[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0032] Exemplary Application Scenarios

[0033] Figure 1 Shown is a schematic diagram of a scenario applicable to the present application. This scenario is an application scenario of the learning machine 10. The learning machine 10 includes a main controller 11, a distance detection device 12, and a display screen 13, and there is a communication connection relationship among the main controller 11, the distance detection device 12, and the display screen 13.

[0034] Specifically, the distance detection device 12 is used to determine the sitting height of the user in the case where the user has an eye protection request for the electronic device. The distance detection device 12 may be a distance detection sensor. Specifically, it may be a one-dimensional time-of-flight sensor (One-dimensional Time of Flight, 1D-TOF), or a three-dimensional time-of-flight sensor (Three-dimensional Time of Flight, 3D-TOF). The embodiments of the present application do not make specific limitations on the structure of the distance detection device 12.

[0035] The main controller 11 is used to determine the first eye protection distance between the user and the electronic device and the first eye protection height between the electronic device and the user according to the sitting height of the user determined by the distance detection device 12, and display the first eye protection distance and the first eye protection height to the user through the display screen 13, so that the user can adjust the relative position relationship with the electronic device based on the first eye protection height and the first eye protection distance. Further, the main controller 13 may be a central processing unit (Central Processing Unit, CPU).

[0036] In addition, in another embodiment, while the main controller displays the first eye protection distance and the first eye protection height to the user through the display screen 13, it can also actively control the up and down movement and / or the front and back movement of the electronic device through a control unit (not shown in the figure) built in the electronic device to adjust the relative position relationship between the user and the electronic device.

[0037] Exemplary Method

[0038] Figure 2 Shown is a schematic flowchart of a distance determination method provided by an exemplary embodiment of the present application. As Figure 2As shown in the figure, the distance determination method provided by the embodiments of the present application includes the following steps.

[0039] Step S210: In response to the eye protection request of the user of the electronic device, determine the sitting height of the user.

[0040] Exemplarily, the eye protection request of the user may be that the user turns on the eye protection assistant on the electronic device. Further, after the user turns on the eye protection assistant on the electronic device, the distance detection device may further determine the sitting height of the user.

[0041] Step S220: Based on the sitting height, determine the first eye protection distance between the user and the electronic device, and the first eye protection height of the electronic device relative to the user, so as to adjust the relative position relationship between the user and the electronic device based on the first eye protection distance and the first eye protection height.

[0042] Exemplarily, the first eye protection distance and the first eye protection height between the user and the electronic device may be determined by the eye protection distance formula and the eye protection height formula.

[0043] Exemplarily, the eye protection distance formula is The eye protection height formula is Where d represents the eye protection distance, h represents the eye protection height, and H represents the sitting height of the user.

[0044] Exemplarily, the first eye protection distance and the first eye protection height between the user and the electronic device may also be determined by using the eye protection distance and eye protection height detection model. For example, a large number of training sample sets are collected, and each training sample set includes the sitting height sample data of the user, as well as the eye protection distance sample data and eye protection height sample data suitable for the user. Using the training sample set and the pre-set target loss function, the network model to be trained is trained to obtain the eye protection distance and eye protection height detection model. Further, the eye protection distance and eye protection height detection model is deployed in the electronic device. When the electronic device collects the sitting height of the user, the corresponding first eye protection distance and first eye protection height of the user can be automatically obtained by using this model.

[0045] It should be noted that the determination methods of the first eye protection distance and the first eye protection height provided by the embodiments of the present application are only examples, and are not specific limitations thereto. Those skilled in the art may select specific methods to determine the eye protection distance and eye protection height of the user according to the actual situation.

[0046] The distance determination method provided by the embodiments of the present application determines the sitting height of the user when there is an eye protection request from the user of the electronic device, and then determines the first eye protection distance and the first eye protection height between the user and the electronic device based on the sitting height of the user, so as to adjust the relative position relationship between the user and the electronic device based on the first eye protection distance and the first eye protection height. Different from the solution of setting a fixed eye protection distance and eye protection height when the electronic device leaves the factory, the embodiments of the present application provide a suitable eye protection distance and eye protection height for each user of the electronic device. That is, for different users of the electronic device, the corresponding eye protection height and eye protection distance are also different. In addition, for the same user of the electronic device, if the sitting height of the user is different at different times, the corresponding eye protection distance and eye protection height of the user are also different. That is to say, the eye protection height and eye protection distance provided by the embodiments of the present application change dynamically according to the user and the sitting height of the user, so as to better protect the eyes of the user.

