The Drawbacks of an Optical Mouse
The optical mouse replaced the old-school mechanical rollerball style mice that we can't seem to find anymore these days outside of antique stores and attics. Dust clogged up those rollerball-type mice and and they were prone to getting “caught” on things or to skid, which dramatically affected performance. The optical mouse solved those problems, using a red Light-Emitting Diode (LED) and optical sensor that relies on images being “offset” or slightly displaced for positioning. But did that solution creat other problems?
Find out whether optical mice work on all surfaces, and try to understand why certain surfaces are better than others.
