1) Capacitive and also projected capacitive touch screens detect user touch by change in capacitance. 2) Wearable signal generator is used. Electric signal fades while is passing through the user body. Different distances from the signal generators placement to the fingertips provide different path losses. Electric signal generator as the ring on the thumb or little finger is proposed but not limited. 3) If user touches the screen with fingertip then different level of signal inflicts different distortion on the touch screen surface. 4) Touch screen shall distinguish different levels of distortion, recognize coordinates, and which finger was used.
