Engadget | Face and ‘effort’ controlled iPad game helps you outrun the competition.

If you’re looking for some exergaming action, but don’t have the rhythm — or lack of self awareness — for some existing sport game accesories, how about a game controlled by effort? Using your iDevice’s camera and accelerometer, BitGym has created a control system for playing iOS games while on your exercise equipment of choice (possibly not the trampoline though). The first release is a racer that converts rate of exercise to acceleration and head movement to steering. We’re told there’s an SDK too, so developers looking to trim-up can make their own gym-distractions. Fit Freeway is available now, but if you want to see it in action, without breaking a sweat jog on over the break for a demo video.
