New projector glasses castAR have achieved over $1.5 million funding on crowd-funding website Kickstarter.

The glasses, created by Rick Johnson and Jeri Ellsworth of Technical Illusion, are a projected augmented reality system that works using only the glasses and a surface.

The frames of the castAR glasses contain two micro-projectors, which cast a perspective view of a stereoscopic 3D image onto the surface. The eye then focuses on this projected image at a natural viewing distance.

A tiny camera placed between the two micro-projectors is used to scan for infrared identification markers placed on the surface, which it can then use to track the users head position. This enables the software to accurately adjust how the holographic scene should appear to them.

The creators also claim to offer an attachment that will transform castAR into a true virtual reality system as well as an augmented reality system, with potential gaming applications.

As well as the micro-projectors, the creators also designed two peripherals. The first, the Magic Wand, is used to position things in space and control then with a joystick. The second, the RFID Tracking Grid, allows users to identify, track and augment physical objects across a surface.

The castAR projector glasses are expected to be launched during 2014.
