Looks like you control it with your big toe via a pressure sensor inside a shoe? Sounds cool!
- ampdepolymerase 5y agoI am surprised they didn't use electromyography bands which are a perfect fit for this particular application (like those by Ctrl Labs and Thalmic labs). Perhaps their budget didn't allow for making custom amplifier chips.

- aroberge 5y agoI disagree: I find that she makes an excellent point about the choice she made in the video linked above. She is a designer, exploring ideas about body augmentation. She is not (and nor is anyone else) at the stage of perfecting a design so that it become the most performant. "Premature optimization..." and all that.
