Description
本發明係有關於一種在個人導航裝置(personal navigation device)顯示多個興趣點(point of interest,POI)的方法,更明確地說,係有關於一種分散顯示多個鄰近的興趣點以形成花狀來圍繞一個選定的位置的方法。The present invention relates to a method for displaying a plurality of points of interest (POI) in a personal navigation device, and more particularly to a method for displaying a plurality of adjacent points of interest in a distributed manner to form a flower. A method of revolving around a selected location.
以全球定位系統(Global Positioning System,GPS)為基礎的導航裝置係為熟知之裝置且廣泛應用於車輛領域以提供駕駛者導航資訊。一般導航裝置具有之功能包含提供地圖資料庫以於導航裝置的顯示器上顯示導航指示。導航裝置通常以吸附方式或其他架設方式,設置於車輛之儀表板上或儀表板中。The Global Positioning System (GPS)-based navigation device is a well-known device and is widely used in the field of vehicles to provide driver navigation information. A general navigation device has functionality for providing a map repository for displaying navigational indications on a display of the navigation device. The navigation device is usually placed on the dashboard or dashboard of the vehicle in an adsorption mode or other manner.
「導航裝置」一詞意指一裝置能夠提供使用者導航資訊以讓使用者能夠抵達一預設地點。導航裝置可包含一內部系統(如GPS接收器)以用來接收地點資料,或僅為可連接之一可接收地點資料之接收器之裝置。導航裝置本身可計算路線,或者與一遠端伺服器溝通,以使該遠端伺服器計算路線並提供導航資訊給導航裝置。或者,導航裝置可為上述兩種方式之混合,亦即導航裝置本身與遠端伺服器皆參與路線計算的處理。個人GPS導航裝置並非得必須整合於車輛中,而是可以設置於車輛中,或於車輛中使用。一般來說(非必要條件),個人GPS導航裝置係為設備齊全的裝置,如包含內部GPS天線、導航軟體,以及地圖,如此以描繪並顯示所需行進之路線。The term "navigation device" means that a device can provide user navigation information to enable a user to reach a predetermined location. The navigation device can include an internal system (such as a GPS receiver) for receiving location data, or simply a device that can connect to a receiver that can receive location data. The navigation device itself can calculate the route or communicate with a remote server to cause the remote server to calculate the route and provide navigation information to the navigation device. Alternatively, the navigation device may be a mixture of the above two modes, that is, both the navigation device itself and the remote server participate in the process of route calculation. The personal GPS navigation device does not have to be integrated into the vehicle, but can be placed in the vehicle or used in the vehicle. In general (non-essential), a personal GPS navigation device is a fully equipped device, such as an internal GPS antenna, navigation software, and a map to depict and display the desired route of travel.
個人導航裝置的特色之一在於能夠條列附近的興趣點。在郊區,各興趣點之間可能會分散的很遠,而可以簡易地顯示於個人導航裝置的顯示器上。然而,當個人導航裝置行經市區或是其它有很多鄰近興趣點的區域時,所要顯示的興趣點可能會因為數眾多而造成過於靠近或重疊的情況。One of the features of the personal navigation device is the ability to list points of interest in the vicinity. In the suburbs, the points of interest may be scattered far apart and can be easily displayed on the display of the personal navigation device. However, when a personal navigation device travels through an urban area or other area with many nearby points of interest, the points of interest to be displayed may be too close or overlapping due to the large number.
請參考第11圖。第11圖係為說明地圖400之示意圖。地圖400在一個小範圍的區域內,包含許多代表興趣點402之圖標。若使用者欲選擇一興趣點,以查找更多相關資訊或接收至該興趣點的導航指示,由於有眾多代表該興趣點之圖標簇擁在一起,因此對使用者來說是相當困難的。舉例來說,地圖400上的區域404包含許多興趣點402聚集在一起,而使得使用者難以分辨在區域404中的興趣點。Please refer to Figure 11. Figure 11 is a schematic diagram illustrating the map 400. Map 400 is in a small area containing a number of icons representing points of interest 402. If the user wants to select a point of interest to find more relevant information or receive a navigation instruction to the point of interest, it is quite difficult for the user because there are many icons representing the point of interest clustered together. For example, region 404 on map 400 contains a plurality of points of interest 402 gathered together, making it difficult for a user to resolve points of interest in region 404.
