At first look, this device may look to you as a lab experiment, but its surely the first of many improvements to follow. Called the Neurocam Headset, this cool wearable accessory is developed by a Tokyo-based team. It comes with a head-mounted camera that reads your brainwaves and automatically starts recording when the user experiences an interest in something, of course, using your cellphone camera. What triggers a spike in brain activity depends on the interests the person has. The cell phone camera is notified through an app and the devices camera records a short 5-second video clip of that moment.
