Most of the uses imagined for Google Glass so far are pretty geeky, but video journalist Tim Pool has a different perspective, based on using the device while reporting on protests in Istanbul for Vice magazine. "When there's a wall of police firing plastic bullets at you, and you're running through a wall of tear-gas, having your hands free to cover your face, while saying 'OK Glass, record a video', makes that recording process a lot easier," he says.