從上所述,我們可以了解到當多個興趣點在相當接近的情況下,要在個人導航裝置的顯示器上清楚的顯示是很困難的。為了解決上述問題,先前技術使用幾種不同的手段以將關於興趣點的資訊清楚地呈現給個人導航裝置的使用者。From the above, we can understand that it is very difficult to clearly display on the display of the personal navigation device when a plurality of points of interest are relatively close. In order to solve the above problems, the prior art uses several different means to clearly present information about points of interest to a user of a personal navigation device.
在先前技術中,其中一種顯示多個位置接近之興趣點的方法係為將不同類型的興趣點給予不同程度的優先權。舉例來說,辦公大樓的優先權較低,而醫院或觀光景點的優先權較高。在優先權的等級建立完成後,個人導航裝置便可以設定只顯示具有大於或等於一最小優先權之優先權的興趣點。此外,若在設定這樣的顯示條件後,仍有眾多符合條件的興趣點,則個人導航裝置可以只顯示具有最高優先權的興趣點。In the prior art, one of the methods of displaying points of interest close to a plurality of locations is to give different types of points of interest to different degrees of priority. For example, office buildings have lower priority and hospitals or sightseeing spots have higher priority. After the priority level is established, the personal navigation device can set to display only points of interest having a priority greater than or equal to a minimum priority. In addition, if there are still many eligible points of interest after setting such display conditions, the personal navigation device can display only the points of interest having the highest priority.
然而,以上述方式來顯示興趣點的問題係在於若多個興趣點同時存在於同一位置或鄰近位置,顯示複數種類型的興趣點仍會過於擁擠,在這種情況下只能描繪出一種類型的興趣點,亦即代表具有最高優先權的興趣點的圖標能被描繪出來。另一個相關的問題係在於若一興趣點被選定為使用者之旅程的目的地,而該興趣點所屬類型並未被致能或者被給予足夠高的優先權,該興趣點所代表的圖標仍無法顯示於地圖上。However, the problem of displaying a point of interest in the above manner is that if a plurality of points of interest exist at the same position or in a neighboring position at the same time, displaying a plurality of types of points of interest is still too crowded, in which case only one type can be drawn. The point of interest, that is, the icon representing the point of interest with the highest priority, can be depicted. Another related problem is that if a point of interest is selected as the destination of the user's journey, and the type of the point of interest is not enabled or given a high enough priority, the icon represented by the point of interest remains Cannot be displayed on the map.
此外,在一般個人導航裝置上,使用者通常無法將興趣點所屬類型縮小至更符合需求之範圍。舉例來說,假設使用者欲前往咖哩屋用餐,但個人導航裝置僅能提供「餐廳」分類之興趣點,又或著,若使用者欲選擇特定品牌如星巴克等的咖啡店,但個人導航裝置卻僅能提供「咖啡店」分類之興趣點。In addition, on a general personal navigation device, the user usually cannot narrow down the type of the point of interest to a more suitable range. For example, suppose the user wants to go to the curry house to dine, but the personal navigation device can only provide the "restaurant" classification of interest points, or if the user wants to select a specific brand such as Starbucks, etc., but the personal navigation device However, only the points of interest in the "Coffee Shop" category can be provided.
當使用者繼續開車而使得地圖上顯示的區域改變時,其他問題亦會產生。當地圖的觀點改變時,隨著時間變化,興趣點的相對位置與優先權同樣也會變化,造成某些興趣點的圖標被顯示出來,而某些興趣點的圖標卻消失。這種持續性的興趣點圖標顯示與消失,將會造成使用者的困擾。Other problems arise when the user continues to drive and the area displayed on the map changes. When the viewpoint of the map changes, the relative position and priority of the point of interest also change with time, causing the icons of some points of interest to be displayed, and the icons of some points of interest disappear. This persistent point of interest icon display and disappear will cause user confusion.
