WristFlex is an always-available on- body gestural interface. Using an array of pressure sensors worn around the wrist, WristFlex can distinguish subtle finger pinch gestures with high accuracy and speed.
This project was done at the MIT Media Lab with advise from Joseph Paradiso. Thanks to Brad Knox for the help with the machine learning. Cindy Hsin-Liu Kao for helping with the video. Nan-Wei Gong and Gershon Dublon for comments on the paper.
