For a seamless user input solution that differs from the ordinary pushbutton, try the Touch Keypad Phidget. It works like a smartphone’s touchscreen, sensing the change in capacitance as your finger comes near. As such, you can place the Touch Keypad Phidget behind up to 3mm of glass or plastic, allowing you to enclose the hardware to make the panel child-friendly and aesthetically pleasing.
With seven capacitive touch regions, you can assign different functions to each with events in our API. You can also detect the proximity of a finger before contact is made, and you can adjust the sensitivity to improve performance in your application. If an object stays on a region for sixty seconds, the board will recalibrate and ignore that object until it is removed. This feature prevents regions from being locked by unintentional objects like dirt or debris.
