ThinSight is a thin form-factor interactive surface technology
based on optical sensors embedded inside a regular
liquid crystal display (LCD). These augment the display
with the ability to sense a variety of objects near the surface,
including fingertips and hands, to enable multitouch
interaction. Optical sensing also allows other physical items
to be detected, allowing interactions using various tangible
objects. A major advantage of ThinSight over existing
camera and projector-based systems is its compact form-
making it easier to deploy in a variety of settings. We
describe how the ThinSight hardware is embedded behind
a regular LCD, allowing sensing without degradation of display
capability, and illustrate the capabilities of our system
through a number of proof-of-concept hardware prototypes
