Yes hardware startup are sexy, but most of them are also very software-intensive. Leap Motion needs a lot of processing power, even for a simple visualizer app, and I bet Myo does too.

Other examples: guidance of things like the Sphero or the Parrot AR Drone are very complex. Usually there's a lot of maths involved, which has to be translated into software.

I would think they just map muscle contractions to commands for the drones. No math required except to parse contractions.

Electrical input from the body is extremely noisy. I wouldn't be surprised if they were using machine learning to train their algorithm to recognize which electrical patterns correspond to which muscles being activated.

The math behind this is actually rather complex. Heavy duty machine learning and statistical analysis.

Well of course. But that's DSP for parsing the muscle contractions, right?

I would imagine you guys didn't do any application-specific math like guidance of the choppers..? Just curious!
