Description

Technical Field

[0001] The embodiments of the present invention relate to the field of display control technology, and in particular to a control method, device, equipment and storage medium for alleviating motion sickness. Background Art

[0002] Motion sickness is a common problem for many people when riding in a car. This phenomenon is closely related to physiological factors such as the human vestibular system and visual system. At present, although there are some methods to relieve motion sickness, most of them are based on traditional drugs or simple adjustments to riding habits. With the widespread use of mobile devices (such as mobile phones) during riding, motion sickness may be aggravated by improper viewing of visual content. At the same time, existing technologies lack an effective means to accurately assess individual physiological states (such as eye fatigue and vestibular nerve status) and provide personalized visual feedback based on this to alleviate motion sickness symptoms.

[0003] Nowadays, existing mobile phone manufacturers (APPLE iPhone) have proposed a mechanism for following the animation points on the display based on the mobile phone hardware detection of the motion state - vehicle motion prompt. After this function is turned on, when the mobile phone detects that you are in a moving vehicle, animation points will be displayed on the edge of the screen. These small dots will move with the changes in the movement of the vehicle, representing the direction of vestibular movement (opposite to the direction of vehicle movement). In this way, it can help reduce sensory conflicts and make your eyes and body perception more unified, thereby reducing the discomfort caused by looking at the phone to a certain extent and relieving motion sickness symptoms. However, it is difficult to comprehensively consider the passenger's own situation based on the way the hardware detects the direction of movement.

[0048] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined and referenced with each other under the premise of no contradiction.

[0049] In order to facilitate understanding of the embodiments of the present application, the following content is first introduced regarding motion sickness caused by looking at mobile phones while riding in a car.

[0050] Motion sickness is a common problem for many people when riding in a car. This phenomenon is closely related to physiological factors such as the human vestibular system and visual system. At present, although there are some methods to relieve motion sickness, most of them are based on traditional drugs or simple adjustments to riding habits. With the widespread use of mobile devices (such as mobile phones) during riding, motion sickness may be aggravated by improper viewing of visual content. At the same time, existing technologies lack an effective means to accurately assess individual physiological states (such as eye fatigue and vestibular nerve status) and provide personalized visual feedback based on this to alleviate motion sickness symptoms.

[0051] Nowadays, existing mobile phone manufacturers (APPLE iPhone) have proposed a mechanism for following the animation points on the display based on the mobile phone hardware detection of the motion state - vehicle motion prompt. After this function is turned on, when the mobile phone detects that you are in a moving vehicle, animation points will be displayed on the edge of the screen. These small dots will move with the changes in the movement of the vehicle, representing the direction of vestibular movement (opposite to the direction of vehicle movement). In this way, it can help reduce sensory conflicts and make your eyes and body perception more unified, thereby reducing the discomfort caused by looking at the phone to a certain extent and relieving motion sickness symptoms. However, it is difficult to comprehensively consider the passenger's own situation based on the way the hardware detects the direction of movement. The passengers' own physiological factors are different, and the universality of this mechanism is difficult to get a good experience.

[0052] In order to solve the above-mentioned technical problem of difficulty in accurately assessing whether a passenger is motion sickness, the present invention proposes a control method for alleviating motion sickness. The implementation details of the control method for alleviating motion sickness of this embodiment are specifically described below. The following content is only the implementation details provided for easy understanding and is not necessary for implementing this solution.

[0053] Embodiment 1:

[0054] The control method for alleviating motion sickness of this embodiment can be applied to electronic devices with communication, computing and data storage capabilities. The specific process can be as follows: Figure 1 As shown, steps 101-103 are included, specifically including:

[0055] Step 101: monitor passengers in a vehicle and obtain physiological data of the passengers.

[0056] Specifically, the execution subject of the control method provided in this embodiment may be a control device or a display device, and a sensor for collecting physiological data of a passenger is installed on the control device or the display device, so that the physiological data of the passenger can be directly collected when the passenger uses the corresponding control device or the display device. Among them, the control device or the display device is an in-vehicle device.

