A piece of glass with tiny little bumps on it can be used to identify objects. The “smart glass” could eventually be more compact than using cameras and computers to achieve the same aim.
Machine learning algorithms are becoming good at identifying objects, but using them usually requires a camera and a computer. While this combination fits inside your phone, at Columbia University in New York and his colleagues wanted to make an even smaller object recognition device.
To eliminate the need for a…
