Hi, guys!
So, I was working on designing a game controller that had touchpads instead of analog sticks. The ideia was to simulate the precision of a mouse, like the concept of the Steam Controller. I wanted the pads to be rounded in order to improve the ergonomics of them. I already found some methods to make a plane touchpad like:
- Using a camera: How to make an acrylic designer multitouch pad for 15 bucks - YouTube
- Using multiple capacitive switches: Touch Sensor - YouTube
- Using voltage dividers (didn't understand how this one works): http://hackaday.com/2010/11/16/paper-touchpad/
I also thought about using a mouse optical sensor. Anyways, I was aiming for the most accurate method possible, and one that I can apply to rounded surfaces, so I'm counting on you, guys!
Thanks in advance!
