Smart glasses could stream video without killing your battery

There a number of reasons why camera-equipped smart glasses haven't taken off, whether it's dorky designs, bansor just a lack of practical applications beyond niche audiences. However, there's a common theme for them all: they need big batteries to handle all that streaming video, which guarantees a bulky set of spectacles.

There mightbe a solution in the long run, however. University of Washington researchers have crafteda video streaming method that consumes up to 10,000 times less power than traditional methods. The trick, the team said, is to offload most of the hard work to another device using clever wireless transmissions.
