I'm trying to develop a DDR like dance pad, I'm trying to keep mechanical part simple and cheap as possible, so thought about a solution without moving parts, so this solution appeared.
I never worked with capacitive sensors. Do you think this is possible? Which is the expected latency for this?
My plan is to cut aluminum foil (like roof gutter?) and place on a large wooden board (about 1x1m). One know problem is about the grounding, If I put a wire under this wooden board can solve? Or a full aluminum? (if necessary).
Fo who dont know, DDR is a dancing game, generally a mat with arrows are used as controller, placed in the floor, the arrows appears in the screen syncronized with the music, you need to step on correct arrow and in the correct timing. So, timing is important here. Each arrow will be kind 30x30cm, I need 4 of them + 2 smaller ones (for start and back).
Thank you very much.
