Description

Determining a navigation destination by means of a navigation device

Technical Field

The present invention relates to a method for determining a navigation destination by means of a navigation device and a navigation device for performing the method.

Background

Known navigation devices (navigators, navigation systems) can calculate a route from the current position of the navigation device or a user of the navigation device to a navigation destination that is automatically determined or decided by the user. For example, the navigation destination may be input into the navigation device via a user interface.

In addition, the navigation device is capable of performing destination guidance, wherein the user is guided along a route to a navigation destination with visual and/or audible motion instructions. Instead of a human, the destination guide may guide a pet or a robot to a navigation destination by autonomously driving a vehicle.

Map data stored in a map database is used when calculating route and destination guidance. The map data represents, inter alia, geographical objects such as mountains, waters, towns, buildings and traffic routes.

Disclosure of Invention

It is an object of the invention to perform destination guidance to a navigation destination in a particularly user-friendly manner.

The solution of the present invention for achieving the above object is a method for determining a navigation destination by a navigation device according to claim 1, comprising the steps of:

-receiving a text message having a plurality of words;

-determining a first word of the plurality of words having first location information;

-determining a first navigation destination associated with the first location information; and

-performing destination guidance to the first navigation destination.

The term "word" means a segment of a text message delimited by a separator (e.g., a space) that is composed of a plurality of juxtaposed text characters (letters, numbers, special characters).

The determination of the navigation destination by means of the navigation device on the basis of the location information of the words according to the invention enables destination guidance to be carried out or initiated in a particularly user-friendly manner.

The invention is further developed with reference to the dependent claims.

The first term may be determined by considering a special character immediately following the prefix or suffix of the first term. In this way, for example, derived words, keywords and/or search terms in electronic social networks and electronic short message services can be tagged.

"derived words," "keywords," or "narratives" refer to words that are selectable to describe the contents of an object. The derived word typically has location information from which a navigation destination can be derived. For example, the derived word has location information "bodemuiseum (Museum), from which the navigation destination" Bode-Museum, Am kupfergaben, Berlin (Berlin kupfeiragiben dado Museum) "can be derived.

Examples of such electronic social networks include studiVZ, vk.com, XING, and Facebook. Examples of said electronic short message services are especially SMS and Twitter. In Twitter, the derived words starting with the pound (#) number are called "topic tags". The user names beginning with the symbol "@" are likewise understood to be derived words.

Performing the destination guidance to the first navigation destination may be accomplished by user input. To this end, a text message may be displayed on the touch-sensitive screen. The user may enter the first word by touching the screen. Thereby calculating a route from the user's current location to the navigation destination. Destination guidance along the route to the navigation destination can also be initiated.

Upon entry, the user may select a first word from a plurality of words of the text message, each including location information based on which the word is associated with a navigation destination. In this case, the input may be understood as selecting a certain navigation destination from a plurality of navigation destinations.

Alternatively, the words may be selected automatically, i.e. without user action. For example, the word may be selected that may reach its navigation destination via the shortest route, may reach its navigation destination in the shortest time, or may have the shortest distance from the navigation device. In this case, destination guidance may be automatically initiated.

A text message may be displayed on a screen and determining that the first navigation destination results in marking a first word on the screen. The marking preferably consists of a coloured background of the first word or a specific font colour. Alternatively or additionally, the first word may be marked in another way, for example, using a particular font, bold/italic letters or underlining.

As an alternative or in addition to displaying the text message on the screen, it is also possible to output the text message acoustically, for example using a loudspeaker of the navigation device. In this case, the word may be acoustically tagged, for example, using a sound signal immediately preceding the first word.

A plurality of words, in particular all words, each having location information in the text message may be determined. Additionally, for each determined word, an attempt may be made to associate the word with a navigation destination based on the word's location information. In addition, each word associated with a navigation destination may be marked with indicia on the screen to provide the user with the most navigation destinations possible to select.

Alternatively, it is thus possible to determine only those words in the text message which have location information, which are marked with special characters next to the prefix or suffix of the respective word.

It may not be possible to determine a navigation destination for one or more determined words. For example, the reason may be: the location represented by the associated location information may not be reachable using any available vehicles, a transit route to the location may not be available, or the location is not within a defined geographic area. For example, the availability of vehicles, the availability of traffic routes and/or the definition of geographical areas may be preset by the user of the navigation device.

The navigation destinations may be arranged within the same bounded geographic area. The region may be, inter alia, a country, a group of countries, a federal state, a region, or a geographic administration. Alternatively, the area may be rectangular or circular, with a predetermined radius of, for example, 50km (kilometer), 20km, 10km, or 5 km. In particular, the current position of the navigation device or the current position of the user of the navigation device may be arranged in the center of the area.

The screen of the navigation device may be configured to be touch-sensitive. In this case, the input may be made by the user touching the first word on the screen. This type of input is particularly simple and comfortable.

Additionally, the first word may indicate an event, such as a cultural activity. In this case, the first location information may indicate a location where the event occurs. This enables destination guidance to events to be performed using the method according to the invention.

The first word may be extracted from the graphic belonging to the text message, for example by means of text recognition (OCR-optical character recognition). Text recognition may be performed using, among other things, a data cloud service (cloud service). Further, the first term may be extracted, for example, from a web page belonging to the text message (e.g., from a brief thereof). This opens up more data sources for location information.

