UniCast, OutCast and GroupCast: Three Steps Toward Ubiquitous Peripheral Displays (UbiComp2001)

Joe McCarthy, Tony Costa, Edy Liongosari UniCast, OutCast, GroupCast: Three Steps Toward Ubiquitous Peripheral Displays

Motivation(s)
We often talk/hear about a world filled with displays
“ Walls in our offices & homes will be reactive displays”
Andries Van Dam, CACM, March 2001 (The Next 1000 Years) “User Interfaces: Disappearing, Dissolving, and Evolving”
Everywhere Displays
Claudio Pinhanez, UbiComp 2001
What will such a world be like?
What kind of content would be put on such displays?
How will the content be affected by (react to) context?
UniCast, GroupCast & OutCast
Three steps toward ubiquitous peripheral displays
All UbiComp applications are approximations…

Peripheral Displays in 3 Contexts
UniCast
Inside one’s office
Interesting, non-urgent content for yourself
OutCast
Outside one’s office
Content for visitors
GroupCast
In a public space
Conversation starters

OutCast: About Me

OutCast: Where Am I?

OutCast: Calendar

OutCast: Demos

GroupCast in Context

GroupCast
A system for the public display of content that is of mutual interest to passersby
Provide opportunities for conversation
Especially for conversationally-challenged (nerds)
Increase sense of “community”
Location matters -- what can we do for physically collocated workers?
Faceless names, nameless faces
Dynamic, project-oriented teams
Lay the groundwork for collaboration
More likely to collaborate with people I know

GroupCast Components
Awareness system (IR badges & sensors)
Profile of inhabitant interests (UniCast)
Group Preference Arbitration algorithm
Input / Output (sense / respond)

Status
UniCast
~10 installations (users)
Demand > supply
Variety of hardware configurations
OutCast
1 installation
Recently integrated with UniCast/GroupCast
GroupCast
2 installations
Arbitration: cycle through profiles of “locals”
