Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a prompting method based on a display device according to an embodiment of the present disclosure. In the embodiment of the application, the main execution body of the prompting method is a prompting device based on display equipment. The display device may be a television, a display connected to the host computer by wire, or an integrated machine integrated with the host computer. The prompting device can be a server or a processor in the server. Here, the server may be a smartphone, a tablet computer, a desktop computer, or the like.
As shown in fig. 1, a prompting method based on a display device provided in an embodiment of the present application may include S101 to S103, which are detailed as follows:
in S101, if a preset operation for performing gesture prompt when the display device is in an on state is detected, a first distance value set between the display device and the user within a first preset time period is obtained.
In the embodiment of the application, when the display device is in the open state, the prompting device can detect whether the preset operation for performing the gesture prompt when the display device is in the open state exists. The preset operation may be determined according to actual needs, and is not limited herein. For example, the preset operation may be clicking a preset control, that is, if it is detected that the user clicks the preset control of the display device when the display device is in an open state, the prompting device considers that the preset operation for performing the gesture prompt when the display device is in the open state is detected.
In an embodiment of the application, the prompting device may preset that the display device has two working modes when being in an on state, one of which is a common mode, that is, a working mode in which the gesture prompt is not performed on the user; one mode is a prompt mode, i.e., a working mode in which a user can be prompted for a posture. Therefore, the preset operation that the prompting device detects that the display device is in the on state for gesture prompting may be: the display device is detected to be in a working mode of a prompt mode.
When the prompting device detects a preset operation for performing gesture prompting when the display device is in an on state, the prompting device may acquire a first set of distance values between the display device and the user within a first preset time period. The first preset time period may be set according to actual needs, and is not limited herein, and for example, the first preset time period may be 30 minutes. Each distance value in the first set of distance values refers to a distance between the display device and the user.
In an implementation manner of the embodiment of the present application, the prompting apparatus may obtain and store a plurality of first distance values between the display device and the user in advance. When the prompting device detects a preset operation for gesture prompting when the display equipment is in an open state, a first distance value set in a first preset time period is directly acquired from the prompting device.
In another implementation manner of the embodiment of the present application, the prompting apparatus may further acquire, from another device, a first set of distance values between the display device and the user within a first preset time period. For example, the prompting device may obtain, through the ranging module, a first set of distance values between the display device and the user within a first preset time period. The distance measurement module can acquire the distance value between the display equipment and the user in real time. By way of example and not limitation, the ranging module may be an ultrasonic range finder.
In practical applications, since a fixed obstacle (such as a wall) usually exists in front of the display device, the prompting device may also obtain the distance value between the display device and the fixed obstacle, and therefore, in order to determine that the distance value obtained by the prompting device is the distance value between the display device and the user, the prompting device may compare each distance value in the obtained distance value set with the second preset distance threshold. Wherein the second preset distance threshold is a distance value between the display device and the fixed obstacle.
And if the prompting device detects that each distance value in the distance value set is smaller than a second preset distance threshold value, determining that each distance value in the acquired distance value set is a distance value between the display device and the user.
In S102, determining a posture variation amplitude of the user within the first preset time period based on the first distance value set.
In the embodiment of the application, when the user uses the display device, the distance value between the user and the display device is in a constantly changing state along with the action of the user, so that the prompting device can judge the gesture change amplitude of the user in the first preset time period based on the first distance value set. That is to say, the prompting device may determine the gesture change amplitude of the user in the first preset time period through the change between the distance values at different times in the first preset time period.
Specifically, the prompting device may determine the gesture change amplitude of the user within the first preset time period through steps S201 to S203 shown in fig. 2, which are detailed as follows:
in S201, the distance value at the start time of the first preset time period is determined as an initial value.
In this embodiment, after obtaining the first distance value set in the first preset time period, the prompting device may determine, as an initial value, that is, a reference value, the distance value at the start time of the first preset time period, in order to determine whether the distance values at different times in the first preset time period change significantly.
In S202, a difference value between the initial value and each distance value in the first set of distance values is calculated, so as to obtain a difference value set.
