Arduino + Processing + Kinect Dimmer
Kinect related projects that involve Processing and Arduino are always so damn cool! Take for instance this latest demo by P&A LAB. They sought out to develop a tracking system that would control a light source by either turning it on/off or dimming the light. They've set up their rig to include some LED lights that represent the amount of dimming that would occur if this product were actually in use. The video shows a linear actuator move according to the gestures used in order to control the amount of dimming the light source would receive.
Some very interesting work is at play here using open source tools such as SimpleOpenNI for Processing. Check out the project page for a bit more detail HERE and watch the video below to see what the heck it is I'm talking about!
