20. A method comprising:
-
directing an optical signal into an optical carrier that is affected when force is exerted on a touch-sensitive display; directing a reference optical signal through a reference optical carrier that is not affected when force is exerted on the touch-sensitive display; when a difference between the optical signal and the reference optical signal meets a threshold, signifying force imparted on the touch-sensitive display. - View Dependent Claims (21, 22)
