New Google Glass-Like Device To Minimize Eye Fatigue


A lightweight, compact and high-performance Google Glass-like device - called an optical see-through head-mounted display (OST-HMD) - could potentially be “a transformative technology to redefine the way we perceive and interact with digital information”.

For example, it could one day allow a doctor to see computed tomography (CT) images overlaid on a patient's abdomen during surgery or provide a new way to train soldiers by incorporating 3D virtual objects into real-life environments.

AR goggles for long-distance viewing do not always cause eye strain; some of these eye-friendly designs are actively used for military applications.

But short-distance designs - in which you would focus simultaneously on a 2D screen and a 3D world immediately around you - do cause visual discomfort, owing to the so-called accommodation-convergence mismatch problem.

“The eyes are going back and forth between the screen and the three-dimensional scene away from the screen, causing conflicting depth perception cues and visual fatigue,” Hua explained.

“In the new technology, there is no conflict in how your eyes focus, giving you a much more comfortable version of augmented reality,” Hua added in a paper published in the open-access journal Optics Express.
