Mind Reading Cap Detects Drowsiness, Warns Drivers
Here's a cap that can read your mind. Well almost. It looks like an invention one finds in a Sci-fi novel. When you put it on, the cap detects and analyzes the electroencephalogram (EEG) signals from your brain. Currently it can tell whether a driver is getting too sleepy based on analysing the brain wave patterns.

Taiwanese researchers have designed a new bio-signal monitoring system inside a baseball cap. By measuring EEG signals, the BCI system can monitor an individual’s physiological and cognitive states.
" 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. "
Two types of experiments were conducted. One tested the skills of the drivers in the virtual reality environment. Initially drivers were tested in a virtual reality environment and their response time to the happenings in the road were taken into account. Then they wore the BCI cap, which detected their EEG signals. A comparative analysis of the tests revealed the correlation of the two measurements was 75%.
Researchers suggest that the technology could be used to control home electronics. You don't have to hunt for the remote anymore you can control TVs, computers and air conditioners just by thinking about them.
