Apart from anything else, the second generation is smaller, 60% lighter and hence more comfortable. Unlike Glass, it allows standard prescription lenses to be fitted. Another key difference is that the glasses need a wired connection to a pocket device to work – a smartphone sized device without a screen but with a touchpad and additional sensors running Android.
It uses fibre projection technology to project an 80” equivalent (at 5 metres), 950 x 540, 3D, stereoscopic, see through image on both lenses of the glasses. A front facing camera and motion sensors do a good job of managing head movement.
Chrome Remote Desktop app allows connection to a desktop IOS, Windows, and Linux computer Wi-Fi. Bluetooth tethering allows an Android or windows phone cellular data connection.
It is definitely not as advanced as Google Glass but at under half Glass’s price that’s to be expected. It has great scope in research, office uses, and personal entertainment – the new H.264 video playback and Dobly sound is supported.