[0047] Figure 3 The following is a schematic flowchart of the distance determination method provided by another exemplary embodiment of the present application. On the basis of Figure 2 the embodiment shown, Figure 3 the embodiment shown is extended. The following focuses on Figure 3 the differences between the embodiment shown and Figure 2 the embodiment shown, and the same parts will not be described again.

[0048] As Figure 3 shown, in the embodiments of the present application, after determining the first eye protection distance between the user and the electronic device and the eye protection height of the electronic device relative to the user, the following steps are further included.

[0049] Step S310, determine the current usage mode of the electronic device.

[0050] Step S320, based on the current usage mode, determine the second eye protection distance between the user and the electronic device.

[0051] Exemplarily, the usage mode may include a viewing mode, a writing mode, and so on. The second eye protection distance determined in the embodiments of the present application is calculated according to the current usage mode of the electronic device under the condition that the first eye protection height remains unchanged. Further, due to different current usage modes of the electronic device, the eye protection distance between the user and the electronic device is also different.

[0052] After determining the second eye protection distance between the user and the electronic device, the user can actively adjust the relative position relationship with the electronic device according to the second eye protection distance, or the electronic device can actively adjust the relative position relationship with the electronic device according to the second eye protection distance.

[0053] Through the distance determination method provided by the embodiments of the present application, the purpose of determining the second eye protection distance corresponding to the current usage mode according to different current usage modes of the electronic device is achieved, so as to adjust the relative position relationship between the user and the electronic device according to the second eye protection distance. That is, the embodiments of the present application provide a feasible implementation solution for the determination method of the eye protection distance between the user and the electronic device in a specific usage scenario.

[0054] Figure 4 The following is a schematic flowchart of determining the second eye protection distance between the user and the electronic device provided by an exemplary embodiment of the present application. Figure 3 Based on the embodiment shown above, Figure 4 the embodiment shown below is extended. Figure 4 The differences between the embodiment shown in Figure 3 and the embodiment shown above will be mainly described below, and the same parts will not be repeated.

[0055] As Figure 4 shown, in the embodiments of the present application, based on the current usage mode, determining the second eye protection distance between the user and the electronic device includes the following steps.

[0056] Step S410, when the current usage mode is the viewing mode, determine the eye position information of the user.

[0057] Exemplarily, the eye position information of the user refers to the central position coordinates of the two eyes of the user in the reference coordinate system, where the reference coordinate system includes the coordinate system of the distance detection device.

[0058] Step S420, based on the eye position information and the maximum display width information of the electronic device, determine the second eye protection distance between the user and the electronic device.

[0059] The following Figure 5 takes an example to illustrate how to determine the second eye protection distance between the user and the electronic device according to the eye position information and the maximum display width information of the electronic device.

[0060] Specifically, determine the midpoint position information of the interpupillary distance according to the eye position information; determine the comfortable angular range of the human eye when the user views the electronic device, and the comfortable angular range of the human eye refers to the angular range between the midpoint of the interpupillary distance and the two ends of the wide side of the display screen of the electronic device in the comfortable state when the user views the electronic device. Further, according to the midpoint position information of the interpupillary distance, the maximum display width information of the electronic device, and the comfortable angular range of the human eye, use trigonometric functions to determine the second eye protection distance between the user and the electronic device.

[0061] Under normal circumstances, the comfortable viewing angle range of a user's eyes when sitting still and watching an electronic device is from 30° to 60°. When it is less than 30°, the user is relatively close to the electronic device, which is not friendly to the eyes. When it is greater than 60°, the user will frequently turn their head and eyes, which places a heavy burden on the eyes and is likely to cause discomfort symptoms such as visual fatigue and dizziness. Figure 5 The following shows a schematic diagram for determining the second eye protection distance between a user and an electronic device provided by an exemplary embodiment of the present application. As Figure 5 shown, a1 is equal to 60°, a2 is equal to 30°, and A represents the maximum display width of the electronic device. It is generally considered that the midpoint of the eye distance is located at the center of the display screen. At this time, the lines connecting the midpoint of the eye distance to both ends of the wide side of the display screen form an isosceles triangle. Starting from the midpoint of the eye distance, a perpendicular line is drawn to the wide side of the display screen, and the length of the perpendicular line is the second eye protection distance between the user and the electronic device to be solved. As Figure 5 shown, d 1 is the second eye protection distance when the comfortable viewing angle of the human eye is 60° to be solved, and d 2 is the second eye protection distance when the comfortable viewing angle of the human eye is 30° to be solved. According to the calculation method of the tangent function of a right triangle in trigonometric functions, It can be seen that the second eye protection distance is greater than or equal to d 1 and less than or equal to d 2 .

