Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is an electronic map page provided in the prior art. Referring to fig. 1, a toolbar is provided on the electronic map page, the toolbar may include buttons similar to "road condition", "navigation", "taxi taking", and "radius", and a plurality of radius options for the user to select are set under the sub-menu corresponding to the "radius" button, so as to set the radius of the viewed area. In a scenario where a user selects an area on an electronic map for viewing, the user may determine the size of the viewed area by selecting a radius option, and adjust the size of the viewed area by switching the radius option. And drawing a corresponding map area according to the radius selected by the user and presenting the map area to the user. For example, when the user switches to the larger radius option, the circular area in the page becomes larger, and when the user switches to the smaller radius option, the circular area in the page becomes smaller.
However, in the above method, the radius that the user can select is limited by the radius option provided by the toolbar, so that the flexibility in adjusting the size of the viewed area is poor, and the user's needs cannot be satisfied. In addition, the user may need to perform too many steps to adjust the viewing area to the optimal size, including opening the toolbar, first selecting a radius option, switching the radius option, closing the toolbar until the optimal size is adjusted, and so on. In addition, in the method, the toolbar needs to float on the electronic map, which affects the integrity of the map and also affects the user experience.
In order to solve the above problems, the present application provides a method for selecting an area on an electronic map according to an embodiment, and the method has sufficient flexibility for adjusting the size of the area, and completely abandons the idea of setting a radius option toolbar on the map, so that the user operation can be simplified, the integrity of map display is ensured, and the user experience is more friendly.
Fig. 2a and 2b are flow charts illustrating a method for selecting an area on an electronic map according to an exemplary embodiment of the present disclosure. As shown in fig. 2a and 2b, the method may include:
step 201, when a currently displayed page of a terminal device includes an electronic map, detecting a touch operation on the electronic map.
In the embodiment of the present application, the terminal device may be a wireless terminal or a wired terminal, and may be, for example, a mobile phone, a computer, a tablet computer, a personal digital assistant, a mobile internet device, a wearable device, an e-book reader, and the like.
The terminal device has a touch screen on which one or more soft keys, menus and other user interface objects can be displayed. A user may interact with the device by contacting the touch screen location corresponding to the user interface object with which the user wishes to interact. The touch screen may then detect and respond to a contact, i.e. a touch operation, on the touch screen. Different types of touch operations may correspond to different types of gestures, such as sliding, dragging, pressing, and the like. By means of touch operations and/or gestures, certain functions provided by applications in the terminal device may be activated or deactivated.
Fig. 3a and 3b show two exemplary pages of a terminal. As shown in fig. 3a, the page is a page entered by a user after starting the electronic map APP, such as a Baidu map, a Gade map, and the like, and the page includes the electronic map. As shown in fig. 3b, the page is a page of a non-electronic map APP such as a browser, 58 city APP, etc., and an area 301 dedicated to displaying an electronic map is provided in the page, and the electronic map is displayed only in the area.
When the currently displayed page of the terminal device includes the electronic map, if the user wants to interact with the electronic map, the user needs to touch the touch screen position corresponding to the electronic map, and the touch screen needs to continuously detect the touch operation of the user on the touch screen position corresponding to the electronic map.
In this embodiment, different types of touch operations are used to activate different functions, and a press operation is used to activate a function for selecting an area on a map.
In step 202, if the detected touch operation is a pressing operation, a pressing force of the pressing operation is obtained.
When the touch screen detects touch operation on the electronic map, the operation type is judged, and if the operation type is pressing operation, the pressing force degree of the pressing operation is acquired. The pressing force degree can be acquired through a pressure detection device or a pressure acquisition device, and the pressure detection device or the pressure acquisition device can be a pressure sensor. When a finger of a user presses on the touch screen, the pressure sensor acquires pressing pressure data in real time.
In this embodiment, the degree of pressing may be represented by an actual value of the degree of pressing, or may be converted into a force degree coefficient, and the force degree coefficient may be used to represent the degree of pressing.
In addition, when the pressing operation is detected, in order to avoid a wrong operation, that is, to avoid a pressing operation not used for selecting an area on the map from being mistaken for a pressing operation used for selecting an area on the map, before the step 203 of specifying, it may be determined whether the detected pressing operation satisfies a preset condition.
As an embodiment, the preset condition may be that the pressing force of the pressing operation reaches a preset lower limit. That is, it is determined whether the pressing force degree of the pressing operation reaches a preset lower limit of the pressure value. The lower limit of the pressure value is a preset pressure threshold value which is used as the minimum pressure value required by selecting an area on the electronic map through pressing operation. The specific numerical value of the lower limit value of the pressure value is not limited in the embodiment of the application, and may be larger than the pressure value generated when the mobile terminal display screen performs the click operation, and when the user wants to select an area on the electronic map, the degree of the pressure needs to be increased appropriately to distinguish from other click operations.
As another embodiment, since the touch operation on the touch screen is usually instantaneous touch, the preset condition may be that the pressing duration of the pressing operation reaches a preset pressing duration to be distinguished from other touch operations of the user on the electronic map. The specific value of the preset pressing time is not limited in the embodiment of the present application, and may be 200ms, for example.
