CraigD Posted February 11, 2017 Report Share Posted February 11, 2017 Non-intrusive brain-computer interfaces like the one described in this post rely on EEG – sensing brain activity via small electric voltages on the scalp. Much simpler systems like those described in this article have used EMG – sensing muscle activity via small voltages in the skin over the muscle – to control prosthetic hands and arms. I wonder is a frankly crude EMG-using system could be used to control a video game avatar to create a deeply immersive sense of virtual reality? Here’s what I have in mind:Stick EMG electrodes to the big muscles of your arms and legs, with a few on the little muscles of your hands. Connect the electrodes to an appropriately programmed computerStrap yourself down securely, as is done to restrain an agitated patient or dangerous person, in a chair or bedDon a VR headset, also connected to the computerYou should now be able to attempt to move your arms and legs normally. The EMG sensors will tell the computer that you are attempting to move, while the chair or bed restraint will prevent you from actually moving. The program, however, can move your in-game avatar realistically, which you’ll be able to see via your VR headset. Of course, your proprioception system will detect that your actual limbs aren’t moving, but presented with the false visual evidence from the VR headset, what would you actually experience? Will you feel like you are playing a VR game while strapped down, or will that sensation be overridden by the sensation that you are actually moving as your avatar appears to be?