多數個人導航裝置製造商通常在設計上會使地圖顯示過多的興趣點(亦即超過使用者一般的需求),以突顯其內容之豐富性。然而,大多數時候,使用者並不需要這其中許多興趣點之資訊。舉例來說,在使用者有特定需求(例如用餐或提款)時,才需要如餐廳或自動取款機等興趣點;在一般駕駛時,使用者並不會需要該些興趣點之資訊。Most personal navigation device manufacturers are often designed to display too many points of interest (ie, exceed the user's general needs) to highlight the richness of their content. However, most of the time, users do not need information on many of these points of interest. For example, when a user has a specific need (such as a meal or a withdrawal), a point of interest such as a restaurant or an ATM is required; during normal driving, the user does not need information about the points of interest.
另外,使用者可選擇顯示在地圖上之一特定興趣點,以取得更多該興趣點之相關資訊。然,若使用者欲選擇之興趣點並未顯示於地圖上,使用者就無法選擇該興趣點以取得其相關資訊。使用者也許需要將地圖放大,或四處移動以期能將欲選擇之興趣點顯示於個人導航裝置上。這對使用者來說是很困擾的事,尤其是當使用者知道特定興趣點的存在,卻無法在個人導航裝置的地圖上找到該特定興趣點的時候。In addition, the user can select one of the specific points of interest displayed on the map to obtain more information about the point of interest. However, if the user's point of interest is not displayed on the map, the user cannot select the point of interest to obtain relevant information. The user may need to zoom in on the map or move around in order to display the point of interest to be displayed on the personal navigation device. This is very troublesome for the user, especially when the user knows the existence of a particular point of interest, but cannot find the particular point of interest on the map of the personal navigation device.
由於個人導航裝置多為觸碰式顯示螢幕,因此,當使用者觸碰地圖上包含複數個興趣點之一特定位置時亦會造成問題;在此情況下個人導航裝置並無法判斷使用者是要選擇哪個興趣點,因而無法正確地顯示其位置之詳細資訊,造成使用者的不便。Since the personal navigation device is mostly a touch display screen, it may cause a problem when the user touches a specific location of the plurality of points of interest on the map; in this case, the personal navigation device cannot determine that the user wants to Which point of interest is selected, and thus the detailed information of its location cannot be displayed correctly, causing inconvenience to the user.
本發明提供一種於一個人導航裝置上顯示複數個興趣點之方法。該方法包含於該個人導航裝置之一顯示器顯示一地圖;於該顯示器之一初始位置接收一觸碰輸入;於該初始位置之一搜尋半徑內之一區域搜尋該複數個興趣點;顯示位於該搜尋半徑之該區域內之該複數個興趣點,其中搜尋到之該複數個興趣點係由對應之複數個圖標所表示,該複數個圖標以及其對應之該複數個興趣點於該地圖上之對應地點之間各自係藉由一線條連接之,該線條係以該初始位置為中心向外延伸;分散該初始位置周圍之該複數個圖標,以使該複數個圖標之間彼此分開;以及逐漸增加該搜尋半徑,以使該搜尋半徑內之該區域增加為一加大區域,並顯示位於該加大區域中額外之興趣點。The present invention provides a method of displaying a plurality of points of interest on a person navigation device.

