Researchers at a Japanese university have developed a modern camera that automatically takes pictures of the stuff we find interesting.
The prototype headset, called Neuro-cam, combines a brainwave scanner, which is attached to a smart phone. This allows the device to see what the wearer sees, while a mechanism for calculating brainwaves monitors the user's level of interest through a specially-worn headband. The smart-phone camera is set to automatically record and save five-second scenes that are counted as interesting to the wearer. It has the ability to constantly judge what the user is interested in looking at, on a scale of one to a hundred.
