ABSTRACT:
A system, method, and computer-readable medium having instructions for determining a key press from a current keyboard state at a current time is described. The system stores signals indicative of a last key press, a last key press time, and a last keyboard state. The system determines released keys and pressed keys on the keyboard at the current time based on comparison with the last keyboard state. The system determines a key press at the current time if the first determination determines a single key press and if either of: (a) a match exists between the determined key press and the last key pressed and if the elapsed time between the current time and the last key press time is larger than a preset bounce time; and (b) a match does not exist between the determined key press and the last key press.