請參考第1圖。第1圖係為說明本發明之個人導航裝置10之示意圖。個人導航裝置10包含一顯示器12、一GPS接收器14、一處理器16、一使用者介面18、一揚聲器20,以及一記憶體30。顯示器12可為觸控式螢幕。GPS接收器14用來接收個人導航裝置10之目前座標。處理器16用來控制個人導航裝置10的運作。記憶體30用來儲存地圖資料庫32,而地圖資料庫32包含地圖資料以及興趣點資料。另外,記憶體30亦儲存路線選擇軟體34以及興趣點資料36。Please refer to Figure 1. 1 is a schematic diagram illustrating a personal navigation device 10 of the present invention. The personal navigation device 10 includes a display 12, a GPS receiver 14, a processor 16, a user interface 18, a speaker 20, and a memory 30. The display 12 can be a touch screen. The GPS receiver 14 is used to receive the current coordinates of the personal navigation device 10. The processor 16 is used to control the operation of the personal navigation device 10. The memory 30 is used to store a map database 32, and the map database 32 contains map data and point of interest data. In addition, the memory 30 also stores the route selection software 34 and the point of interest data 36.
興趣點資料36中儲存複數個興趣點,而每個興趣點具有至少一對應之興趣點種類標籤。舉例來說,常見之興趣點種類標籤為「加油站」、「餐廳」、「旅館」...等等。為了方便辨識不同興趣點的種類,各興趣點種類亦可擁有代表各自種類之圖標,像銀行可用一金錢符號「$」表示之。The point of interest data 36 stores a plurality of points of interest, and each point of interest has at least one corresponding point of interest category label. For example, the common types of points of interest are "gas stations", "restaurants", "hotels", etc. In order to easily identify the types of different points of interest, each type of point of interest may also have an icon representing the respective category, such as a bank with a money symbol "$".
請參考第2圖。第2圖係為說明包含興趣點116與118以及道路112與114之一地圖110之示意圖。興趣點116對應一地標物, 而興趣點118對應於一觀光景點。若使用者想知道更多興趣點116或118的資訊,使用者可於顯示器上觸碰或選擇興趣點116或118其中之一以得到更多相關資訊。若使用者觸碰地圖上不包含任何興趣點的地方,個人導航裝置10會自動搜尋鄰近之興趣點。本發明僅需使用者在顯示器12所顯示的地圖110上作觸碰的動作,以進行操作或選擇;使用者並不需使用滑鼠或其它指示裝置來操作一指標在地圖110上移動。Please refer to Figure 2. 2 is a schematic diagram illustrating a map 110 containing points of interest 116 and 118 and roads 112 and 114. Point of interest 116 corresponds to a landmark, The point of interest 118 corresponds to a sightseeing spot. If the user wants to know more information about the points of interest 116 or 118, the user can touch or select one of the points of interest 116 or 118 on the display to get more relevant information. If the user touches a place on the map that does not contain any points of interest, the personal navigation device 10 automatically searches for nearby points of interest. The present invention only requires the user to make a touch action on the map 110 displayed on the display 12 for operation or selection; the user does not need to use a mouse or other pointing device to operate an indicator to move on the map 110.
請參考第3圖。第3圖係為說明在另一地圖120中搜尋初始位置115周圍半徑R1內之興趣點之示意圖。以初始位置115為例,在使用者還未觸碰地圖120時,部分或全部的興趣點皆為隱藏,而未顯示於地圖120上。將興趣點之顯示預設為隱藏可避免地圖120過於凌亂並提升其瀏覽之清晰度。在地圖120上顯示過多的興趣點可能會造成使用者在駕駛時不必要的分心。當使用者想知道一區域鄰近之興趣點時,使用者僅需觸碰顯示器12上之任何一位置;在本實施例中,使用者在顯示器12上觸碰之位置為初始位置115。Please refer to Figure 3. FIG. 3 is a schematic diagram illustrating the search for a point of interest within the radius R1 around the initial position 115 in another map 120. Taking the initial position 115 as an example, when the user has not touched the map 120, some or all of the points of interest are hidden and not displayed on the map 120. Presetting the display of points of interest to be hidden can prevent the map 120 from being too messy and improving the clarity of its browsing. Displaying too many points of interest on the map 120 may result in unnecessary distraction of the user while driving. When the user wants to know the point of interest adjacent to an area, the user only needs to touch any position on the display 12; in this embodiment, the position touched by the user on the display 12 is the initial position 115.
