Method for wirelessly adding navigation content to a personal navigation device

The present invention relates to a method for adding navigation content to a personal navigation device, and more particularly to a method for wirelessly adding navigation content to a personal navigation device.

The navigation device with built-in Global Positioning System (GPS) is not only well known but widely used in car navigation devices. The general function of the navigation device includes providing a map database for generating navigation commands on the display of the navigation device, and the navigation device is typically attached to the dashboard or embedded in the dashboard.

The term "navigation device" refers to a device that assists a user in navigating to a predetermined destination. The navigation device is useful for receiving internal information about the location information, such as a GPS receiver, or a receiver that can receive location information. The navigation device itself can self-operate the navigation path, or connect to the remote server, the remote server can calculate the navigation path and provide navigation information to the navigation device, or the navigation device cooperates with the remote server to complete the navigation path operation. . The personal GPS navigation device is not permanently fixed on a vehicle but can be disassembled or loaded on any vehicle at any time. Therefore, the personal GPS navigation device is fully equipped, that is, the personal GPS navigation device includes a built-in GPS antenna, navigation Software and map so you can draw and display navigation paths.

When the user of the personal navigation device does not drive the vehicle, the personal navigation device is typically left on the vehicle. Therefore, users rarely actively add point of interest (POI), issue requests for planning multiple stops, or update maps and other information to personal navigation devices. When it is desired to add any of the above information to the personal navigation device, the user must carry the personal navigation device to leave the vehicle and then enter the user's house to connect the personal navigation device to the computer. Once connected, the navigation content is transmitted through the transmission line (for example The USB cable is transferred from the computer to the personal navigation device, and the navigation content can also be downloaded from the personal navigation device to the user's computer. For example, many users nowadays like to download travel paths or travel diaries that they have created using personal navigation devices. In other examples, whether it is transferring information from a computer to a personal navigation device or downloading information from a personal navigation device to a computer, the user needs to physically connect the personal navigation device to the computer.

Please refer to FIG. 1 . FIG. 1 is a flow chart of a prior art method for adding navigation content to a personal navigation device through a computer.

In the embodiment of Fig. 6, the user manually sets the personal navigation device 10 to the pairing mode using the mode switcher 24. In another embodiment of the present invention, the personal navigation device 10 can use the GPS receiver 22 to determine where the personal navigation device 10 is currently located, and when the personal navigation device 10 is authorized or previously authorized to access the network server When the 270 is paired, the mode of the personal navigation device 10 automatically switches to the pairing mode. Such location may include the user's home or office, and previously authorized location information may be stored in location information 36 of memory 30.

Alternatively, pairing will occur when the personal navigation device 10 is within a predetermined radius of the location that has previously been paired, and when the personal navigation device 10 detects that it is moving away from or starting away from the location previously used for pairing . Similarly, personal navigation device 10 begins to pair with network server 270 whenever personal navigation device 10 detects that it can be connected to the Internet, regardless of the current location of personal navigation device 10.

Please refer to Figure 7. FIG. 7 is a flow chart showing a method of adding navigation content from the computing device 250 to the personal navigation device 10 via the web server 270 in accordance with another embodiment of the present invention. The steps of the method flow chart of FIG. 7 are detailed as follows: Step 400: Start: Step 402: The user uploads the navigation content from the computing device 250 to the personal network space 272 of the network server 270; Step 404: Determine the personal navigation device 10 is located at a location where the web server 270 has previously been paired with the personal navigation device 10; if yes, proceed to step 406, otherwise repeat step 404; step 406: the personal navigation device 10 automatically enters the pairing mode and is navigated by the user by the individual Device 10 initiates a direct wireless connection between personal navigation device 10 and network server 270; step 408: personal navigation device 10 begins and network server 270 when personal navigation device 10 is connectable to the Internet Pairing, and downloading navigation content from the web server 270 to the personal navigation device 10; step 410: ending; after the wireless transmission is complete, the personal navigation device 10 may select automatic shutdown to save power.

In summary, the personal navigation device of the present invention does not have to carry a personal navigation device to the computing device in order to pair the personal navigation device and the computing device when receiving the updated navigation content. In other words, the personal navigation device can receive updated navigation content only by placing the personal navigation device at a normal location, such as in a car parked on a parking lot or in a garage. In addition to directly connecting the computing device to the navigation content, the personal navigation device can also download the navigation content from the network server (the network server acts as a relay storage space for uploading the navigation content by the computing device). In addition to this, the present invention does not limit the personal navigation device to only receive navigation content. In fact, the personal navigation device can also transmit the user's travel content (including the travel path or travel diary created by the user using the personal navigation device) to the computing device or the web server.

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.
