It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the steps as sequential processing, many of the steps may be performed in parallel, concurrently, or simultaneously. Additionally, the order of steps may be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

FIG. 1 is a schematic flowchart of a prompting method for a mobile terminal provided by an embodiment of the present invention. The method can be executed by a prompting device of the mobile terminal, wherein the device can be implemented by software and/or hardware, and generally can be integrated in the mobile terminal. As shown in Figure 1, the method includes:

Step 101, when it is detected that the user is using the mobile terminal in a moving state, determine the traveling direction of the user.

Exemplarily, the mobile terminal in this embodiment may specifically be devices such as mobile phones, smart watches, tablet computers, game consoles, personal digital assistants, and digital multimedia players.

In this embodiment, the built-in gyroscope and other sensors of the mobile terminal can be used to detect whether the mobile terminal is in a moving state, or the built-in Global Positioning System (Global Positioning System, GPS) or positioning technologies such as network positioning and base station positioning can be used to detect whether the mobile terminal is in a moving state. Detect whether the mobile terminal is in a moving state. Preferably, the moving state in this embodiment may specifically refer to the natural moving state, which corresponds to the user's human body movement state such as walking or running, and excludes that the mobile terminal is in a state of being in a state caused by the user taking a bus or a taxi. fast moving state.

Exemplarily, using the mobile terminal in this embodiment may specifically include viewing a screen of the mobile terminal. Whether the user is using the mobile terminal can be determined by detecting whether the user is watching the screen of the mobile terminal. Among them, there are many ways to judge. For example, from the perspective of the screen, it can be determined whether the user is watching the screen by judging whether the screen is in the display state; Whether the user is looking at the screen or not is determined by whether the user's eyes are directly facing the screen. Therefore, detecting that the user is using the mobile terminal in the mobile state of the mobile terminal may specifically include: judging whether the screen of the mobile terminal is in the display state in the mobile state of the mobile terminal, and if so, detecting that the user is in the mobile state of the mobile terminal Use a mobile terminal; or, judge whether human eyes or faces appear in front of the screen of the mobile terminal through iris recognition or face recognition in the mobile state of the mobile terminal, and if so, detect that the user is using the mobile terminal in the mobile state. the mobile terminal. It can be understood that there may be many other specific manners for judging whether the user is using the mobile terminal, and the above several manners are only illustrative illustrations, which are not limited in this embodiment. In order to improve the accuracy of the judgment, a combination of two or more judgment methods can also be used, for example, to judge whether the screen of the mobile terminal is in the display state under the mobile state of the mobile terminal, and if so, through iris recognition or human Face recognition determines whether human eyes or faces appear in front of the screen of the mobile terminal, and if so, it is detected that the user is using the mobile terminal while the mobile terminal is moving.

Exemplarily, the above-mentioned sensor data or positioning data acquired when detecting the moving state of the mobile terminal can be analyzed and counted to obtain the moving rule of the mobile terminal, and then determine the traveling direction of the user.

Preferably, determining the traveling direction of the user may specifically include: recording a moving track of the mobile terminal, and determining the traveling direction of the user according to the moving track. For example, when the mobile terminal is detected to be in a moving state, the GPS can be controlled to start recording the mobile terminal’s trajectory, analyze the shape and direction of the trajectory, determine the trend of the user’s travel, and then determine the user’s travel direction.

Step 102, determining the target road corresponding to the mobile terminal in the electronic map.

Exemplarily, the electronic map can be a map application program loaded in a mobile terminal, such as Baidu map and Gaode map, etc.; it can also be a local map stored in the mobile terminal; it can also be accessed through a browser or other methods network map etc. This embodiment does not specifically limit the type of the electronic map.

