Scientists' iPhone case could electrify mobile gaming

- +

While rumbling gamepads and vibrating steering wheels have been standard equipment since the 1990s, they haven't been able to have quite the same impact on mobile gaming -- power consumption problems see to that -- but a team based in Germany might be about to change all that. 

Using the Muscle-Propelled Force Feedback prototype

Pedro Lopes and Patrick Baudisch of the Hasso Plattner Institute have come up with a way to use precise, painless electrical stimulation to cause muscle movement as part of a mobile gaming experience.

Four electrodes are attached to players' forearms and, in conjunction with a prototype iOS game, can make players involuntarily tilt their phone, creating a sensation of force feedback.

Players using the system find themselves fighting against involuntary movements in their arms and hands. In Lopes's demonstration video, those movements correspond to on-screen events during a flight game.

But this sort of haptic feedback isn't created by a miniature motor. Instead, it's what Lopes and Baudisch are calling "muscle-propelled force feedback."

The system has been booked in for a demonstration at the CHI 2013 conference in Paris, April 27 - May 2, the same congress that members of Microsoft's Kinect team will be attending.
