1-key USB keyboard
5. December 2008 - 19:54 — adminThe idea for a 1-key keyboard comes from the need as an interaction designer to make “cheap, quick and dirty prototypes.” When creating a quick screen-based demo in e.g. Adobe Flash, a common way of quickly prototyping physical actions is to assign actions to certain key presses on a keyboard.
Stealth USB CapsLocker
