DIY hand-based 3D input
If you've ever felt the burning desire to give your index finger a little more prominence in your day-to-day computing exercises, here's your chance. A DIY'er has combined an IR-based, homemade tracking system with a piece of software that he's coded which can translate the IR data into 3D navigation. So far, the system can track the movement of two hands using six individual points (we assume one per axis, per hand). Details are scarce on the project right now, but the prospect of manipulating onscreen images or spaces in three dimensions with a cheap and simple solution is definitely enticing. Check the video after the break to see a finger in action.
