Multiple Views from One Tabletop Display
While most of us primarily use near-vertical monitors, there are some situations that can take advantage of horizontal displays, like Microsoft PixelSense (originally called Surface). Typically these situations involve having multiple people view the display, and even interact with it, which a large tabletop design allows. Researchers at the University of Bristol have now taken this design further by making it possible for one tabletop display to present different information to different people, based on where they are viewing it from.
Personalized View-Overlays for Tabletops (PiVOT) combines two display technologies in the device so users looking on from the side of the display see only the shared view, but those looking down on the display can see personalized information. While the shared view presents a map, the personalized view may instead show details like traffic information. The system also supports auto-stereoscopic 3D images, so 3D models can be rendered in the personal views as well.
A version of PiVOT is going to be showed the Association for Computing Machinery's Symposium on User Interface Software and Technology.
