In this paper, a portable or wearable online monitoring system for eye movement and head motion parameters is designed. The eye movement tracking and head tracking are used to monitor the wearer for a long time, so as to determine the function expectation of the wearer in real time, and the lack of awakening condition under the setting conditions. In order to improve the level of arousal, people used sound, light and vibration stimulation to conduct state warning and physical stimulation. From the system, the wearer’s brain fatigue state data can be monitored in a long time and continuous monitoring in the process of continuous operation and sleep deprivation, which can effectively improve the user’s long time working ability and working state, and improve the vigilance and operation ability.

Introduction

The activity of the cerebral cortex will also change, which is characterized by reduced thinking activity, reduced thinking agility and so on. The decline and lack of awakening not only reduces the ability of people’s work, reduces production efficiency, and is easily distracted, lacks accuracy, errors, accidents, and arousal. There is a close connection between state and safe production. In the daily work, many jobs need a long time to maintain a higher vigilance, such as airport dispatchers, car drivers, medical workers, aerospace pilots, and military personnel carrying out special tasks. If such operators are mismanaged due to the drop-in vigilance, they may cause huge casualties and property losses. Therefore, how to detect fatigue quickly has become a very important research topic in the field of brain cognition. At present, the methods of brain fatigue detection at home and abroad are mainly divided into two kinds of subjective detection and objective detection, of which the objective detection mainly includes the behavior feature detection (such as blinking, head action, mouth movement, etc.) and physiological characteristics detection (such as EEG, eye power, EMG, etc.); Subjective testing mainly includes evaluative detection and physiological response detection Physical reaction detection. The awakening methods mainly include physical regulation, chemical regulation and biological regulation.
