Augmented Reality Glasses to Transform Vision

The emphasis on vision correction in context is interesting.

DARPA Awards $4.7 Million Grant to Transform Augmented-Reality Glasses 
Military Embedded Systems   By Lisa Daigle

Researchers at Columbia University, Stanford University, and the University of Massachusetts at Amherst have won a $4.7-million U.S. Defense Advanced Research Projects Agency grant to develop a lightweight glass that dynamically monitors the wearer's vision and displays vision-corrected contextual images. The goal is to create an ultra-high-resolution, see-through, head-mounted display with a large field of view and significantly reduced size, weight, and power consumption. The device also will be correct the user's vision deficiencies in real time and project aberration-corrected visible contextual information onto the retina. The augmented reality glass relies on the ultrafast generation of arbitrary wavefronts, both in visible and near-infrared wavelengths. The researchers will develop a scalable fabrication process based on standard complementary metal-oxide semiconductor techniques, and well-established procedures to integrate the new materials into the silicon nitride-integrated photonics platform. The team will develop analytical and computational tools for modeling large resonator arrays and dynamics of device performance.... "
