In Japan, product designers have created the Neurocam, a "working prototype" that uses their own EEG signals to record animated GIFs via an iPhone strapped to the side of your head (yes, it looks stranger than Google Glass).

On being asked if this was real and not a hoax, a representative said of the Neurocam: "We're using the iPhone so that both the analysis and video recording can be done on a single device. This is still a concept model so there is a possibility to turn this into a wearable camera."

The device uses a headband to sense your brain's electrical activity through the scalp. Then an attached iPhone uses an algorithm to parse the electrical signals for signs of "interest" about something in your visual field. If this interest-signal passes a certain threshold, the Neurocam triggers the iPhone to record a five-second GIF video clip--capturing whatever it was that caught your eye, without you having to lift a finger (or even consciously think about it).

However, the most interesting thing about the Neurocam isn't the automagical photo-taking capabilities, but its experimental configuration - the fact that the iPhone acts as a window into your mind.

If the project materializes, it could raise plenty of privacy-violating concerns. Imagine the things going through your mind being projected on a screen for everyone to see, or being hacked into even. Of course if the Neurocam ever goes mainstream, it'll be redesigned into something safer for use.
