Minority Report style computing, one step closer :
MS released Surface (presented above as on what looks like 80s table-top-style video game). Apple has already previewed the iPhone with similar touch surface interaction. I recently presented a concept brief for an museum exhibition that made use of dialogue tables. (That I proposed would interact with RFID tags.)
People seemed to doubt this would work. But here it is all grown up with Surface.
I think we’ll see this a lot more in museum and exhibition presentation settings. More so than even hotels and restaurants as Core77 suggests.
