In order to solve the above problems, embodiments of the present invention provide a distance dynamic prompting method and a terminal device, where the terminal device may acquire an image through a camera, so as to determine that a user is in front of a display screen, and display different distance dynamic prompting interfaces according to different distance ranges between the user and the terminal device, so that not only can an obstacle existing in front of the display screen be intelligently and accurately determined as a face of the user, so as to output correct prompting information, but also a prompt may be output in an animation manner, which is easy for the user to accept, and the scheme enriches output forms of the prompting information.

The following takes a terminal device as an example to exemplarily describe the distance dynamic prompting method provided by the embodiment of the present invention.
The distance dynamic prompting method provided by the embodiment of the invention can be applied to a scene that a user uses terminal equipment.
Example one
As shown in fig. 1, an embodiment of the present invention provides a method for dynamically prompting a distance, where the method may include the following steps:
101. and acquiring a target image through the camera.
In the embodiment of the invention, the terminal equipment can acquire the target image through the camera.
It should be noted that the camera is disposed on the terminal device, and is located on the same side of the terminal device as the display screen.
102. And acquiring the target distance between the user and the terminal equipment.
In the embodiment of the invention, the terminal equipment can detect whether the facial features of the user exist in the target image through a facial recognition technology; and if the terminal equipment detects that the facial features of the user exist in the target image, acquiring the target distance between the user and the terminal equipment.
Optionally, the specific manner for the terminal device to obtain the target distance between the user and the terminal device is as follows: if the terminal equipment is provided with the infrared distance sensor, the terminal equipment can control the infrared distance sensor to emit a first optical pulse signal and receive a second optical pulse signal obtained by reflecting the first optical pulse signal; detecting the interval duration between the first optical pulse signal and the second optical pulse signal; and determining the distance between the user and the terminal equipment according to the interval duration and the light speed.
It should be noted that the infrared distance sensor is one of the distance sensors, and is mostly applied to a terminal device. The infrared distance sensor detects the distance between obstacles by using the principle that infrared signals meet the obstacles at different distances and the reflection time is different. The infrared distance measuring sensor is provided with a pair of infrared signal transmitting and receiving diodes, the transmitting tube transmits an infrared signal with specific frequency, the receiving tube receives the infrared signal with the frequency, and when the detection direction of the infrared signal meets an obstacle, the infrared signal is reflected back to be received by the receiving tube.
Since infrared rays have a small refractive index when passing through other substances, they are not substantially diffused when they travel. When the infrared distance sensor is used for distance measurement, the distance can be calculated according to the time from sending to receiving of an infrared signal and the transmission speed of infrared rays, namely the round-trip transit time delta t of the infrared rays modulated by high frequency on the distance to be measured is utilized, and according to the transmission speed V of the infrared rays, a formula is combined
Figure BDA0002943597720000071
The distance D can be obtained.
For example, when a user approaches a terminal device, a transmitting tube of an infrared distance sensor in the terminal device can transmit a beam of infrared rays, the infrared rays are propagated in a straight line in the air, and when the infrared rays touch the user, the infrared rays are reflected and received by a receiving tube of the infrared distance sensor in the terminal device. Assuming that the infrared distance sensor takes 1.8ns from the emission of infrared rays to the reception of reflected infrared rays, the propagation speed of the infrared rays in the air is 3 x 108m/s, then substituting into the formula, can obtain
Figure BDA0002943597720000072
I.e. it can be stated that the distance between the user and the terminal device is 27 cm.
103. And displaying a distance dynamic prompt interface corresponding to the target distance range.

For example, as shown in fig. 2, assuming that the user is using a mobile phone, the distance dynamic prompting interface on the mobile phone may specifically include: in a target area 21 of the display screen, a distance indication area 22 is displayed, the distance indication area 22 is composed of a plurality of vertical straight lines, and a longer straight line 25, 26 and 27 is arranged at a distance for visually distinguishing different distance sections, a mobile phone mark 23 is positioned at the left end of the distance indication area 22, and a target animation image 24 moving along with the distance between a user and a terminal device is displayed on the distance indication area 22.
