Optical Mouse
An optical mouse is an advanced computer pointing device that uses a light-emitting
diode (LED), an optical sensor, and digital signal processing (DSP). Movements of the
mouse are detected by sensing changes in the reflected light, rather than by interpreting
the motion of a rolling sphere as with a mechanical mouse.
Tips for correct use
The optical mouse takes microscopic snapshots of the working surface at a rate of more
than 1,000 images per second. If the mouse is moved, the image changes. The smallest
irregularities in the surface can produce images that are sufficient for the sensor and
DSP to generate usable movement data.
Considering the way the optical mouse works:
■ Avoid mouse pads that are very glossy or highly reflective.
■ Avoid dark mouse pads.
■ Use your mouse on colors such as white, tan, or grey.
■ Use your mouse on surfaces with a flat, non-reflective finish.
■ Use your mouse on surfaces that reflect but also scatter the light, such a a white
sheet of drawing paper.
Note: If you experience erratic mouse behavior, test it on a plain white sheet
of paper.
