With the brewing interest and brouhaha over Google Glass in the past few months, it comes as no surprise that there are comparable HMD technologies that are up in arms to compete against the internet giant. The K-Glass designed by the researchers at the Korean Advanced Institute of Science and Technology (KAIST) can certainly be counted among these band of competitors. However. the hands-free contrivance does stand out in few crucial aspects, especially when it comes to its energy efficiency scope. In fact, the wearable is touted to consume about 76 percent less power than ‘other devices’, with its effective power-train fueled by a 65nm augmented reality chip. In terms of solid figures, the K-Glass has the peak capacity of achieving 1.22 TOPS (tera-operations per second) at 250 MHz, which amounts to 778mW on a 1.2V power supply.
