A brainwave feedback system, adapted to generate feedback based on a user's brainwave, the brainwave feedback system comprises: a brainwave sensing device, configured to obtain a first brainwave signal of the user; a server, storing a keyword string pool including a plurality of sorted keywords, and performing a feedback procedure when a first physiological parameter falls outside of a predetermined parameter range, wherein the first physiological parameter is associated with the first brainwave signal, the feedback procedure includes choosing a keyword from the keyword string pool by the server as a feedback keyword, and outputting the feedback keyword; and an output component, in communicable connection with the server, wherein the output component presents an analysis result corresponding to the first physiological parameter. The present disclosure further discloses an operation method of brainwave feedback system.

Brainwave feedback system and operation method thereof

This invention mainly discloses an EOG-based sleep staging method which is used to improve of an accuracy of automatic sleep judging result. The method may be executed by a processor and comprises steps of reading a to-be-test data having a variation depending on time of EOG generated by a user during a sleep process; acquiring a plurality of eye movement characteristics based on a variation of the EOG of a period, with the characteristics including an eye movement ratio, a blink count, a low frequency power ratio, a high frequency power ratio, an alpha rhythm ratio, a spindle rhythm ratio, a delta rhythm ratio and an average amplitude of eletrooculogram (EOG) signals; and determining a sleep state of the period is a 'WAKE stage', a 'REM stage', a &#x201c;S1 stage&#x201d;, a &#x201c;S2 stage&#x201d;, or a &#x201c;SWS stage&#x201d; based on the EOG characteristics. Furthermore, a computer readable medium with stored programs, and electronic apparatuses are provided.
