Touch Screen with Force Sensor

I came across a good photo disclosing the internal structure of a touch screen using force (pressure) sensors. As shown in the figure below, the sensor is placed on the perimeter of the display.

This is a video clip of a working demo of the above force sensing touch screen. The touch screen was jointly developed by Pressure Profile Systems and MIDT.

I also found another mobile application of PPS tactile sensors at PPS site.