Optionally, the displaying of the distance dynamic prompt interface corresponding to the target distance range specifically includes: and displaying a distance indication area in a target area of the display screen, and displaying a target animation image at a target position on the distance indication area, wherein the distance between the target position and the terminal equipment mark corresponds to the target distance.

Through the optional implementation mode, the terminal equipment can display a distance dynamic prompting interface corresponding to the first distance range to the user when the distance between the terminal equipment and the user is within the first distance range, display a first prompting message and output audio prompting information. Therefore, the user can be intuitively prompted that the distance between the user and the display screen is relatively short, so that the user can be far away from the display screen, the output form of the prompt message is enriched, and the prompt effect is obvious.
Optionally, when the target distance is within the second distance range, a distance dynamic prompt interface corresponding to the second distance range is displayed.
And the second distance range is smaller than or equal to the second distance threshold and larger than the third distance threshold. The distance dynamic prompting interface is specifically used for dynamically displaying that the distance between the user and the terminal device is within a second distance range.

Optionally, when the target distance is within the third distance range, a distance dynamic prompt interface corresponding to the third distance range is displayed.
Wherein the third distance range is less than or equal to a third distance threshold. The distance dynamic prompting interface is specifically used for dynamically displaying that the distance between the user and the terminal device is within a third distance range.
Illustratively, assuming that the target distance is 8cm and the third distance threshold is 10cm, the third distance range is less than or equal to 10cm and the distance indicator 25 indicates the third distance threshold of 10 cm. As shown in fig. 4, when the terminal device detects that the target distance 8cm is less than 10cm and is within the third distance range, the terminal device displays a distance dynamic prompt interface corresponding to the third distance range, that is, a target area 21 is defined in the top area of the display screen, a distance indication area 22 is displayed in the target area 21, and a target animation image 24 is displayed at a target position on the distance indication area 22, the target position is located between a position identifier 25 and a mobile phone identifier 23, the distance between the target position and the mobile phone identifier 23 is 0.8cm, and the target distance is indicated to be 8 cm.

Through the optional implementation mode, the terminal device can display a distance dynamic prompting interface corresponding to the third distance range to the user when the distance between the terminal device and the user is within the third distance range, display the first prompting message, and lock the display screen, so that the user can not use the terminal device continuously. When the target distance is within the third distance range, the output form is different from the output form when the target distance is within the first distance range and the second distance range, so that the user can be forced to adjust the posture, the terminal equipment can be continuously used only by keeping away from the display screen, the output form of the prompt message is enriched, and the prompt effect is obvious.
Optionally, the division of the distance range in the embodiment of the present invention is not limited to the division manner in the foregoing implementation manner, and the distance range may be divided into different number of distance ranges or distance ranges with different distances according to different distance threshold settings.

Through the scheme, the terminal equipment can acquire images through the camera, so that the user is judged in front of the display screen, different distance dynamic prompt interfaces are displayed according to different distance ranges between the user and the terminal equipment, so that not only can the obstacle existing in front of the display screen be intelligently and accurately determined to be the face of the user, correct prompt information is output, but also prompt can be output in an animation mode, the user can easily accept the prompt information, and the scheme enriches the output form of the prompt information.
As an optional implementation manner, the acquiring, by the terminal device, the target image by the camera may specifically include: detecting whether the terminal equipment is accessed to a wireless access point or not; if the first wireless access point is accessed currently, whether the identification information of the first wireless access point is matched with the identification information of the target wireless access point on the target vehicle, which is recorded in advance by the terminal equipment, is identified; if the identification information of the first wireless access point is matched with the identification information of the target wireless access point, continuously detecting the motion state of the terminal equipment; and if the first time length of the terminal equipment in the moving state is detected to be longer than a first preset time length, acquiring a target image through the camera.
It should be noted that, if the identification information of the first wireless access point accessed by the terminal device matches the identification information of the target wireless access point on the target vehicle, it may be stated that the user of the terminal device is currently on the target vehicle and the terminal device is using the target wireless access point. Then, the terminal device can continuously detect the motion state of the terminal device, wherein the motion state comprises a moving state or a static state; and if the first time length of the terminal equipment in the moving state is detected to be longer than a first preset time length, acquiring a target image through the camera.
