Testing and analyzing method for eye movement

Abstract

The invention discloses a method of and analyzing the eye moving test, which comprises the procedures as follows: selecting test items and method to generate the task list; confirming LED vision stimulating mode and indicating position; vision sampling; analyzing the vision image in real time and outputting original data; judging whether the task sequence is finished, if not yet, returning to position again, while, if finished, stopping the vision sampling; reprocessing and analyzing as well as expressing the data in image shape to form an individual report forms, then stopping the test. The invention can test and analyze automatically the moving of eyeball and output and analyze the original data and the report form in image shape and then provide it to medical staffs for them to analyze and judge the disease on eye. The invention test for the moving of the eye controlled by the micro-processing system automatically, which reduces the working labor for medical staffs.

Description

technical field [0001] The invention relates to the related technical field of medical instruments, in particular, to an eye movement test analysis method used in an eye movement test analyzer. Background technique [0002] In 1975, an eye tracker with a magnetoelectric induction loop as the method of picking up eye movement signals appeared. On the one hand, due to the influence of the physical characteristics of the eyeball movement, the signal is already a signal of an abnormal state; [0003] The infrared reflective eye tracker appeared around 1980, which fundamentally solved the problem of interference with the physical characteristics of eye movements. However, infrared light irradiation cannot be used for long-term detection, and there are also eye movements caused by the influence of light signals. Possibility of changing characteristics.

Problems solved by technology

[0002] In 1975, an eye tracker with a magnetoelectric induction loop as the method of picking up eye movement signals appeared. On the one hand, due to the impact on the physical characteristics of eye movement, the signal is already a signal of an abnormal state;

[0003] The infrared reflective eye tracker appeared around 1980, which fundamentally solved the problem of interference with the physical characteristics of eye movements. However, infrared light irradiation cannot be used for long-term detection, and there are also eye movements caused by the influence of light signals. Possibility of changing characteristics

[0004] In the meantime, there are also designs that use corneal patches to reflect infrared light. The main purpose is to reduce the complexity of image feature signal processing, but there are still problems that irritate the eyes and are difficult for patients to accept psychologically.
