A prompt, accurate and highly practical drowsiness detecting device and a waking device operatively connected with the same are provided. <??>Drowsiness of a vehicle driver or the like is detected to wake him/her up to prevent the drowsiness from causing an accident. A waveform of blinking is detected by a stress-impedance effect sensor head (1) positioned on a temple bow of a glasses frame in the vicinity of his/her temple, and the drowsiness is determined by a microcomputer (2). Waking him/her up is accomplished by a milligauss AC magnetic field generator (4). <IMAGE> |
