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

GroupCast in Context
![Page 17: UniCast, OutCast and GroupCast: Three Steps Toward Ubiquitous Peripheral Displays (UbiComp2001)](https://reader036.vdocuments.us/reader036/viewer/2022070301/5447b8c4afaf9f1e708b4637/html5/thumbnails/17.jpg)
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
![Page 18: UniCast, OutCast and GroupCast: Three Steps Toward Ubiquitous Peripheral Displays (UbiComp2001)](https://reader036.vdocuments.us/reader036/viewer/2022070301/5447b8c4afaf9f1e708b4637/html5/thumbnails/18.jpg)
GroupCast Components
• Awareness system (IR badges & sensors)• Profile of inhabitant interests (UniCast)• Group Preference Arbitration algorithm• Input / Output (sense / respond)
![Page 19: UniCast, OutCast and GroupCast: Three Steps Toward Ubiquitous Peripheral Displays (UbiComp2001)](https://reader036.vdocuments.us/reader036/viewer/2022070301/5447b8c4afaf9f1e708b4637/html5/thumbnails/19.jpg)

• OutCast– 1 installation
• Recently integrated with UniCast/GroupCast
• GroupCast– 2 installations
• Arbitration: cycle through profiles of “locals”

Some Open Issues
• Profile integration– Sharing profile information among 3 contexts
• What distinctions are useful?
• Privacy issues
• Profile maintenance– Easier integration with browsing
• Explicit: “Add to Favorites”
• Implicit: browsing history
![Page 25: UniCast, OutCast and GroupCast: Three Steps Toward Ubiquitous Peripheral Displays (UbiComp2001)](https://reader036.vdocuments.us/reader036/viewer/2022070301/5447b8c4afaf9f1e708b4637/html5/thumbnails/25.jpg)
Some Open Issues
• GroupCast: Content selection– Intersecting / complementary interests?
• Anonymous / Random content?
– “Freshness”
• OutCast: Context awareness– Who wants to know?
• Customizing content based on visitors’ ID [badge]
• Evaluation
