Emulating Touché

In 2017, I worked on a project where I built a circuit that emulated the Touché circuit from Disney Research.

I wanted to see if, using the circuit and machine-learning software, I could replicate the results of the Touché paper by training a system to detect how I was touching various plants, or how to use water as an interface.

I wrote about these experiments in Touché, and Water as an Interface, and Talking to Plants: Touché Experiments.