In this embodiment, the prompting device may calculate a difference between the initial value and each distance value, except the initial value, in the first distance value set when determining the initial value in the first preset time period, to obtain a difference value set. Wherein the set of differences comprises the difference between the initial value and each distance value.
In one embodiment of the present application, since the distance values in the first distance value set within the first preset time period are too many and the calculation time is long, the prompting device may calculate the difference between the initial value and the distance value in the first distance value set at every preset time interval, thereby reducing the calculation amount. The preset time interval may be set according to actual needs, and is not limited herein.
In S203, determining a posture variation range of the user in the first preset time period according to the difference set.
In this embodiment, since the prompting device may determine, by a difference between the initial value and each distance value in the first distance value set in the first preset time period, a change in distance between the display device and the user in the first preset time period, so as to determine whether the posture of the user changes, the prompting device may determine, by the difference set, a posture change amplitude of the user in the first preset time period.
In one embodiment of the application, since the user may be able to ignore the slight change of the user posture when using the display device, that is, when the user posture changes slightly, the user posture may be regarded as not changing, and therefore, the prompting device may compare the posture change amplitude of the user with the first preset threshold after determining the posture change amplitude within the first preset time period. If the prompting device detects that the attitude change amplitude is smaller than or equal to a first preset threshold, executing a step S103; if the prompting device detects that the gesture change amplitude is larger than a first preset threshold value, the gesture of the user is adjusted within a first preset time period, and the prompting device does not need to prompt the user to change the gesture.
In S103, if the posture variation range in the first preset time period is less than or equal to a first preset threshold, prompting the user to change the posture.
In the embodiment of the application, after the prompting device detects that the posture change amplitude of the user is smaller than or equal to the first preset threshold, it can be determined that the posture of the user is not changed in the first preset time period, that is, the posture of the user is not changed all the time when the user faces the display device in the first preset time period, so that the prompting device can prompt the user to change the posture, and the purpose of protecting the cervical vertebra and the vertebra of the user is achieved.
In one embodiment of the present application, the prompting device may be provided with an information prompting module. Therefore, the prompting device can control the information prompting module to output the first prompting information when prompting the user to change the posture. Wherein the first prompt message is used for prompting the user to change the gesture. By way of example and not limitation, the information prompt module may be an alarm or an indicator light.
As can be seen from the above, according to the prompting method based on the display device provided in the embodiment of the present application, if the preset operation for performing the gesture prompt when the display device is in the on state is detected, the first distance value set between the display device and the user within the first preset time period is obtained; judging the attitude change amplitude of the user in a first preset time period based on the first distance value set; and if the posture change amplitude is smaller than or equal to a first preset threshold value, prompting the user to change the posture. According to the prompting method based on the display equipment, when the preset operation is detected, the first distance value set of the user in the first preset time period can be automatically obtained, the behavior of the user is automatically detected, and when the gesture change amplitude is detected to be smaller than or equal to the first preset threshold value, the fact that the gesture of the user is not changed all the time in the first preset time period is determined, namely that the fact that the user has incorrect behavior when using the display equipment is detected, is indicated, and the user is prompted to change the gesture.
In another embodiment of the present application, since the user is prone to cause visual fatigue when the user is too close to the display device and affects the eyesight of the user, after the first distance value set between the display device and the user within the first preset time period is obtained, the prompting device may further compare each distance value in the first distance value set with the first preset distance threshold. If the prompting device detects that a distance value smaller than or equal to a first preset distance threshold exists in the first distance value set, the prompting device executes step S301 shown in fig. 3; if the prompting device detects that each distance value in the first distance value set is greater than the first preset distance threshold value, it is determined that the distance between the user and the display device does not affect the eyesight of the user, and therefore the prompting device does not need to prompt the user to be far away from the display device. Wherein the first preset distance threshold may be a minimum value of a safe distance between the display device and the user.
It should be noted that the first preset distance threshold may be determined according to a size of a display device screen, and specifically, the larger the display device screen is, the larger the first preset distance threshold is.
