- 1. Field of the Invention:
- The present invention relates to mobile device technology. More particularly, the present invention relates to a navigation service system and method using a mobile device equipped with a navigation widget.
- 2. Description of the Related Art:
- A mobile device, also known as a portable device, a handheld device and the like, is a pocket-sized computing device typically having a display screen with touch input or a miniature keyboard (often referred to as a keypad). Many different types of mobile devices, such as a mobile communication device, a Personal Digital Assistant (PDA) and a smart phone, are widely used today. Such mobile devices not only provide a voice call, a video call, and a Short Message Service (SMS), but also offer a variety of useful applications (e.g., a schedule manager, games and the like). More particularly, some recently launched portable devices have a navigation function that provides travel or traffic guide path based on location information.
- A conventional navigation service system using a mobile device has an embedded map that has already been stored in the device. Therefore, when a navigation service is activated, the mobile device retrieves map data in connection with current location information from its own storage and displays retrieved map data on a screen.
- The quantity of such map data is large, so the mobile device needs a large storage capacity to store the map data. Also, since map data should be updated frequently to reflect the newest data, a user often suffers great inconvenience in use. In addition, in order to use a navigation service system in foreign countries, a user has to additionally download map data related to those countries.
- Furthermore, a conventional navigation service system uses limited map data provided by a navigation service provider or a mobile device manufacturer. Therefore, a user is restricted in selection of map data and has difficulty in reflecting desired map data to a navigation service system.
- Moreover, a navigation program used in a conventional navigation service system has a slower loading time because of its large size and requires a large amount of resource for running.
- Therefore, a need exists for an improved navigation service technology that requires no embedded map, allows a user to reflect desired map data, and reduces a loading time.
- An aspect of the present invention is to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present invention is to provide a method and apparatus using a mobile device.
- In accordance with an aspect of the present invention, a method is provided. The method includes obtaining, at an electronic apparatus, one or more candidates based at least in part on a first input associated with a plurality of geographical locations, selecting a destination from the one or more candidates based at least in part on a second input, receiving a map image corresponding to a location of the electronic apparatus and the destination, from an external device, and providing, based at least in part on the map image, a navigation service.
- In accordance with another aspect of the present invention, an apparatus is provided. The apparatus includes a display and a processor-implemented controller. The controller is operatively coupled to the display. The processor-implemented controller is configured to obtain one or more candidates based at least in part on a first input associated with a plurality of geographical locations, select a destination from the one or more candidates based at least in part on a second user input, receive a map image corresponding to a location of the apparatus and the destination, from an external device, and present at least one portion of the map image via the display as at least part of a navigation service.
- In accordance with yet another aspect of the present invention, an apparatus is provided. The apparatus includes storage to store data related to a navigation service to be provided via an external device, and a server module. The server module is operatively coupled to the storage. The server module is configured to receive information associated with a plurality of geographical locations, from the external device, identify one or more candidates based at least in part on the information, retrieve, from the data, a map image corresponding to a location of the external device and a destination selected from the one or more candidates, and transmit the map image to the external device such that the external device can present at least one portion of the map image as at least part of the navigation service

- In exemplary embodiments of the present invention, a widget denotes a customized application that allows a user to edit a standby screen with mainly used contents and to directly activate desired services (e.g., a clock, weather, a search, a calendar, a schedule, stock and the like) without accessing related web sites. Depending on types and features of target services, a widget may be formed in a variety of manners, such as a Java Script, an Extensible Markup Language (XML), or an Open Application Programming Interface (API). Since the widget may be activated in a standby screen, the widget has an advantage of a faster loading time over typical applications.
- In the exemplary embodiments of the present invention, a navigation widget denotes a specific widget configured suitably for a navigation service. A navigation widget may be formed by using the Open API related to map data that a web server provides. Also, a navigation widget may include instructions for a wireless communication unit in a mobile device to receive a list of candidate destinations and related map data from a web server. A navigation widget may further include instructions for a Global Positioning System (GPS) module in a mobile device to receive location information of the device from a GPS satellite. A navigation widget may still further include instructions for a display unit in a mobile device to display a location of the device on a map. A navigation widget may be redesigned to reflect a user's desired map to a navigation service system.
- In the exemplary embodiments of the present invention, a navigation widget controller may be included in a control unit of a mobile device and performs control functions for entire operations, e.g., activation of a navigation widget, of a navigation service system. A navigation widget controller controls a wireless communication unit to transmit location information of a mobile device to a web server and to receive map data in response to location information from a web server. A navigation widget controller then controls a display unit to display a device location on a map. Additionally, a navigation widget controller controls a wireless communication unit to transmit a destination search keyword to a web server, to receive a list of candidate destinations in response to a destination search keyword from a web server, to transmit a selected destination in a list to a web server, and to receive map data in response to a selected destination. Also, a navigation widget controller controls a display unit to display a device location on a map.
- In the exemplary embodiments of the present invention, a navigation widget icon denotes a graphical object arranged in a standby screen to allow execution of a navigation service system. That is, by touching a navigation widget icon (if a mobile device has a touch screen) or selecting a navigation widget icon through key input (if a mobile device has a Liquid Crystal Display (LCD)), a user may execute a navigation service system. If a navigation widget is embedded in a mobile device, a navigation widget icon may appear in a standby screen through a user's menu selection. If a navigation widget is downloaded from a web server, a navigation widget icon may appear in a standby screen automatically or through a user's menu selection.
- The GPS, also known as a global navigation satellite system, is often used for navigation purposes. The GPS uses a constellation of satellites that transmit precise microwave signals, which allow GPS receivers to determine their current location. In an exemplary implementation, a GPS module in a mobile device has a GPS receiver communicating with GPS satellites to track the current location of the device.
- The Open API denotes a user-friendly open interface that web service providers open access ways to the public for specific functions or content services. While a traditional API denotes languages or messages used for communication between an Operating System (OS) and applications, the Open API denotes languages or messages used for communication between web servers. As new programs are developed by using API, it is also possible to develop new services by using the Open API. A number of web servers (e.g., GOOGLE, EBAY, YAHOO, NAVER and the like) currently provide a variety of the Open APIs, and also some web servers offer the Open API related to map data. In an exemplary implementation, a mobile device may utilize destination data and map data, stored in a web server, by using the Open API that a web server provides. Additionally, a user may redesign a navigation widget by using suitable Open APIs various web servers provide.
- A web server is a server that provides web pages (i.e., HyperText Markup Language (HTML) files). A web server has a specific domain name and may be equipped with a web server program capable of serving web pages using HyperText Transfer Protocol (HTTP). In an exemplary implementation, a web server provides map data and a list of candidate destinations to a mobile device. Also, a web server provides the Open API for easier access to the web server from a mobile device.