As another embodiment, the pressing operation needs to satisfy both the lower limit value of the pressure value and the preset pressing duration, that is, when the pressing force of the pressing operation exceeds the lower limit value of the preset pressure value and the pressing duration exceeds the preset pressing duration, it is determined that the pressing operation is an operation for selecting an area on the electronic map, and at this time, step 203 is executed.
Step 203, determining a target radius corresponding to the pressing strength at the current moment according to a preset relationship between the pressing strength and the area radius.
Regarding the preset relationship between the degree of pressing and the radius of the area:
in one embodiment, the pressing force does not reach the preset upper limit FOn the upper partThe pressing force is a function of the radius of the area, such as a direct ratio. For example, the relationship between the pressing force F and the region radius R is R ═ F (F/F)On the upper part)RMAXWherein R isMAXA preset maximum zone radius. When the pressing force exceeds (including reaches) a preset upper limit, the area radius will not change any more, i.e. R ═ RMAX。
In another embodiment, the pressing force does not reach the preset upper limit FOn the upper partThe pressing force is a function of the radius of the area, such as a direct ratio. When the pressing force exceeds (including reaches) the preset upper limit and the pressing operation continues to exist, the area radius will increase at the preset speed until the pressing operation disappears.
Of course, the pressing force and the area radius may have other functional relationships, such as a quadratic function, so as to achieve that the area radius continuously increases as the pressing force increases until the pressing force reaches a preset upper limit, and the area radius increases to the maximum area radius or continues to increase at a preset speed.
In addition, as shown in the following table, the pressing force degree and the area radius may be associated with each other in intervals, for example, the pressing force degree is F1To F2When in range, the radius of the region is R1Degree of pressing at F2To F3Within the range ofWhen the radius of the region is R2And repeating the steps until the pressing force reaches the preset upper limit, and increasing the area radius to the maximum area radius or continuously increasing at the preset speed.
| Degree of compression/F | Radius of area/R |
| F1～F2 | R1 |
| F2～F3 | R2 |
| …… | …… |
| Fn～Fn+1 | Rn |
And 204, displaying a target area determined according to the pressing position coordinates and the target radius in the electronic map.
When the touch screen detects touch operation on the screen, the touch screen detects two-dimensional coordinates corresponding to the touch point, and the pressing operation is the pressing position coordinates.
As an implementation manner, a circular area on the electronic map, that is, the target area may be determined by taking the coordinate of the pressing position as a center of a circle and taking the target radius determined according to the degree of pressing in step 203 as a radius. The position of the target area depends on the pressing position of the user on the electronic map, and the size depends on the pressing degree of the pressing operation of the user.
In the concrete implementation:
firstly, obtaining the longitude and latitude information of a target according to the coordinates of the pressing position and the radius of the target. The target latitude and longitude information is used for determining geographic information of the target area, and if the geographic coordinates are determined by the latitude and longitude data, the geographic information of the target area is a set of geographic coordinates determined according to all the latitude and longitude data. Wherein the standard geographic information having global common attributes includes, but is not limited to, a place name, global uniform coordinates, global GPS coordinates. In addition, standard geographic information with non-public attributes can be contained, such as geographic position marks attached to the electronic map APP.
And then, generating a target area map layer according to the target longitude and latitude information. In order to enable the generated target area layer to be adaptive to the display size of the electronic map on the screen, during specific implementation, a target scale is determined according to the display size of the electronic map on the screen of the terminal equipment and the actual size of the target area; and generating a target area layer according to the target scale and the target longitude and latitude information so as to enable the generated target area layer and the display size.
It should be noted that the case that the display size of the target area layer and the display size of the electronic map on the screen are not adapted includes: firstly, as shown in fig. 4a, the area occupied by the target area map layer on the electronic map is small, and the target area is the area that the user really wants to view, so that when the display range is small, the view is affected, and the display space is wasted. Secondly, as shown in fig. 4b, the target area layer exceeds the display size of the electronic map on the screen, which results in incomplete display of the target area layer.
And finally, replacing the current map layer in the electronic map by using the target area map layer. The electronic map is pre-established and maintained with a dictionary for storing data used for generating layers. When new longitude and latitude information is generated due to a pressing operation of a user, old layer data is removed from the dictionary, and new layer data obtained according to the longitude and latitude information is stored in the dictionary so as to be used for creating a new layer. In addition, since only one area layer may exist at each time point on the electronic map, when the electronic map needs to display a new area layer due to a pressing operation of a user, the old area layer on the electronic map needs to be removed, and then the new area layer, that is, the target area layer needs to be added.
It can be seen from the foregoing embodiments that the present application provides a method for selecting an area on an electronic map, where the method detects a touch operation on the electronic map when a page currently displayed by a terminal device includes the electronic map; if the detected touch operation is a pressing operation, acquiring the pressing pressure degree of the pressing operation; determining a target radius corresponding to the pressing degree at the current moment according to a preset relation between the pressing degree and the area radius; and finally, displaying the target area determined according to the pressing position coordinate and the target radius in the electronic map. By the method, the size of the target area can be adjusted by changing the degree of pressing force, and the adjustment is not performed according to the fixed radius option, so that the method has sufficient flexibility. In addition, the visible area of the electronic map is increased because a toolbar does not need to be additionally arranged on the map.