Through the optional implementation mode, the terminal device can accurately judge the current environment of the user through the identification information of the currently accessed wireless access point, if the identification information of the currently accessed first wireless access point is matched with the identification information of the target wireless access point on the target vehicle, the situation that the user is in the target vehicle can be indicated, then the current motion state of the terminal device is detected, and if the first time length of the terminal device in the motion state is longer than the first preset time length, the situation that the terminal device is in the motion state continuously can be indicated. According to the scheme, different scenes are provided for the terminal equipment to acquire the target image, so that the environment where the user is judged to be located by the terminal equipment is accurate, the terminal equipment can acquire the target image according to the motion state, and the terminal equipment is more suitable for actual use scenes.
Further, if it is detected that the first time length of the terminal device in the moving state is longer than a first preset time length, after the target image is acquired, if the target distance between the user and the terminal device is within a first target distance range, a distance dynamic prompt interface corresponding to the first target distance range is displayed.
Note that the first target distance range corresponds to a movement state. The first target threshold is a maximum value of the first target distance range.
Illustratively, when the terminal device is in a moving state, the first distance threshold may be 50cm, the second distance threshold may be 35cm, and the third distance threshold may be 20 cm; the first distance range is less than or equal to 50cm and greater than 35cm, the second distance range is less than or equal to 35cm and greater than 20cm, and the third distance range is less than or equal to 20 cm. And when the target distance is 12cm and is within a third distance range, the terminal equipment displays a distance dynamic prompt interface corresponding to the third distance range.
Through the optional implementation mode, aiming at the mobile state of the terminal equipment, because the terminal equipment and the user are bumpy in the mobile state, a larger distance threshold value is set to form a larger distance range, so that the eyes of the user are protected, and the mobile terminal is more fit with an actual use scene.
Further, after displaying the distance dynamic prompting interface corresponding to the first target distance range, if it is detected that the second time length of the terminal device in the static state is greater than a second preset time length, the target distance between the user and the terminal device is detected again, and if the target distance is within the second target distance range, the distance dynamic prompting interface corresponding to the second target distance range is displayed.
Note that the second target distance range corresponds to a stationary state. The second target threshold is the maximum value of the second target distance range,
it should be noted that the second target distance range is different from the first target distance range, and the second target threshold is smaller than the first target threshold.
Illustratively, when the terminal device is in a stationary state, the first distance threshold may be 30cm, the second distance threshold may be 20cm, and the third distance threshold may be 10 cm; the first distance range is less than or equal to 30cm and greater than 20cm, the second distance range is less than or equal to 20cm and greater than 10cm, and the third distance range is less than or equal to 10 cm. And when the target distance is 12cm and is within a second distance range, the terminal equipment displays a distance dynamic prompt interface corresponding to the second distance range.
Through the optional implementation mode, aiming at the static state of the terminal equipment, because the terminal equipment and the user are stable in the static state, a smaller distance threshold value is set, a smaller distance range is formed, the eyes of the user are protected, and the terminal equipment is more fit with the actual use scene.
Further, the manner for detecting the motion state of the terminal device may include at least the following two manners:
the implementation mode is as follows: continuously detecting an included angle between the terminal equipment and the horizontal direction to obtain two target angles; if the first angle difference value of the two target angles is larger than the preset angle difference value, determining that the terminal equipment is in a moving state; and if the first angle difference value of the two target angles is smaller than or equal to the preset angle difference value, determining that the terminal equipment is in a static state.
It should be noted that the terminal device may detect an included angle between the terminal device and the horizontal direction through a built-in sensor to obtain two target angles, where the two target angles are respectively an included angle detected by the sensor at two adjacent moments. If the first angle difference value of the two target angles is greater than the preset angle difference value, that is, the angle difference value between the included angle at the current moment and the included angle at the previous moment is greater than the preset angle difference value, it can be said that the terminal device is in a moving state; if the first angle difference between the two target angles is smaller than or equal to the preset angle difference, that is, the angle difference between the included angle at the current moment and the included angle at the previous moment is smaller than or equal to the preset angle difference, it can be said that the terminal device is in a static state.