Referring to fig. 3, fig. 3 is a flowchart illustrating an implementation of a prompting method based on a display device according to another embodiment of the present application. With respect to the embodiment corresponding to fig. 1, after S101, the method for prompting based on a display device in this embodiment may further include S301, which is detailed as follows:
in S301, if it is detected that a distance value smaller than or equal to a first preset distance threshold exists in the first distance value set, the user is prompted to move away from the display device.
In this embodiment, the prompting device may prompt the user to move away from the display device when detecting that a distance value smaller than or equal to the first preset distance threshold exists in the first distance value set, which indicates that the distance between the user and the display device is smaller than the minimum value of the safe distance between the user and the display device.
In an embodiment of the present application, in conjunction with S103, the prompting device is provided with an information prompting module. Therefore, when the prompting device prompts the user to be far away from the display equipment, the information prompting module can be controlled to output the second prompting information. And the second prompt message is used for prompting the user to get away from the display equipment.
As can be seen from the above, in the prompting method based on the display device provided in this embodiment, by detecting whether a distance value smaller than or equal to the first preset distance threshold exists in the first distance value set, if it is detected that a distance value smaller than or equal to the first preset distance threshold exists in the first distance value set, the user is prompted to be far away from the display device, so that the eyesight of the user is protected.
In yet another embodiment of the present application, the first preset time period includes at least one second preset time period. The second preset time period may be set according to actual needs, and is not limited herein, and for example, the second preset time period may be 5 minutes. Based on this, please refer to fig. 4, and fig. 4 is a flowchart illustrating an implementation of a prompting method based on a display device according to yet another embodiment of the present application. With respect to the embodiment corresponding to fig. 1, the prompting method based on the display device in this embodiment may further include, after S101, S401 to S403, which are detailed as follows:
in S401, a second distance value set in the second preset time period is obtained.
In this embodiment, since the second preset time period is included in the first preset time period, the prompting device may obtain the second distance value set in the second preset time period from the first distance value set in the first preset time period.
For example, assuming that the first preset time period is 30 minutes, and the second preset time period is 5 minutes, the prompting device may use the first distance value set within any 5 minutes, which is obtained from the first distance value sets within 30 minutes of the first preset time period, as the second distance value set within the second preset time period.
In S402, determining a posture variation amplitude of the user within the second preset time period based on the second distance value set.
In this embodiment, the prompting device may determine the gesture variation range of the user in the second preset time period by the variation between the distance values at different times in the second preset time period.
Specifically, the prompting device may determine a distance value at a starting time of a second preset time period as an initial value of the second preset time period, calculate a difference between the initial value of the second preset time period and a distance value, except the initial value of the second preset time period, in the second distance value set, obtain a difference value set of the second preset time period, and determine a posture change amplitude of the user in the second preset time period according to the difference value set of the second preset time period.
In this embodiment, since the prompting device may determine, by using a difference between the initial value and each distance value in the second distance value set in the second preset time period, a change in distance between the display device and the user in the second preset time period, so as to determine whether the posture of the user changes, the prompting device may determine, by using the difference set, a posture change amplitude of the user in the second preset time period.
In an embodiment of the present application, after determining the gesture change amplitude of the user within the second preset time period, the prompting device may compare the gesture change amplitude within the second preset time period with a second preset threshold. If the prompting device detects that the attitude change amplitude in the second preset time period is larger than a second preset threshold, executing step S403; if the prompting device detects that the gesture change amplitude is smaller than or equal to the second preset threshold, it indicates that the user does not change the gesture within the second preset time period, that is, the user is using the display device, and therefore the prompting device can control the display device to keep the on state. The second preset threshold may be set according to actual needs, and is not limited herein.
It should be noted that the second preset threshold is greater than the first preset threshold.
In S403, if the gesture variation amplitude in the second preset time period is greater than a second preset threshold, the display device is turned off.
In this embodiment, when detecting that the gesture variation amplitude in the second preset time period is greater than the second preset threshold, the prompting device may determine that the user does not use the display device in the second preset time period, that is, the user does not watch the video through the display device, and therefore, the prompting device may turn off the display device.
