Motion-based user input for a wireless communication device

A method of operating a mobile station comprising:

• detecting a user-generated motion associated with the mobile station;
• and
• implementing one of initiating a call to a user-selected recipient, answering an incoming call, or terminating a call responsive to detecting the motion.

A method of generating a motion signal in a wireless communication device comprising:

• generating an output electrical signal in a vibration circuit responsive to user-generated motion associated with the wireless communication device, wherein the generated output electrical signal is directly related to the motion of the wireless communication device;
• and
• processing the generated output electrical signal to detect the motion.

A wireless communication device comprising:

• a motion sensor to detect a user-generated motion;
• and
• a function processor configured to execute responsive to the detected motion a pre-selected function associated with the detected motion.

A mobile station comprising:

• a motion sensor to detect a user-generated motion associated with the mobile station;
• and
• a communication processor configured to implement at least one of initiating a call with a user-selected recipient, receiving a call, or terminating a call responsive to the detected user-generated motion.

A motion sensor in a wireless communication device comprising:

• a vibration circuit configured to generate an output electrical signal responsive to user-generated motion associated with the wireless communication device, wherein the output electrical signal is directly related to the motion;
• and
• a processor configured to detect the motion based on the output electrical signal.
