When Valve's first hardware hire, Jeri Ellsworth, tweeted back in February that she was fired from the company, we were disappointed but also intrigued by what she meant by "time for new exciting projects." Well we finally saw what she's been up to here at at Maker Faire 2013. It's called Cast AR, and it's a pair of 3D augmented-reality glasses that she and former Valve programmer Rick Johnson were working on at Valve before they left.
The model we saw is still in the early prototype stages, but the concepts are already in place. Perched atop a pair of active shutter glasses are a couple of miniature LCD projectors, which bounce images from a connected computer onto a special reflective surface at a 120Hz refresh rate. A camera module sits on the eyewear's bridge and monitors an array of infrared LEDs embedded in the reflective surface. This allows for quick and accurate head tracking. Join us after the break for our impressions and stay tuned for our video interview with Jeri Ellsworth.
