Using a piece of Conductive Acrylonitrile Stretch Glove to make a simple fabric touchpad.
The knit contains a resistive thread that goes from left to right, top to bottom. this allows me to measure the placement of the finger (which is supplying current) by measuring the output at all four corners.
You might have seen it on Instructables. It costs near nothing to make, if you already have an arduino or another a/d converter and some wire. The anti-static gloves don't cost much.

i guess if you were to pulse at different frequencies or something to differentiate between contact points...
or else, you could track more than one point and points would create a shape, but you wouldn't get any sensitivity within the shape. i think.
