Description

Technical Field

[0001] This invention relates to the fields of human-computer interaction technology and computer graphics, and in particular to a system and method for use on mobile devices (such as mobile phones, tablets, VR / AR headsets, and in-vehicle entertainment systems) to alleviate or eliminate kinetosis caused by users consuming any form of screen content (such as watching videos, movies, playing games, reading, etc.) in a moving environment. Background Technology

[0002] Mobile devices have become the primary medium for consuming digital content. An increasingly common scenario is that users spend long periods of time staring at screens while watching videos, playing games, or working while traveling by car, train, or plane. In such scenarios, a serious technological pain point affecting hundreds of millions of users has long remained unresolved: motion sickness.

[0003] The physiological root of motion sickness lies in the "sensory conflict theory": the user's inner ear vestibular system can clearly perceive the acceleration, deceleration, and turning of a vehicle, but the visual system sees a relatively static or mismatched screen image. This conflict between visual and vestibular perception sends contradictory signals to the brain, triggering discomfort symptoms such as nausea and dizziness, severely disrupting the user's viewing and usage experience.

[0004] In existing technologies, some solutions attempt to address this problem, such as adding a fixed "virtual horizon" to the image. However, these solutions have significant drawbacks: 1. Interference with core content: A static and abrupt visual element will continuously occupy screen space, conflict with the content of the video or game itself, distract the user's attention, and destroy the sense of immersion.

[0005] 2. Coarse feedback information: The static reference frame cannot accurately and in real time reflect the dynamic acceleration and deceleration process of the carrier, thus the mitigation effect is limited.

[0006] Therefore, there is an urgent need in this field for a novel technical solution that can effectively synchronize the user's visual and vestibular perceptions and integrate into any screen content in an elegant and seamless manner, thereby fundamentally solving the motion sickness problem in mobile experiences without interfering with the user. Summary of the Invention

[0007] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, overcome the defects of existing solutions for relieving motion sickness such as large visual interference, coarse feedback information and limited effect, and provide a novel, universal motion sickness relief system and method based on dynamic visual metaphor.

[0008] The present invention also provides a system and method for alleviating motion sickness in mobile screen experience as described above, comprising: a motion sensing module configured to: acquire physical motion data of a mobile device in real time via an inertial measurement unit of the mobile device; A data processing module is configured to process the motion data to generate a set of visual effect parameters; The visual rendering module is configured to generate and overlay a non-realistic dynamic visual effect synchronized with the physical motion on the display screen of the mobile device in real time, based on the visual effect parameters.

[0009] According to the present invention, a system and method for alleviating motion sickness in mobile screen experiences are provided, wherein the screen content includes videos, movies, games, or electronic text.

[0010] According to the present invention, a system and method for alleviating motion sickness in mobile screen experiences includes an inertial measurement unit comprising an accelerometer.

[0011] According to the system and method for alleviating motion sickness in mobile screen experiences according to the present invention, the propagation direction of the dynamic visual effect is related to the direction of the physical motion.

[0012] According to the system and method for alleviating motion sickness in mobile screen experiences as described in this invention, the dynamic visual effect is a water ripple, halo, or quicksand effect.

[0013] A method for alleviating motion sickness during mobile screen experiences includes the following steps: S1. The physical motion of the device is sensed in real time through an inertial measurement unit of a mobile device; S2. Convert the physical motion data into a set of parameters for defining a dynamic visual effect; S3. On the display screen of the mobile device, above the main display content, the dynamic visual effect is rendered in real time according to the parameters, so that the features of the dynamic visual effect are synchronized with the features of the physical motion.

[0014] According to the system and method for alleviating motion sickness in mobile screen experiences according to the present invention, the physical motion in S1 is linear acceleration or deceleration.

[0015] According to the system and method for alleviating motion sickness in mobile screen experiences as described in this invention, the rendering of dynamic visual effects in S3 is performed as a post-processing step.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Innovative Solution: This invention abandons the rigid "virtual horizon" model and creatively adopts a "dynamic visual metaphor" (such as water ripples). It provides the user's brain with missing motion signals in an artistic and more intuitive way, cleverly resolving sensory conflict.

[0017] 2. Seamless Immersive Experience: The visual effects can be designed to be very subtle, semi-transparent, and stylized, blending naturally into any screen content without creating strong visual interference like fixed UI elements, thus maximizing the protection of the user's core experience.

[0018] 3. Precise real-time feedback: This system can accurately and in real time convert changes in acceleration in the physical world into changes in the intensity and direction of visual effects, providing richer and more detailed haptic synchronization information than a static reference frame, thus making the mitigation effect more significant.

[0019] 4. Extremely high versatility: As an independent rendering layer, this solution can be easily integrated into any application that requires prolonged screen viewing, including but not limited to video players, cloud gaming platforms, mobile games, e-readers, and VR / AR applications, making it extremely practical and commercially valuable. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments; Figure 1 This is a system architecture diagram of the system for alleviating motion sickness in mobile screen experiences according to the present invention; Figure 2 This is a flowchart of the method for alleviating motion sickness in mobile screen experiences according to the present invention. Detailed Implementation

[0021] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0022] Reference Figure 1 In this embodiment, the system is deployed on a smartphone. The motion sensing module directly calls the interface provided by the operating system (such as the Core Motion framework of iOS or the SensorManager API of Android) to obtain real-time three-dimensional acceleration vector data (ax, ay, az) from the accelerometer at a high frequency (such as 60Hz or higher).

[0023] The data processing module processes the raw data. First, it may use low-pass or Kalman filtering algorithms to filter out noise caused by minor hand tremors, extracting the main acceleration components generated by the vehicle's motion. Next, it maps the processed acceleration vector A to visual effect parameters. For example: • Effect direction: Directly determined by the projection direction of vector A onto the two-dimensional plane of the screen.

[0024] • Effect intensity: determined by the magnitude of vector A (i.e., the magnitude of acceleration).

[0025] • Effects: Can be preset to various art styles, such as water ripples, halos, sandstorms, etc., to match the aesthetic style of different content.

[0026] Visual rendering modules are typically implemented as post-processing effects. After the main content (such as video frames or game scenes) has been rendered, an additional shader pass is rendered. This shader receives parameters calculated by the module and draws dynamic, semi-transparent visual effects in screen space.

[0027] Reference Figure 2 When a user watches a movie in a moving car, the method execution flow is as follows: As the car accelerates, the phone's accelerometer detects forward acceleration. The data processing module recognizes this change and calculates that an upward-flowing, moderately strong ripple should be generated. The visual rendering module immediately renders several upward-flowing, semi-transparent ripples in the lower half of the video frame. Although the user's eyes are focused on the movie content, their peripheral vision can perceive this visual cue consistent with their physical sensations, thus aligning the visual and vestibular signals received by the brain and alleviating motion sickness. When the car returns to a constant speed, the acceleration disappears, and the ripple effect smoothly vanishes as well.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
