Definitions

  • the invention relates to a method for operating a device for determining a route course, in particular a navigation device or a mobile phone with data connection, according to the teaching of claim 1.
  • search queries can relate, for example, to objects which lie along the currently traced route and usually also within a certain radius with respect to the current position of a means of transportation.
  • search queries can relate, for example, to objects which lie along the currently traced route and usually also within a certain radius with respect to the current position of a means of transportation.
  • the user of the navigation system or mobile phone is usually offered the option of restricting the search on the basis of specific search criteria, for example by specifying special destination categories, such as restaurants, petrol stations or museums.
  • the problem with this approach is that the user must be active in the context of the search itself and thereby possibly distracted from the traffic.
  • the user may miss out on interesting points of interest because he is unaware that that such a potential POI, such as a particularly preferred restaurant, is on its upcoming route.
  • US Pat. No. 7,155,339 B2 the user of the navigation system is displayed a list of possible special destinations within defined distance ranges relative to the current position of the means of transportation.
  • the POIs are displayed by the navigation system according to their distance from the means of transport along the currently traveled route.
  • search circular areas are defined, the centers are located on the traveled by the means of transportation and the radius is variable, so that by means of the circular areas various regions are defined, within which is searched for possible points of interest along the route.
  • the circle radii must be specified manually by the user of the navigation device. Also, the user must make an extensive configuration of the system before starting the journey or while driving.
  • Disadvantages of this approach are the manually required interaction between the user and the device as well as the fact that not all the points of interest for the user may be displayed within the specified search environment because the user has either not configured a POI category that may be of interest to him or because he is unaware that a potentially interesting POI could be on the track.
  • the user activates as many as possible POIs, he is most likely supplied with too much information so that he can lose track or even get information that is not of interest to him.
  • US 2003/0167120 A1 teaches the structure of a navigation system which, by means of a data service, obtains map data which are provided with special destinations and which these special destinations are dependent on the current position of the means of locomotion by means of a display device together with the calculated route displays. Also, the system includes a POI memory in which the user can store particularly preferred points of interest.
  • the object of the present invention is to propose a new method for operating a generic device for determining a route in which the user at any time without complex interactions with the device has the opportunity, a special preferred by him special destination in the determination of the route also at short notice in the current route calculation to include.
  • an indication of a possible point of interest is provided by the device continuously and automatically, provided that this is located in the immediate vicinity of the facility location.
  • the method according to the invention causes a permanent position determination taking into account received position signals.
  • a user must have identified himself through appropriate inputs using the user interface of the device.
  • the device performs this user identification automatically by polling the user interface and capturing the user input.
  • the device automatically starts a POI search process to determine position-dependent and user-specific POIs, taking into account the determined current position and the identified user.
  • a search device included in the device searches the memory for POIs or POI categories specified by the user.
  • Device without further user input is able to identify the user-specific points of interest and to consider in the search process.
  • the communication of the result of the POI search operation to the current user is done by means of the user interface, for example using a display device, such as a display.
  • a display device such as a display.
  • the display of the POIs is supplemented by means of specific additional information, such as advertising messages.
  • the device carries out the POI search for the user with each new position fully automatically on the basis of the information obtained by the user identification information. Apart from a user identification before departure then no further interactions between device and user are required. The user can concentrate fully on the traffic during this time and does not have to perform elaborate search criteria configurations. If a corresponding POI is found by the facility, the facility automatically alerts the user to the search result.
  • the user is potentially informed of interesting targets for him, about whose existence the user may not have been informed and which he would pass unnoticed without appropriate notice of the device.
  • the user can choose whether and, if appropriate, to what extent the result of the special destination search process is to be taken into account by the facility when determining the further route. If the user accepts a corresponding notice of the device, it is automatically routed to the point of interest.
  • the point of interest is automatically added to the route and used by the facility as an intermediate destination in the determination of the further route from the current position of the means of transport. taken into account. The route leads inevitably past the point of interest.
  • the device preferably controls the start of the point-of-interest search process automatically, taking into account the particular position of the means of progress in which a POI search process was last started. Only when significant for the determination of POIs significant changes in position of the means of transport is thus a query. It is thus avoided that the data processing device is excessively stressed by unnecessary starts of the search algorithm.
  • a point of interest already determined within the scope of the point of interest search operation is stored by the device automatically and / or by means of a query on the user interface.
  • a POI determined by the device could be stored in an address book included in the device.
  • This automatism ultimately leads to the advantage that the navigation system, the profile of the current user permanently, dynamically and automatically extends, creating a certain learning effect and thereby the specific needs of the user can be covered even better in the future.
  • the device can reconsider points of interest that have already been identified and stored in the context of a previous POI search during new POIs, even during the current trip. Likewise, additional search parameters could be considered.
  • the user is preferably made aware of the special destinations found within the scope of the special destination search process in accordance with a user-parameterable special destination ranking, which are displayed visually on a display device comprised by the user interface, so that the user can quickly obtain an overview of the viewfinder. receives information and is first informed of it for highly relevant goals. It is also advantageous if sorting takes place according to a user-specific evaluation of the points of interest and / or according to further possible user-specific criteria during the result display.
  • the device comprises a first control means which can be freely parameterized, in particular by means of the user interface, by means of which the device automatically controls the start frequency of the point-of-interest search operation.
  • the control means adjusts the start of the search process to the local conditions and thus actively influences the start frequency of the search process.
  • a circular area for controlling the starting frequency is particularly suitable.
  • a first circle center is defined, and by means of the first control means a first circle radius is defined, wherein the starting frequency of the POI search is then controlled taking into account the defined by means of the circle center and the circle radius first circle by checking whether the current position of the means of transportation is still within the first circle defined in the previous search process. If the position is substantially at the circumference of the circle, this is taken as an opportunity to start a new search. In this way, a region surrounding the route can be automatically and rhythmically targeted and, if required, user-specifically searched for points of interest.
