Dualshock 5, Sony Interactive Entertainment’s next-generation controller for PS5,* will seemingly be using biofeedback to modify user-experience. According to a new Sony Patent, the controller will feature sensors to gather biofeedback from the user’s hands during normal use.

The sensor on one or both sides of Dualshock 5 grips are going to track electrodermal activity (sweat secretion) and heart-rate. The biofeedback will then be used by the PlayStation 5 to make adjustments to a user’s gaming experience. How exactly will this happen and what changes we can expect is unknown.
