The web 3.0 revolution<br />Web 1.0<br />Push<br />Web 2.0<br />pull and network<br />Web 3.0 <br />Location aware<br />Information is located in space<br />Information is delivered on the fly<br />You don’t search for information, information searches for you<br />Ubiquitous collaboration<br />On the fly<br />Utilizing implicit user behavior<br />Dynamic reinforcement of collaboration<br />Key collaborative indicators are incorporated in the interface in a direct and telling way<br />
Location aware questions<br />Is information delivered on the fly at a specific place more memorable?<br />Is information contextualized in space more conducive to narrative organization of knowledge?<br />What theories are appropriate in this context?<br />Dual coding?<br />Conjoint retention theory?<br />Theatre/palace of the mind theory?<br />
Ubiquitous collaboration questions<br />What is the optimal structure of collaboration?<br />Is there a way to measure social order online in a synthetic manner?<br />What level/type of collaboration is most conducive to:<br />Learning<br />Efficient production of content<br />What theories are appropriate in this context?<br />Social entropy theory<br />Functional differentiation theory<br />Structuration (norms and resources) theory?<br />Social capital/trust theory?<br />
Learning impacts<br />Is spatially located information more memorable (tentative yes)<br />Is information located spatially in memory (tentative yes)<br />Can “synthetic” spatial environments produce the same learning outcomes as real environments?<br />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.<br />
Social impacts<br />Can virtual reality/location aware applications support social ties established with collocated individuals?<br />What is the right mix of social control vs. social freedom in an era of ubiquitous computing?<br />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.<br />
Usability questions<br />What kind of experiences best fits specific tasks?<br />Should we deliver multitasking information on the go? Or just simple tasking info?<br />Should we deliver facts or narratives?<br />Right mix of audio, video, text information?<br />Right kind of output/input device/experience?<br />Glanceable interfaces<br />Communicating with colors <br />Importance of physical affordances<br />Relevant theories<br />Narrative theory<br />Affordance theory<br />Satisficing theory<br />Matei, S. A., * Wheatley, D. and Faiola, D. (2006, June). Multipurpose mobile devices, graphic user interfaces, and physical affordances: A Case Study.
