This is not your kids Etch-A-Sketch for sure
I love me Wacoms as much as I love me bacons, but this Sketch3D–which you can use to draw in three dimensions using three dials and two-color eyeglasses–has got my heart:
Sketch-3D is an interactive, integrated software/hardware system that enables users to create their own anaglyphic 3D drawings. By using a ubiquitous interface metaphor (the “Etch-A-Sketch “), Sketch-3D allows anyone to participate in generating stereoscopic imagery in a way that is simple and engaging. In addition to the personal experience, Sketch-3D can be scaled to work with any output device from large scale projection to plasma displays to an integrated LCD. This versatility allows for Sketch-3D to be tailored to fit a wide array of installation environments.
It runs two applications over a Pico-ITX x86 SBC, a Windows Embedded Standard device. The first one is a service to connect the sensor interface–the three dials–with the main application. The main software is built using the Unity game development environment, with two software cameras that simulate the human eyes. Each camera then displays the Etch-a-Sketch line using red or cyan, which get masked by the classic funky 3D bicolor glasses.
