People have been experimenting with using brainwaves to control computers for a couple of decades, but now "a team of researchers from Taiwan has designed the new bio-signal monitoring system inside a baseball cap with the goal of making it convenient and easy to use in everyday life," reports Physorg.com.
However, the processing isn't done in the cap: the EEG data is sent to a separate PC via Bluetooth or Wi-Fi.
The researchers from National Chiao-Tung University, National Cheng-Kung University, and the University of California, San Diego, have developed one application: the cap can tell how drowsy you are. This could be useful while driving. Physorg says:
For medical purposes, the researchers suggest that the technology could be used for home care for the elderly, medical monitoring, and exercise training. They also expect it to have applications in controlling household electronics devices, which has previously been investigated for physically disabled individuals.
