Slippers explore alternative input

Hannah Perner-Wilson is exploring alternative sources of input through wearable suits and footwear. Her latest project, Joy Slippers, plays a soundscape that you control through your foot movements. "These slippers are designed with two pressure sensors embedded in each sole and can sense the weight being shifted between the toe and heel of each foot. This information is fed into a computer where a drawing application translates this analog input into drawing directions, so that the wearer of the Joy Slippers can draw with their feet in an etch-a-sketch fashion." Here's a video of it in action:
