Knock Block: a modern knocking framework
Man has long wrestled with Time. Also, with knocking on things and not getting the time of day. We propose a knocking platform through which these fundamental needs are met. This is illustrated with the Knock Block KUI and accompanying Clock Knock Block application. The Knock Block possesses realistic knocking action with a human-like variation in frequency and amplitude of knocks.
Just knock on the Knock Block, or even the surface on which it's resting, and it will knock back the time to you. First it will knock the number of hours, and then the quarter hours.
If you knock several times, the Mock Knock Block application will take over, and repeat back your knocking pattern.
