Technical Field

The invention belongs to the technical field of attention training, and particularly relates to an attention training system for automatically adjusting heart rate variability based on virtual reality.

Background

Human cognitive abilities include the ability to orient, perceive, language, compute, memory, and attention. Attention is the basis for all cognitive abilities and is the most critical factor in human learning, work and life. The modern society develops at a high speed, and the attention requirements of various learning and working tasks are gradually improved. For children, only the children with concentrated attention can master more knowledge in the same time or master knowledge more efficiently. If the child is not attentive, a series of consequences can occur, such as: the traditional Chinese medicine is easy to be distracted, lacks concentration on learning tasks, has low efficiency of attending lessons, has low score, is careless and javelin, is dragged during work, and has the defects of more and more lack of confidence, easy dependence on other people and even easy occurrence of irritability and other extreme spleen qi. For adults, the nature of some tasks, such as pilots, drivers, athletes, etc., requires a high degree of attention control to ensure smooth implementation and performance of the task and accuracy of the time. Therefore, the attention ability test is helpful for parents and teachers to know the attention level of children, and to perform intervention and training on children with lower attention level or to perform adaptive education and teaching methods, so that the children are better concerned and the growth of the children is concerned. The attention ability test is helpful for the human resource department to evaluate the competence of employees in the work needing the attention ability, and is helpful for adults to self-evaluate the attention level, effective targeted training is carried out on the basis, the attention can be improved, the cognitive ability is further improved, and the requirement of modern society on the special attention of people is better met.

For example, chinese patent discloses an attention concentration detection apparatus and method based on analysis of heart rate variability [ application No.: CN101658425A ], and a method, device and use for analyzing heart rate variability [ application No.: CN106551691A ], the above two schemes propose to detect and analyze the degree of attention concentration by means of heart rate variability, etc., so as to achieve the attention test, but the above schemes still have some defects:

the comparison file only provides a test scene in a resting state, cannot completely isolate outside visual and auditory noise information, and cannot create a visual and auditory scene related to test/training. However, in the mechanism of information processing, human beings mainly perceive the world by using visual, auditory, tactile, olfactory and other pathways. Where the visual-auditory pathway accepts and perceives information at approximately 94%. Therefore, the visual and auditory sense is the main information processing path of human beings, and related researches of brain science consider that the visual and auditory functions are not independent and the visual and auditory functions of healthy people are mutually connected. The information processing path is divided into visual and auditory single path processing or visual and auditory mixed dual path processing in form. Attention to the information is therefore also primarily reflected in the form of these three audiovisual perception pathways. However, the cognitive function of the human brain is extremely complex, and the human being does not process information in a single task and information in cognitive activities. The external visual and auditory information is extremely easy to influence and interfere with the completion effect of a single cognitive task. Therefore, the external visual and auditory noise information is isolated, and relevant visual and auditory scenes are created and tested, so that the real attention level of the trainer and the importance of the real attention level are reflected.

Furthermore the degree of function and activity of the autonomic nervous system is reflected in heart rate variability. People with abnormal heart rate variability parameters often present or manifest as stress, anxiety, insomnia; or in the case of little interest in anything, slow response, poor concentration and attention. And the 10 seconds is a breathing mode of a breathing cycle, the activation degree of the two sets of systems of the sympathetic nerve and the vagus nerve of the autonomic nervous system can be adjusted, the activation degree of the two sets of systems of the sympathetic nerve and the vagus nerve of the autonomic nervous system can be reflected by the heart rate variability parameter, and the activation degree of the two sets of systems of the sympathetic nerve and the vagus nerve of the autonomic nervous system can represent the attention integration degree of the user. The long-term 10-second breathing exercise can reshape the function of the autonomic nervous system, so that unbalanced sympathetic nerves and vagus nerves tend to be normal and reach balance, thereby reflecting the heart rate variability parameters. I.e. heart rate variability, can be used as a parameter for checking the degree of attention integration and can also be used as a parameter for training the attention effect.

The acquisition positions of the heart rate variability acquisition module 2 include one or more of fingers, wrists, earlobes, and forehead.

Preferably, as shown in fig. 2, the heart rate variability acquisition module 2 here is integrated in the virtual reality headset module 41. Namely, the acquisition position of the heart rate variability acquisition module 2 is the forehead, and the electrocardiosignal is acquired by adopting a photoelectric volume method and heart rate variability data is extracted. In particular, the heart rate variability acquisition module 2 comprises an LED light source 21 of wavelength 500-600 nm and a photoelectric transducer 22. The LED light source 21 with the wavelength of 515nm-580nm is preferred in the embodiment.

The LED light source 21 and the photoelectric converter 22 are both connected to the main control module 8, and the main control module 8 controls the operation of the LED light source 21 and receives the detection data of the photoelectric converter 22.

Specifically, the attention training system for autonomously adjusting heart rate variability based on virtual reality of the embodiment includes the following steps:

s1, wearing a visual and auditory task presentation module 4 on a trainee;

s2, providing a virtual reality scene, and enabling training characters to appear in the visual field of a trainer and/or playing training voice to a trainee in the virtual reality scene;

s3, guiding a trainee to do an attention training task through a virtual reality scene, training characters and/or training voice;

and S4, acquiring heart rate variation data of the trainee in the training process, and meanwhile, carrying out training data analysis on the heart rate variation data and generating a training report.

Further, in step S4, the virtual reality scene, the training characters, and the training speech are transformed according to the heart rate variability data of the trainee so that the attention level corresponding to the heart rate variability data of the trainee is gradually increased. The heart rate variability data as operating parameters for responding to the virtual reality situation task can be used for evaluating the trainee's ability to autonomously adjust heart rate variability in real time. On the other hand, the effect of training the trainee in each task can be evaluated.

And as shown in fig. 4, in step S3, each attention training includes five training tasks, each of which lasts 8-10 minutes, one training lasts about 1 hour, and a relaxation interval of a preset time, such as 2-5 minutes, is given between adjacent tasks. The number of experiments is determined according to the training result, and the attention degree is improved faster and the training frequency is reduced.

The training procedure of this embodiment is described in detail below by way of example:

firstly, enabling a trainee to sit still and wear the virtual reality head-mounted module 41 as required; and then providing a virtual reality scene, enabling the trainee to have training characters in the visual field, and simultaneously playing training voice for the trainee to remind the trainee to enter a state. After training is started, the trainee is guided to perform abdominal respiration in a virtual reality scene, for example, the virtual reality scene is a ship stopped on the shore, the trainee sits on a deck chair, and seawater beats the shore and the ship. The remote sky has a hot air balloon, the slow up and down movement of the hot air balloon represents the breathing period, the time of the balloon moving from top to bottom is 5 seconds, at the moment, the high-fidelity earphone 42 plays 'expiration', and the trainee exhales the air slowly and uniformly as far as possible until the air is completely exhausted. The balloon moves from bottom to top for 5 seconds, at which time the high fidelity earpiece 42 plays the "inhale" and the trainee slowly and evenly inhales as much as possible until it is completely full. Above is an example of a training task, such training task can be multiple, for example 10 or more, so as to avoid that the trainee is too familiar with the training scenario and feels bored.

This embodiment reflects attention level through heart rate variation data, through providing virtual reality scene, provides audio-visual environment simultaneously and trains the testee, and isolated external visual and auditory noise builds the visual and auditory scene relevant with the test, improves the training effect to can reflect the real attention level of training person in training process.
