Expression tracking system

What about expression tracking, which would require eye cams and a mouth tracking camera being built into the rift.

Then your avatar could reproduce your expression, in game?

Actually games without VR could do this with a simple webcam and a facial/expression recognition system.

I think it could really improve the immersion in games.

With voice recognition (+microphone) and ideally voice synthesis, so your character doesn't have to have your voice but says what you say.

Actually if voice recognition could decode what you're saying and convert it into text this could be great as the game could then apply Filters and award in character acting and punish bullies in game (whilst reducing VOIP traffic).

OK So a future Rift will need facial/expression recognition, voice recognition and synthesis.

Not a lot to ask for is it?