[0057] Furthermore, in the present embodiment, the passenger is a passenger using a display device in a vehicle. By monitoring the process of the passenger using the display device, physiological data can be monitored in real time, thereby facilitating real-time adjustment of display parameters of the display device through the control method provided in the present embodiment, and providing display control for alleviating motion sickness in combination with the physiological data of the corresponding passenger, thereby achieving personalized adjustments for physiological changes of different display devices and improving the riding experience of different passengers.

[0058] In some examples, the display device is a vehicle-mounted display screen or a mobile display terminal. The mobile display terminal includes portable display devices such as mobile phones, tablet computers, and laptop computers.

[0059] In some embodiments, the prerequisite for starting step 101 is to identify that the passenger is in a sports environment. In this embodiment, a horizontal detector is installed on the display device to monitor whether the display device is in a sports environment, and then the application or device corresponding to the control method provided in this embodiment is turned on when it is in a sports environment, and then each sensor in the physiological data acquisition module is automatically collected and initialized.

[0060] Step 102: Analyze the passenger's current motion sickness risk level based on the physiological data.

[0061] Specifically, physiological data usually has normal state values, but motion sickness will cause the physiological data to fluctuate. The degree of change in physiological data of different passengers varies. Some passengers are not prone to motion sickness, which leads to smaller fluctuations in their physiological data when using display devices on the bus. Some passengers are prone to motion sickness, which leads to larger fluctuations in their physiological data when using display devices on the bus. Therefore, by setting different motion sickness risk levels, the current motion sickness risk level of the passenger can be analyzed based on the passenger's physiological data, and the passenger's degree of motion sickness can be accurately assessed, so as to provide adaptive display adjustments based on the degree of motion sickness and improve passenger comfort.

[0062] In some examples, the motion sickness risk level includes at least two levels. In this embodiment, the motion sickness risk level is set to four levels from low to high, namely the first level, the second level, the third level and the fourth level. Among them, the first level is a light risk, and no display adjustment is required. The second level is a medium risk, and adaptive display adjustment needs to be provided. The third level is a medium-high risk, and a greater degree of display adjustment needs to be provided. The fourth level is a high risk, and it is necessary to prompt passengers to pause watching and / or turn off the display device. Through the setting of multiple levels, it is possible to cover a variety of motion sickness levels, effectively alleviate the risk of motion sickness of users when riding, improve the experience of users using display devices when riding, and facilitate adaptive adjustments for customers with different motion sickness tolerance.

[0063] Step 103: Match a motion sickness adjustment strategy corresponding to the motion sickness risk level from a preset motion sickness adjustment strategy library according to the motion sickness risk level, and use the motion sickness adjustment strategy to adjust display parameters of the target display device in the vehicle.

[0064] Specifically, a plurality of motion sickness adjustment strategies are configured in the motion sickness adjustment strategy library. Different motion sickness adjustment strategies are adapted to different motion sickness risk levels. This facilitates the direct and quick matching of the corresponding motion sickness adjustment strategy after determining the current passenger's motion sickness risk level. There is no need to perform tedious analysis and processing. The display parameters of the target display device in the vehicle can be adjusted directly through the quickly matched motion sickness adjustment strategy, thereby improving the response speed and facilitating the adaptive adjustment of the display parameters according to the passenger's physiological data in real time, thereby promptly alleviating the passenger's motion sickness and improving the passenger's comfort in using the display device.

[0065] Among them, the level of motion sickness risk corresponds to the number of motion sickness adjustment strategies, which is convenient for providing adaptive adjustment strategies for different motion sickness risk levels and accurately adjusting according to the degree of motion sickness of the passengers.

