A Baseball Hat That Reads Your Mind
esocid writes to tell us that researchers from Taiwan have created a new baseball cap complete with embedded bio-signal monitoring system. The purpose was to give a neural interface that could be useful in everyday life. "The cap contains five embedded dry electrodes on the wearer's forehead, and one electrode behind the left ear, that acquire EEG signals. Then, the EEG signals are wirelessly transmitted to a data receiver, where they are processed in real-time by a dual-core processor. The BCI system includes Bluetooth transmission for distances of 10m or less (e.g., for driving applications), as well as RF transmission for distances up to 600m (e.g., for potential sports applications). Next, the processed signals are transmitted back to the cap, where the data can be stored, displayed in real-time on a screen, or be used to trigger an audio warning, if necessary."
Why not a propeller-hat? At least that way we have something worth reading.

Well, other than the GIANT ANTENNA sticking out of it and the scotch tape behind the ear.
The EEG obtains information arising largely from the cortex and the summation of millions of neuronal currents. It is inaccurate and not reliable enough for critical applications (any situation where 'backfiring' is a bad thing).
As far as I am aware, the state of art of computer interpretation of EEG is only up to monitoring awareness and sleep and possibly detecting seizures, so this would be good for patients in hospitals & home in diagnosing epilepsy.Might be useful for train drivers or pilots, though, in detecting a sleeper-at-the-wheel.

...it won't be able to penetrate my tinfoil hat.
