Description

Method and device for selectively displaying points of interest according to purpose of travel

The present invention relates to a personal navigation device, and more particularly to a personal navigation device that displays a Point of Interest (POI) according to a user's itinerary to reduce distorted display information. .

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.

The term "navigation device" means that a device is capable of providing user navigation information to enable a user to arrive at 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.

Among them, one of the functions provided by the personal navigation system is to list nearby points of interest. In more remote areas, the locations of points of interest are often scattered and distant, so they can be clearly displayed in the display of the personal navigation device. However, in urban areas or other crowded areas, the distance between points of interest may be very close. Therefore, it is difficult to display a plurality of points of similar distances at the same time clearly displayed on the display of the personal navigation device, and the user may be inconvenience in browsing. Furthermore, the points of interest listed in the personal navigation device are not necessarily related to the user's itinerary. For example, when traveling for business reasons, the user may not need information related to the points of interest corresponding to the scenic spots listed in the personal navigation device. Therefore, how to help users filter the points of interest that are not related to their purpose is an important topic of personal navigation devices.

The present invention provides a method of selectively displaying a Point Of Interest (POI) according to a purpose of a trip. The method includes storing a plurality of points of interest in a memory of the personal navigation device, the plurality of points of interest having a plurality of corresponding points of interest tags; inputting a destination to the personal navigation device and providing a trip to the destination a navigation instruction of the route; defining the itinerary of the route of the destination; and displaying the plurality of interest points corresponding to the plurality of POI tags included in the itinerary defined by the itinerary of the destination point.

The present invention further provides a personal navigation device for selectively displaying points of interest according to a purpose of the trip. The personal navigation device includes a memory for storing a plurality of points of interest, the plurality of points of interest having a plurality of points of interest tags; a route selection software for receiving a destination and reaching a destination of the destination a navigation indication of the route, the travel route to the destination has one of the types of trips defined; and a processor for controlling the operation of the personal navigation device and displaying the trip type defined by the travel route of the destination The plurality of points of interest corresponding to the plurality of points of interest tags included.
