## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the priority benefit of Taiwan application serial No. 98102325, filed on Jan. 21, 2009. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
BACKGROUND
With the continuous advancement and improvement of electronic technology and communication techniques, compact or portable electronic devices such as cellular phones, personal digital assistants (PDAs), PDA phones, car PCs, etc, are also evolving rapidly. The electronic devices in the market now have integrated a greater number of functions to increase their competitiveness. Other than the conventional functions of taking photos, making phone calls, and surfing the internet, the global positioning system (GPS), the electronic map, the navigation system are also integrated in a handheld communication device. Hence, a user can monitor his/her location through the electronic map and the GPS anytime. Also, by the planning and guiding of the navigation system, the route can be determined to reach the destination.
However, the GPS can only function in places with satellite signal reception. Once the user carries the GPS into a building or other places with satellite signal blockage, the positioning will not be proceeded correctly. Under such conditions, when the user needs to position his/her location, he/she can only position his/her location at a place with satellite signal reception, such as a window side, outdoors, etc. Thus, an alternative way must be provided as an option for the user to position his/her own location anytime and anywhere.

DESCRIPTION OF EXAMPLES
Except for global positioning system (GPS), which may be used to estimate a precise location of a mobile device, signals of various communication systems may also be used to estimate an approximate location of the mobile device. The communication system comprises, for example, a global system for mobile communication (GSM) system, a personal handy-phone system (PHS), a code division multiple access (CDMA) system, a wireless fidelity (Wi-Fi) system, a radio repeater, or a radio broadcaster, etc. The present application first obtains the approximate location of the mobile device by the positioning of the communication system, and displays a map around the location on the mobile device. Subsequently, a user selects the desired precise location, for example, the precise location of his/her whereabouts, directly on the map. Accordingly, the present application allows the user to obtain the location information as needed when he/she is in a building or other places with blockage, and share the location information with other uses at a remote end.
FIG. 1 is a flowchart showing a method of selecting a location according to an example of the present application. Referring to FIG. 1, the present example is suitable for mobile devices such as cell phones, smart phones, PDAs, PDA phones, media players, game devices, notebooks, navigation devices, or car PCs, etc, to obtain location information of the mobile device, such as a latitude-longitude coordinate, or an address. The steps of the method are illustrated in the following.
First, the mobile device performs the positioning by using a communication module to obtain a first location (Step S102). The first location is an approximate location of the mobile device. In detail, the communication module estimates a current position of the mobile device by, for example, detecting the signal strength of base stations of communication vendors and referring to geographical locations of the base stations. As the signals of the base stations are possibly influenced by blockage of buildings or transmission distances, the location estimated by the communication module may not be precise. However, at least the approximate location of the mobile device on a map can be obtained. Here, the communication module comprises a GSM system, a PHS, a CDMA system, a Wi-Fi system, a radio repeater, or a radio broadcaster, etc.
After the first location of the approximate position of the mobile device is obtained, an electronic map of a range around the first location is displayed on a screen of the mobile device (Step S104). The range is determined by, for example, a scale of the electronic map. Usually, an electronic map with a radius of less than about 3 km is utilized to clearly label all the street names and landmarks around the first location and allows a user to browse and select his/her location.
Next, the mobile device receives a second location selected on the electronic map by the user. The second location is a precise location and set as location information, for example, the location information of the mobile device (Step S106). In detail, since only the user knows where he/she is located on the map, when the GPS positioning can not function, the most accurate way is to show an interface for the user select to his/her location. By the method of selecting the location in the present application, the electronic map around the current location of the user may be presented to the user in the fastest rate and the best proportion scale. The user only needs to pick a location or select a landmark, an intersection, or even a house number on the electronic map, and the mobile device may automatically set the selected point as the location information of the mobile device so as to achieve the precise positioning function of the GPS.
In one example, the method of selecting the location may incorporate with the GPS to select location information of the mobile device. For example, before the positioning is performed by using the communication module, the GPS may firstly be used to detect satellite signals. If the satellite signals are strong enough for positioning, a latitude-longitude coordinate obtained from the GPS positioning may be used directly as the location information of the mobile device.
In another example, the method of selecting the location may also incorporate with a location list to obtain the location information of the mobile device. The user may set up and collect his/her favorite or often-visited locations such as restaurants and scenic spots as points of interest (POIs) to establish a location list in a manner similar to a contact list. Here, besides names and locations of the POIs, other information such as photos, addresses, and telephone numbers of the POIs may also be recorded. When the user is located at one of the locations in the location list, he/she only needs to select the location from the location list, and the mobile device will automatically set the location of the selected location as, for example, the location information of the current position, the location information of the place to meet up, or the location information to be sent to another user.
By the method of selecting the location of the application, the mobile device may automatically select the location by using suitable method according to the settings, or select the location according to an instruction of the user. After the location information is obtained, the mobile device may further add the location information to a document and send the document to a remote device. Hence, a remote user may receive, for example, the current location of the user or the place to meet up. The following illustrates another example of the present application.
FIG. 2 is a flowchart showing a method of selecting a location according to an example of the present application. Referring to FIG. 2, the present example is suitable for mobile devices, such as cell phones, smart phones, PDAs, PDA phones, media players, game devices, notebooks, navigation devices, or car PCs, etc, to obtain location information of the mobile device and send the location information to a remote device. The steps of the method are illustrated in the following.
