Abstract
A device for acknowledging warning indicators includes an electro-encephalograph for detecting signals in the midline occipital region of the user's brain, and a display system for displaying flashing indictors having differing flashing frequencies. The electro-encephalograph detects differing signals caused by the differing flashing frequencies whenever the user observes one of the flashing indicators, and the device thereby recognizes that the user has observed the warning indicator.