The built-in sensor may be a gravity sensor, an inclination sensor, a gyroscope, or the like, and the embodiment of the present invention is not limited.
For example, assume that the preset angle difference is 20 °. The terminal device detects that the included angle in the first second is 26.8 degrees, the included angle in the second is 54.6 degrees, the angle difference value between the first second and the second is 27.8 degrees and is more than 20 degrees, and then the terminal device is in a moving state in the second; the terminal device detects that the included angle is 41.9 degrees at the third second, the angle difference value between the second and the third second is 12.7 degrees and is smaller than 20 degrees, and then the terminal device is in a static state at the third second; the terminal device detects that the included angle is 60.9 degrees at the fourth second, the angle difference value between the third second and the fourth second is 19 degrees and is smaller than 20 degrees, and then the terminal device is in a static state at the fourth second; the terminal device detects that the included angle is 10.4 degrees at the fifth second, the angle difference between the fourth second and the fifth second is 50.5 degrees and is larger than 20 degrees, and then the terminal device is in a moving state at the fifth second.
Through the optional implementation mode, the terminal equipment can detect an included angle between the terminal equipment and the horizontal direction, and if the terminal equipment detects that the angle difference value between the included angle at the current moment and the included angle at the previous moment is larger than the preset angle difference value, the terminal equipment is in a moving state; and if the angle difference value between the included angle at the current moment and the included angle at the previous moment is smaller than or equal to the preset angle difference value, the terminal equipment is in a static state. Therefore, the motion state of the terminal equipment can be accurately judged through the included angle between the terminal equipment and the horizontal direction.
The implementation mode two is as follows: continuously detecting the position information of the terminal equipment to obtain two target position information; if the first distance difference value of the two pieces of target position information is larger than the preset distance difference value, determining that the terminal equipment is in a moving state; and if the first distance difference of the two pieces of target position information is smaller than or equal to the preset distance difference, determining that the terminal equipment is in a static state.
It should be noted that the terminal device may detect the position information of the terminal device by using a positioning method to obtain two target position information, where the two target angles are the position information detected by using the positioning method at two adjacent moments respectively. If the first distance difference between the two pieces of target position information is greater than the preset distance difference, that is, the distance difference between the position information at the current moment and the position information at the previous moment is greater than the preset distance difference, it can be said that the terminal device is in a moving state; if the first distance difference between the two pieces of target position information is smaller than or equal to the preset distance difference, that is, the distance difference between the position information at the current moment and the position information at the previous moment is smaller than or equal to the preset distance difference, it can be said that the terminal device is in a stationary state.
The positioning method comprises the following steps: at least one of Wireless Fidelity (WiFi) positioning, satellite positioning and base station positioning. The Satellite Positioning may be chinese BeiDou Navigation Satellite System (BDS) Positioning, Global Positioning System (GPS) Positioning, or other Positioning methods, and is not limited herein.
Illustratively, assume that the preset distance difference is 25 cm. When the terminal device detects that the position information at the first second is the position A, the position information at the second is the position B, and the distance difference value between the first second and the second is 40cm and is more than 25cm, the terminal device is in a moving state at the second; when the terminal device detects that the position information at the third second is the position C, the distance difference value between the second and the third second is 12cm and is smaller than 25cm, and then the terminal device is in a static state at the third second; when the terminal device detects that the position information at the fourth second is the position D, the distance difference value between the third second and the fourth second is 20cm and is smaller than 25cm, and then the terminal device is in a static state at the fourth second; and the terminal equipment detects that the position information at the fifth second is the position E, the distance difference between the fourth second and the fifth second is 75cm and is more than 25cm, and the terminal equipment is in a moving state at the fifth second.
Through the optional implementation mode, the terminal equipment can detect the position information of the terminal equipment, and if the terminal equipment detects that the distance difference between the position information at the current moment and the position information at the previous moment is greater than the preset distance difference, the terminal equipment is in a moving state; and if the distance difference between the position information at the current moment and the position information at the previous moment is smaller than or equal to the preset distance difference, the terminal equipment is in a static state. Therefore, the motion state of the terminal equipment can be accurately judged through the position information of the terminal equipment.
