Psychological health state eye-movement feedback device

Abstract

The invention provides a psychological health state eye-movement feedback device. The device comprises: a fixing plate, the fixing plate is fixedly mounted on the upper part of a workbench, the fixingplate still includes axle sleeves, first threaded rods, spacing sliding columns, clamping plates and sliding rails. According to the invention, a cranking bar on a right-side driving mechanism is manually rotated to make a first threaded cylinder drive an eye tracker main body to move forward and backward through a sliding seat under the action of threads, then a cranking bar on a left-side driving mechanism is manually rotated to make a second threaded cylinder drive a computer display screen to move forward and backward through a mounting seat under the action of threads, after the adjustment is finished, the rotations of the two driving mechanisms are stopped, and the two driving mechanisms are respectively in threaded connection with the first threaded cylinder and the second threadedcylinder, so that the adjustment of the distance between the eye tracker main body and the computer display screen is more convenient, the accuracy is better, and the reliability of the desktop typeeye tracker during adjustment is improved.

Description

technical field [0001] The invention belongs to the technical field of eye movement feedback devices, and more specifically relates to an eye movement feedback device for mental health status. Background technique [0002] The eye tracker is an important instrument for the basic research of psychology. Eye trackers are used to record the characteristics of eye movement tracks when people process visual information, and are widely used in the research of attention, visual perception, reading and other fields. As early as the 19th century, some people studied human psychological activities by examining human eye movements, and explored the relationship between eye movements and human psychological activities by analyzing recorded eye movement data. The advent of the eye tracker provides psychologists with the use of eye movement technology (eye movement technique) to explore the visual information processing mechanism of people under various conditions, and to observe its dir...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a mental health state eye movement feedback device to solve the following deficiencies in the actual use of the existing desktop eye tracker, such as: 1. The existing desktop eye movement The instrument is mainly divided into three parts: the main body of the eye tracker, the head support mechanism and the computer display screen. The distance between the three parts needs to be adjusted before the desktop eye tracker is used. However, the existing desktop eye tracker In the eye tracker, the main body of the eye tracker and the computer display screen are placed randomly, so it is very inconvenient to adjust, and it has to be adjusted again when it is transported to another workbench; 2. The existing desktop eye tracker Although the head support mechanism in the instrument can support the head, due to the lack of an effective fixed structure, the head of the measured person is easy to swing with the eyes during detection, thereby reducing the feedback quality of the desktop eye tracker The problem
