Abstract

The invention relates to a method for displaying POls on a display unit of a vehicle and / or a mobile device, wherein closely located POls are aggregated into a cluster using a clustering algorithm. According to the invention, it is provided that - Each POl category is assigned a main icon (H1, H2) and a decorative icon (D1, D2) and - depending on a given priority, at least one prioritized POl is displayed on the display unit using the respective main icon (H1, H2) and the other POls of the cluster are displayed using the respective decoration icon (D1, D2).

Description

[0001] The invention relates to a method for displaying places of interest on a display unit of a vehicle and / or a mobile terminal, wherein adjacent POIs are aggregated into a cluster by means of a cluster algorithm.

[0002] DE 10 2013 006 025 A1 discloses a method and a system for resolving and operating POI stacks in a virtual environment displayed on a screen. Upon selection of a first POI stack with a set of POIs contained in the POI stack, the display of the virtual environment is automatically scaled such that POIs contained in the first POI stack are displayed on the screen such that individual POIs, when correctly positioned in the virtual environment, maintain a minimum size and a minimum distance from their respective neighboring POIs. If the minimum distance is not maintained, a subset of the set of POIs in the first POI stack is combined into a second POI stack depending on the respective position of the individual POIs in the virtual environment.

[0003] Furthermore, DE 10 2017 218 205 A1 describes a method for displaying POIs on a navigation system display and a navigation system. In this process, POIs are aggregated into a cluster by a cluster algorithm module of the navigation system.

[0004] The invention is based on the object of specifying a novel method for displaying POls on a display unit.

[0005] The object is achieved according to the invention by a method which has the features specified in claim 1.

[0006] Advantageous embodiments of the invention are the subject of the subclaims.

[0007] A method for displaying places of interest on a display unit of a vehicle and / or a mobile terminal, wherein closely located places of interest are aggregated into a cluster by means of a cluster algorithm, provides according to the invention that each type of place of interest is assigned a main icon and a decoration icon and, depending on a predetermined priority, at least one prioritized place of interest is displayed on the display unit by means of the respective main icon and the other places of interest of the cluster are displayed by means of the respective decoration icon.

[0008] The places of interest are also referred to as points of interest (POI for short), where type refers to places for the satisfaction of daily needs, for example supermarkets or pharmacies, and / or places for travel-specific needs, such as parking garages, parking meters, restaurants, accommodations, petrol stations or ATMs.

[0009] By applying this method, it is possible to display, based on priorities, essentially adjacent points of interest of different categories simultaneously on the display unit. A user searching for a charging station to charge their vehicle, for example, can use this display to identify that there is also a restaurant or a shop nearby that might be of interest to the user, who might want to spend time there, which requires charging at the charging station.

[0010] Embodiments of the invention are explained in more detail below with reference to drawings.

[0011] Showing: Fig. 1 schematically a number of main icons and associated decorative icons and Fig. 2 schematically shows a possible display after prioritization of a place of interest.

[0012] Corresponding parts are provided with the same reference numerals in all figures.

[0013] Fig. 1 shows two main icons H1, H2 and two decoration icons D1, D2 for each POI, with one decoration icon D1 being assigned to a main icon H1 and another decoration icon D2 being assigned to another main icon H2.

[0014] It is generally known that several points of interest (POIs), such as gas stations, charging stations, restaurants, etc., are often located close to one another. This makes it comparatively difficult to simultaneously display these closely spaced points of interest on a digital map, especially in a navigation system, such as a vehicle or a mobile device.

[0015] Typically, only the point of interest with the highest predefined priority, such as a charging station for charging a vehicle, is displayed on a display unit of the vehicle or a user's mobile device. Other points of interest located close to a charging station, such as restaurants, are displaced by the display of the prioritized point of interest, or are not displayed at all, or only a number of displaced points of interest are displayed. After selecting the visible point of interest, a list of all displaced points of interest then appears, for example.

[0016] In order to show a user several places of interest in the digital map displayed by the display unit, it is provided that each category of places of interest is assigned a decoration icon D1, D2 in addition to a main icon H1, H2.

[0017] According to the Fig. In the embodiment shown in Figure 1, the main icon H1 and the decoration icon D1 represent restaurants as a place of interest, and the additional main icon H2 and the additional decoration icon D2 represent charging stations as a place of interest.

[0018] In particular, all nearby points of interest are clustered and thus assigned to a cluster. Points of interest that would otherwise be crowded out in a map representation are clustered together. Clustering is performed primarily using well-known clustering algorithms.

[0019] The points of interest in the cluster are prioritized based on a user-specified criterion, so that the main icon H1, H2 of the highest-priority point of interest is displayed on the digital map. The decorative icons D1, D2 are used, in descending order of priority, to decorate or complement the main icon H1, H2 with the highest priority.

[0020] In one embodiment, the size of displayed decorative icons D1, D2 is scaled depending on the priority of the additional points of interest. Thus, a decorative icon D1, D2 of an additional point of interest with a first priority is displayed larger than a decorative icon D1, D2 of an additional point of interest with a second priority, whereas the decorative icon D1, D2 of the second priority is displayed larger than a decorative icon D1, D2 of an additional point of interest with a third priority.

[0021] Fig. 2 shows such an arrangement of a main icon H1 and a decoration icon D2.

[0022] The charging station has been assigned a high priority as a point of interest by the user, so that the charging station is represented by the main icon H2 on the display unit. A restaurant is located close to the charging station, although the user may have specified a priority for a dining option that is lower than that of the charging station. Therefore, restaurants are also represented as points of interest in the digital map on the display unit, for example, of the vehicle and / or the mobile device, using a decorative icon D1 that decorates the main icon H2. This means that such an arrangement of points of interest is displayed if there is a restaurant near the charging station.

[0023] If the user is looking for a charging station as a place of interest and has prioritized it, the user can see, when applying the procedure, that there is a restaurant in the immediate vicinity of the charging station, which may be of interest to the user, especially for waiting there while the vehicle is charging at the charging station.

[0024] In one embodiment of the method, prioritization is carried out dynamically depending on the current location of the vehicle and a time of day, so that, especially at lunchtime, a display of charging stations with a nearby restaurant is given higher priority as another location of interest.

[0025] In addition, it is intended that the prioritization of other places of interest is done manually by the user, particularly with regard to his current preferences.

[0026] Alternatively or additionally, the prioritization of other places of interest can be automated and / or dynamic based on an evaluation of the user's historical behavior, particularly with regard to location and / or time.
