IntegrationPART I: Student MobilityInformation, CEI & Semantic search

Motivation Video

• Questions:

– How could such a system work?

– What should be part of it?

– Would students really use it?

– Doesn’t (google) search already solve this?

– Why not just data visualization?

Student Mobility Information System

• Critique of Manovichs argument to use datamining and visualization to do „media analysis” instead of the traditional “media criticism”:– “*…+ the most significant critique of Manovich’s talk

came from an intelligent questioner at the end… a young man in the front asked, ‘Is visualization even necessary in an age when you have all the data… isn’t the perfect map a 1 to 1 representation?’ ”http://medialogy.net/2008/08/16/new-new-media-lev-manovich-data-visualization-and-borges-maps/

• We don’t need a map to the library of babel, we need a way to navigate it! (cf. Borges)

• Space (2D, 2.5D, 3D)– Position– Size– Distances– Shape

• Time, Color, TextureConnections, Movement

• Sound– Pitch– Duration– Rhythm

Visual Language Dimensions

1. Computation is a medium (communication)

2. Meaning arises on multiple levels (objects,signs, metaphors)

3. Users, not designers, create and communicate meaning

4. Users, not designers, manage coupling

– relating entities for the purpose of action

5. Embodied technologies participate in the world they represent

– artifacts-in-use vs. separation of object and representation

6. Embodied interaction turns action into meaning

– no meaning in the system itself, but in the way it is usedPaul Dourish, Where the Action Is (MIT Press, 2004).

http://mitpress.mit.edu/images/products/books/0262041960-f30.jpg

Embodied Interaction: Design Principles

Embodied Interaction + Data Visualization & Exploration

1. Data visualizations / exploration interfaces act as media2. Meaning in such systems arises on multiple levels

(objects, signs, metaphors)3. Designers can not enforce a user’s context4. The users and not the system designers decide how to

interpret and use the system5. The data has to be situated in a context, an embodied

data exploration interface participates in the world it represents

6. Embodied data exploration turns actions into meaning

> Context Enaction Interface

CEI Sketches Keyword Combination

CEI SketchesInformation Presentation

• Semantic web + search– augment and improve traditional search results

• Two very different kinds of searches:– Navigational search

– Research searchR. Guha, Rob McCool, and Eric Miller, “Semantic Search,” http://www2003.org/cdrom/papers/refereed/p779/ess.html.

• Employ domain knowledge modeled as ontologies to enhance information retrievalD. T. Tran et al., “Expressive resource descriptions for ontology-based information retrieval,” in Proceedings of the 1st International Conference on the Theory of Information Retrieval (ICTIR’07), 18th-20th October, 2007, 55–68.

• Enable systems to construct a personal context

Semantic Search

1. Logo/Name of the project, Help/Info area, Login/Greeting, Dropdown Area for Library/Pinboard (Optional), Dropdown Area for Friends Activity, “Friends“ button

2. Canvas

1. Holds number search/browse-graphs, can hold multiples, Holds Disposal Area (6), that will be used to dipose, delete modes that are not needed, May hold suggestive nodes, May exceed screen range (movable/draggable) or multiple canvas,

3. Library (Pinboard)

1. Store and retrieve graphs or nodes, Options to sort and organize stored graphs and nodes, Search area for stored items

4. Search/Browse Graph (image bellow)

1. Root node + n generations of n children, Movable nodes connected by “wire“, Nodes can be pulled off by force or recombined by drag and drop, Pulled off nodes spawn new systems, Recombination means the node that is dragged into the other becomes a child of the other containing its own keywords + its new parent keywords, Any node of a graph can be commented (the comments itself can be rated), Any node or graph can be shared (with friends on the system or with the Url to pass to friends), Nodes of the same generation can have a different importance (height). This importance could be revaluated by user behavior

2. Plant like

3. After selecting a keyword node it is possible to visualize the content nodes inside of it:

5. Friends Activity

1. History of friends searches, comments and other actions

6. Nodes

1. Keywords Nodes vs. Content Nodes

Beginning Specification

• Personal guidance

• Connection to students from destination countries

• A fitting metaphor to convey the semantically augmented information

Human-like or abstract representation?

How can we make the agent credible and

the user trust in the system?

How intelligent should the agent appear?

In which way should the agent speak with the user?

• Research question

“How does the behavior of an agent influence the expectations of the user?”

• For the experiment :

- Behavior of an agent

- Two DIFFERENT characters

IntegrationPART II: Agents, HCI &Interaction Metaphors

• Idea originated with John McCarthy in the mid-1950’s

• Term “agent” was coined by Oliver G. Selfridge a few years later at MIT

• System that, when given a goal, can carry out the details of the appropriate computer operations and could ask for and receive advice (in natural language)– ‘soft robots’ living and doing their business within the computer’s world

(Kay 1984, via: Bradshaw et al., “Living with agents and liking it: Addressing the technical and social acceptability of agent technology,” in AAAI Stanford Spring Symposium on Human Interaction with Autonomous Systems in Complex Environments, 2003.)

– Fabricate goals of their own– (A. Kay, “Computers, Networks and Education”. In: Scientific American, Sept. 1991)

• They can handle large amounts of data

Agents as HCI Metaphor

• Moves around in the system and „data-mines“ for interesting nodes

• May suggest nodes of interest to the user

• May also augment the discovered nodes with information retrieved from additional databases

• User can direct the agent to a certain node

• Friends agents can interact with each other

http://www.lustiges-taschenbuch.de/typo3temp/pics/24d579190a.png

CEI + Agent

Plants & Animals

• Implement a prototype CEI• User test / usability experiment• Surrounding research

• In the future, agents could:– Connect to other agents to share information and learn– Connect to new databases by automatically “inventing”

queries– Adapt their own ontology over time and in interaction

various individuals– Evolve over succeeding generations

Project Goals & Outlook on the Future

DaVisMo & Confetti

Research questionsHow is it possible to improve the existing interactive, web-based data visualization models in an innovative way?

How can these innovations open the possibility to analyze complex data applied to the students mobility case?

…and they lived happy until the end
