US Patent 7725511 Bio-metric input mechanism

A biometric keyboard or other input device, such as a keypad or touch screen, may be part of an input mechanism for inputting user information to a computing system. The mechanism may include biometric sensors associated with the buttons or keys of the input device. A mapping scheme may be used such that the input value forwarded to a processing resource when a user activates one or more of the buttons or keys varies depending on which digit (finger, toe, etc.) was used to activate the key(s) or button(s). Other embodiments are also described and claimed.
