Sweet - Kinect Hack & A Digital Canvas That You Paint With Your Fingertips | via Co. Design

"Soak" uses the Kinect to "grab the topology data of the screen in real-time, which is then translated into a 3-dimensional deformation structure," designers Hyunwoo Bang and Yunsil Heo tell Co.Design. In other words, when you press your fingertip into the stretchy membrane, the Kinect can sense the change in depth of the screen, which it then sends to Bang and Heo's software, which generates a visual simulation of ink gently spreading out from the spot you touched. And that, not the 3-D-sensing, was the hard part, according to Bang and Heo: "What was challenging to us in this project was simulating the dying process based on real-world physics," they say. "The simulation itself includes complex phenomena like capillary smear through the pulps with diffusion and delivery of pigments. What was more, the simulation had to be updated [at HD resolution] at least 60 times per second for its real-time application."