A data cloud service may be used to access a central database to determine the first term, determine the first navigation destination, and/or perform destination guidance to the first navigation destination. Alternatively, a computing unit of the navigation device can be used for this purpose, which computing unit accesses a database stored in a memory unit of the navigation device.

The solution of the present invention for achieving the above object is a navigation device for determining a navigation destination according to claim 10, comprising the following components:

-a receiving unit configured to receive a text message having a plurality of words;

-a determining unit configured to determine a first word of the plurality of words having first location information;

-a destination determination unit configured to determine a first navigation destination associated with the first location information; and

a destination guidance unit configured to perform destination guidance to a first navigation destination.

In addition to the mentioned components, the navigation device may also comprise other components, such as a processor, a storage unit, an input unit and an output unit. Preferably, the navigation device further comprises a transmitting unit for transmitting data.

The navigation device can be carried around in a vehicle, such as a road vehicle, a rail vehicle, a flying vehicle or a watercraft. For this purpose, the navigation device may be fixedly built into the means of transport or as a separate portable device. Alternatively, the navigation device may be carried outside the transport means with a person. The navigation means may in particular be a mobile phone or another mobile device having navigation functionality.

The above features, characteristics and advantages of the present invention and the manner of attaining them will become more apparent and the invention itself will be better understood by reference to the following description of embodiments of the invention.

If the term "can" is used in this application, it is both technically feasible and technically practical to implement. If the term "about" is used in this application, it indicates that the exact value is also disclosed.

Drawings

Embodiments of the present invention will be described below with reference to the drawings. In the figure:

FIG. 1 illustrates a method according to the present invention;

fig. 2 shows a navigation device according to the invention; and

fig. 3 illustrates a Twitter message on a non-contact screen of a navigation device according to the present invention.

Detailed Description

Fig. 1 shows a method 100 according to the invention. The method 100 starts in a method step S102. Thereafter, in a method step S104, a text message of the electronic data transfer social network, for example a so-called Tweet (Tweet) of the Twitter network (Twitter), is received. Such a tweet will be described in detail below with reference to fig. 3. Tweets typically contain a so-called topic tag (Hashtag), i.e. a search word that starts with the symbol "#" (pound sign).

In a method step S106 following method step S104, the received tweet is automatically evaluated, wherein in particular at least one navigation destination is determined using the hashtag. In this case, various data sources may be used, such as an address database of a navigation system map library, an internet search, and the like.

In a next method step S108, a text message or a tweet is output, for example on a touch-sensitive screen, wherein at least one of the theme labels is marked in a first color, for example green. The first color indicates to a user of the navigation device that destination address data can be determined for the subject label. In other words, a navigation destination is determined for the subject label. Address data cannot be determined for other subject tags or other words each having location information in the text message. Thus, these thematic labels or words may be labeled in a second color, such as magenta or red. Words relating to an event or activity may be marked in a third color, such as yellow.

Thereafter, in a method step S114, the driver or front passenger selects the marker associated with the destination address data (i.e. the navigation destination). If multiple navigation destinations are determined for the tagged words, a list of these navigation destinations may be displayed to allow further selection.

If the marking of the first color is not set in method step S108, the driver can optionally expand the search depth, for example by entering a voice command. The search depth is explained below with reference to fig. 2.

In method step S116, the navigation system performs the calculation and displays a travel route to the navigation destination selected in method step S114.

In a method step S118, the method ends.

Fig. 2 shows a navigation device 200 according to the present invention, e.g. a navigation device with or without separate operating components. The navigation device 200 comprises both software (program commands, program objects) and

hardware units

201, 202. The navigation device 200 may be configured as a navigator, a navigation system or a navigation apparatus, among others.

The receiving unit 204 performs method step S104. Accordingly, the evaluation unit 206 (which may also be referred to as determination unit 206), the marking unit 208, the selection unit 214 and the destination guidance unit 216 perform the method steps S106, S108, S114 and S116, respectively, as described above with reference to fig. 2. In this case, a microprocessor CPU (control processing unit) or a microcontroller executes program instructions. The marking unit 208 and the selecting unit 214 may also be referred to as a destination determining unit 208/214. The destination guidance unit 216 may be configured as a navigation unit.

The microprocessor CPU accesses a digital volatile memory RAM (random access memory) and/or a digital non-volatile memory ROM (read only memory). The navigation device 200 also has an input/output unit I/O via which a wireless data transmission link 224 can be established, for example, with a smartphone 222 or another device with a mobile radio terminal. For example, the tweets may be transmitted from the smartphone 222 to the navigation device via input/output unit I/O. Alternatively, the navigation device 200 may contain its own mobile radio via which tweets are received. The smartphone 222, or alternatively the navigation device 200, can be connected to the internet 226 via a data transmission link 228 that is wireless in at least some segments.

The navigation device 200 comprises other units not shown, such as a GPS (global positioning system) receiver. The power supply of the navigation device 200 is implemented in a known manner.

Fig. 3 shows a text message 300 of a communication Twitter on a touch sensitive screen 301 (touch screen) of a navigator (navigation system, navigation device) according to the invention. The method as shown in fig. 1 is explained in detail with reference to fig. 3, wherein the navigation destination is determined from the hashtag or from the hashtag and the text. The text message 300 includes a plurality of words, including, inter alia, words 302 through 310 at the beginning and words 312 through 318 at the end.
