Sight for sore eyes: Augmented reality without the discomfort

May 28, 2014 11:08 am | News | Comments

One major limitation of augmented reality (AR) devices such as Google Glass is that moving back and forth between a 2-D image on a screen and the 3-D real world can cause eye strain unless the object of focus is far away. A new device under development should make AR technology easier on the eyes for short-distance applications, too, by superimposing 3-D images instead of 2-D.
