Diversity of Information Devices• Information devices are diversifying
– Display characteristics– Network bandwidth
– Processing power– Storage Space
Motivation
Tapia 2005 – 10/18/2005
Opportunity
• Most information is designed for display on desktop computers
• Information systems and protocols are geared for dealing with individual devices
Motivation

Opportunity
• Most information is designed for display on desktop computers
• Information systems and protocols are geared for dealing with individual devices
• Users typically carry multiple networked devices
• Potential for co-use of devices for improved information presentations

• Goals– Completeness– Coherence– Coverage– Co-use– Coordination
• Approach: Decouple– specification from information content– information content from presentation

Systems and TechnologyResults
• Architecture for distributed information presentation over a set of devices
• Policies and rule-bases for effective cross-device information presentations
• Working system that integrates personal devices for anywhere information access

Tapia 2005 – 10/18/2005
Theory and PublicationsResults
• Understanding of the perceptual factors– Nature of information– Transformations for rendering on various devices
• Understanding of cognitive issues involved in the co-use of devices
• Papers, papers, and more papers…and a dissertation

The Big PictureResearch Significance
• The end of “one size fits all”– Information representation– Authoring and specification– Support for infinitely diverse devices
• OLEDs
• Authoring support for small devices
• Cross-form information transformations– Text ↔ audio– Text ↔ image?– Video?
Tapia 2005 – 10/18/2005
The Bigger PictureResearch Significance
• Societal effects– Transformation in communication– Work practices– Collaboration
• Cascade effects– Improved information representations– Digital preservation
Tapia 2005 – 10/18/2005
May the Force be with YouLessons Learned
• The longer you think about it– More crystallized problem– Additional dimensions
• This… and this… and this… and that too…
• There is always more to be done
