Placement for interactive display tables
摘要:
A display table includes a location determination system that determines the location and orientation of each privacy overlay on the display table, and controls the display of private information accordingly. The overlays are portable sheets, akin to placemats, that can be positioned relatively arbitrarily about the display surface.
