Vision and touch tester and visual and tactual sensitivity testing method

Abstract

The invention discloses a vision and touch tester and a vision and touch sensitivity testing method. In the vision and touch tester, a parameter testing module of a parameter setting and signal generating module is respectively connected with the input end of a stimulating signal receiving module; the output end of the stimulating signal receiving module is connected with the input end of a signal control module; the output end of the signal control module is connected with the input end of a multi-channel multi-path signal generation module; the output end of the multi-channel multi-path signal generation module is respectively connected with a vision signal source and a touch signal source; a 'yes' button and a 'no' button are respectively connected with the input end of a feedback signal acquisition module; the output end of the feedback signal acquisition module is connected with the input end of a feedback signal sending module; and the output end of the feedback signal sending module is connected with a data processing module. Besides conventional vision, touch and double-channel combined tests, the invention also can realize the researches of touch alarms, sports touches, touch memories, vision and touch combined motion perception phenomena, and the like.

Description

technical field [0001] The invention relates to a testing device and testing method for visual and tactile sensitivity testing of the human body using embedded technology, in particular to a two-channel portable physiological and psychological testing device and testing method thereof, belonging to psychological and behavioral measurement, human-computer interaction and physiological testing and other technical fields. Background technique [0002] In the information obtained from the outside world, vision is dominant, followed by hearing, but touch is also extremely important. People know objective things through the interaction and coordinated activities of various senses. In the current research on physiology, psychology, human-computer interaction and intelligent robots, the research results of vision are the most abundant and prominent, followed by hearing, and touch and other senses are few and far between. In traditional interaction methods, vision and hearing have ...

AI Technical Summary

Problems solved by technology

The instrument has the following defects: it is difficult to achieve accurate measurement; non-automated procedures lead to clumsy manual operation; the time accuracy and spatial resolution accuracy are too low to meet the high-precision, digital and automated testing requirements

However, the existing technology generally has shortcomings such as single stimulus type, limited test conditions and methods, strong professionalism, fixed and non-adjustable stimulus intensity and frequency, especially the inability to accurately match and integrate the two sensory channels of vision and touch.
