4.6 Touch Gestures
4.6.1 Project Description
This example project demonstrates the touch gesture recognition capability of the PSoC 4200M device using the CapSense
Gesture Pad. This Gesture Pad has five buttons arranged similar to a joystick.

The project gangs all the five CapSense elements of the Gesture Pad and scans them together as a single proximity sensor
every 100ms by default. When the ganged proximity sensor detects an approaching finger, PSoC 4200M turns on the RGB
LED and decreases the scanning interval to 10ms. When a finger touch is detected, the firmware tries to recognize if the
finger has performed any touch gestures. The PSoC 4200M changes the color of onboard RGB LED in different patterns
depending on the detected gestures.
Table 4-2
shows the different gestures recognized by the firmware and the
corresponding output action for each gesture.
