The castAR team has just shipped its first pair of augmented reality glasses, a year after it raised $1 million on Kickstarter. This headset, developed by a group headed by ex-Valve engineers Jeri Ellsworth and Rick Johnson, features active shutter glasses, a camera for input and a projector that displays 3D images onto a surface. Its developers call the device "the most versatile AR and VR system," but its strength lies in augmented reality (digital display superimposed against the real word) -- you can't even use its VR functions unless you also get the optional clip-on. When we interviewed the developers and tried out the latest prototype, we noticed a number of improvements from previous versions, including brighter and crisper images and a lighter design.
