Problems solved by technology

However, the disadvantage of this method is that the results obtained have a greater dependence on the individual psychological benchmarks and preferences of the subjects, so there will be greater individual differences
In addition, this questionnaire method is difficult to achieve real-time measurement of motion sickness level, and this shortcoming makes it difficult to build an automatic VIMS assessment system

Embodiment

[0019] figure 1 It is a flow chart of a specific embodiment of a visually induced motion sickness detection method based on the KC complexity of EEG signals. Such as figure 1 As shown, the visually induced motion sickness detection method based on EEG signal KC complexity of the present invention comprises the following steps:

[0020] S101: collecting EEG signals:

[0021] Set up an EEG signal sensor in the left and right frontal lobe area and left temporal lobe area of ​​the user to collect the EEG signal EEG of the user in the normal stage (without using stereo vision equipment). 0 and detection stage (using stereo vision equipment process) EEG signal EEG 1 , where each EEG signal includes three channels of EEG signals Indicates the EEG signal in the normal stage, i=1 indicates the EEG signal in the detection stage, represent the EEG signals of the user's left frontal lobe area and right frontal lobe area respectively, represent the EEG signals of the user's left t...

Abstract

The invention discloses a visually induced motion sickness detection method based on electroencephalogram signal KC complexity. According to the invention, the left and right frontal areas and the left temporal area of a user are respectively provided with an electroencephalogram signal sensor. The electroencephalogram signal sensors are used for acquiring three channels of brain electrical signals of the user during the normal stage and the detection stage respectively, and then calculating the KC complexity of each electroencephalogram signal. When there is a great difference between detection signals during the normal stage and the detection stage, the visually induced motion sickness phenomenon is judged to occur. Therefore, the detection of the visually induced motion sickness is realized.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic display, and more specifically relates to a detection method for visually induced motion sickness based on KC complexity of electroencephalogram 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 movements have emerged, such as glasses-free 3D mobile phone cases, 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 d...
