This is basically the electronics for a standard USB keyboard, without the keys. It scans the switches you attach to it and sends the appropriate messages back to the computer.This opens up many posibilities.Obviously you could build your own standard keyboard.Or you could build a subset of keys used in a particular game in the exact layout you want.Or a custom set of keys for that CAD program or desktop publishing program you use.Or a media control station using just the media control functions with whatever other keys you might need. With just a little more electronics you could have a rotary encoder as a volume control. Think of a keyboard with a volume control knob.The switches could be any type of switch so the keys might be customised to allow a disabled person to use a computer (or play a game using a subset of the full keyboard). Things like pressure switches, microswitches, foot switches, tilt switches or even a rotary encoder (with a little extra electronics). Customised to a person's particular capabilities.There are many posibilities.This is good.
