Mirama wants do away with the the camera button on your smartphone. In fact, don't even get the smartphone out to begin with. Its prototype headset lets you frame and take a picture using your hands and its built-in camera. No buttons, no vocal cues, not even a wink. Other gestures, registered by the camera sensor, add the ability to confirm or cancel (thumbs up and down, respectively) while you can even attempt a hand-written message ... if you have the right level of motor control. (Our own gestured penmanship during a quick demo proved we didn't.) The cameras on the left and right, meanwhile, offer a constant stream of what you'd be looking at if you weren't wearing the headset. Gestures (well, your hands) then appear in bright cyan on top of the video feed.
