Description of the invention: [Technical field to which the invention pertains] A method for searching for a point of interest when navigating, in particular, a method for planning a search range of a free shape on a map displayed by a user on a navigation device. [Prior Art] Referring to FIG. 1A and FIG. 1B simultaneously, it is a schematic diagram of searching for a point of interest when the armature device performs a navigation operation in the prior art. The user inputs a search distance using the navigation device 100, and the reference point 110 used for the search distance is generally the position of the navigation device 1 itself. Searching for the same type of distance data of 5 km, 1 km, 500 m, etc. As shown in Figure 1, the search range is up to 1 km and the minimum is 1 km. The navigation device 1〇〇 will display the map to which the reference point 11〇 belongs and mark the position of the reference point 110. After that, the navigation device 1〇〇 is centered on the reference point 11〇, and each search distance is a radius, and a circular or circular search range 120a is planned on the map, and the interest points of the search range of 12〇a are displayed. 1〇1, such as attractions, gas stations, restaurants and other related information. Users can refer to this information to go to more interesting places. However, the prior art has a more perfect feature, that is, the navigation method used by the navigation device has only a single search method to find a point of interest, and no other search method is provided, and the shape of the search range is limited, only Round. If the user only needs to find the point of interest of the navigation device in the direction of the designated location, or only look for the navigation point | the travel point, the front (right side, left side of 201017128) points of interest. Navigation method to meet the actual navigation method and mode of the user. In view of this, the search solution according to the user input according to the present invention == is to provide a sharp guide that is applicable to various navigation devices. Fang = listening to the search for points of interest, in order to solve the above-mentioned method problems, too exposed - the scope of interest search range:: the technical means provided by Jin is released, the navigation device shows 1 navigation; t method, health - navigation Install ® * Map for navigation. In this method, the navigation device first receives a range of data to combine the map and the range of data, and the user can use the touch panel of the navigation device: the circumference: the closed area or the guide_the plurality of heart shapes: the area =, the user chooses from - as a closed area, and then integrates the configuration of the closed area on the map to form 笳]^ = out of the data. After that, the slave device matches: within the range of consumption to >, a point of interest data, the point of interest data is the geographic location and the material of interest ^. Finally, the navigation device displays the point of interest data within the search range. The present invention has the former The effect that technology can't achieve: - The navigation range of the interest point of the navigation device is not limited to a circle. ^This way, according to its own needs, it can be searched in the map domain to find what it really wants to know. Interest point information. First, when the location data is the location of the navigation device, when the navigation device navigates and shifts, the search for the interest point can be searched for its specific direction, such as the right side and the left side of the navigation device. Or a fan-shaped range in front is not limited to the search range of the circle. This method is more practical for the navigation device and the user, and the navigation device does not display irrelevant points of interest data, thereby reducing the burden of hardware computing materials. The displayed point of interest data is necessarily required by the user. [Embodiment] In order to further improve the end point, structural features and functions of the present invention

This method is applied to a navigation device. Here, we set the navigation device 100 to have a Global Positioning System (GPS). Please refer to the device block diagram of FIG. 3 for easy understanding. The flow of the method is as follows: The navigation device first receives a location data to display a map to which the location data belongs (step S110). In this step, the location data may be one of the following types: First, as shown in FIG. 4 With the general navigation device ι〇〇 input the designated location 201 (the cross mark of the towel in Figure 4), the user passes the touch module of the navigation device or the touch screen 17() (the control module 13 〇 The module 14G is combined to drive the designated address, coordinate bedding or area name of the designated place 2 () 1 . The designated address is “10th Floor, No. 436, Chengyi 1st Road, Qianjin District, Kaohsiung City”; the coordinates such as latitude and longitude “North latitude 24, Π 59.0393′ East longitude 12〇, 38, 12.861”; the name of the area is like “Taiwan 201017128 Nanxian Xinshi Township” . At this time, the navigation device 100 introduces the specified address, coordinate data or region name input by the user into the global positioning system 150, and the computing module 151 matches the location data to the map database 152, and extracts the map to which the location data belongs. Finally, the map is displayed via the touch screen 170 (or the display module 140). Second, as shown in Fig. 