Unbelievable Homemade MultiTouch Input Device and iPhone Accelerometer Hack

Hacker genius Erling Ellingsen has made his own $2 multitouch input pad from a plastic bag full of blue dye and an iSight camera. He’s also hacked the iPhone’s accelerometer that allows you to control the phone by tipping, rotating or shaking it.

Ellingson’s jury-rigged multitouch input pad lets him control his computer with his fingers, just like the iPhone or Jeff Han’s futuristic multitouch table. Using a bag of die and an iSight camera beneath it, Ellingson can navigate the Web, move chess pieces and play a virtual keyboard. How it works exactly is not clear, but check out the impressive video:

Ellingsen has also hacked the iPhone’s accelerometer, allowing him to control various homemade iPhone applications by tilting, rotating or shaking the iPhone. Ellingsen has created three demo apps controlled by tipping and shaking: a virtual Steve Jobs bobble-head that bobs its head when the phone is shaken; a maze that is navigated by tipping and turning the phone; and a virtual box of balls that roll and bounce as he rotates the phone. Again, see the impressive video:

Ellingsen has released the source code for the iPhone hack, and he’s asking for people to submit their ideas and vote on suggestions for what to do with it.

So far, he’s thinking about an iPod+Nike-like pedometer, a Labyrinth game, SmackBook navigation for Safari and a virtual pet that’s shakeable, among other ideas.
