A simple design of PSOC-based touch control keyboard

We propose a new simple PSOC-based touch control keyboard using the well-developed touch sense technology. The proposed keyboard, designed according to the principle of matrix keyboard, is to use less IO ports to control more buttons than the traditional. We used the CapSense touch sense technology to detect touches on the keyboard, then designed a simple but efficient keyboard scan programme to identify the values of touched buttons. It showed by experiments that the PSOC-based touch control keyboard can do a good work.

Hi,

Is there a schematic for this?

Will it work for sliders?
