Hi there !
This is a kind of consultation for those who know about Capsense.
I would need to build a kind of "matt" to detect multitouch.
It shoul be 10 row for 15 column.
Each of those" Keys" should be arround 1 square inch.
I am wondering it is possible build such " matt" with Capsense and there will not be intolerable amount of interference among keys.
It should be considered that the key form a surface of 15" long for 10" wide.
Thank you very much for any help about that.
Best regards all of you.

A different approach would be a resistive touch-foil. Have a look at this AppNote: www.cypress.com/
Button sizes and cable would fit better than a CapSense keypad.

Hi,
Do you mean to build touch pad or just matrix of buttons ? In touch pads, finger position is calculated and in matrix buttons, which button is touched is detected.
