Abstract

The invention discloses a wearable electroencephalogram waking state detector. A virtual screen is generated at a position which is two meters away from a human eye by a portable projector, and video simulating signals are provided for waking state detection. Audio signals are outputted by an audio interface, and audio simulating signals such as background music and training instructions are provided for waking state detection. Electroencephalogram electrodes are placed at the forehead of a brain by the aid of a rotary adjusting rod and a telescopic adjusting rod. The electroencephalogram electrodes transmit acquired brain wave signals into an embedded processing unit, the embedded processing unit performs spectral analysis for the brain wave signals, theta wave components reflecting the waking state of the brain are extracted, neural feedback is performed for waking state detection, and data are transmitted to a man-machine interaction device through a wireless data interface. Electroencephalograms are used as feedback signals of waking state detection, and waking state detection efficiency and reliability are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of psychological biofeedback, and relates to a wearable EEG awake state detector. Background technique [0002] When the brain nerves are active, there will be weak electric field fluctuations. When tens of thousands of nerves are active at the same time, the electric field will produce rhythmic fluctuations. This fluctuation can be measured from the scalp, which is the brain wave. Brain wave has the following characteristics: it is a bioelectrical signal spontaneously generated by the central nervous system; it is a random signal with non-stationary and non-Gaussian characteristics; it can reflect the state and changes of the nervous system. Therefore, collecting brain waves can monitor people's physiological and psychological states through analysis. [0003] Non-invasive EEG acquisition technology is relatively complicated, because the collected signal is a small signal at the microvolt level, which is ...
