Alphabet, which owns the Internet giant Google, gave the presentation of advanced smart glasses Google Glass. In the new version, performance and energy efficiency indicators increased, the camera resolution increased to 8 megapixels. A red diode on the frame now signals the start of shooting, and the accessory itself has become much more ergonomic. All important notifications are sent to the user, and you can now manage points with voice commands. Recall that after the commercial project was frozen more than two years ago, the gadget began to spread exclusively in the manufacturing sector, where it was tested and approved in practice by experts from international corporations DHL, Boeing, Volkswagen. The return of smart glasses can be considered a triumph: Astro Teller, the head of laboratory X at Alphabet, said that all further developments will be focused on the needs of corporate customers. They use Google Glass will bring significant commercial benefits. There is no talk about mass sales of new items.
