To provide navigational help for the blind, Caltech researchers have combined augmented reality hardware and computer vision algorithms to create a portable headset that translates the optical world into plain English audio. The work was done in the laboratory of Markus Meister (Ph.D. ’87) who is an affiliated faculty member of the Tianqiao and Chrissy Chen Institute for Neuroscience at Caltech, an Anne P. and Benjamin F. Biaggini Professor of Biological Sciences and executive officer for neurobiology.
