Embodiment Construction

[0033] In the following description, for purposes of illustration and not limitation, specific details are set forth in order to ensure a thorough understanding of the techniques presented herein. It will be apparent to those skilled in the art that the technology can be implemented into other embodiments that proceed from these specific details. For example, the embodiments are primarily described in the context of an in-vehicle navigation device; however, this does not preclude the use of the technology in other embodiments, for example, for static route planning or to provide location-based navigation based on a user-selectable location. Services (such as weather forecasts).

[0034] In addition, those skilled in the art will appreciate that the services, functions and steps described herein can be implemented by using software in conjunction with a programmed microprocessor, application specific integrated circuit (ASIC), digital signal processor (DSP) or general purpose ...

Abstract

A technique, equipment and navigation device for determining location data from a database is presented. A method implementation of that technique comprises receiving a first user input defining an extension of a search corridor relative to a map visualized on a display unit. The search corridor extends from a first map area to a second map area spaced apart from the first map area. In response to a second user input defining one or more characters, location data are determined of at least one location associated with the one or more characters and lying within the search corridor. The technique may be used for searching for an intermediate or target location in connection with calculating a route.

Description

technical field [0001] The present invention relates generally to the field of determining location data from a database in response to user input. Location data can be processed for various purposes, such as for route calculation and providing location-based services. Background technique [0002] Many modern electronic devices process location data (eg, the name of the location and the geographic coordinates of the location). For example, a navigation device is configured to calculate a route from a starting location to a target location based on the geographic coordinates of the locations it contains. The geographic coordinates of the starting location are usually derived from the output of positioning sensors. Alternatively, the geographic coordinates of the target location can be determined from user input. [0003] Some navigation devices are configured to prompt the user to enter the characters used to identify the name of the destination location. The navigation ...
