Description

METHOD, APPARATUS AND COMPUTER-READABLE RECORDING MEDIUM FOR SEARCH WITH IMAGE INPUT DEVICE}

The present invention relates to a method, an apparatus and a computer readable recording medium for performing a search using an image input device, and more particularly, to a search query or file location identifier used when a user performs a search on a user terminal device. The present invention relates to a method, an apparatus, and a computer readable recording medium that increase the user's convenience by enabling the configuration using an image input device.

In recent years, as the use of the Internet has become more common, users can obtain various information through Internet searches. That is, after accessing an Internet search site through a terminal device such as a personal computer that can access the Internet, users can search for various contents related to news, knowledge, games, communities, and the like.

In order to perform an internet search and obtain information through the search, a user starts a web browser such as Internet Explorer ^TM , Netscape ^TM , Lynx ^TM , and then enters a URL (Uniform Resource Locator) into the address bar of the web browser. After accessing a web site providing a search service, a search query or the like is generally entered into a search box provided by the web site.

However, from a user's point of view, it is inconvenient to start the web browser every time a simple internet search and then go through the above-described process, which can be a waste of time.

In addition, Web sites that provide Internet search functions may expose a lot of indifferent content, advertisements, etc. (in most cases, the user does not want) on the main page, which may make the user uncomfortable.

In view of the problems of the prior art as described above, a tool called a widget has recently been developed.

In general, a widget refers to a small graphical user interface (GUI) for starting an application program on an operating system (OS) in a user terminal device and displaying a processing result of the application program on a screen. For example, a widget is a program that controls a small window for receiving information from the Internet and displaying it on a screen of a user terminal device. A web browser includes many menus provided by a web browser such as a search, a clock, a calendar, a notepad, a map, and a real-time camera. It refers to a program that can be provided to the user without starting it directly. In addition, a library of user-oriented graphic and data processing programs frequently used by a user may also be included in the widget.

Widgets may be classified into search widgets (ie, widget engines), GUI widgets, and web widgets, depending on the environment used. Examples of search widgets include the Dashboard widget for Apple's Mac OS X v10.4, the Side Bar of Microsoft's Windows Vista, KlipFolio, Yahoo! Widgets (aka Konfabulator), iGoogle, Google Desktop, and others. In addition, the GUI widget refers to a widget that is used as a component of the GUI that can interact with a user, and the web widget refers to a widget that is embedded and used in a web page.

The so-called search widget, which is most widely used, refers to a search tool that provides a small search box on the screen of a user terminal device. The search widget generally refers to a program that enables internet search or other search without starting a web browser.

Usually, the search widget is installed on the user's personal computer and can be freely placed wherever he or she wants, such as the desktop or taskbar, so depending on where it's placed, it's called a desk bar or floating bar. Also called.

As mentioned earlier, the search widget is primarily presented to the user in the form of a small search box for entering search queries, but can include search term autocompletion and shortcuts, as in Internet search sites. It is also useful because of its characteristics that occupy only a small display space.

In addition, by using the search widget, the user can directly perform an internet search without starting the web browser, thereby saving the time required for starting the web browser, thereby obtaining a search result quickly.

That is, as described above, the search widget is not only able to perform an internet search in a user terminal device such as a personal computer, but also is very advantageous to use as a search means due to its compactness and accessibility.

On the other hand, it should be noted that the use of the search widget need not be limited to Internet search only.

In general, even when a user searches for a file stored in his or her terminal device, a user may perform a file search by inputting a search query after starting a Microsoft Windows Explorer or the like through a fairly cumbersome process.

However, in the case of using the search widget, not only the Internet search but also the search in the user terminal device can be performed according to the user setting. In addition, the search in the user terminal device as described above may be performed simultaneously with the Internet search for the same search query.

However, when using the above search widget, the user typically configures the search query using a known character / symbol based input device such as a keyboard connected to the user terminal device.

However, if the user is using a keyboard, it may be easier to enter widely used text such as Korean or English alphabets, but other characters (for example, Chinese, Chinese, Arabic, etc.) are not used well. It takes a lot of time to input characters or symbols that are not provided by the keyboard by default.

In particular, in the case of a user using a wireless portable terminal such as PDA (Personal Digital Assistants), various input buttons and display screens are small, so that the above difficulty is more urgently felt.

An object of the present invention is to solve the above-mentioned problem.

In addition, the present invention allows the user to further use the image input unit in the configuration of the search query for the user when performing a search using the search widget, so that the user can perform the search without being restricted by the input means There is a purpose.

In addition, the present invention allows an image input device to be further used in the configuration of the file location identifier when the user requests a file using a file location identifier such as a URL, so that the user can request the file without being restricted by the input means. The purpose is.

It is also an object of the present invention to enable a user to grasp the extended use of the image inputter, thereby making the user more interested in a system using the image inputter.

The image of '金' transmitted to the server 200 is analyzed by the image recognition and analysis unit 232 of the server 200. Next, when the character / symbol extracting unit 234 extracts a character or symbol corresponding to the image of '에' based on the analyzed information, the degree of similarity between the extracted character or symbol and the image of '金' is extracted. Is calculated. In this case, if the similarity does not exceed the reference value and it is determined that there is no character / symbol corresponding to the input image as it is, recommendable characters and symbols are extracted and output to the recommended character / symbol output window 514. In this case, it is preferable that the order in which the recommended letters or recommended letters are output is in the order of similarity.

The user may find and select one of the recommended letters or recommendation symbols displayed on the recommended text / symbol output window 514 according to the user's intention (that is, the letter '金'). Then, the selected letter '金' may be automatically input to the search box 412 of the search widget 410.

As such, when a user requests a search while a letter '金' is input in the search box 412 of the search widget 410, the server 200 receiving the search request is sent to the search unit 240. The Internet search is performed, and the result is transmitted back to the user terminal device 300.