In another embodiment of the present application, after the prompting device obtains the second distance value set within the second preset time period, it may further determine whether each distance value in the second distance value set is zero. If the prompting device detects that each distance value in the first distance value set is zero, it is determined that the user is not in front of the display device, that is, the user does not use the display device, and therefore the prompting device can close the display device.
As can be seen from the above, in the prompting method based on the display device provided in this embodiment, the second distance value set in the second preset time period is obtained; judging the attitude change amplitude of the user in a second preset time period based on the second distance value set; and if the posture change amplitude in the second preset time period is larger than a second preset threshold value, closing the display equipment. According to the prompting method, when the gesture change amplitude in the second preset time period is detected to be larger than the second preset threshold, the fact that the user does not use the display equipment can be determined, and therefore the prompting device can directly close the display equipment, power consumption of the display equipment is reduced, and the service life of the display equipment is prolonged.
In another embodiment of the present application, the first preset time period includes at least one third preset time period, and the third preset time period is after the second preset time period. The third preset time period may be set according to actual needs, and is not limited herein, and for example, the third preset time period may be 1 minute. Based on this, please refer to fig. 5, wherein fig. 5 is a flowchart illustrating an implementation of a prompting method based on a display device according to another embodiment of the present application. With respect to the embodiment corresponding to fig. 4, the control method of the bench press device in this embodiment may further include, before S403, S501 to S503, which are detailed as follows:
in S501, a third distance value set in the third preset time period is obtained.
In this embodiment, since the third preset time period is included in the first preset time period and is after the second preset time period, the prompting device may obtain, from the first distance value set within the first preset time, a third distance value set within the third preset time period after the second preset time period.
For example, assuming that the first preset time period is 30 minutes, the second preset time period is 5 minutes, and the third preset time period is 1 minute, the prompting device may use the first distance value set within 30 minutes of the first preset time period and the distance value set within any one 1-minute time period after 5 minutes of the second preset time period elapses as the third distance value set within the third preset time period.
In S502, determining a posture variation amplitude of the user within the third preset time period based on the third distance value set.
In this embodiment, the prompting device may determine the gesture variation range of the user in a third preset time period by variation between distance values at different times in the third preset time period.
Specifically, the prompting device may determine a distance value at a starting time of a third preset time period as an initial value of the third preset time period, calculate a difference value between the initial value of the third preset time period and a distance value in the third distance value set except the initial value of the third preset time period, obtain a difference value set of the third preset time period, and determine the posture change amplitude of the user in the third preset time period according to the difference value set of the third preset time period.
In this embodiment, since the prompting device may determine, by using a difference between the initial value and each distance value in the third distance value set in the third preset time period, a change in distance between the display device and the user in the third preset time period, so as to determine whether the posture of the user changes, the prompting device may determine, by using the difference set, a posture change amplitude of the user in the third preset time period.
In an embodiment of the present application, after determining the gesture change amplitude of the user within the third preset time period, the prompting device may compare the gesture change amplitude within the third preset time period with the first preset threshold. If the prompting device detects that the attitude change amplitude in the third preset time period is smaller than or equal to the first preset threshold, executing step S503; if the prompting device detects that the gesture change amplitude is larger than the first preset threshold, it indicates that the user changes the gesture within the third preset time period, that is, the user does not use the display device, and therefore the prompting device can control the display device to keep the off state.
In S503, if the gesture change amplitude in the third preset time period is less than or equal to the first preset threshold, the display device is turned on.
In this embodiment, the gesture variation amplitude of the prompting device in the third preset time period is detected to be less than or equal to the first preset threshold, which indicates that the user needs to use the display device, and therefore, the prompting device may turn on the display device.
As can be seen from the above, in the prompting method based on the display device provided in this embodiment, the third distance value set in the third preset time period is obtained; judging the attitude change amplitude of the user in a third preset time period based on the third distance value set; and if the posture change amplitude in the third preset time period is less than or equal to the first preset threshold, starting the display equipment. According to the prompting method, when the gesture change amplitude in the third preset time period is detected to be smaller than or equal to the first preset threshold, the fact that the user needs to use the display equipment can be determined, therefore, the prompting device can directly start the display equipment, the user does not need to manually start the display equipment, and the working efficiency is improved.
