

Shared pictures

Shared browsing

Community gaming


Presence and Group Management

IMS allows users, or user’s clients to set their availability (presence) towards other users.

– A user might set themselves up as available for SMS or email but unavailable for Voice and Video Calls.

Groups can be defined for a user’s contacts– For example a user might define a Work, Social, Student

group, etc

Combining Presence with Groups allows students (or tutors) to be very specific about who may and may not contact them while

learning


Today’s Learning Scenario Students arrives on campus (Virtual or real) with own/or provided technology infrastructure (i.e. mobile multimedia device/phone/laptop)Student ID linked to device(s)Student ‘presence’ logged in campus databaseReminders, course and college information can be pushed to student.Network aware of device capabilities. Enables institution to tailor access for student to include courseware, support & social servicesID enables ad hoc groups to form – study buddies, tutorials, informal learning and University social and sporting activities.

Towards a richer learner centric experience


Device & location independent

Lecture hall displays, internet, PC, mobile device


Richer learning experience

Faster connectivity

Media rich content development– Video– Collaboration tools– Group discussion– User created content


Advantages of IMS

IMS provides several services that can be leveraged in mLearning applications and courses

These services include new ways to perform activities on mobile devices (Converged User Sessions)…

…new ways to deliver course material and monitor student participation (IP Based Content Delivery)…

And new ways to help maintain the student’s focus during mLearning Activities (Presence and Group Management)

Emerging Trends

"Emerging trends over the three phases of mobile learning are the enhancement of the desktop, support for learning outside the classroom and the notion of learner mobility with location and context sensitive systems that enable life-long learning transitions across multiple contexts. Ambient and mixed-reality systems and environments may soon be teaching us about themselves. Wide area educational gaming may draw in learners who may be at distance to the school. Also, we saw in the ’CONTSENS’ project that zone-based notifications provides a form of tracking and surveillance that has major ethical implications." (Cook, 2009)


Summary

Is context sensitive training and education the killer application for mobile learning?