[0066] In this embodiment, by collecting the physiological data of the passenger, it is possible to accurately process and analyze the current passenger's real-time motion sickness level from the physiological data, thereby determining the motion sickness risk level, and adjusting the display parameters of the display device currently used by the passenger in the vehicle by matching the motion sickness risk level with an adaptive motion sickness adjustment strategy. This can not only accurately judge the passenger's motion sickness risk, but also accurately provide display adjustments to alleviate motion sickness symptoms, thereby improving the comfort of passengers using display devices while riding in a vehicle.

[0067] In some embodiments, the physiological data includes eye physiological data and / or hearing test data, wherein the eye physiological data includes at least one of pupil diameter size, eye closure frequency, and eyeball position data;

[0068] Specifically, changes in pupil size and eye closure frequency in the eye physiological data can intuitively reflect the passenger's eye fatigue state. The eye position data is the position of the eye relative to the center of the eye under normal eye use and normal head posture. It is convenient to judge whether the eye position is abnormal based on the eye position data, and then judge the passenger's visual fatigue or visual function abnormality. The passenger's motion sickness state can be accurately identified in combination with the degree of eye fatigue and the visual function state. Through the combined evaluation of multiple eye physiological data, the user's motion sickness risk can be more accurately judged, and the display parameters of the display device can be more accurately adjusted based on visual judgment to provide visual stimulation adapted to the passenger's current needs and more directly and accurately alleviate motion sickness symptoms.

[0069] Furthermore, the hearing test data is data that needs to be interacted with by the passenger. Generally speaking, the hearing-related test content can be played to the passenger using headphones or speakers, so that the passenger's hearing test data can be determined based on the passenger's answers to the hearing-related test content. Based on the association between vestibular nerve disorders and hearing abnormalities in medical research, it is possible to determine whether the passenger's vestibular nerve is abnormal through the passenger's hearing test data, and based on the vestibular nerve status, the passenger's motion sickness level can be more accurately assessed, thereby improving the accuracy of identifying the passenger's motion sickness level.

[0070] In some examples, when hearing test data is combined with eye physiological data as physiological data to evaluate the passenger's motion sickness risk level, the passenger's motion sickness risk level is first roughly analyzed in real time through the eye physiological data. When the eye physiological data analyzes that the passenger's motion sickness risk level reaches a certain level, the hearing test function can be activated. The hearing test function is used to collect hearing test data from the passenger, and then the passenger's vestibular nerve is further accurately and meticulously combined to accurately analyze the passenger's motion sickness risk level, so as to provide corresponding display parameter adjustments more accurately, thereby improving the accuracy and effectiveness of alleviating motion sickness.

[0071] In some examples, when collecting eye physiological data, pupil diameter, eye closure frequency, and eye position data are also collected at the same time, so as to use multiple physiological data to comprehensively assess the risk of motion sickness and improve the accuracy of motion sickness risk assessment.

[0072] In some embodiments, the passengers in the vehicle are monitored to obtain physiological data of the passengers, such as Figure 2 As shown, including:

[0073] Step 1011: using an image acquisition sensor and / or an optical sensor to collect eye physiological data of the passenger; and / or,

[0074] Step 1012: Use the hearing test module to send a hearing test signal to the passenger, receive the passenger's response content, and obtain the passenger's hearing test data according to the passenger's response content.

[0075] Specifically, the image acquisition sensor, optical sensor and hearing test module are directly placed on the control device or display device corresponding to the control method, so that passengers can collect physiological data in real time while using the display device, thereby improving the real-time performance and accuracy of data collection.

[0076] In some examples, the image acquisition sensor is a high-precision camera and the optical sensor is a miniature infrared sensor, which can non-invasively collect the pupil diameter size, eye closure frequency and eye position data of the passenger's eyes.

[0077] In some embodiments, during the hearing test, sound signals of different frequencies and intensities are played to the passengers so that the passengers provide different feedback responses, thereby collecting the hearing test data of the passengers.

