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?

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
