While Google may have grabbed headlines for its recent wearable tech, Olympus is doggedly forging ahead with its own prototypes, seven years on. Unlike Project Glass, the MEG4.0 isn’t a standalone structure and needs a glasses frame to hang on, although the sub-30g unit shouldn’t tax it too much. The QVGA (320 x 240) display can connect to devices through Bluetooth 2.1, with Olympus pointing to a smartphone hook-up to provide both the processing power and internet connectivity — which sounds different to what we’re expecting from Google’s effort. The current prototype can squeeze out eight hours of intermittent use, or two hours of non-stop projection. While the device is being pitched at everyday users, Olympus aren’t offering any suggestion at launch dates or pricing, but you can check on what the company is willing to share in the (Google-translated) press release below.
