Problems solved by technology

The subjective evaluation method refers to the evaluation of VIM through subjective questionnaires. The subjects need to answer the questionnaires according to their own experience, and then the researchers conduct statistical analysis on the questionnaires to evaluate the degree of VIM. This method is simple and convenient, but it is highly subjective and low in reliability. The assessment results are not accurate enough
The objective evaluation method refers to the formulaic evaluation of the VIM degree of the subject by defining some objective indicators. This method is not affected by subjective factors, but the selection of indicators is difficult and the test is complicated.

Embodiment Construction

[0014] The present invention will be further described below in conjunction with embodiment.

[0015] The visually induced motion sickness detection method based on the eye movement signal in this embodiment comprises the following steps:

[0016] 1) Wear a head-mounted EEG sensor on the subject's head to detect the number of eye movements in real-time with the eyes open and closed;

[0017] 2) Process the data of the number of eye movements collected by the head-mounted EEG sensor through the formula:

[0018] Calculate the average number of eye movements per minute of the subjects in the two states of eyes open and eyes closed respectively. In the formula, BR is the average number of eye movements per minute, s 1 is the start time of the data segment, s 2 is the end time of the data segment, in seconds, blink(i) is the head-mounted EEG sensor in s 1 -s 2 The eye movement data collected at each sampling moment in the time period, the eye movement signal blink(i) is 1 wh...

Abstract

The invention discloses a view induced motion sickness detecting method based on eye movement signals. The view induced motion sickness detecting method based on eye movement signals comprises the following steps: (1) wearing a heat-mounted brain wave sensor which detects eye movement frequency in an eye opening state and an eye closing state in real time on the head of a testee; (2) processing the eye movement frequency data acquired by the head-mounted brain wave sensor to obtain the average eye movement frequency in every minute in the eye opening state and the eye closing state of the testee; and (3) judging whether the testee is in a motion sickness state or not. According to the view induced motion sickness detecting method based on eye movement signals, whether the testee is in the motion sickness state or not is evaluated by the average eye movement frequency, evaluation is objective and accurate, evaluation operation is simple, and the problem of view induced motion sickness can be reserved conveniently.

Description

technical field [0001] The invention relates to the technical field of visually induced motion sickness state detection, in particular to a visually induced motion sickness detection method based on eye movement signals. Background technique [0002] In recent years, with the rapid development of display technology, more and more people are constantly exposed to new display environments, such as widescreen TVs with high resolution and strong depth contrast, naked-eye 3D TVs, and TVs used in virtual reality and games. Head-mounted display. In addition, with the development of video processing and computer graphics technology, a large number of novel images containing complex and frequent viewpoint motion appear, which cannot be realized by traditional camera technology. With the development and application of these technologies, the image is no longer limited to the plane of the display, but reflects the depth, layering, realism and display distribution of the image, making ...