[0078] In some examples, earphones that can sense hearing can be used for passengers to wear, so that when the passenger uses the earphones to play the audio of the display device, the earphones can identify and record the response data of each ear of the passenger, thereby obtaining the passenger's hearing test data. When earphones with hearing test functions are used by passengers, it is possible to determine whether the passenger's hearing test data is abnormal by sensing the hearing changes of the left and right ears in real time.

[0079] In some examples, for scenarios where headphones are not used, the test can be performed by periodically playing sound signals of different frequencies and intensities to passengers through speakers. When the passengers are able to hear the sound and respond (such as pressing a touch button or saying "I heard it", or touching / tapping the display device, or nodding), the frequency and intensity values ​​when the user first hears the sound are recorded. Other frequencies are then tested in order of increasing frequency, such as 500Hz, 1000Hz, 2000Hz, 4000Hz, 8000Hz, etc., and the above intensity adjustment and response recording process is repeated. In the absence of headphones, the hearing test can be performed directly through the display device or the speaker device in the vehicle, thereby achieving the effect of accuracy and convenience in collecting hearing test data.

[0080] In some embodiments, when the physiological data of the passenger is obtained, the physiological data includes at least two items of physiological data, such as Figure 3 As shown, the control method also includes:

[0081] Step 201: preset target weight values ​​of the effects of various physiological data on motion sickness, and generate a weight model for calculating a motion sickness risk coefficient based on the target weight values.

[0082] In some embodiments, step 201, such as Figure 4 As shown, including:

[0083] Step 211: determining an initial weight value of the effect of each physiological data on motion sickness based on the corresponding coefficients of each physiological data and the preset motion sickness risk;

[0084] Step 2012: In response to the passenger's adjustment parameters for the corresponding coefficients of various physiological data and the motion sickness risk, the initial weight value is adjusted according to the adjustment parameters to obtain the target weight value.

[0085] In this embodiment, the passenger can actively input the adjustment parameters of the corresponding coefficients of various physiological data and the motion sickness risk according to his / her understanding of his / her motion sickness condition, so that the target weight value can be generated after adjustment based on the system default initial weight value, so as to use the target weight value that fits the passenger to evaluate the motion sickness risk and improve the accuracy of motion sickness risk evaluation. Among them, when the passenger does not make any adjustment, the adjustment parameters of the corresponding coefficients of various physiological data and the motion sickness risk of the current passenger can be determined to be 0, that is, no adjustment is made, so that the initial weight value is directly determined as the target weight value for motion sickness risk evaluation, which is conducive to direct use experience for passengers who do not understand their own motion sickness condition, and improves the applicability of the method and the flexibility of the use process.

[0086] Further, by presetting a weight model, it is convenient to analyze the current motion sickness risk level of the passenger. Specifically, the step of analyzing the current motion sickness risk level of the passenger based on the physiological data includes steps 202-204, such as Figure 3 As shown, specifically including:

[0087] Step 202: Compare each of the physiological data with its corresponding normal threshold value, and determine each comparison result corresponding to each of the physiological data;

[0088] Specifically, by comparing the physiological data with its corresponding normal threshold, that is, performing difference processing between the two, the phase difference value between the two is obtained, so that the motion sickness risk factor can be evaluated by using the phase difference value as a comparison result, thereby improving the accuracy of evaluating the motion sickness risk.

[0089] Step 203: Input each comparison result into the weight model for calculation to determine the current motion sickness risk coefficient of the passenger;

[0090] In some embodiments, step 203, such as Figure 5 As shown, including:

[0091] Step 2031, respectively multiplying each comparison result with the target weight value of the physiological data corresponding thereto, to obtain respective multiplication results corresponding to each physiological data;

[0092] Step 2032: sum each of the product results to obtain a sum result, and determine the current motion sickness risk coefficient of the passenger through the sum result.

