PIEZOELECTRIC SENSOR ASSEMBLY FOR WRIST BASED WEARABLE VIRTUAL KEYBOARD

摘要

The subject matter described here addresses the concerns set forth above at least in part by wrist based wearable virtual keyboard which may be used with electronic devices. The wrist based wearable virtual keyboard may comprise a member which may be adapted to fit around a wrist of a user. The member may comprise a plurality of sensors positioned to generate signals in response to parameters such as motion, orientation, or position of the user's hand and fingers. A controller is coupled to the sensors and includes logic to analyze the signals generated in response to movements of the users to associate a symbol with the signals. In one example a holder for a piezoelectric sensor comprises a body comprising a first surface and a second surface, opposite the first surface and a recess formed in the first surface of the body to receive the piezoelectric sensor.