當使用者觸碰初始位置115時,個人導航裝置會以初始位置115為中心,在其周圍半徑R1內之區域122搜尋興趣點。若在區域122內找到複數個興趣點,每個興趣點會以對應之圖標表現之,各圖標再以一線條連接至其對應於地圖120上之位置點。圖標130對應於位於位置點131之一停車場。圖標130藉由一線條132連接於位置點131。在第3圖中另包含其它類圖標,例如圖標133對應於一餐廳、圖標134對應於一高爾夫球場、圖標136對應於一博物館、圖標138對應於一醫院以及圖標140對應於一遊客諮詢中心。如圖所示,圖標130、133、134、136、138、140各有相對應之位置點以及連結其位置點與圖標之線條,但在第3圖中僅將對應於圖標130之位置點131及線條132標號,以使版面整齊方便瀏覽。When the user touches the initial position 115, the personal navigation device will search for the point of interest in the area 122 within its radius R1 centered around the initial position 115. If a plurality of points of interest are found in the area 122, each point of interest will be represented by a corresponding icon, and each icon is further connected by a line to its corresponding point on the map 120. The icon 130 corresponds to a parking lot located at one of the location points 131. The icon 130 is connected to the location point 131 by a line 132. Other types of icons are additionally included in FIG. 3, for example, icon 133 corresponds to a restaurant, icon 134 corresponds to a golf course, icon 136 corresponds to a museum, icon 138 corresponds to a hospital, and icon 140 corresponds to a visitor consultation center. As shown, the icons 130, 133, 134, 136, 138, 140 each have a corresponding location point and a line connecting the location point to the icon, but in FIG. 3 only the location point 131 corresponding to the icon 130 will be shown. And the line 132 is marked to make the layout neat and convenient to browse.
請參考第4圖。第4圖係為說明當使用者觸碰初始位置115時之地圖200之示意圖。在使用者觸碰地圖200之前,地圖200顯示複數個道路及道路標記。舉例來說,道路204有其對應之道路標記202,以註明道路204的名稱為「凱達格蘭大道」。同樣地,道路208亦有其對應之道路標記206,以註明道路208之名稱為「中山南路」。地圖200上亦有其它標記,例如單行道標記,可幫助使用者分辨哪些道路為單行道。在使用者觸碰顯示器12顯示之地圖200上之初始位置115後,顯示器12顯示相對應之標記117及線條119,其中線條119連接於標記117及初始位置115之間。一游標會顯示於初始位置115之處,以表示使用者觸碰顯示器12時對應地圖220的位置。於本實施例中,該游標為一小圓形,亦可為其他形狀所代替。標記117為在初始位置115周圍中最靠近初始位置115且個人導航裝置10可提供導航指示之一地點之名稱。當使用者觸碰顯示器12中之初始位置115後,個人導航裝置10會根據初始位置115來搜尋位於其鄰近之一範圍內之興趣點。Please refer to Figure 4. Figure 4 is a schematic diagram showing the map 200 when the user touches the initial position 115. Before the user touches the map 200, the map 200 displays a plurality of roads and road markings. For example, road 204 has its corresponding road marking 202 to indicate that the name of road 204 is "Keda Grand Avenue." Similarly, road 208 also has its corresponding road marking 206 to indicate that the name of road 208 is "Zhongshan South Road". There are also other markers on the map 200, such as one-way street markers, which help the user to distinguish which roads are one-way streets. After the user touches the initial position 115 on the map 200 displayed by the display 12, the display 12 displays the corresponding indicia 117 and line 119, wherein the line 119 is coupled between the indicia 117 and the initial position 115. A cursor will be displayed at the initial position 115 to indicate the location of the corresponding map 220 when the user touches the display 12. In this embodiment, the cursor is a small circle, and may be replaced by other shapes. The indicia 117 is the name that is closest to the initial position 115 in the vicinity of the initial position 115 and the personal navigation device 10 can provide a location for the navigation indication. When the user touches the initial position 115 in the display 12, the personal navigation device 10 searches for a point of interest located within a range of its proximity based on the initial position 115.
