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. castAR's Kickstarter Campaign began on October 14, 2013 and raised 1,052,110 dollars out of its initial goal of 400,000 dollars.
==Hardware==
===Glasses===
The Glasses has two high-res micro projectors on top of its lenses. The projectors cast stereoscopic images onto a retro-reflective surface. Each projector refreshes at 120 Hz with very high fill factor. This means that the users will not experience any "[[screen door" effect]]. The glasses fit over most prescription glasses.
In the center of the glasses is a tracking camera. The camera is able to track at 120 Hz with low latency. The camera along with the [[Gyroscope]] and [[Magnetometer]] within the glasses enable the user to have 6 degrees of freedom.
===AR and VR Clip-on===
The AR/VR Clip-on allows the user to transform the glasses from a Augmented Reality centric device into a Virtual Reality centric one. When the clip-on is attached to the glasses, the light from the projects are bounced back into your eyes. The retro-reflective surface is not used. It turns the glasses into a [[head-mounted display ]] similar to many other [[VR Devices]].
===Retro-Reflective Surface===
On November 21, 2014, the first shipment of castAR was shipped to Kickstarter backers on November 21, 2014.
On August 19, 2015, castAR receives 15 million dollars in venture capital from [[Andy Rubin]]'s [[Playground Global]] and other investors. Rubin is the creator of [[Android]].
