Embodiment

[0055] A kind of continuous attention control system of the joint feedback of EEG and finger pressure of the present embodiment, such as figure 1As shown, it includes sequentially connected finger pressure measurement module 1, finger pressure sampling transmission module 2 and finger pressure conversion recording module 3; sequentially connected EEG acquisition module 4, EEG storage module 5 and EEG data analysis module 6; Both the pressure conversion module 3 and the EEG data analysis module 6 are connected with the joint feedback presentation module 7 .

[0056] The finger pressure measurement module 1 detects the finger pressure data of the subject. The finger pressure measurement module 1 includes at least one pinching board, a housing, a laser transmitter and a light receiving board. One end of the pinch board is exposed outside one side of the shell, the laser emitter is set on the other end of the pinch plate, and the laser emitter is set inside the shell; the light r...

Embodiment 2

[0075] The EEG feature selection unit 72 automatically sets the EEG characteristic information feedback according to the finger pressure frequency amplitude feature of the subject, and the formula of the finger pressure frequency amplitude feature fAFF is as follows:

[0076]

[0077] Among them, ω is frequency; T is time; F represents Fourier transform; n is the number of frequency points in the current frequency band; m is the number of frequency points in the total frequency band;

[0078] When the fAFF on the finger pressure 12-16Hz frequency band is higher than 0.3, the power of the beta wave is automatically set as the EEG characteristic feedback signal; when the fAFF on the finger pressure 4-8Hz frequency band is higher than 0.3, the power of the theta wave is automatically set to EEG feature feedback signal; in other cases, the ratio of Theta wave to Beta wave power is automatically used as the EEG feature feedback signal.

[0079] The scheme of this embodiment can ...

Abstract

The invention discloses an electroencephalogram and finger pressure combined feedback continuous attention regulation and control system. The problem that a testee with electroencephalogram feedback is difficult to enter a continuous attention state without a task is solved. The system comprises a finger pressure measurement module, a finger pressure sampling transmission module and a finger pressure conversion recording module which are connected in sequence, and an electroencephalogram acquisition module used for acquiring electroencephalogram analog signals of the testee; an electroencephalogram storage module used for converting the acquired electroencephalogram analog signals into digital signals and storing the digital signals; an electroencephalogram data analysis module used for completing analysis and extraction of electroencephalogram characteristic signals according to the acquired electroencephalogram signals; and a combined feedback presentation module used for carrying out visual graphic presentation on the electroencephalogram characteristic signals and the finger pressure signals. An electroencephalogram and finger pressure combined feedback mode is adopted, a testee can quickly enter and keep a continuous attention state, and the continuous attention state of the testee can be accurately evaluated.

Description

technical field [0001] The invention relates to the field of a continuous attention control system, in particular to a continuous attention control system with combined feedback of brain electricity and finger pressure. Background technique [0002] EEG feedback refers to extracting EEG characteristic signals and feeding them back to the subjects through visual images. The subjects adjust the EEG signals through certain strategies to train certain cognitive functions. This technique is widely used in continuous attention training and intervention and treatment of attention deficit-related diseases. [0003] In practical applications, most of the EEG feedback techniques adopt the unspecified task feedback regulation mode, which means that the subjects self-regulate according to the feedback EEG characteristic signals. For example, a "brain function activity detection and regulation combined method, device and system" disclosed in Chinese patent literature, its announcement n...