[0093] Specifically, the difference between the pupil diameter and the normal value is recorded as LOF1, the difference between the eye closure frequency and the normal value is recorded as LOF2, the difference between the eye position data and the normal value is recorded as LOF3, and the difference between the hearing test data and the normal value is recorded as LOF4. Therefore, the target weight value of the abnormal pupil diameter is recorded as w1, the target weight value of the eye closure frequency is recorded as w2, the target weight value of the eye position data is recorded as w3, and the target weight value of the hearing test data is recorded as w4. Therefore, the formula for calculating the motion sickness risk coefficient is as follows:

[0094] Motion sickness risk factor = w1×LOF1+w2×LOF2+w3×LOF3+w4×LOF4;

[0095] Based on this, the motion sickness risk coefficient can be quickly calculated by combining multiple physiological data, thereby improving the accuracy of motion sickness risk assessment.

[0096] Step 204: Determine the passenger's current motion sickness risk level according to the motion sickness risk coefficient.

[0097] Specifically, each physiological data has a normal threshold range. When it exceeds the normal threshold range, it means that the corresponding physiological data is abnormal, and the passenger's motion sickness risk coefficient can be analyzed, and then the passenger's motion sickness risk level can be accurately assessed through the motion sickness risk coefficient, thereby improving the accuracy of motion sickness risk identification.

[0098] Furthermore, because the normal physiological data of different passengers may differ, the system can pre-store normal physiological data and normal thresholds of various physiological data of each frequently used passenger and the corresponding identity information, and match the identity information in the system by identifying the current passenger's identity information. When the passenger is a passenger whose identity information is recorded in the system, the normal physiological data of the current passenger can be quickly obtained, and then it is convenient to compare according to the changes in the physiological data monitored by the current passenger, thereby improving the accuracy of assessing the motion sickness risk of different passengers; when the passenger's identity information is not recorded in the system, the normal physiological data can be used for comparison, and the motion sickness risk of the passenger can also be assessed, thereby improving applicability. Generally speaking, normal physiological data is the average data of humans, and there is only a partial difference from the normal threshold of the actual physiological data of different passengers, which does not affect the accuracy of the actual assessment of motion sickness risk.

[0099] In some examples, when the physiological data includes pupil diameter, the obtained pupil diameter is compared with a preset normal pupil size range (the pupil size range under normal rest and eye use). If the pupil diameter is smaller than the lower limit of the normal range (2.5-4 mm) or larger than the upper limit of the normal range and lasts for a certain period of time, it is determined to be a pupil abnormality related to eye fatigue.

[0100] When the physiological data includes eye closure frequency data, when the eye closure frequency per unit time is higher than a certain proportion of the normal blinking frequency (the normal blinking frequency is 10-15 times per minute), when it is higher than 15 times and lasts for a period of time, it is judged as a frequent eye closure state related to eye fatigue.

[0101] When the physiological data includes eye position data, such as Figure 6 As shown, it is compared with the normal eye position range (based on the eye position data range under normal eye use and head posture). If the eye position deviation in the up-down and left-right directions exceeds a certain threshold (for example, the up-down deviation exceeds 2 mm, and the left-right deviation exceeds 3 mm) or the relative position relationship between the two eyes is abnormal (such as the strabismus angle exceeds the normal range), it is determined that the eye position abnormality is related to visual fatigue or visual function abnormality.

[0102] When the physiological data includes hearing test data, it is compared with the standard hearing value range (0-25 decibels is the normal hearing range). If the hearing test value deviates significantly from the standard range at certain frequencies, combined with the association between vestibular nerve disorders and hearing abnormalities in medical research, it is determined whether the vestibular nerve is disordered.

[0103] In some examples, different motion sickness risk levels are configured with different ranges of motion sickness risk coefficient values. The corresponding motion sickness risk level is matched by determining the range within which the motion sickness risk coefficient value falls, thereby providing a certain amount of change in the range of the motion sickness risk coefficient value, ensuring that the motion sickness risk level is switched only after a certain period of change, thereby avoiding the adverse experience caused by high-frequency real-time adjustment of the display device.

