Could the next version of Google Glass use … AA batteries? Unlikely, but it’s entirely possible, especially if Google’s latest patent for Glass is anything to go by. The company filed for a patent that sees a number of pretty major changes to the design of Google Glass, not only changing the source of the device’s power, but also changing how users would control it. As part of the newly filed patent, Google Glass would have a control panel mounted on one of the arms. The panel, according to the patent, is basically a touchpad that would house an electronic circuit and a power source. On the end of the arm would also be found another parts housing. This housing may also contain other components, such as a processor, communications devices, Bluetooth chip, and so on.
