A British company has developed a prototype pair of augmented reality glasses, which could give Google’s Project Glass a run for its money.
The new augmented reality glasses, from Cambridge-based TTP, work by projecting light onto the lens at an angle of approximately 45 from a miniature projector mounted on the arm. The lens is embedded with a “grating structure” that redirects light into the eye.
This means that images and text can be superimposed directly onto the wearer’s field of vision when they look straight ahead – unlike Google Glass, which puts a small video screen in the bottom right-hand corner of the right eye, forcing the wearer to glance down constantly.
