How your interactive projector works
The LightRaise 60wi interactive projector is a unique finger and pen touch solution. A specially filtered
infra-red camera and signal processor, embedded in your interactive projector, can track up to two
fingers or two pens simultaneously. The Touch Detection Module (TDM), located immediately under
the projector boom, generates a tightly controlled infra-red light beam very close to the surface. The
infra-red camera detects the reflection from your finger or the glow from the active pen when you
touch the surface. The system can differentiate between fingers and pens, enabling you to write with
a pen and move objects with a finger at the same time. In addition, the active tip in the pen is
synchronized with the TDM and ensures the pen writes only when in contact with the surface.
Because the interactive technology is located in the projector and the TDM, and not in a board, you
can turn almost any reasonably flat surface—a common dry-erase board or even a bare wall—into an
interactive surface.
