Description
[0001] The invention relates to the technical field of biological signals, in particular to an EEG acquisition device for concentration recognition. Background technique [0002] For the acquisition of brain concentration, the current mainstream methods are mainly obtained through facial recognition, eye movement recognition, and topic tests. Facial recognition and eye movement recognition want to obtain high-precision identification results, and the cost is very expensive, while the topic test method It is often time-consuming and tedious, and it is very inconvenient to operate. Contents of the invention [0003] In view of the above analysis, the embodiment of the present invention aims to provide an EEG acquisition device for concentration recognition, which is used to solve the problems of cumbersome test steps, long time consumption, high cost of high-precision devices, cumbersome wearing, low recognition accuracy and problems. The problem of poor real-time performance ...
