MTMini: Even Cheaper Multi-Touch

by John Biggs on May 20, 2008

Now that everyone is on the multi-touch bandwagon new systems are popping up all over. Seth Sandler’s solution is fairly ingenious. It uses a piece of paper and a camera to create a camera-based multi-touch interface. All you need is a box, a webcam, and some graph paper and he even includes the demo and application source code.

If you’re a console gamer and happen to have a spare Wii controller laying around, you can build a multi-touch interface out of it:

except that its not a touchscreen, its a touchpad…if it was a touchscreen, you would be touching the monitor and manipulating the screen…not by using the giant home-made mouse.
