Problems solved by technology

[0005] At present, although meditation and computer-based games have been developed for attention training, these methods have shortcomings, they may cause mental exhaustion and visual fatigue, or require months of face-to-face teaching by trained experts. There is no targeted research on visual sustained attention, and vision is usually used to receive more than 80% of the information, which makes the research on visual sustained attention more urgent and significant
Furthermore, these current attention trainings often do not provide feedback and the training effects are not quantified

Embodiment 1

[0035] After long-term research, the applicant found that the sensory motor system has neural plasticity, and that tactile training can transfer across channels to improve young people's visual sustained attention. attention.

[0036] According to a preferred embodiment of the present invention, based on the above research findings, a visual sustained attention training device is provided, which is characterized in that it includes earmuffs, eye masks, tactile devices, pressure sensors, finger vibrators, neck vibrators and computer , the trainer puts on the eye mask and earmuffs, repeatedly uses the index finger and / or middle finger of both hands to continuously press the tactile sensor for a predetermined time, and keeps the force within a predetermined range. The vibration of the neck vibrator or the finger vibrator is respectively controlled above the predetermined range.

[0037] According to yet another preferred embodiment of the present invention, a visual sustained at...

Embodiment approach

[0043] According to yet another preferred embodiment of the present invention, the neck vibrator or finger vibrator is used to apply and input tactile signals to the trainer during the vibration process.

[0044] According to another preferred embodiment of the present invention, the visual sustained attention training device transfers and trains visual sustained attention across channels through closed-loop tactile training.

[0045] According to another preferred embodiment of the present invention, the continuous attention response test unit includes a target stimulus test module, a non-target stimulus test module and a probe question test module.

[0046] According to another preferred embodiment of the present invention, the target stimulus test module is used to randomly display numbers 1 to 9 on the computer screen, and collect the tester's keystroke data under the condition that the tester is only pressed when he sees the target number 3 When the non-target stimulus te...

Embodiment 2

[0074] On the basis of Example 1, this example aims to further verify relevant research results.

[0075] According to a preferred embodiment of the present invention, a method for training sustained visual attention is provided. The method is based on pure tactile stimulation and tactile feedback, and can be used to improve the sustained visual attention of young people. Simultaneously, the present invention comprehensively applies behavioral and electrophysiological (128-lead EEG) techniques to quantify the training effect of visual sustained attention. First of all, before training (the first day), design the Sustained Attention Response Test (SART)) and mathematical operation tasks to test the visual sustained attention level of the subjects; secondly, apply the attention training device (system) to the subjects (test or) for a period of 5 days (the second day to the sixth day) of attention training; then, after the training (the seventh day), the subjects were subjected t...

Abstract

The invention relates to a visual continuous attention training and testing system based on electroencephalogram traceability imaging; the system comprises a visual continuous attention training device and a visual continuous attention testing device, and the visual continuous attention training device comprises earmuffs, an eyeshade, a touch device, a pressure sensor, a finger vibrator, a neck vibrator and a computer. A trainer wears the eyeshade and the earmuffs, continuously presses the touch device for predetermined time repeatedly with the index finger and / or the middle finger of the both hands, and maintains the force within a predetermined range. The system can improve the continuous visual attention of the trainee and quantify the training effect.

Description

[0001] This application is a divisional application of a patent with the Chinese patent application number ZL 202011048202.5 and the title of the invention "Visual Sustained Attention Training Device, Training and Testing System and Method", the entirety of which is hereby cited. technical field [0002] The invention belongs to the field of visual sustained attention training, and in particular relates to a visual sustained attention training device, a training and testing system and a method thereof. Background technique [0003] Visual sustained attention is critical for higher-order cognition and real-world activities. Nowadays, the life of young people is full of media multitasking like using mobile phones, computers, etc. Studies have shown that excessive media multitasking will affect people's visual sustained attention function to a certain extent, such as leading to decreased attention control ability, easy distraction, frequent mind-wandering, poor self-satisfactio...
