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. As The images bounce from the retro-reflective surface back onto the user's eyes, the user sees 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. CastAR's Kickstarter Campaign began on October 14, 2013 and raised 1,052,110 dollars out of its initial goal of 400,000 dollars.