請參考第5~10圖。第5圖係為說明在地圖250中之初始位置115周圍一搜尋半徑內之區域220尋找興趣點之示意圖。一經發現,符合條件之興趣點會漸顯於地圖250上。第6圖係為說明在地圖252中代表興趣點之圖標300、310、320以及330。隨著時間的變化,圖標300、310、320及330亦隨之漸顯(亦即圖標漸漸變的更加明顯)並調整其位置,以使各圖標之間保持一預設距離。同時,搜尋半徑亦會逐漸增加,直至到達一預設最大搜尋半徑。於特定實施例中,當使用者於顯示器12上觸碰對應於一興趣點之圖標時,該動作會終止搜尋半徑的增加,並阻止更多的圖標顯示於顯示器12上。然後,個人導航裝置10會提供使用者所選定之興趣點之相關資訊。Please refer to pictures 5~10. Figure 5 is a schematic diagram showing the search for points of interest in an area 220 within a search radius around the initial position 115 in the map 250. Once found, eligible points of interest will gradually appear on map 250. Figure 6 is a diagram illustrating icons 300, 310, 320, and 330 representing points of interest in map 252. Over time, icons 300, 310, 320, and 330 are also faded out (i.e., the icons gradually become more pronounced) and their positions are adjusted to maintain a predetermined distance between the icons. At the same time, the search radius will gradually increase until it reaches a preset maximum search radius. In a particular embodiment, when the user touches an icon corresponding to a point of interest on the display 12, the action terminates the increase in the search radius and prevents more icons from being displayed on the display 12. The personal navigation device 10 then provides information about the points of interest selected by the user.
在特定實施例中,使用者亦可選擇忽略預設最大搜尋半徑而將整個地圖250設定為搜尋半徑之區域220。在另一實施例中,預設最大搜尋半徑可根據使用者之位置是否位於市區內而改變。舉例來說,當使用者係位於鄉間或郊區時,個人導航裝置10增加預設最大搜尋半徑,以使搜尋範圍更加廣泛。相對來說,當使用者位於市區時,可利用較小之預設最大搜尋半徑,以縮小搜尋範圍。換言之,使用者可根據不同情況來設定預設最大搜尋半徑。In a particular embodiment, the user may also choose to ignore the preset maximum search radius and set the entire map 250 as the search radius region 220. In another embodiment, the preset maximum search radius may vary depending on whether the location of the user is located in an urban area. For example, when the user is located in a country or suburb, the personal navigation device 10 increases the preset maximum search radius to make the search range more extensive. Relatively speaking, when the user is located in the urban area, the smaller preset maximum search radius can be utilized to narrow the search range. In other words, the user can set the preset maximum search radius according to different situations.
請參考第7圖。第7圖係為說明地圖254中圖標300、310、320及330持續漸顯並開始改變其顯示位置以避免互相重疊之示意圖。相較於第6圖之地圖252,第7圖之地圖254可以看出,圖標310、320及330已開始彼此分離。請參考第8圖。第8圖係為說明地圖256中圖標300、310、320及330已完全顯示並對應地藉由線條302、312、322及332連接至各圖標實際對應之地點304、314、324及334之示意圖。如圖所示,圖標310非常接近線條322。因此,圖標300、310、320及330會改變各自之位置,以使圖標300、310、320及330和線條302、312、322及332之間互不交會、重疊,或相距一預設距離之內。於第8圖所示之實施例中,圖標310、320其中一方或雙方會改變位置,以使圖標310及線條322之間保持一預設距離。圖標可向任何方向移動,但一般來說,圖標會以初始位置115為中心向外徑向移動或/和切向移動或側向移動。Please refer to Figure 7. Figure 7 is a diagram illustrating that the icons 300, 310, 320, and 330 in the map 254 continue to fade out and begin to change their display positions to avoid overlapping each other. As can be seen from the map 252 of Figure 6, the maps 254 of Figure 7 can be seen that the icons 310, 320, and 330 have begun to separate from one another. Please refer to Figure 8. Figure 8 is a schematic diagram showing that the icons 300, 310, 320, and 330 in the map 256 have been fully displayed and correspondingly connected by lines 302, 312, 322, and 332 to the locations 304, 314, 324, and 334 where the icons actually correspond. . As shown, icon 310 is very close to line 322. Therefore, the icons 300, 310, 320, and 330 change their respective positions so that the icons 300, 310, 320, and 330 and the lines 302, 312, 322, and 332 do not intersect, overlap, or are separated by a predetermined distance. Inside. In the embodiment illustrated in FIG. 8, one or both of the icons 310, 320 may change position to maintain a predetermined distance between the icon 310 and the line 322. The icon can be moved in any direction, but in general, the icon will move radially outward or/and tangentially or laterally with the initial position 115 as the center.
