4. Identifying Parts and their Functions.
(1) Projector: Uses a red laser to project the image of a
keyboard onto a at surface in front of the typist.
(2) Sensor: Picks up the infrared light reected o the
typist’s ngers and triangulates the location of the
re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
reected o of the typist’s ngers to the sensor.
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
ngers may not be recognize correctly.
