Dynamic visual acuity testing system and method

Abstract

The invention provides a dynamic visual acuity testing system. The system can be used for performing dynamic visual acuity testing on movement of a sighting mark in eight directions, and the qualification degree of a driver on a specific task can be truly reflected. The system comprises a sighting mark movement unit, a result feedback unit and a testing data processing unit, wherein the sighting mark movement unit enables a sighting mark to make uniform linear motion on a display screen according to designated directions including upper, right upper, right, right lower, lower, left lower, left and left upper directions, the size of the sighting mark has 1.6-0.1 levels, one level is arranged every 0.1, and only one level size is arranged in each sighting mark living duration, and the sighting mark starts to move according to the sequence from 1.6 level to 0.1 level, and is stopped moving when a signal of the result feedback unit is received; the result feedback unit is used for receiving the judging result of a tested person in the opening direction of the sighting mark, and transmitting the result to the testing data processing unit; the testing data processing unit is used for comparing the judging result of the result feedback unit with the actual opening direction of the sighting mark to provide a comparison result. The invention further provides a method adopting the system.

Description

technical field [0001] The invention belongs to the technical field of visual acuity detection, and in particular relates to a dynamic visual acuity testing system and a testing method. Background technique [0002] Dynamic vision refers to the visual resolution of the observer when there is relative motion between the observed object and the observer. The quality of dynamic vision is closely related to the ability to complete tasks in motion. Therefore, dynamic vision detection plays an important role in checking all kinds of drivers and improving the effect of driver training. At the same time, dynamic vision testing is also an important link in the selection of pilots, which plays an important role in improving pilots' flying performance and combat effectiveness. [0003] In the traditional dynamic visual acuity test system, the movement direction of the visual target is fixed, and it moves from left to right. However, the dynamic visual acuity level of the testee does ...

AI Technical Summary

Problems solved by technology

[0003] In the traditional dynamic visual acuity test system, the movement direction of the visual target is fixed, and it moves from left to right. However, the dynamic visual acuity level of the testee does not respond to the various directions of the visual target movement in the same way. Sensitive to visual target movement in one direction, but slow to respond to visual target movement in other directions