[0104] Specifically, in this embodiment, there are four levels of motion sickness risk from high to low, namely level 1, level 2, level 3 and level 4, where the motion sickness risk coefficient range corresponding to level 1 is 0-30%; the motion sickness risk coefficient range corresponding to level 2 is 30%-60%; the motion sickness risk coefficient range corresponding to level 3 is above 60%, the motion sickness risk coefficient range corresponding to level 4 is above 90%, or the motion sickness risk coefficient increases too fast per unit time (such as exceeding 20%).

[0105] Furthermore, when the motion sickness risk level is the maximum level, that is, the motion sickness risk level is the fourth level, the corresponding motion sickness adjustment strategy includes generating a prompt signal for reminding the passenger to stop watching the display device and / or forcing the display device to be turned off, so as to alleviate the motion sickness reaction caused by the passenger viewing the display device.

[0106] Among them, the prompt signal includes displaying warning information on a display device or playing a warning voice, so as to conveniently notify passengers of relevant prompt content.

[0107] In some embodiments, the display parameters include at least one of a display scrolling speed, a switching speed, and a refresh rate; the motion sickness risk level includes at least two levels set from low to high; the motion sickness adjustment strategy corresponding to the motion sickness risk level from low to high has an adjustment level of the scrolling speed and / or the switching speed set in a decreasing manner from high to low; the motion sickness adjustment strategy corresponding to the motion sickness risk level from low to high has an adjustment level of the refresh rate set in an increasing manner from low to high.

[0108] In this embodiment, there are four levels of motion sickness risk from high to low, namely, level 1, level 2, level 3, and level 4, and four corresponding motion sickness adjustment strategies are set respectively;

[0109] When the motion sickness risk level is level 1, the corresponding motion sickness adjustment strategy is to use normal display scrolling speed, switching speed and refresh rate;

[0110] When the motion sickness risk level is the second level, the corresponding motion sickness adjustment strategy is to reduce the screen scrolling speed to 50%-75% of the normal speed (according to the coefficient), reduce the flickering effect when the screen switches. At the same time, the refresh rate is increased (according to the increase in the coefficient, the fps is increased by a certain unit, such as 30%-60%, and the refresh rate is increased by 1fps for every 1% increase);

[0111] When the motion sickness risk level is level 3, the corresponding motion sickness adjustment strategy is to reduce the screen scrolling speed to 50% or less of the normal speed, and perform smooth transition processing on screen switching, such as using a gradient effect instead of abrupt switching. At the same time, the refresh rate continues to increase (according to the increase in the coefficient, the fps will be increased by a certain number of units, such as 2fps for every 1% increase).

[0112] When the motion sickness risk level is level four, the corresponding motion sickness adjustment strategy is to force users to stop using their mobile phones and look into the distance to relieve user fatigue.

[0113] In some embodiments, Figure 7 As shown, the display parameters also include generating moving dots and the number, speed and / or size of the moving dots; the moving direction of the moving dots is opposite to the moving direction of the vehicle; the motion sickness adjustment strategy corresponding to the motion sickness risk level from low to high sets the adjustment level of the number, speed and / or size of the moving dots in an incremental setting from low to high.

[0114] Specifically, by setting the motion dots, it is possible to help alleviate the motion sickness reaction of passengers and further improve the passenger experience. Among them, by installing a level detector in the display device or control device implemented by the control method, the speed of the vehicle is detected, and a motion dot prompt corresponding to the vestibular movement direction (opposite to the vehicle movement direction) is given, thereby facilitating the relief of the user's motion sickness.

[0115] Furthermore, the moving dots are symmetrically distributed on both sides of the display area of ​​the display device to improve the viewing experience of passengers and effectively alleviate passengers' motion sickness.

[0116] Furthermore, when the motion sickness risk level is level 1, the dots may be the system default value;

[0117] When the motion sickness risk level is detected to be the second or third level, the number and size of the dots will change to x times the original value, and the relative speed will also change to y times the original value;

[0118] When the motion sickness risk factor is detected to be level four or higher, the system will force the user to stop using the mobile phone.
