This VR face mask can read your emotions by Adi Robertson
" ... The new MindMaze Mask, which was announced today, is a ring of electrodes that can be installed in any VR headset’s foam face mask. When you put the headset on, the mask detects which sensors your skin is touching with a certain pressure, then matches the pattern to one of 10 facial expressions, which an avatar reproduces. There’s also some software-based prediction, which is supposed to reduce lag between your face and your avatar’s. It’s not detecting and mirroring every movement — it’s more like you’re pressing button combinations with your face to call up animations. The example avatars are simple cartoons, but they can look like anything a developer wants. ,,,"
