I'm thinking about building my own DIY omni threadmill but would need foot tracking. Ideally precise foot tracking.
Gluing two extra touch sensors on top of the front part of two shoes should be relatively simple, but can you actually read four touch controllers at the same time with one rift setup?
So can you pair 4 touch controllers and get all the positions of all four from the oculus SDK? Otherwise it's no use buying 2 extra touch controller.
