Title: What is "ghosting" ?
Post by: TrickyFishy on July 08, 2003, 03:08:19 pm

I was thinking of trying a keyboard hack and have seen people mention ghosting problems.

What exactly is ghosting?

basically, keyboards use matrix'es (matrices). if 3 buttons in a right triangle are pushed, the fourth key that makes it a square is pushed.

example:

on a fake key matrix (i dunno if this is the location of each key)

A    D
B    C

if buttons A, D, and B are pushed, C will be pushed even if you never touched it. that is "ghosting"