Exemplarily, the target road corresponding to the mobile terminal may specifically be a road near map coordinates corresponding to the location of the mobile terminal in the electronic map. There may be one or more target roads, which are specifically determined by the distribution of roads at the location of the mobile terminal. Preferably, when there are multiple roads near the mobile terminal, filter conditions can be set to filter out a suitable target road. For example, this step may include: obtaining the current location of the mobile terminal, determining the coordinates corresponding to the current location in the electronic map according to the current location, and determining the corresponding preset range (such as within a radius of 10 meters) with the coordinates as the center. Include candidate roads, calculate the length of the vertical segment from the coordinates to each candidate road, and determine the candidate road whose length of the vertical segment gradually becomes shorter as the target road.

Step 103, when the angle between the traveling direction and the extending direction of the target road is greater than a preset angle threshold, control the mobile terminal to give relevant safety reminders.

Exemplarily, the preset angle threshold can be set by default by the system, or can be set by the user according to his own exercise habits such as walking or running. For example, the preset angle threshold can be set to 30 degrees or 60 degrees or the like.

For example, when the angle between the direction of travel and the extension direction of the target road is greater than the preset angle threshold, it means that the user's travel direction deviates from the target road, and the user is probably crossing the road. Timely and effective reminders and reminders of the safety situation are required. There may be danger ahead of the user, which requires suspension of use of the mobile terminal.

Exemplarily, there may be many manners for providing relevant security prompts, which are not specifically limited in this embodiment. For example, the mobile terminal can be controlled to play warning sounds, play prompt voices, light up warning lights and vibrate, etc.; it can also control the mobile terminal to display prompt text on the screen; it can also control the mobile terminal to turn off the screen, so as to prevent users from continuing to use the mobile terminal the goal of.

The mobile terminal prompting method provided by the embodiment of the present invention detects that the user is using the mobile terminal while the mobile terminal is moving, determines the user's traveling direction, and determines the target road corresponding to the mobile terminal in the electronic map. When the angle between the extension direction of the target road is greater than the preset angle threshold, it means that the user's traveling direction deviates from the target road, and it is likely to cross the road while using a mobile terminal, which may pose a safety hazard. Then control the mobile terminal to give relevant safety reminders. To provide timely and effective reminders to users. By adopting the above technical solution, when it is detected that the user may use the mobile terminal while walking, a reasonable prompt is given for the safety situation, which enriches the prompt function of the mobile terminal.

Fig. 2 is a schematic flowchart of another prompt method for a mobile terminal provided by an embodiment of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiment. The corresponding target road" is optimized as follows: obtain the current location of the mobile terminal; determine the target road within the corresponding preset range in the electronic map according to the current location.

Further, determining the target road within the corresponding preset range in the electronic map according to the current position may also specifically include: determining the coordinates corresponding to the current position in the electronic map as the center of the circle according to the current position, and determining the corresponding road according to the center of the circle and the preset radius. The preset range is used to determine the target road within the determined preset range.

Correspondingly, the method of this embodiment includes the following steps:

Step 201, when it is detected that the user is using the mobile terminal in a moving state of the mobile terminal, determine the traveling direction of the user.

Step 202, acquiring the current location of the mobile terminal.

Exemplarily, the location of the mobile terminal can be obtained in real time through GPS, and the obtained location at the current moment can be used as the current location of the mobile terminal.

Step 203: Determine the coordinates corresponding to the current position in the electronic map as the center of the circle according to the current position.

Step 204: Determine the corresponding preset range according to the center of the circle and the preset radius.

Exemplarily, the preset radius can be set by the system, or set by the user according to his own exercise habits such as walking or running. In addition, the preset radius can also be determined according to the moving speed of the mobile terminal. When the moving speed is fast, a larger radius can be determined so that the preset range is large enough to cover roads near the user. It can be understood that, when a part of a road is included in the preset range, it can be considered that the preset range has covered the road.

Step 205, determine the target road from the determined preset range.

