Wearable electroencephalogram sleeping quality evaluator

Abstract

The invention discloses a wearable electroencephalogram sleeping quality evaluator. 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 sleeping quality evaluation. Audio signals are outputted by an audio interface, and audio simulating signals such as background music and training instructions are provided for sleeping quality evaluation. 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, delta wave components reflecting the sleeping state of the brain are extracted, neural feedback is performed for sleeping quality evaluation, and data are transmitted to a man-machine interaction device through a wireless data interface. Electroencephalograms are used as feedback signals of sleeping quality evaluation, and sleeping quality evaluation efficiency and reliability are greatly improved. By the aid of a wearable computer, many unnecessary interference factors are eliminated, and a training environment is improved.

Description

technical field [0001] The invention belongs to the technical field of psychological biofeedback and relates to a wearable EEG sleep quality evaluation instrument. 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 le...

Problems solved by technology

At present, glasses-type computers sold in the market include products from companies such as Google and Recon, which are mainly used in the entertainment field. The price is high and the supply is small, so it is not convenient for secondary development.