[0062] In the embodiment of the present application, the eye protection distance range at which the human eye is relatively comfortable when watching an electronic device can be accurately calculated. Through the solution in the embodiment of the present application, a reference eye protection distance range is provided for the user in the viewing mode, so as to adjust the relative position relationship between the electronic device and the user based on this eye protection distance range.

[0063] Exemplarily, according to the calculated eye protection distance range, the user can actively adjust the distance d between themselves and the electronic device, as long as it is ensured that the distance d is within the second eye protection distance range. In addition, if the electronic device is built-in with a control unit for controlling the up and down movement and / or left and right movement of the electronic device, the electronic device can also actively adjust the distance d between itself and the user based on the second eye protection distance. Similarly, as long as it is ensured that the distance d is within the eye protection distance range.

[0064] Figure 6 The following shows a schematic flowchart for determining the second eye protection distance between a user and an electronic device provided by another exemplary embodiment of the present application. On the basis of the embodiment shown in Figure 3 an embodiment is extended as shown in Figure 6 and the following focuses on describing the embodiment shown in Figure 6 and the embodiment shown in Figure 3The differences of the illustrated embodiments will not be elaborated as the same parts will not be repeated.

[0065] As Figure 6 shown, based on the current usage mode, determining a second eye protection distance between the user and the electronic device includes the following steps.

[0066] Step S610, when the current usage mode is the writing mode, determining the user's arm length information, writing posture information, and writing pen size information.

[0067] Specifically, the arm length information includes the length of the user's arm, the writing posture information includes the distance between the user's body and the electronic device and the degree of body inclination in the writing mode, and the writing pen size information includes the length of the writing pen.

[0068] Step S620, based on the arm length information, writing posture information, and writing pen size information, determining the second eye protection distance between the user and the electronic device.

[0069] Specifically, the writing posture information includes the position information of the user's hand holding the writing pen. Based on the distance detection device to detect the user's arm length, and according to the writing pen size information, the position information of the hand holding the writing pen, and the user's arm length, determining the second eye protection distance between the user and the electronic device.

[0070] For example, the size information of the writing pen is 15 cm, the user holds the writing pen at the 1 / 3 position, that is, the user's hand is 5 cm away from the writing end of the writing pen, and the user's arm length is 65 cm, then the second eye protection distance between the user and the electronic device is (65 + 5) cm, that is, the second eye protection distance is 70 cm.

[0071] In addition, if the user writes directly with the hand, the second eye protection distance between the user and the electronic device can also be determined based on the preset suitable distance range from the palm to the display screen and the user's arm length information.

[0072] For example, the preset suitable distance range from the palm to the display screen is 2 - 10 cm, and the user's arm length is 65 cm, then the second eye protection distance between the user and the electronic device is 67 - 75 cm.

[0073] As Figure 5 described in the illustrated embodiment, according to the calculated second eye protection distance, the user can actively adjust the distance d from the electronic device, or use the control unit built in the electronic device to control the up and down movement and / or left and right movement of the electronic device to adjust the relative position relationship between the user and the electronic device. Similarly, no matter how the adjustment method is, as long as the distance d satisfies the second eye protection distance.

[0074] Through the solution in the embodiments of the present application, the purpose of determining the second eye protection distance between the user and the electronic device according to the user's arm length, writing posture, and writing pen size is achieved. While enriching the scenarios for determining the eye protection distance, a suitable eye protection distance for the user in this scenario is provided, facilitating the adjustment of the relative position relationship between the user and the electronic device based on this eye protection distance.

[0075] Figure 7 The following is a schematic flowchart of the process for determining the sitting height of the user provided by an exemplary embodiment of the present application. Figure 2 Based on the embodiment shown, Figure 7 the embodiment shown is extended, Figure 7 and the differences between the embodiment shown Figure 2 and the embodiment shown are emphasized below. The same parts will not be elaborated again.

[0076] As Figure 7 shown, in the embodiments of the present application, determining the sitting height of the user includes the following steps.

[0077] Step S710, use the three-dimensional time-of-flight sensor of the electronic device to detect the sitting height of the user.

[0078] After determining the first eye protection distance between the user and the electronic device based on the sitting height, and the first eye protection height of the electronic device relative to the user (step S220), the following steps are included.

[0079] Step S720, turn off the three-dimensional time-of-flight sensor of the electronic device.

