(1) Projector: Uses a red laser to project the image of a
keyboard onto a fl at surface in front of the typist.
(2) Sensor: Picks up the infrared light refl ected off the
typist's fi ngers and triangulates the location of the
refl ected light to determine which key was pressed.
This sensor provides a keyboard function.
(3) IR Light Window: Uses an infrared laser to emit an
invisible plane of light a few millimeters above the
projection surface so that the infrared light can be
refl ected off of the typist's fi ngers to the sensor.
Caution
If one or more of the above modules are blocked by some
cause, the projected keyboard image may not be displayed