5, the user sets the position data to the position 202 of the navigation device 100 (the triangular mark shown in Fig. 5). At this time, the touch screen 170 (or the display module 140) displays the map to which the location 202 of the navigation device 100 belongs. Third, as shown in Fig. 6, the location data input by the user includes the location 202 of the navigation device 100 and an address specified by one of the external inputs of the user (the aforementioned designated location 201). At this time, the map displayed by the touch screen 170 is a geographical icon between the location 202 of the navigation device 100 and the designated location 201. The G navigation device 100 receives a range of data (step S120). In this step, the range data is the range in which the navigation device 100 wants to perform a search in the previously displayed map. When the navigation device 100 calculates the range data, it is necessary to first obtain a closed area 205 input by the user. The closed area 205 has at least two input modes: First, please refer to FIG. 7A and FIG. 7B in sequence, and the user draws the closed area 205 of the corresponding map by using the touch module 130 or the touch screen 170 of the navigation device 100. The navigation device 100 analyzes the touch screen 170 continuously to touch the 201017128 touch position to form a continuous line segment 204. The continuous line can be displayed through the touch screen 170 or the display module for user reference. Then, the navigation device 100 generates a closed area 205 by judging that the current touch position of the touch screen 重叠0 overlaps any one of the continuous line segments: a segment or any point, and the closed line segment is formed as an outer edge. The touch screen 170 will display the creation of the continuous line segment 204 and the formation of the enclosed area 205 for the user to understand the closed area 205 drawn by the user. " Second, as shown in FIG. 3, the navigation device 100 needs to store a plurality of closed areas 205 of different shapes in its own memory 180, and such closed areas 205 can list texts or display graphics. For the user's reference. The navigation device 100 first receives a shape selection command input by the user via the touch screen 170. The shape selection instruction has two forms, one of which commands the navigation device to display the graphic of the closed area 205, and the user selects one of them; the other, the shape selection instruction is a text command 'containing the required closed area. 205 name. Next, the navigation device 100 matches the shape selection command with the previously stored closed area 205 to output a closed area 205 ′ matching the shape selection command to display the shape of the closed area 2〇5 through the touch screen. Thereafter, the navigation device 100 receives an adjustment command to adjust the shape of the enclosed area 205 and the arrangement of the enclosed area 2〇5 on the map. As shown in Fig. 8, the user uses the stylus to drag the position of the closed area 2〇5 on the map, and reduces, enlarges and rotates the closed area 205, and even more, 201017128, the shape of the closed area 205 is modified. Alternatively, the adjustment command, the arrangement position, and the shape of the closed area 205 are input through the control panel 160 of the navigation device 100. The above adjustment action is regarded as the aforementioned adjustment command. The shape of the enclosed area 205 may be circular as in the prior art, or may be in the shape of an amorphous, polygonal, fan-shaped, elliptical or the like that is input by the user. Polygons, such as diamonds, triangles, polygons, stars, etc., are not limited by equilateral or equiangular, as long as they are closed segments (ie, there are no openings, and adjacent edges are connected). The navigation device integrates the shape and configuration of the enclosed area into the aforementioned range data, and combines the range data and the map to calculate a search range on the map (step S130). The shape of the search range is the previous user input. The specific shape of the enclosed region 205, that is, one of various shapes such as a circle, an indefinite shape, a polygon, a sector, an ellipse, a diamond, a triangle, a polygon, a star, and the like. However, when the location data input by the user is of a different type, the navigation device 100 displays different maps, and the setting manner of the closed region 205 is also different. The description is as follows: First, when the location data is the location 202 of the navigation device 100, the location of the closed region 205 on the map is in a corresponding relationship with the location 202 of the navigation device 100. For example, in Fig. 9, on the facet, the closed area 205 is planned at a certain portion of the right front side of the position 202 where the navigation device 100 is located. The navigation device 100 calculates the absolute distance of the center of the enclosed area 205 from the position 202 of the navigation device 100 and the angle ' corresponding to 201017128 to correctly calculate the corresponding position of the subsequently generated search range and the position 202 of the navigation device 100. Moreover, when the navigation device 100 is displaced on the map, the navigation device 仅0 only searches for the interest point data 203 of the right front side of the navigation device_the traveling direction. First, when the location data input by the user is the navigation device, the navigation device 100 can configure the closed area 205 input by the user at the location 202 and a