Hi-Tech leg fun

This week I'll be in Chicago at RIC, Center for Bionic Medicine doing some experiments with neural controls for powered prosthetics.

Today I had 24 EMG sensors on my stump for ~ 6 hours.  We did various iterations of gathering data, traning classifiers, checking classifier accuracy against more gathered test data, then using those classifiers to realtime control a virtual limb.  By the end of the day I was able to fairly accurately control flexion & extension of both my lower leg & ankle ( on a virtual avatar, mechanical devices to come later ).  Very cool stuff.


  1. This is so neat Zac. Though losing the limb is not cool, you are the perfect research patient for these docs. It is so neat that you are a part of paving the way for so many others. Keep the updates coming!
