Plusea shows you how to make slipper that you can “draw with” –
This Instructable will show you how to make a pair of cozy slippers that are designed with two analog inputs each that sense the pressure being weighted from the body on either the toe-ball or the heal of the foot.
Later steps in this Instructable will show you how to feed this analog input into your laptop via an Arduino physical computing platform. There are many things that you can do with this input, and I hope to bring out a few interesting applications in the next weeks. This Instructable features a simple drawing application that allows the wearer to control the direction of a line being drawn in real-time and thus draw, using the weight on their feet, in a very simple etch-a-sketch fashion.
