4. Identifying Parts and their Functions.
(1)
Projector: Uses a red laser to project the image of a keyboard onto a flat surface in front of the
typist.
(2)
Sensor: Picks up the infrared light reflected off the typist’s fingers and triangulates the location
of the reflected 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 reflected off of the typist’s fingers
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 correctly or, the location and movement of the typist’s fingers may not be
recognize correctly.
