CastAR castAR is an [[Augmented Reality]] head-mounted display developed by [[Technical Illusions]]. Similar to other [[AR Devices]], castAR projects 3D renderings onto physical surfaces. To create 3D imageries on top of physical objects, the glasses-like device uses 2 micro-projectors to cast stereoscopic images onto a retro-reflective surface. The images bounce from the retro-reflective surface back onto the user's eyes, creating 3D, holographic-like images floating on the surface. A built-in camera, along with sensors, tracks the movements and the positions of your head. Additionally, an AR/VR clip-on can be placed onto the glasses to create an immersive [[Virtual Reality]] experience. CastARcastAR's Kickstarter Campaign began on October 14, 2013 and raised 1,052,110 dollars out of its initial goal of 400,000 dollars.

castAR began began in the hardware lab of Valve Software in May 2012. Jeri Ellesworth discovered a retro-reflective material that can reflect light back. She realized that the material can be used as a surface to project images onto. Jeri created the first prototype for castAR called "Head Crab". It has 2 phone-sized displays attached to a head-mount. Rick Johnson began working on the software component of the AR project in August 2012. In early 2013, Jeri and Rick left Valve and acquired the technology with them. They formed [[Technical Illusions]] and began working on castAR by themselves. castAR's Kickstarter Campaign began on October 14, 2013 and raised 1,052,110 dollars by its end on September 14, 2013.
