At SIGGRAPH 2015 there were a couple demonstration booths where groups had stuck sensors and/or cameras to VR googles and used them to render expressions on your avatar's face. Here's a demo from one of the groups: https://www.youtube.com/watch?v=rgKkEnaaSDc https://www.youtube.com/watch?v=rgKkEnaaSDc - they used strain gauges inside the goggles to track muscle movement of the upper face, and stuck a camera on a stick hanging off the googles to capture lower face movement. Here's another one that uses photo-reflective sensors attached to a set of eyeglasses, which can be worn inside a VR headset. For this demo I had to remove my prescription glasses, so it was unfortunately quite hard to say how well it worked! https://vimeo.com/132772990 https://vimeo.com/132772990
