5.0 TECHNOLOGY
How the DuraPoint OEM Module Works
The DOM's innovative design features no moving parts the patented pressure-
sensitive sensor used in VersaPoint technology replaces the troublesome
mechanical assemblies (optical encoders, wheels, rollerballs, etc.) found in
conventional mice and trackballs.
When finger pressure is applied to the DOM's mouse button, the pressure is
transferred to the pressure-sensitive sensor located under the button. The sensor
is divided into four directional zones (up, down, left, right). The pressure
distribution over the four zones determines the direction of cursor movement.
This same sensor also controls the speed of cursor movement a light touch
moves the cursor at a precise crawl while increases in pressure will cause the
cursor to move faster.
When pressure is applied to the DOM's click buttons, it is transferred to a
pressure-sensitive sensor located under the click buttons. The change in pressure
is detected by the DOM's electronics and is interpreted as a click activation. The
click buttons' pressure-sensitive technology have no moving parts to break or
wear out.
