Description

Technical Field

[0001] The invention relates to the field of eye movement recorders, in particular to an eye movement recorder with a wearable anti-falling structure. Background Art

[0002] An eye tracker is an instrument that can capture eye movements and convert them into data signals. It is widely used in many fields such as psychology research, driver monitoring, virtual reality, etc. The core technology of the eye tracker is to study eye movement trajectories by capturing eye movements, and then infer the cognitive process behind the eye movements, such as gaze point, attention distribution, etc.

[0003] Wearable eye trackers are usually integrated into portable devices such as glasses or helmets, and are suitable for research on real-life scene simulations. However, the camera component of a wearable eye tracker is installed on a worn frame, and the shooting angle of the camera component is limited by the frame. Different users have different faces, which results in a fixed camera being unable to accurately capture the eye movement trajectories of different wearers. In addition, the existing eye tracker is worn in a single way, and the camera will shake when the wearer moves, which will affect the capture of the eye movement trajectories.
