Android App displays brain waves via wireless headband

Here’s an experimental app that can measure your brain waves. This wireless device embraces the head, clips onto an earlobe, and measures neural activity and pulse. The results are sent to an gaming app installed on an Android smartphone, which displays graphs and info about the state of the brain during a 30-second test…

While that device was pretty much a parlor game, this conceptual device, designed by KDDI R&D Laboratories, looks to be more sophisticated. According to Japan Trends, the device was introduced this week at the International Modern Hospital Show in Tokyo, and is more of a biofeedback system, appearing to take portable brainwave measurement to the next level.

The signal from its headband is received on an Android smartphone, where the test subject plays one of three different games for 30 seconds. Then, the app displays a chart that graphs concentration and meditation, otherwise known as “focused state” and “relaxed state.” The app also works without a game, where the test subject thinks about various emotional topics for 30 seconds, and then measures the result.

The device is not available for sale yet. So far, it’s in the concept and research stage. Could this be the precursor to portable lie detectors? Perhaps it could be used for market research, measuring people’s reactions to various advertisements or products. Maybe it could be used to gauge the interest level of a tech article on the web.
