Abstract

The invention relates to a watching distance prompting method and device, television equipment and a storage medium. The method comprises the steps of detecting position information of a target object relative to television equipment in the process that the target object watches the television, and determining prompt information corresponding to the position information under the condition that the position information meets a prompt condition, namely generating the corresponding prompt information according to the watching distance of the target object; and displaying the prompt information on the television equipment to prompt the target object watching the television to adjust the watching distance. Because the prompt information can influence the watching experience of the target object, the prompt information cannot be displayed only when the watching distance of the target object does not meet the prompt condition, the watching distance of the target object is intervened in this way, and a reasonable watching distance is kept between the target object and the television equipment.

Example Embodiment

[0044] In order to make the objects, technical solutions and advantages of the present application, the present application will be described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended to explain the present application and is not intended to limit the present application.
[0045] The viewing distance of the present application is applied to the control unit in the television device, and the control unit communicates with the millimeter wave radar sensor and the display screen, and controls the operating state of the display screen according to the information collected according to the millimeter wave radar sensor.
[0046] In one embodiment, if figure 1 As shown, a viewing distance prompt method is provided, and the method is applied to the television device as an example, including the following steps:
[0047] In step S210, when the target object is detected, the position information of the target object relative to the television device is acquired.
[0048] Among them, the target object refers to the user who viewing the television device. The target object can be one or more users, obtain the location information of the target object relative to the television device, specifically, can be scanned by a laser radar sensor or collecting portraits by a camera.
[0049] In step S220, in the case where the position information satisfies the prompt condition, the corresponding prompt information is determined according to the position information.
[0050] Wherein, the location information satisfies the prompt condition refers to the viewing distance of the target object, and it is necessary to prompt the target object to adjust the viewing distance. According to the location information, the corresponding prompt information is generated, and the information is used to simulate display in the display interface of the television device. The positional relationship between the target object is between the television device, that is, converts the position relationship between the target object to the television device to correspond to the corresponding prompt information, and the prompt information corresponding to the different position information is also different.
[0051] Step S230 shows the prompt information.
[0052]Among them, the positional relationship between the target object and the television device is converted to the prompt information displayed in the display interface of the television device, informs the target object, inform the location relationship between the television devices, to prompt watch TV target object Adjust the viewing distance, since the prompt information affects the viewing experience of the target object, only the viewing distance of the target object does not display the prompt information without satisfaction, in this way, the target object is intervened, so that the target object is Keep a reasonable viewing distance between television devices.
[0053] Wherein, step S210 can include:
[0054] Gets the distance and bias angle of the target object relative to the television device.
[0055] like figure 2 As shown, specifically via the millimeter wave radar sensor mounted on the television device and the location information of the target object and the target object, the millimeter wave radar sensor uses millimeterwave, usually millimeter wave refers to the 30 ~ 300GHz frequency domain (wavelength is 1 ~ 10mm). The wavelength of millimeter wave is between centimeter and optical waves, so the advantages of millimeter waves and microwave guidance and photoelectric guidance. Compared to optical sensors such as cameras, infrared, laser, millimeter radar penetrates fog, smoke, dust, strong anti-interference ability, and has a full-time (except heavy rain days). Here, 60 GHz TI millimeter wave radar sensor is used to scan the location information of the target object.
[0056] The position information includes the distance and bias angle between the target object and the television device upper millimeter wave radar sensor, and the bias angle refers to the angle between the target object and the linear scanning wave emitted by the millimeter wave radar sensor, and the linear scan wave is perpendicular to the television device. Display interface, for example, figure 2 The target object is located on the left side of the straight line scan wave, the polar angle is positive; the target object is located on the right side of the straight line scan wave, and the biased angle is negative. Alternatively, the target object is located on the right side of the straight line scan wave, the polar angle is positive; the target object is located on the left side of the straight line scan wave, and the bias direction is negative.
[0057] The above step S220 specifically includes:
[0058] In step S2201, in the case where the distance is less than the threshold, the replacement icon is determined in accordance with the distance and the bias angle, the replacement icon is determined in the display position in the display interface, and the distance of the distance is located, the distance range corresponding to the distance indication style and The distance indicates the display content corresponding to the style.

[0060] The threshold is used to determine whether the criterion is met, the threshold can be customized according to the requirements of the viewing distance depending on the requirements of the viewing distance. If the user wants to control the viewing distance, the threshold value can be set to a larger value, the more value of the threshold Big, it means that the easier it is to trigger the prompt information, and the user is prompted to remotely travel from the TV device with a high frequency; the smaller the value of the threshold, the less it is not easy to trigger the prompt information, then the frequency of the prompt is, the lower the frequency. The less is not conducive to the protection of your eyes. The usual threshold is set to 3 meters, that is, the distance between the user and the television device is less than 3 meters, the corresponding prompt information is required to prompt the user away from the television device.
