Finger vibration tactile stimulus based directing attention measurement system and method

Abstract

The invention discloses a finger vibration tactile stimulus based directing attention measurement system and method. The system comprises a master control module, a slave control module, a vibration tactile module and an anti-interference module. The master control module is connected with the slave control module and capable of controlling the slave control module to stimulate a subject and measure reaction time of the subject. The slave control module is connected with the vibration tactile module and capable of driving the vibration tactile module to generate vibration tactile stimulus in different strength. The vibration tactile module is arranged on fingers of the subject and capable of generating vibration tactile stimulus in different strength to stimulate the fingers of the subject. The anti-interference module is worn by the subject in a measurement process to isolate the subject from sound interference and visual interference of an external environment. The system is capable of measuring a time period from tactile target stimulus generation to feedback generation of the subject and calculating reaction time of the subject to reflect directing attention of the subject, and the problem of difficulty in directing attention measurement under the condition that a visual channel is damaged is solved. In addition, simplicity in operation, convenience in measurement and improvement of measurement efficiency are realized.

Description

technical field [0001] The invention relates to the field of vibration tactile and attention network measurement, in particular to a directional attention measurement system and method based on finger vibration tactile stimulation. Background technique [0002] Attention, explained in terms of the second life morphology, is the ability to pay attention to objective things through the five major information channels of vision, hearing, touch, smell and taste. With people's in-depth research, American scholar M. Posner and others found that the human attention system is divided into three subcomponents: vigilance, orientation and executive control. Among them, orientation is to shift attention to the stimulus that will be selected or focused on. Measuring the orientation effect of attention network can evaluate people's attention and judge whether people's attention is abnormal. Therefore, we can understand the attention of children with ADHD by measuring the orientation eff...

AI Technical Summary

Problems solved by technology

However, if the visual channel of a person is damaged, for example, in the face of a blind person or an elderly person with poor vision, the effect of the human attention network will be measured through the visual channel, and it will be difficult to measure.

[0004] However, at present, there is no use of tactile cues and target stimuli to measure the three effects of the attention network, that is, there is currently a lack of attention measurement systems and methods to measure the orientation effect of the attention network through tactile channels
