Embodiment Construction
[0037] The present invention will be further described below in conjunction with the drawings and specific embodiments.
[0038] An attention training and evaluation device based on force tactile feedback and EEG signal analysis includes force tactile training unit, EEG recording unit and control unit.
[0039] The force tactile training unit is used to send the trainer's finger tactile force data to the control unit.
[0040] The EEG recording unit is used to send the EEG signals of the trainer during the training process to the control unit.
[0041] The control unit includes a training module, an evaluation module, and a control module; the training module is used to store preset and self-designed training programs. The training module includes two-finger, three-finger, and four-finger task types, and the training difficulty increases sequentially. The control module calls the training program and starts training. The evaluation module evaluates the data fed back from the force tac...

The invention discloses an attentiveness training and evaluation device based on force tactile-sensation feedback and electroencephalic signal analysis. The device includes a force tactile-sensation training unit, an electroencephalic recording unit and a control unit. The force tactile-sensation training unit is used to send finger touch force data of a trainee to the control unit. The electroencephalic recording unit is used to send electroencephalic signals of the trainee in a training process to the control unit. The control unit includes a training module, an evaluation module and a control module. The training module is used to store training modes. The evaluation module evaluates data fed back by the force tactile-sensation training unit and the electroencephalic recording unit. Thecontrol module adaptively adjusts training difficulty according to an evaluation result. A physiological index and a behavioral index which characterize an attentiveness level are obtained at the same time, the attentiveness level of the subject can be improved in a short term, an anastomosis degree between the obtained physiological index and behavioral index is very high, and the attentivenesslevel of the trainee can be reliably analyzed and evaluated.
Description
Technical field [0001] The invention belongs to the field of neurocognition, and relates to a device for training attention through force tactile feedback training and simultaneously collecting EEG signals to analyze the brain's working neural mechanism, and specifically is an attention training and evaluation based on force tactile feedback and EEG signal analysis Device. Background technique [0002] At present, the phenomenon of inattention in adolescents is becoming more and more serious. For such phenomena, if the correct guidance and training are not carried out, attention deficit syndrome (ADHD) is likely to occur in the future. At present, there are many methods for attention training, such as video games, meditation training, cognitive experiments, neurofeedback, etc., but they rarely involve tactile channels. At the same time, traditional methods of measuring attention are mostly based on the correct rate and reaction time of behavioral science, and lack the analysis o...
