Binocular eye movement acquisition system under high-definition naked eye 3D video stimulation

Abstract

The invention discloses a binocular eye movement acquisition system under high-definition naked eye 3D video stimulation. The system comprises a 3D video imaging module (110), a double-eye movement acquisition module (120) and a circuit control module (130); the 3D video imaging module (110) is used for displaying 3D video stimulation, and meanwhile, the visual field of a tester is limited in a 3Dvideo display area, so that the effectiveness of eye movement data is ensured; the two-eye movement acquisition module (120) is used for synchronously acquiring eye movement data of a tester under 3Dvideo stimulation in a high-precision manner; and the circuit control module (130) is used for controlling a 3D video playing system and eye movement data storage and coding. The system has good watching comfort, can synchronously acquire binocular eye movement data under 3D video stimulation with high precision, is richer in eye movement information, limits the visual field of a viewer while providing naked eye 3D video imaging, guarantees the effectiveness of the eye movement data, is low in cost, and can be applied to related research in the field of eye movement tracking on a large scale.

Description

technical field [0001] The invention relates to the technical field of eye movement instruments, in particular to a binocular eye movement acquisition device stimulated by naked-eye high-definition 3D video. Background technique [0002] An eye tracker (Eye Tracker, ET) is a commonly used instrument in eye movement analysis. The eye tracker usually uses imaging devices such as monitors to present specific image stimuli to the testee, and collects the eye movements of the testee under the observation of the specific image stimulus. dynamic information. Then, the eye tracker uses various indicators to analyze the subjects. Possible test indicators include: fixation, the total attention time of each content in the stimulus image; saccade, the interval time when jumping from one image content to another image content; fixation duration, the continuous fixation time on the area of ​​interest; The tester's local area of ​​interest and the tester's scanning path for the image con...

AI Technical Summary

Problems solved by technology

However, the existing head-mounted AR / VR display device increases the load-bearing of the human head, and the exit pupil distance is very small, which makes the glasses easy to fatigue, and will cause problems such as dizziness and dizziness after use.

In addition, none of the existing eye trackers focus the sight of the subject on the test area, resulting in invalid and redundant collection of binocular eye movement data

[0004] In recent years, home appliances such as players and TVs with 3D stereoscopic display have attracted the attention and investment of major fields and manufacturers around the world. However, the existing 3D stereoscopic display and playback equipment has poor stereoscopic effects and cannot become the mainstream of the market.
