Description

Technical Field

[0001] This invention relates to the field of smart wearable devices, specifically to an anti-seasickness glasses and its optical compensation and adjustment system. Background Technology

[0002] Seasickness, a common form of motion sickness, is essentially a physiological discomfort caused by a perceptual conflict between the vestibular, visual, and proprioceptive systems, severely impacting the experience and mobility of travelers. Physiologically, the vestibular system is responsible for perceiving changes in body position and motion. When a ship is sailing on water, factors such as wind, waves, and currents cause irregular rolling, pitching, and heaving movements, leading to relative displacement of the otolithic membrane and hair cells in the vestibular organs, sending continuously changing motion signals to the brain. Meanwhile, if the visual system observes fixed objects within the cabin, such as seats or walls, it transmits stationary visual signals to the brain. This conflict between the vestibular perception of motion and the visual perception of stillness leads to impaired judgment, resulting in seasickness symptoms such as dizziness, nausea, vomiting, and cold sweats. Furthermore, even when observing external scenes, the ship's movement causes distant reference points such as the sea level and coastline to appear unstable and asynchronous, failing to provide the brain with a clear and stable spatial reference, especially in rough seas, making perceptual conflict difficult to avoid.

[0003] Currently, existing seasickness prevention solutions are mainly divided into three categories. The first category is drug-based seasickness prevention, including oral seasickness medications and topical patches. These solutions alleviate seasickness symptoms by inhibiting nerve conduction in the vestibular system or regulating the balance of neurotransmitters in the central nervous system. However, they have significant side effects, such as drowsiness, dry mouth, blurred vision, and decreased attention, which seriously affect the user's ability to drive, work, and perform other activities. At the same time, the effectiveness of the medication varies from person to person, and some people do not experience good anti-sickness effects. Furthermore, the medication needs to be taken in advance and cannot cope with sudden seasickness, making it unsuitable for long voyages or frequent travel.

[0004] The second category is physical protection solutions, including wearing ordinary goggles, neck supports, and maintaining a fixed posture. Among these, goggles prevent seasickness by blocking visual input, but this prevents users from observing their external environment, affecting navigation safety and ease of movement; neck supports only reduce head movement and cannot fundamentally solve the problem of sensory conflict, so their effect on alleviating moderate to severe seasickness is limited; while maintaining a fixed posture severely restricts the user's freedom of movement, resulting in a poor experience, and is difficult to maintain when the ship is rocking violently.

[0005] The third category is optical anti-nausea solutions, which mainly alleviate perceptual conflict by providing stable visual references. Existing optical anti-nausea products are passive glasses based on polarized or prism lenses, which correct the visual angle by changing the light propagation path. However, the optical parameters of these products are fixed, making them unable to adapt to the dynamic motion of ships under different sea conditions, nor can they be adjusted according to the individual seasickness tolerance of users, resulting in unstable anti-nausea effects. Another category is simple dynamic visual reference devices, such as setting fixed baselines or markers on the lenses. However, the reference markers of these devices are not related to the ship's motion state, and cannot reflect the ship's motion relative to the water surface in real time. It is difficult to form effective coordination between the visual and vestibular recognition positions, resulting in limited anti-nausea effects. Summary of the Invention

[0006] The purpose of this invention is to provide anti-seasickness glasses and their optical compensation and adjustment system to solve the above-mentioned problems. These glasses utilize real-time motion sensing combined with dynamic optical compensation to match the sensory signals of the human vestibular system and visual system, and to collect the three-dimensional rotational angular velocity of the ship. and acceleration of motion It generates an optically compensated image containing a water surface baseline and a ship's trajectory, enabling the wearer's visual system to acquire motion reference information consistent with the vestibular system in real time.

This formula achieves synchronous compensation between the water surface baseline and the navigation trajectory through a unified vestibular sensitivity coefficient.

[0014] Preferably, the optical display module includes a micro-projection mechanism and a semi-transparent mirror. The micro-projection mechanism projects an optically compensated image onto the semi-transparent mirror, which allows external light to pass through while reflecting the optically compensated image, enabling the wearer to observe both the external scene and the optically compensated image simultaneously.

[0015] Preferably, in the optically compensated image, the water surface baseline and the ship's navigation trajectory are in different non-transparent colors, and the background of the optically compensated image is transparent.

This is the ambient light adaptation factor, calculated by the control module based on the light intensity collected by the ambient light detection unit. Its value ranges from 0.7 to 1.0; the stronger the ambient light, the better. The closer it is to 1.0, the less likely the compensated image will be masked under strong light.
