摘要：
A system and a method for preventing drowsiness are provided. The system for preventing drowsiness calculates brainwaves of a user by receiving a signal around a head of a user without contact, detects a state of the user based on the calculated brainwaves, and performs a necessary function according to the detected state of the user. Thus, convenience is increased when measuring the brainwaves of the driver using the contactless electrodes.
