Thinking about writing some software to map facial expressions to commands/gestures for ERPing. Would initially be designed for a $5 camera you can affix to the front of the headset and ideally connects to the frunk of your index. Would use basic ML to detect smiles/frowns/tongue out etc. Would be free and youd even be able to set it up with a normal camera if you don’t mind being stationary. Would anybody be interested in this? Only problem is the range of high confidence expressions with a headset on is limited to around only 4 actions.