specified address, that is, the address of the designated location 2〇1. At the location 202 where the navigation device 100 is located, it is oriented toward the designated location 2〇1. Alternatively, the user can plan the location M2 of the navigation device and the designated location 201 on the map, with a specific range of closed areas 2〇5 between the two. When the navigation device 100 is navigating, the search range is calculated based on the closed area 2〇5 of the specific range, and the search for the point of interest data 2〇3 is performed in the search range. In the above, when the location data is the foregoing, the user inputs the fingerprint address, the coordinate data or the region name (i.e., the designated designated location 201) of the designated location 2〇1❹, and the map specifies the map to which the location 201 belongs. After the closed area 205 is planned, the navigation device 1 only calculates the search range based on the closed area 205 and searches for the point of interest data 203 in the search range. Finally, the navigation device 1 compares the search range with the map database 152 to match at least one point of interest data 2〇3 (step S140) in the search range and through the display module 14 or the touch screen. Ι7〇 is displayed on such point of interest data (step S150). In the above description, each interest 201017128 point data 203 contains a geographic material and one of its corresponding introduction materials. The foregoing geographic data includes a name of a point of interest, a latitude and longitude coordinate of the point of interest, a distance between the point of interest and a current position of the navigation device, and the introduction data includes at least one text information introducing the point of interest and/or at least one interest. Point the picture. This introduction and geographic information can be combined with the display module and the displayed map. Alternatively, the navigation device 1 first displays the geographic data. When the user clicks on the point of interest, the introduction information of the point of interest is displayed. As shown in Fig. 10, Fig. 11, and Fig. 12A and Fig. 12B, the navigation device sets different search ranges according to the user inputting different types of position data and partial map range data. As shown in FIG. 10, the location data is the designated address, coordinate or area name of the designated location 201. The navigation device 1 displays the closed area 205 previously input by the user on the map to which the designated location 201 belongs. Therefore, the navigation device 100 only The search range 120b is calculated based on the closed area 205 to search the POI data 203 on the map to which the designated location 201 belongs, and the search result is displayed via the display module 130 or the touch screen 170. As shown in Fig. 11, the location data is the designated address (i.e., the query designated location 201) entered by the user and the location 202 of the navigation device 1. Therefore, the navigation device 100 displays the closed area 205 previously input by the user on the map including the designated address of the cover and the location 202 of the navigation device 100, and then performs the point of interest according to the search range 120c of the closed area 205. Search of data 203. As shown in FIG. 11, the closed area previously input by the user is a triangle. When the navigation device 100 navigates, only the point of interest data 203' in the search range 12〇c is searched based on the search range 120c' of the last generated 11 201017128 triangle. The search result is displayed through the display module 13 or the touch screen 17A. As shown in Figures 12A and 12B, the positional data is at position 202 of the sharpening device 10Q. The navigation device 100 establishes a correspondence relationship between the search range 120d and the position 202 of the navigation device 1 according to the closed region 205, so that the search range i2〇d follows the location 202 of the navigation device 100. Perform the same pattern displacement on the map. In the case of 位移 displacement, the navigation device continuously determines whether there is a matching point of interest data in the search range i20d and continuously updates the search result for the display module 140 or the touch screen 170 to refresh the current appearance. Moreover, in such a setting, it is applicable regardless of whether or not the position 202 of the navigation device 100 is included in the search range. As shown in FIG. 12A and FIG. 12B, the search area 12 〇d originally included the point of interest data 203 includes (1) gas station: 5 metric meters, 〇 bank: 25 〇 metric feet, and (3) gas station: 750 meters. At this time, the navigation device 1 will display the geographic information of the park and restaurant of the two gas stations, and when the user clicks on any of the points of interest, the introduction information of the selected points of interest will be further displayed. After that, the navigation device 100 performs displacement, and searches for the 120d synchronous displacement to cover the restaurant and the parking lot. At this time, the navigation point is updated to display the information of the point of interest 203. The output bank: 5G meters and the parking lot: Relevant information. Although the present invention has been described above in the above-mentioned reading (four), it is not intended to limit the present invention, and any equivalents of the modifiers and retouchings are still within the spirit and scope of the present invention.