請參考第9圖以及第10圖。第9圖係為說明圖標310持續移動位置以和線條322保持距離之示意圖。第10圖係為說明在地圖260中圖標300、310、320及330改變位置以使互相之間保持一預設距離後所在之最終位置。一般來說,當圖標顯示於地圖上後,若圖標與圖標之間的距離,或圖標以及連接各圖標至其對應之地點的線條之間的距離,或連接各圖標至其對應之地點的線條之間的距離小於一臨界值,各圖標便會改變位置。線條之間的相碰或交叉亦必須避免。因此,當連接各圖標至其對應之地點的線條之間有交叉的情況發生時,可藉由移動對應的圖標或著將交叉之線條所對應之圖標之位置互相調換,同時並將互換之圖標與其地圖上對應之地點以線條重新連接之。Please refer to Figure 9 and Figure 10. Figure 9 is a schematic diagram illustrating the continued movement of the icon 310 to maintain a distance from the line 322. Figure 10 is a diagram illustrating the final position in which the icons 300, 310, 320, and 330 are changed in the map 260 to maintain a predetermined distance from each other. In general, when the icon is displayed on the map, the distance between the icon and the icon, or the distance between the icon and the line connecting each icon to its corresponding location, or the line connecting each icon to its corresponding location The distance between them is less than a threshold and the icons change position. Collisions or intersections between lines must also be avoided. Therefore, when there is an intersection between the lines connecting the icons to their corresponding places, the positions of the icons corresponding to the intersecting lines can be exchanged by moving the corresponding icons or the icons of the interchanged icons. Reconnect with the line corresponding to the map.
在使用者觸碰初始位置115後經過一預設時間,圖標將從地圖上消失;圖標可被設定為逐漸消失或直接消失。若使用者在圖標消 失前選擇了一圖標,個人導航裝置會提供對應於該圖標之興趣點之相關資訊。在特定實施例中,若使用者選擇了顯示器中無任何圖標之一區域,所有圖標將會消失以讓使用者清晰地瀏覽該顯示器。After a predetermined time elapses after the user touches the initial position 115, the icon will disappear from the map; the icon can be set to fade out or disappear directly. If the user is in the icon When an icon is selected in advance, the personal navigation device provides relevant information corresponding to the point of interest of the icon. In a particular embodiment, if the user selects an area without any icon in the display, all icons will disappear to allow the user to clearly view the display.
綜上所述,本發明提供了一種即便興趣點之間的距離非常靠近,仍能清楚地顯示複數個興趣點的方法。對應於興趣點之圖標漸顯於顯示器上並自動改變位置,以使圖標之間互相保持一定距離。因此,使用者可輕易地瀏覽所設定之搜尋半徑內之興趣點。In summary, the present invention provides a method for clearly displaying a plurality of points of interest even if the distance between points of interest is very close. The icon corresponding to the point of interest is gradually displayed on the display and automatically changed position so that the icons are kept at a certain distance from each other. Therefore, the user can easily browse the points of interest within the set search radius.
以上所述僅為本發明之較佳實施例,凡依本發明申請專利範圍所做之均等變化與修飾,皆應屬本發明之涵蓋範圍。The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