On the basis of the above embodiment, the method of the present application further includes:
and step 205, when the pressing force degree changes, dynamically updating the displayed target area according to the changed target area.
As can be seen from step 203, as the degree of pressing increases, the target radius determined from the degree of pressing increases, and the target area increases. The displayed target area is dynamically updated according to the changed target area, via step 205. Specifically, when the pressing force changes, the target radius, that is, the changed target radius is newly determined based on the changed pressing force, a new target area is determined based on the pressing position coordinates and the new target radius, and the new target area is displayed on the electronic map. The above process is executed once when the detected pressing force changes, so as to achieve the effect of dynamically updating the target area displayed in the electronic map.
And the target radius changes along with the pressing force according to the preset relation between the area radius and the pressing force. Under the condition that the degree of pressing does not exceed a preset upper limit, the target radius changes according to the preset relation along with the change of the degree of pressing; when the pressing degree exceeds a preset upper limit, taking a preset maximum radius as a target radius; or, when the pressing force exceeds a preset upper limit and the pressing operation continues to exist at the current pressing force, the target radius is increased at a preset speed until the pressing operation disappears.
Fig. 5a, 5b and 5c show a process in which the target area displayed in the electronic map gradually increases as the degree of pressing force increases.
Of course, when the acquired pressing force becomes smaller, the target area also becomes smaller accordingly. On the electronic map, the implementation process of dynamically decreasing the target area and the implementation process of dynamically increasing the target area are based on the same concept, and reference may be made to the above embodiments, which are not described herein again.
In the existing method described in the background section of the present application, a user needs to select one of the radius options in the toolbar first, and after determining, the size of the corresponding area can be visually seen on the electronic map. And so on until the optimal size is found. It can be seen that, in the existing method, not only are more user operations involved, but also the user cannot see the corresponding area size while selecting the radius, but also can see the area size after a certain time delay, which results in low adjustment efficiency and poor user experience.
Compared with the prior art, according to the method, the size change process of the target area on the electronic map is the visual reflection of the size change process of the pressing force degree, so that the user can establish the relation between the pressing force degree and the target area in the mind and sea carelessly, and further know how to adjust the pressing force degree of the finger on the screen, so that the target area can be adjusted to the optimal size. Therefore, the method can be realized through simple interactive operation, the user operation is greatly simplified, and the method has higher adjusting efficiency and friendly user experience.
In addition, the map display device has sufficient flexibility because the adjustment is not performed according to a fixed radius option, and the visible area of the map can be increased because a toolbar does not need to be added on the map.
On the basis of the above embodiment, the method of the present application further includes:
step 206, monitoring whether the pressing operation is changed into a predetermined operation.
And step 207, when the change of the pressing operation is monitored to be a preset operation, keeping the currently displayed target area in the electronic map unchanged, and stopping obtaining the pressing force.
The change of the pressing operation to the predetermined operation means that the predetermined operation and the pressing operation are seamlessly continued. The predetermined operation may be understood as an operation for closing a flow of selecting an area on the electronic map, and may be, for example, a sliding operation upward.
In one scenario, after the user finds the optimal size of the area by adjusting the pressing force, if the pressing operation is cancelled immediately, the pressing force obtained by the pressure detection device is reduced to 0 instantly because the pressure detection device does not stop working at this time, and the target area with the optimal size is reduced instantly because the process of selecting the area provided by the present application is continued, so that the user cannot view the target area.
Therefore, in order to avoid such a phenomenon, after finding a target area with an optimal size, a user modifies the pressing operation into a predetermined operation, so that the predetermined operation and the pressing operation are seamlessly connected, when the predetermined operation is detected by the touch screen, the pressure detection device can be closed to stop obtaining the pressing force, and further, the flow of selecting an area on the electronic map can be closed, and meanwhile, the currently displayed target area in the electronic map is kept unchanged, and the currently displayed target area is the area which the user wants to view.
As can be seen from the foregoing embodiments, the present application provides a method for selecting an area on an electronic map, where in the method, when a page currently displayed by a terminal device includes the electronic map, a touch operation on the electronic map is detected; if the detected touch operation is a pressing operation, acquiring the pressing pressure degree of the pressing operation; determining a target radius corresponding to the pressing degree at the current moment according to a preset relation between the pressing degree and the area radius; and finally, displaying a target area determined according to the pressing position coordinate and the target radius in the electronic map. Through the method, the size of the target area can be adjusted by changing the pressing degree, and the adjustment is not carried out according to a fixed radius option, so that the method has sufficient flexibility. In addition, the method can be realized through simple interactive operation, and a toolbar does not need to be additionally arranged on the map, so that the visual area of the electronic map can be increased, and meanwhile, the user operation is greatly simplified, and the user experience is more friendly.
According to the method for selecting the area on the electronic map, the embodiment of the application also provides a device for selecting the area on the electronic map.
