Description

Method for storing and retrieving recently visited places and related personal navigation devices

The present invention relates to a personal navigation device, and more particularly to a personal navigation device that can record and conveniently find the location of the personal navigation device that was recently visited.

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 conditions), personal GPS navigation devices are fully equipped devices, such as including internal GPS days. Lines, navigation software, and maps are used to depict and display the route you need to travel.

In general, the personal navigation device generates an event log file correspondingly during the process of providing the user navigation command, and stores it in the personal navigation device. The event log records the details of the visited location, such as the latitude and longitude coordinates received by the personal navigation device via the GPS system. In general, since the event log file is mainly for the purpose of recording, the event log file can record a large amount of information on the visited place, but it is not easy for the user to browse. The event log file may contain too much information, and the user must spend a lot of time interpreting, identifying or understanding the information recorded in the event log file to obtain the required location information. Therefore, how to make it easy for users to browse the location records of recent visits with personal navigation devices is one of the issues that need to be solved in designing personal navigation devices today.

The present invention provides a method of storing and retrieving recently visited places using a one-person navigation device. The method includes detecting whether the personal navigation device stays at a stop location, the stop location includes a start point input to one of the personal navigation devices, input to one of the one of the personal navigation devices, or a rest point Recording the coordinates of the stop location, the time of visiting one of the stop locations, and the event scenario category of the stop location, the event scenario area indicating that the stop location is a point, an end point or a rest point; receiving the personal navigation One of the devices inputs a search request by the user; and displays a list of one of the places where the personal navigation device recently visited based on the search request.

The present invention further provides a personal navigation device for storing and retrieving a location that the personal navigation device has recently visited. The personal navigation device includes a processor, a memory, and a user interface. The processor is configured to control the operation of the personal navigation device, and detect whether the personal navigation device stays at a stop location, where the stop location includes a starting point of one of the trips input to the personal navigation device, and input to the personal navigation device One of the ends of a trip, or a break. The memory is used to record the coordinates of the stop location, the time of visiting the stop location, and the event scenario category of the stop location, the event scenario area indicating that the stop location is a point, an end point or a rest point. The user interface is configured to receive a search request input by a user of the personal navigation device, and display a list of the most recently visited location of the personal navigation device according to the search request.

Please refer to Figure 1. 1 is a schematic diagram illustrating a personal navigation device 10 of the present invention. The personal navigation device 10 includes a display 12, a GPS receiver 14, a processor 16, a user interface 18, a speaker 20, a microphone 22, and a memory 30. The display 12 can be a touch screen. The GPS receiver 14 is used to receive the current coordinates of the personal navigation device 10. The processor 16 is used to control the operation of the personal navigation device 10. The memory 30 is used to store a map database 32, and the map database 32 contains map data and point of interest data. In addition, the memory 30 also stores the route selection software 34 and the most recently visited location material 36.

The recent visit location data 36 is used to store the location that the user has recently visited using the personal navigation device 10, as well as information about the circumstances under which the user visited (e.g., departure or arrival). The location information stored in the present invention can be broadly classified into three main categories: a resting point at which the personal navigation device resides, an end point of the journey in which the personal navigation device 10 provides navigation instructions, or a starting point for the journey in which the personal navigation device 10 provides navigation instructions.

The personal navigation device 10 can determine whether the personal navigation device 10 is located at a rest point based on at least the following conditions. First, when the personal navigation device 10 is in an operational state and stays at the same location for more than a predetermined time, the location can be considered as a rest point. For example, when a vehicle stays at a location for more than a predetermined period of time, it is possible that one of the drivers or passengers is left in the vehicle while the other person leaves the vehicle to do business. Second, when the external power source to which the personal navigation device 10 is connected is turned off, the location where the personal navigation device 10 is located can be regarded as a rest point. For example, when the driver turns off the car and stops the car, the power of the personal navigation device 10 provided by the car is also cut off. Third, when the user manually switches the personal navigation device 10 to a sleep mode through the user interface 18, the location where the personal navigation device 10 is located can be regarded as a rest point. When located at a break point, the user usually does not leave immediately, but acts at rest, such as rest, dining, or shopping. Since the user usually has a specific purpose to stay at the rest point (such as performing the above-mentioned rest, meal or shopping, etc.), the user is likely to visit the rest point again for the same purpose.

