From Visible Past to Visible Effort A research agenda for Web 3.0 technologies Dr. Sorin Adam Matei Purdue University http://matei.org/ithink
The web 3.0 revolution Web 1.0 Push Web 2.0 pull and network Web 3.0 Location aware Information is located in space Information is delivered on the fly You don’t search for information, information searches for you Ubiquitous collaboration On the fly Utilizing implicit user behavior Dynamic reinforcement of collaboration Key collaborative indicators are incorporated in the interface in a direct and telling way
Location aware questions Is information delivered on the fly at a specific place more memorable? Is information contextualized in space more conducive to narrative organization of knowledge? What theories are appropriate in this context? Dual coding? Conjoint retention theory? Theatre/palace of the mind theory?
Ubiquitous collaboration questions What is the optimal structure of collaboration? Is there a way to measure social order online in a synthetic manner? What level/type of collaboration is most conducive to: Learning Efficient production of content What theories are appropriate in this context? Social entropy theory Functional differentiation theory Structuration (norms and resources) theory? Social capital/trust theory?
Learning impacts Is spatially located information more memorable (tentative yes) Is information located spatially in memory (tentative yes) Can “synthetic” spatial environments produce the same learning outcomes as real environments? Matei, S. A., * Madsen, L., Bertoline, G., Arns, L., Ren, M. and Davidson, A. (2006, June). The cognitive impact of location-aware information systems. Paper presented at The Annual Conference of the International Communication Association, Dresden, Germany.
Social impacts Can virtual reality/location aware applications support social ties established with collocated individuals? What is the right mix of social control vs. social freedom in an era of ubiquitous computing? Matei, S. A. * and Ball-Rokeach, S. (2003). The Internet in the communication infrastructure of urban residential communities: Meso or macro-linkage? Journal of Communication. 53(4), 642-657.
Usability questions What kind of experiences best fits specific tasks? Should we deliver multitasking information on the go? Or just simple tasking info? Should we deliver facts or narratives? Right mix of audio, video, text information? Right kind of output/input device/experience? Glanceable interfaces Communicating with colors Importance of physical affordances Relevant theories Narrative theory Affordance theory Satisficing theory Matei, S. A., * Wheatley, D. and Faiola, D.
