Smart glasses with the camera “did not take off” for a number of reasons. Whether it's a clumsy design, a ban or just a lack of practical application, on the streets while smart glasses no one goes. There is one more thing: smart points need a large battery that will support streaming video, which means the glasses will be huge. Whether a joke: even a charge of the smartphone suffices hardly probable for a day, and the smart phone – rather big invention. But there is a solution. Scientists from the University of Washington have built a method of streaming, which consumes up to 10,000 times less energy than traditional methods. The trick is to download most of the heavy work to another device using smart wireless transmission.
Conventional cameras usually have to process and compress video before transmitting over the wireless network. The new approach directly attaches pixels from the camera to the wireless antenna and uses backscattering (i.e., reflection of signals sent to the device) to send data impulsively to the nearest phone or PC that will take care of the processing. Devices that use backscattering already exist, but have so far been limited to applications of sensors limited by small amounts of data being transmitted; The new approach can handle video at 720p.
In the near future you will not have to distribute video from your smart glasses. The current prototype of experimental smart glasses is limited to 10 frames per second at distances of up to six meters. But their practical application is already very obvious. You will be able to wear smart glasses and wearable cameras with much smaller batteries or without batteries at all, if they will receive energy from radio signals (yes, this is possible and has already been used). And this, in turn, can lead to the appearance of wearable cameras in unusual places. Scientists already represent sports matches, where every athlete has a camera in a buttonhole that does not burden him. First-person sports cameras can be a new kind of entertainment.
