10 years ago you clicked with a mouse, now it’s all about touchscreen – but soon everything will be gesture controlled. Already an available option on some cars (including BMW and Volkswagen) gesture control is set to be the next HMI interface (what will be next!?).
Perfect for when you’re in the car and want to casually skip that embarrassing Spice Girls track you secretly love whilst sat at the lights, or you’re just feeling too happy for Radiohead.
Based around the Microchip MGC3130 3D Tracking and Gesture Controller, Flick boards come in three options for the Pi Zero, the standard Pi HAT format or a larger pad which comes with a ribbon cable to connect it.
I chose the HAT format to see how the Flick board worked. After fixing the HAT to the Raspberry Pi 3 with the provided standoffs, I booted up the Pi. My Pi is currently running Pixel and as this was tested prelaunch I had the files I needed on a memory stick. When you receive your Flick board, just run this line and Flick will be setup and installed:
curl -sSL https://pisupp.ly/flickcode | sudo bash
Once you’ve installed the board, Pi Supply has a flick demo script which reads the output of the HAT. It will output on the screen the actual position of what it's tracking, the reading of the gesture, east-west, north-south etc., touch and double tap.
My favourite, however, is the Airwheel. Scroll your finger round clockwise over the board and it will increase the value, and anti-clockwise left, good for controlling volume or dimmer functions.Conclusion
This is a great addition to my Raspberry Pi and the simplest demonstration I’ve seen of the Microchip gesture control IC in action. If you are looking for a simple HMI for your next Pi project, the Flick board is a great place to start.More