The recent visit location data 36 includes the location of each break point, start and end point recorded by the personal navigation device 10, and the date and/or time of the visit. The action of the user to save a place as "My Favorites" by using the personal navigation device 10 is also stored in the recent visit location data 36. In addition to location and datetime data, recent visitor location data36 also includes event scenarios, route categories, and local categories for each location. The event scenario category indicates that its corresponding location is classified as a break point, start point, or end point. The route category indicates that the user has reached the corresponding location by driving, walking or other means of transportation. The local category indicates that its corresponding location is a Point of Interest (POI), a "My Favorite" location, a street, a fork, or other type of location.

Please refer to Figure 2. 2 is a schematic diagram showing the most recent visited location data schema 50 of the most recently visited location data 36 stored in the memory 30. The most recent visited location data structure 50 for each location stored in the recent visit location data 36 includes some or all of the following information: latitude and longitude coordinates, such as the above-mentioned local categories, date/time data of the visit to the location, The scope of the route and the scope of the event scenario.

After the user has recently reached a certain number of places visited by the personal navigation device 10, the user can browse or search for the recently stayed location by viewing the information stored in the recently visited location data 36. Please refer to Figure 3. Figure 3 is a schematic diagram showing that the screen 100 displays the recently stopped locations 110 according to the date of the visit. Each of the stops 110 has a corresponding icon 102 to indicate the local category of the location 110 where the stay is made. For example, the illustration may indicate that the corresponding location 110 is a road, a hospital, a restaurant, a "my favorite" location, or a shopping mall. Each of the stopped locations 110 also has a corresponding date 112 to indicate when the user visited the location 110 where the stay was made. In the present embodiment, the screen 100 displays the location 110 where the user visited yesterday and visited today.

The event scenarios and route categories of each of the stops 110 can also be represented by icons. As shown in FIG. 3, the illustration 104 is a graphic of a car to indicate that the corresponding location 110 has been the starting point of a driving route. The icon 105 is a letter "R" to represent a corresponding resting point 110 as a resting point. The icon 106 is a checkered flag to indicate that the corresponding location 110 is the end of a driving route. The illustration 108 is a graphic of a pedestrian to indicate that the corresponding location 110 has been the starting point of a walking route. Since the stopover location 110 can be categorized according to the date of the visit, the user can easily find out the location of the location by simply remembering when he or she visited the location 110. In addition to "Today" and "Yesterday", the location 110 where you have stayed can also be classified according to other date formats, such as "Last 7 Days" or "Last 30 Days".

In addition to the date, the location where the user has recently stayed may be classified according to other conditions such as location, location category, event scenario category or route category. Please refer to Figure 4. Figure 4 is a schematic diagram showing the screen 120 showing the location 110 where it has recently stayed, sorted according to its location. In the present embodiment, the screen 120 shows that the location 110 is located in the Xinyi District of Taipei City and the Zhongzheng District. Since the location 110 where it is stayed can be categorized according to its location, the user can easily find out the location of the location by simply remembering where the location 110 has been. In addition to the location of the location 110 where it has been stayed, the location 110 where it has been stayed may also be classified according to other conditions, such as the latitude and longitude coordinates of the location where the location 110 is located.

When the user browses the record of the stopover location 110, the user can select the location 110 to stay through the user interface 18, and the personal navigation device 10 will provide the user to the stop location according to the route selection software 34. 110 navigation instructions. In this way, the user can visit a stopover location again based on the recently visited location data 36 stored in the memory 30.

In summary, the present invention provides a method for a user to conveniently store, view, and search for a location that a user has recently visited using a personal navigation device. In this way, the user can easily see where they have recently gone. If the user wants to go to the recently visited location again, the personal navigation device can provide navigation instructions to the places.

The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
