[0033] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] Figure 1 This is a flowchart of the electronic map POI search and interaction method in an embodiment of the present invention. See [link / reference]. Figure 1 The electronic map POI search and interaction method of this embodiment includes the following steps:

[0035] Step S110: Receive the user's selection of a specified POI on the electronic map, and use the POI selected by the user as the center point of the POI.

[0036] Step S120: Obtain the keywords input by the user, search according to the keywords, and obtain one or more POIs that correspond to the keywords and belong to the distribution range of the POI center points;

[0037] Step S130 outputs one or more POIs obtained from the search and caches the keywords for use in subsequent searches.

[0038] Depend on Figure 1 As shown, the electronic map POI search interaction method in this embodiment receives the user's selection of a specified POI on the electronic map, uses the user-selected POI as the POI center point, obtains the keywords entered by the user, performs a search based on the keywords, and obtains one or more POIs that correspond to the keywords and belong to the distribution range of the POI center point; it outputs the one or more POIs obtained from the search and caches the keywords for subsequent searches. Thus, when it is necessary to change the center point to continue searching, only the center point needs to be reselected once. At the same time, it also eliminates the step of re-entering or selecting keywords, simplifying the process and improving the user interaction experience.

[0039] To address the cumbersome process of finding Points of Interest (POIs) related to a specific keyword near a location on a map, this invention provides an improved electronic map POI search and interaction method. The implementation of this method will be highlighted below using a specific application scenario.

[0040] During a search process, the process begins by receiving the user's selection of a specified POI on the electronic map. The selected POI is used as the POI center point. Next, the user's input keywords are obtained, and a search is performed based on the keywords to obtain one or more POIs that correspond to the keywords and belong to the distribution range of the POI center point. After obtaining one or more POIs, the search results are output, and the keywords are cached for use in subsequent searches.

[0041] Considering the need for users to select a center point and then change it to continue searching, this embodiment of the invention detects whether the POI center point has changed. When a change in the POI center point is detected, the cached keywords used in the previous search are used as the keywords for the current search. A search is then performed based on these keywords to obtain one or more POIs that correspond to the keywords and fall within the distribution range of the changed POI center points. Therefore, when a user changes the POI center point and continues searching, they do not need to re-enter or select keywords, simplifying the search process and improving the user experience.

[0042] There are two ways to detect whether the POI center point has changed. One way is to determine whether the user clicks on any location on the electronic map within a preset time period after selecting the POI center point. If so, the center point is determined to have changed.

[0043] For example, during a search, a user selects any location on an electronic map, denoted as point A, and enters or selects keywords. This embodiment of the invention obtains the user's selected center point and the entered keywords. After searching based on the keywords, it finds multiple Points of Interest (POIs) near center point A that are related to the keywords and outputs them for the user to view. This process takes 1 minute. If the user is not satisfied with the search results, they may need to change the center point and continue searching. In this case, the user clicks on any location on the electronic map again, denoted as point C. If the system detects that the user clicks on different locations on the electronic map twice within a predetermined time period, such as 1 minute, it determines that the POI center point has changed.

[0044] Another approach is to determine whether the user has moved the previously selected POI center point to any other location within a preset time period after selecting the center point. If the user has moved the previously selected POI center point to any other location within the preset time period, then the POI center point has been determined to have changed. Compared to the previous approach, this implementation can capture the user's movement on the electronic map without requiring a second click to select the center point. In practical applications, both implementation methods can be set as needed, and this embodiment of the invention does not impose any restrictions on this.

[0045] Therefore, when a user clicks on any point on the map (hereinafter referred to as point C) or moves the previous center point to any point (hereinafter referred to as point C), point C will be used as the new center point of the POI.

[0046] After determining that the POI center point has changed, this embodiment uses the cached keywords from the previous search as the keywords for the current search. The search is performed based on the keywords for the current search to obtain one or more POIs that correspond to the keywords for the current search and belong to the distribution range of the changed POI center points.

[0047] After obtaining the search results, that is, one or more POIs that correspond to the search keywords and belong to the distribution range of the POI center point, the embodiments of the present invention output the search results. Specifically, outputting one or more POIs obtained from the search includes: generating a shadow layer containing a circular distribution range with the POI center point as the center and a preset distance threshold as the radius, and outputting the shadow layer over the original layer of the electronic map.

[0048] See Figure 2 210 represents the original layer, and 220 represents the generated shadow layer. Figure 2 As shown, the shadow layer contains a circular distribution range, with the center of the circular distribution range being the center point and the radius being a preset distance threshold, such as 1.5 kilometers.

[0049] When multiple POIs are obtained through a search, in this embodiment of the invention, the multiple POIs are consecutively numbered according to a preset rule, and their respective numbers are highlighted within a circular distribution area. See also Figure 2 The diagram illustrates POIs numbered 1-10. The default rules here are, for example, their distance from the center point.

[0050] The highlighting here, for example, involves highlighting the individual numbers of one or more POIs with a different color than the center point of the POI. For example... Figure 2As shown, the color of the center point 2201 is lighter than the colors of the multiple POIs corresponding to the keywords obtained from the search, thus displaying the search results clearly and intuitively, making them easy to understand at a glance.

[0051] Belonging to the same inventive concept as the aforementioned method embodiments, this invention also provides an electronic map POI search and interaction device, such as... Figure 3 As shown, the electronic map POI search interactive device 300 includes:

[0052] The center point determination unit 310 is adapted to receive the user's selection of a specified POI on the electronic map and use the POI selected by the user as the center point of the POI.

[0053] Search unit 320 is adapted to acquire keywords input by the user and perform a search based on the keywords to obtain one or more POIs that correspond to the keywords and belong to the distribution range of the POI center points;

[0054] The output unit 330 is adapted to output one or more POIs obtained from the search and cache the keywords for subsequent searches.

[0055] In one embodiment of the present invention, the device 300 further includes: a center point changing unit, adapted to detect whether the center point of the POI has changed, and when the center point of the POI is detected to have changed, using the cached keywords used in the previous search as the keywords for the current search, and performing a search based on the keywords for the current search to obtain one or more POIs that correspond to the keywords for the current search and belong to the distribution range of the changed POI center points.

[0056] In one embodiment of the present invention, the center point changing unit is specifically adapted to determine that the POI center point has changed if the user clicks on any location point on the electronic map within a preset time period after selecting the POI center point.

[0057] In one embodiment of the present invention, the center point changing unit is specifically adapted to determine that the POI center point has changed if the user moves the previously selected POI center point to any location point within a preset time period after selecting the POI center point.

[0058] In one embodiment of the present invention, the output unit is specifically adapted to generate a shadow layer containing a circular distribution range with the center point of the POI as the center and a preset distance threshold as the radius, and output the shadow layer over the original layer of the electronic map.

[0059] In one embodiment of the present invention, the output unit is specifically adapted to continuously number one or more POIs obtained from the search according to a preset rule and highlight the corresponding number of one or more POIs within the circular distribution range.

[0060] In one embodiment of the present invention, the output unit is specifically adapted to highlight the number corresponding to one or more POIs with a display color different from that of the center point of the POI.

[0061] In summary, during the information search process based on electronic maps, when it is necessary to change the center point to continue the search, users only need to click once or move the previously selected center point once, which reduces the steps of re-entering or selecting keywords and improves the user experience.
