Pressing a button is so 20th century. And winking or asking Google Glass to do it for you seems like quite a lot of effort, too. So, for the truly lazy, Neurocam analyzes your brainwaves to work out when you want a picture taking.

Demoed at Japan's Human Sensing 2013 conference, Neurocam uses brainwave sensors that have cropped up in, err, things like cat ears, to gauge your interest on what's happening around you. Judging on a scale of 0 to 100—they don't say exactly how that scale works, sadly—it'll start recording video when the value tops 60. That footage is then turned into a 5-second GIF, reports DigInfo.

Oddly, it uses your iPhone as the basis of its image acquisition power, but teams it up with a headband which includes the brain wave sensor. The camera then faces a prism to allow it to capture images in your line of sight, rather than... the side of your head. It's clearly a rather clunky design, but it's a neat idea—especially if you think of it as proof of concept rather than a mass-market product. How do you feel about your devices responding to your each and every thought? [DigInfo]