First, the mobile device receives a first select signal (Step S202), and obtains location information, for example, the location information of a current position of the mobile device, from an electronic map, a detected current location, or a location list according to the first select signal (Step S204). When a user activates a function of selecting the location, the mobile device may display a plurality of options on a screen for the user to select the method of selecting the location, and execute the location selection method according to the option selected by the user.
In detail, if the mobile device receives the select signal of selecting the location by selecting from the electronic map, then a communication module therein is used to perform the positioning for obtaining an approximate location of the current position. Next, according to the approximate location, an electronic map of a range around the current location is displayed on the screen. Finally, the location selected on the electronic map by the user is detected so that a latitude-longitude coordinate or an address of the location is set as location information, for example, the current location information of the mobile device or the location information of the POI.
In another example, if the mobile device receives the select signal of selecting the location from the detected current location, then a positioning module therein, for example a GPS system, is activated to perform the positioning for obtaining a precise location of the current position. Thus, the precise location is directly used as the current location information of the mobile device or the location information of the POI.
Moreover, if the mobile device receives the select signal of selecting the location from the location list, then a location list is displayed on the screen. The location list comprises the location information of a plurality of locations, and the user may select one location of the location list, such that a latitude-longitude coordinate or an address of the location is set as the location information, for example, the location information of the mobile device.
For example, FIG. 3 shows a user interface of a method of selecting a location according to an example of the present application. Referring to FIG. 3, when the user needs to select a location, he/she may activate a function of selecting the location in the user interface of a mobile device. The mobile device displays a location selecting function menu 300 in the user interface so that the user may select needed location information from an electronic map, a detected current location, or a location list.
FIG. 4 shows a user interface of selecting a location by inserting from an electronic map according to an example of the present application. Referring to FIG. 4, when a user selects an option of “Insert from an electronic map” in the menu 300, the mobile device then performs the positioning by using a communication module therein and displays an electronic map 400 within a range around the current location on a screen, for example, a map with a specific scale, a map with a specific radius around the current location, etc. The user selects a location A on the electronic map 400, and then the mobile device displays a dialogue box of “Insert this location.” At this time, the user may select the location of the location A as location information, for example, the location information of the mobile device, by selecting the dialogue box.
FIG. 5 shows a user interface of selecting a location by inserting from a location according to an example of the present application. Referring to FIG. 5, when a user selects an option of “Inserting from a location list” in the menu 300, the mobile device then displays a location list, for example, a coffee shop list 500, to list out coffee shops that are already saved and/or frequently visited by the user. Here, the user may select one of the coffee shops as location information. For example, if the user is in one of the coffee shops, then he/she may select the coffee shop as the location information of the mobile device.
Through the aforesaid three methods of selecting the location, precise location information can be obtained. At this time, the mobile device further receives a second select signal (Step S206), and adds the location information obtained previously to a document according to the second select signal and sends the document to an appointed remote device (Step S208). Specifically, the mobile device can determine a type of the location information to be inserted in and a format of the document to be inserted according to the demand of the user or the type of the remote device. Herein, the type of the location information comprises a latitude-longitude coordinate, an address, or an introduction of a POI, etc. The format of the document comprises an e-mail, a short message service (SMS), a multimedia messaging service (MMS), a file, a keyhole Markup Language (KML), a Keyhole Markup Zip file (KMZ), a hypertext markup language (HTML), and a special format such as a vCard-like format that is similar to a vCard format and a virtual postcard format, etc.
For example, the mobile device may convert the latitude-longitude coordinate into an address by using a reverse geocoding, and then add the address to the document. In detail, the mobile device may send the latitude-longitude coordinate of the current location to a location server on a network and inquire an actual address corresponding to the latitude-longitude coordinate. Thereafter, the address is added to the e-mail or the SMS to be sent to a remote contact.
In one example, in order to enable the contact of the remote device to directly select the document sent by the mobile device so as to see the actual location of the selected location information, for example the current location of the user, on the electronic map, the mobile device of the present example further comprises finding the fields (e.g. the latitude-longitude coordinate) in the uniform resource locator (URL) address of a network electronic map that are corresponding to the location information. Afterward, the selected location information is transformed and filled in these fields, such that the URL address filled in with the location information can be used to connect to a website of the network electronic map when being selected. Accordingly, when the user of the remote device receives the e-mail or the SMS including this URL address or text, a icon, or a image with a link to the URL address, the user only needs to click on the URL address or the text, icon, or image and then the mobile device connects to the URL address on the internet automatically and displays the network electronic map.
Similarly, the mobile device also may use the same method to add the location information to different format documents such as an e-mail, a SMS, a MMS, a file, a KML/KMZ, a HTML, and a special format such as a vCard-like format that is similar to a vCard format and a virtual postcard format, etc. Hence, the remote contact may obtain the location information sent by the user, for example, the location information of the user's current location.
For example, FIG. 6 shows a user interface for selecting location information type according to an example of the present application. Referring to FIG. 5 and FIG. 6 simultaneously, when a user selects a coffee shop in FIG. 5, the mobile device then sets a location of the coffee shop as location information, for example, the location information of the mobile device. Then, the mobile device displays a location information type menu 600, for example on a top layer of the coffee shop list, for the user to choose for sending the location information in a format of a latitude/longitude coordinate, an address, or a URL address.
In addition, for the location selecting method aforementioned, the present application also provides a hardware device, so that the method can be applied in mobile devices such as cell phones, smart phones, PDAs, or PDA phones, media players, game devices, notebooks, navigation devices, or car PCs. Another example is illustrated in the following.
FIG. 7 shows a block diagram of a system of selecting a location according to an example of the present application.
