Abstract

A method for transmitting and receiving force information to and from selected keys of a keyboard is described. Feedback is achieved directly to the fingers of the user. This allows alternate or additional feedback from other sources to the user by eliminating the need for audible and/or visual feedback for keys that are pressed. This device is intended to allow software implementers the option of feeding a controllable force back to a user. This device eliminates the need for feedback force springs and switches in the keys. The using software also has an analog input from the user that can express more than one meaning to a single key stroke. For example, a key for cursor movement could be programmed to move at a rate proportional to the force exerted on the key.
