The El-10 can be mounted on all sorts of glasses, from regular to the protective working kind. It has a tiny 640 x 400 OLED display that, much like Google Glass, sits semi-transparently in the corner of your vision when you wear the product on your face. A small forward-facing camera can capture photos and videos, or even beam footage back to a supervisor in real time. The El-10 runs Android 4.2.2 Jelly Bean and comes with only a bare-bones operating system, as Olympus is pushing the ability to customize it

It’s really cool that it can be mounted on any pair of glasses. Olympus provides clips of various sizes to adjust to multiple frames. It weights 66g.

The manual mentions multiple built-in apps: image and video players, a camera (1280x720px), a video recorder (20fps, up to 30min recording), and the QR scanner. It connects to other things via Bluetooth or wireless network.