Exemplarily, when only one road is included in the preset range, the road is determined as the target road; when multiple roads are included in the preset range, the multiple roads can be recorded as multiple candidate roads, and the center of the circle is calculated separately The length of the vertical line segment to each candidate road, and the candidate road whose length of the corresponding vertical line segment gradually becomes shorter is determined as the target road. It can be understood that when the length of the vertical line segment from the coordinates corresponding to the current position of the mobile terminal in the electronic map to a certain road gradually becomes shorter as the user continues to advance, it means that the user is gradually approaching the road, and it is likely that the user is about to This road is crossed, so this road can be determined as the target road.

Step 206, when the angle between the traveling direction and the extending direction of the target road is greater than a preset angle threshold, control the mobile terminal to give relevant safety reminders.

The embodiment of the present invention refines the process of determining the target road, and can accurately determine the target road, so as to more accurately determine whether the user is about to or is crossing the road, enhance the accuracy of safety prompts, and prevent the occurrence of false prompts.

Fig. 3 is a schematic flowchart of another prompting method for a mobile terminal provided by an embodiment of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiment. In this embodiment, if there are multiple target roads, the The step "when the angle between the direction of travel and the extension direction of the target road is greater than the preset angle threshold, control the mobile terminal to give relevant safety reminders" is optimized as follows: determine the intersection of multiple target roads; When the distance of the intersection gradually decreases, determine the included angle between the traveling direction and the extension direction of each of the multiple target roads; when any included angle is greater than a preset angle threshold, control the mobile terminal to give relevant safety reminders.

Correspondingly, the method of this embodiment includes the following steps:

Step 301, when it is detected that the user is using the mobile terminal in a moving state of the mobile terminal, determine the traveling direction of the user.

Step 302, determining multiple target roads corresponding to the mobile terminal in the electronic map.

Exemplarily, when there are multiple target roads, the user is likely to be at an intersection. At this time, the direction of the road is relatively complicated, and further determination needs to be made through subsequent steps.

Step 303, determine the intersection of multiple target roads.

It is understandable that if multiple target roads do not have intersections, it can be explained that these roads are parallel roads, and any one of the roads can be selected for subsequent judgments; it is also possible that the user is far away from the intersection. At this time, the distance from the user can be selected The nearest road for follow-up determination.

Step 304, when the distance between the location of the mobile terminal and the intersection gradually decreases, determine the angle between the traveling direction and the extension direction of each of the multiple target roads.

It can be understood that when the distance between the location of the mobile terminal and the intersection gradually decreases, it means that the user may be about to or is crossing a certain road, and the distance between the traveling direction and the extension direction of each of the multiple target roads can be determined. Angle; when the distance between the location of the mobile terminal and the intersection gradually increases, it means that the user has walked to the opposite side of the road, or continues to move along a certain road, and no subsequent judgment is required at this time.

Step 305, when any included angle is greater than a preset angle threshold, control the mobile terminal to give relevant safety prompts.

In this step, each included angle can be judged separately, and when a certain included angle is greater than a preset angle threshold, the mobile terminal is controlled to give a relevant safety prompt.

The prompting method of the mobile terminal provided by the embodiment of the present invention takes into account the situation of the intersection, can more accurately determine whether the user is about to or is crossing the road, enhances the accuracy of safety prompts, and prevents the occurrence of false prompts.

Step 402: Detect whether the mobile terminal is in a moving state through the gyroscope sensor, if yes, execute step 403; otherwise, repeatedly execute step 402.

Step 403, recording the movement track of the mobile terminal through the GPS sensor.

Step 404: Determine the user's traveling direction according to the movement track, and determine the included angle between the traveling direction and the extending direction of the target road corresponding to the location of the mobile terminal in the built-in map.

Step 405 , judging whether the included angle is greater than the preset angle threshold, if yes, execute step 406 ; otherwise, return to execute step 404 .

It can be understood that, if the mobile terminal is in a moving state, the GPS will record the moving track of the mobile terminal in real time, and when step 404 is executed again, the moving track has been updated.

Step 406, determine that the user is crossing the road, and control the screen of the mobile terminal to display prompt text.

Exemplarily, the prompt text may prompt the user to pay attention to vehicle safety while crossing the road.
