PiVOT is a personalized view-overlay that is meant to encourage mixed-focus collaborative tasks.

 

A team of scientists led by the University of Bristol in the UK have developed a system called PiVOT (personalized view-overlays for tabletops). Designed to encourage and support mixed-focus collaboration, the display system shows users an undistorted shared view as well as their own personal view at the same time.

It supports multiple personalized views, which can be present at the same spatial location and yet only visible to the user it belongs to. PiVOT also allows the creation of personal views that can be either 2D or auto-stereoscopic 3D images. Sriram Subramanian, Professor of Human-Computer Interaction, said:
