Strap an iPhone to your head for a window into your mind

Neurocam is an iPhone and EEG headband that automatically records footage of things that interest you. Advertisers would love everyone to wear it.

Google Glass too expensive or unobtrusive for you? How about strapping an iPhone to your head?

That's not quite the idea behind Neurocam, a prototype wearable technology from Japan. But it does involve placing an iPhone next to your scalp.

Many people walk around with smartphones glued to an ear anyway, so radiation be damned. This rig comes with a brain wave scanner and will record what interests you.

Attached to a headband, the iPhone is fitted with a prism so its camera grabs footage from your point of view. Meanwhile, the EEG scans of brain activity correlate spikes in interest with the camera footage.

The tech is similar to that seen in Necomimi, the headband cat ears from Japan that react to your brain waves. Keio University's Yasue Mitsukura helped develop the simple brain wave meter.

A Neurocam iPhone app assigns a value from 1 to 100 for the EEG data and the footage, and when it's over 60, the camera starts recording. The footage goes into an album of 5-second GIFs so you'll be able to remember what piqued your interest.

Of course, most of us can remember what we find interesting, but advertisers would love to get hold of that info. So it's no surprise that Japanese advertising giant Dentsu is backing the Neurocam through a joint venture called Dentsu ScienceJam.

At the recent Human Sensing 2013 in Yokohama, ScienceJam demonstrated the headset and suggested it could be used for all sorts of things.

"Because this system is hands-free, we think it could capture a life log, which would be different from deliberately pressing a shutter to capture things you like," said ScienceJam's Kana Nakano.

"As an application in a B2B environment, Neurocam could determine what goods in stores interest people. And because the information includes position data, you can do mapping, so it could also show what places people are interested in as an aid for urban development planning. We think it could be used in lots of ways like that."