Further, after determining that the user of the terminal device is currently located on the target vehicle, the terminal device further includes: acquiring identity information of a user according to the identification information of the first wireless access point, wherein the identity information of the user at least comprises: a curriculum schedule, the curriculum schedule comprising: the time and place of each course; acquiring a class-taking place of a target class, wherein the class-taking time of the target class is closest to the current system time of a target vehicle; and when the target vehicle is detected to reach the getting-off place corresponding to the on-class place of the target course, outputting a second prompt message, wherein the second prompt message is used for prompting the user that the user has reached the on-class place of the target course.
It should be noted that the terminal device may obtain identity information of the user, where the identity information at least includes: a curriculum schedule; the curriculum schedule can include at least: the time of day of each course and the location of day of each course. At this time, the terminal device can sequence all the courses on the curriculum schedule according to the front-back sequence of the lesson time of each course; therefore, the terminal equipment can determine the target course corresponding to the lesson time closest to the current system time according to the sequencing result; the terminal equipment can detect whether the target vehicle reaches the get-off place corresponding to the on-class place of the target course or not according to the positioning method; if the current location has arrived, the terminal device may output a second prompt message to prompt the user that the current location of the target course has been reached and the user may get off the vehicle.
For example, it is assumed that the curriculum schedule of the user acquired by the terminal device includes four lessons, which are: course A, 10:00, site A; course B, 16:30, site B; course C, 14:10, site C; course D, 11:15, location D; the current system time is 11:02 and the current location is location D. Thus, the terminal equipment can sort the four courses according to the front and back sequence of the lesson time, and the sorting result is A → D → C → B; the terminal device determines that the closest class time is 11:15 according to the current system time, namely corresponding to the course D, and the target vehicle also arrives at the class-in place D corresponding to the course D, so that the terminal device can output a prompt message that the class-in place D which has arrived at the course D is cheered, and the user is ready to get off to get back.
Through the optional implementation mode, the terminal equipment can avoid the situation that the user uses the terminal equipment on the vehicle to cause the missing of the class time and the class place.
As an optional implementation manner, after detecting that the facial features of the user exist in the target image, the terminal device may further include: acquiring the age of a user according to the facial features of the user, and if the age of the user is smaller than a preset age, displaying a distance dynamic prompt interface corresponding to a target distance range when the target distance between the user and the terminal equipment is within the target distance range; and if the age of the user is greater than or equal to the preset age, displaying a text prompt message when the target distance between the user and the terminal equipment is within the target distance range.

It should be noted that the terminal device may obtain personal information of a user, and display N preset animation images matched with the user according to the personal information, so that the user can select from the N preset animation images; after the terminal device receives the touch operation of the user, the terminal device can obtain the target animation image selected by the user in response to the touch operation.

Through the optional implementation mode, the terminal equipment can display a part of prestored animation images according to personal information of a user, the user can select one animation image from the animation images to be displayed in the display screen, and the animation image can be replaced at any time. Therefore, the user is prompted by the favorite animation image of the user, the interest of the user can be attracted, the user is easy to accept, the output form of the prompting message is enriched, and the prompting effect is obvious.
As an optional implementation manner, the target animation image displayed by the terminal device on the distance indication area in the distance dynamic prompt interface may specifically include: acquiring a cartoon playing history of a user within a preset time length, acquiring a cartoon with the most playing times, and acquiring a plurality of animation images from the cartoon and displaying the animation images on a display screen for the user to select; after the terminal device receives the touch operation of the user, the terminal device can obtain the target animation image selected by the user in response to the touch operation.
It should be noted that the terminal device may obtain the animation play history within a period of time, and select the animation image in the animation with the largest play frequency for the user to select from; after the terminal device receives the touch operation of the user, the terminal device can obtain the target animation image selected by the user in response to the touch operation.
For example, assume that the preset duration is two weeks.