[0080] Step S730, use the one-dimensional time-of-flight sensor of the electronic device to detect the actual distance between the user and the electronic device, so as to remind the user to adjust the relative position relationship with the electronic device based on the actual distance.

[0081] Exemplarily, if the actual distance between the user and the electronic device is less than the first eye protection distance, the relative position relationship between the user and the electronic device is adjusted according to the first eye protection distance, so that the actual distance between the user and the electronic device meets the first eye protection distance. Among them, the first eye protection distance can be a determined value or a value range.

[0082] In an embodiment of the present application, after detecting the sitting height of a user using a three-dimensional time-of-flight sensor, the eye protection height and eye protection distance of the user can be calculated. During the subsequent use of the electronic device, the three-dimensional time-of-flight sensor is turned off, and the one-dimensional time-of-flight sensor is turned on to detect the sitting posture and usage mode of the user, so as to provide the appropriate eye protection distance for the user according to the current state of the user. Since the one-dimensional time-of-flight sensor has lower power consumption than the three-dimensional time-of-flight sensor, the solution of the embodiment of the present application can not only calculate the appropriate eye protection distance for the user, but also save power consumption.

[0083] Figure 8 The following is a schematic flowchart of a distance determination method provided by another exemplary embodiment of the present application. On the basis of Figure 2 the embodiment shown, the embodiment shown Figure 8 is extended. The following focuses on Figure 8 the differences between the embodiment shown and Figure 2 the embodiment shown, and the same parts will not be elaborated.

[0084] As Figure 8 shown, in an embodiment of the present application, before determining the sitting height of the user in response to the eye protection request of the user of the electronic device, the following steps are further included.

[0085] Step S810: When the electronic device is started for the first time, present a height input window to the user.

[0086] Step S820: In response to the input operation of the user in the height input window, obtain the height information of the user.

[0087] Step S830: Based on the height information, determine the third eye protection distance between the user and the electronic device, and the second eye protection height of the electronic device relative to the user.

[0088] Specifically, after obtaining the height information of the user, the third eye protection distance and the second eye protection height between the user and the electronic device can be calculated through the Figure 2 eye protection distance calculation formula and eye protection height calculation formula described in, where H represents the height data of the user.

[0089] Through the solution of the embodiment of the present application, the basis for determining the eye protection distance and eye protection height is further enriched, and the relative position relationship between the user and the electronic device is adjusted according to the third eye protection distance and the second eye protection height when the user does not issue an eye protection request. That is, even if the user does not issue an eye protection request, the electronic device can provide the user with an initial eye protection distance (the third eye protection distance) and an initial eye protection height (the second eye protection height) for the user to refer to.

[0090] Figure 9 The following is a schematic flow chart of the distance determination method provided by another exemplary embodiment of the present application. Based on Figure 2 the embodiment shown, Figure 9 an extended embodiment is derived. Below, the differences between the Figure 9 embodiment shown and the Figure 2 embodiment shown will be mainly described, and the same parts will not be elaborated.

[0091] As Figure 9 shown, after determining the first eye protection distance between the user and the electronic device and the first eye protection height of the electronic device relative to the user based on the sitting height, the following steps are further included.

[0092] Step S910, collect the posture data of the user.

[0093] Specifically, the posture data includes the head posture deflection angle and the body tilt angle.

[0094] Step S920, determine whether the posture data meets the abnormal display condition.

[0095] The abnormal display condition is a defined range of data for the head posture deflection angle and the body tilt angle. Exemplarily, when the head posture deflection angle is less than or equal to 30°, it is normal; when it is greater than 30°, it meets the posture abnormal display condition. When the body tilt angle is less than or equal to 45°, it is normal; when the body tilt angle is greater than 45°, it meets the posture abnormal display condition.

[0096] Exemplarily, if the judgment result of step S920 is yes, that is, the posture data meets the abnormal display condition, then step S930 is executed; if the judgment result of step S920 is no, that is, the posture data does not meet the abnormal display condition, then step S940 is executed.

[0097] Step S930, send a prompt message to the user, and / or adjust the relative position relationship between the electronic device and the user.

[0098] In the embodiment of the present application, at least two ways are provided to adjust the relative position relationship between the user and the electronic device. First, according to the prompt message, the user actively adjusts his own posture data until it does not meet the abnormal display condition. Second, according to the prompt message, the electronic device actively adjusts its own height and distance relative to the user until the posture data of the user relative to the electronic device does not meet the abnormal display condition.

[0099] Step S940, end.
