Smart glasses will show you a video, without killing the battery

Smart glasses with camera "is not soared" for several reasons. Whether it's clunky design, the ban or simply a lack of practical application, on the streets until the smart glasses nobody goes. There is another but: smart glasses need a big battery that will maintain the video streaming, which means glasses are bound to be enormous. It's no joke: even a smartphone charge lasts barely a day, but the smart phone - rather big invention. But there is a solution. Scientists from the University of Washington built a streaming method, which consumes up to 10 000 times less energy than traditional methods. The trick is to unload much of the hard work to another device, using a smart wireless transmission.

Smart glasses will show you a video, without killing the battery

Typically, the camera usually has to process and compress video before transmission over a wireless network. The new approach is directly attaches the pixels from the camera to a wireless antenna and uses the backscattering (ie reflection of signals transmitted to the device) to send data to a pulse on the nearest phone or PC, which takes care of the processing. Devices that use backscattering already exist, but have so far been limited to applications of the sensors, of limited small volumes of transmitted data; new approach also can handle video in 720p. In the near future you will not have to distribute video from your smart points. The current experimental prototype smart glasses is limited to 10 frames per second at distances up to six meters. But their practical application is already quite obvious. You will be able to wear glasses and smart wearable camera with much smaller batteries or no batteries at all if they will receive power from the radio (yes, this is possible and has already been used). And this, in turn, could lead to wearable cameras in unusual places. Scientists already are sports matches, where each athlete hanging in his buttonhole camera, which does not burden it. Sports camera in the first person can be a new form of entertainment.
