Pretty good idea, could be useful for VR especially, especially for haptic feedback, anyone who's played VR knows you don't need yet another object stuck to your face or head as it get's really hot as it is!

I would love to have VR games take advantage of haptic sin a device like this imagin playing a horror game and feeling a tap tap tap in the shoulder and have a monster stares at you or feeling those bullets flying by you in a FPS
