A team of engineers at the University of Utah wants to take haptic feedback in game controllers beyond just the standard "rumble."
They've installed mini-thumbsticks called "skin stretch tactors" inside a controller's regular thumbsticks, and the movement of the tactors can provide specific feedback and cues in response to in-game action.
The tactors can nudge you to move in a particular direction, let you know how close an explosion is to your character, or -- as in one of the university's demo games -- represent the pull of a fishing line.
They can also scale their feedback based on the position of the controller's full-sized thumbsticks, which keeps them from interfering with the gameplay experience.
Should skin stretch tactors be part of the controller of the future, or would you rather stick to rumble?
