Smartglasses and other augmented reality devices, such as Google Glass and the upcoming Oculus Rift, project visual information into the wearer's field of view, and require some finely calibrated microprojection technology to get the job done.
Commercially available systems are currently built around LED light sources, commonly using either a small LED or OLED screen; or liquid crystal on silicon (LCOS) technology with a LED light source. But these may not prove to be the best solution.
