DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1 through 7, discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged portable terminals.
The following description is made for a technique for displaying information on a Point Of Interest (POI) included within a closed curve drawn according to a user's touch, and transmitting information on a selected POI to a Mobile Station (MS) through a message in a portable terminal supporting a Mixed Reality (MR) technology according to the present invention.
FIG. 1 illustrates a portable terminal according to an embodiment of the present invention.
Referring to FIG. 1, the portable terminal includes a controller 100, a camera unit 110, a communication module 120, a storage unit 130, a display unit 140, and an input unit 150. The controller 100 includes a POI controller 102, and the storage unit 130 includes a POI Database (DB) 132.
The controller 100 controls and processes a general operation of the portable terminal. Particularly, the controller 100 includes the POI controller 102 according to the present invention. Upon execution of an application providing POI information using MR, the controller 100 controls and processes a function for sensing a touch of a closed curve shape, searching information on a POI existing within a closed curve, and displaying the searched information on a screen of the display unit 140. Also, the controller 100 controls and processes a function for including the POI information displayed on the screen in a message and transmitting the message including the POI information to other MS, by means of the POI controller 102.
Upon execution of the application providing the POI information, the POI controller 102 acquires POI information corresponding to an image input through the camera unit 110. At this time, the POI information may be either acquired from the POI DB 132 or may be acquired from an external device or a network. Here, the POI controller 102 may display the existence of the POI information corresponding to the image on the screen by means of an icon. The icon is displayed in a position of an area of the image corresponding to a corresponding POI.
When the screen is touched by a user during the execution of the application that provides the POI information, the POI controller 102 receives a coordinate of the touch from the input unit 150, and determines if the touch is performed in a closed curve shape. When the touch is performed in the closed curve shape, the POI controller 102 determines if there exists a POI corresponding to an area within a closed curve of the displayed image. Here, the POI controller 102 may determine if the icon is displayed in the area within the closed curve of the displayed image, or may determine if the POI corresponding to the area exists within the closed curve of the displayed image through a search of the POI DB 132. If the POI corresponding to the area exists within the closed curve of the displayed image, the POI controller 102 searches information on the POI in the POI DB 132 and displays the searched POI information on the screen of the display unit 140.
Also, in a state in which the POI information is displayed on the screen, when a Short Message Service (SMS) or Multimedia Message Service (MMS) message send menu is selected, the POI controller 102 converts the POI information displayed on the screen into a text and displays an SMS or MMS message creation screen including the text on the display unit 140. When the MMS message send menu is selected, the POI controller 102 acquires a thumbnail image of an image displayed on the screen and includes the thumbnail image in the MMS message creation screen. Also, in a state in which the POI information is displayed on the screen, when an image capture event takes place by a user, the POI controller 102 captures the screen of the portable terminal to acquire an image, and converts the POI information displayed on the screen into a text. If the MMS message send menu is selected, the POI controller 102 displays an MMS message creation screen including the captured image and the converted text. If a user sends a message, the POI controller 102 controls and processes a function for sending a created SMS or MMS message.
The camera unit 110 includes a camera sensor (not shown) and a signal processor (not shown). The camera unit 110 converts an optic signal sensed through the camera sensor during image photographing into an electrical signal, converts an analog image signal photographed from the camera sensor into digital data through the signal processor, processes the image signal into a frame unit, and provides the image signal to the controller 100.
The communication module 120 performs a function for transmitting/receiving and processing a radio signal of data input/output through an antenna (not shown). Particularly, the communication module 120 processes a signal for transmitting/receiving a message including POI information according to the present invention.
The storage unit 130 stores various kinds of programs and data for general operation of the portable terminal, and includes the POI DB 132 according to the present invention. The POI DB 132 stores POI name and detail information on specific topographical features. The POI DB 132 may be also previously stored, and may be updated by a network or an external device.
The display unit 140 displays state information of the portable terminal, numerals, characters, a large amount of moving pictures and still pictures, and such. Particularly, the display unit 140 displays POI information or a POI icon in a predetermined area of a screen and displays a message creation screen including the text-converted POI information or a POI related image, under control of the controller 100.
The input unit 150 includes a plurality of function keys and numeral and character keys, and provides input data corresponding to a key pressed by a user or a user's touch to the controller 100.
FIG. 2 illustrates a process for displaying information on a POI included within a closed curve drawn according to a user's touch in a portable terminal according to an embodiment of the present invention.
Referring to FIG. 2, if an information provision application using MR is executed in block 201, the portable terminal proceeds to block 203 and displays an image input from a camera on a screen, displaying a POI icon on a preview screen displaying the image thereon. That is, the portable terminal acquires POI information corresponding to the image displayed on the screen and, as illustrated in FIG. 3A, displays POI icons for showing that POI information exists in the image. At this time, the icon is displayed in near the image corresponding to a corresponding POI.
In block 205, the portable terminal senses if a user's touch is generated. If the user's touch is generated, the portable terminal proceeds to block 207 and determines if the touch is a touch of a closed curve shape. That is, the portable terminal recognizes a coordinate of the user's initial contact and, as illustrated in FIG. 3B, determines if the touch forms the closed curve shape. The portable terminal may indicate to a user the position in which the screen is touched by displaying, using dots or lines, coordinates in which the screen is touched.
If the user's touch forms a closed curve shape, in block 209, the portable terminal determines if a POI exists within the closed curve of the displayed image. Here, the portable terminal may determine if an icon is displayed in the area within the closed curve of the displayed image, or may determine if the POI corresponding to the area exists within the closed curve of the displayed image through a search of a POI DB.
If the POI corresponding to the area exists within the closed curve of the displayed image, in block 211, the portable terminal searches information on the POI in the POI DB, and displays the searched POI information on the screen. For example, when a touch is performed in a closed curve shape and one POI exists within a closed curve as illustrated in FIG. 3B, the portable terminal displays information on the one POI on the screen as illustrated in FIG. 3C. Also, when a touch is performed in a closed curve shape and a plurality of POIs exist within a closed curve as illustrated in FIG. 4A, the portable terminal displays information on the plurality of POIs on the screen as illustrated in FIG. 4B.
In contrast, when no POI corresponding to the area exists within the closed curve of the displayed image, in block 213, the portable terminal eliminates the closed curve displayed on the screen and terminates the procedure according to the embodiment of the present invention.
FIG. 5 illustrates a process for transmitting information on a selected POI to other MS in a portable terminal according to an embodiment of the present invention.
Referring to FIG. 5, if a specific POI is selected by a user in a screen displaying an image with the POI in block 501, the portable terminal proceeds to block 503 and displays information related to the selected POI on the screen.
In block 505, the portable terminal determines if a message send menu is selected or an image capture menu is selected.
If the message send menu is selected, the portable terminal proceeds to block 507 and searches information on the selected POI in a POI DB 132, and converts the searched POI information into a text. In block 509, the portable terminal determines whether the message send menu is for transmitting an SMS or MMS.
If the message send menu is for transmitting SMS, in block 511, the portable terminal displays a message creation screen that includes a converted text and proceeds to block 513. For example, in a state in which POI information on a specific building is displayed as illustrated in FIG. 6A, if an SMS message creation menu is selected, the portable terminal displays a message creation screen that includes the POI information on the specific building as illustrated in FIG. 6B.
Alternatively, if the message send menu is for transmitting MMS, in block 515, the portable terminal acquires a thumbnail image of the image displayed on the screen. The portable terminal then proceeds to block 517 and displays a message creation screen that includes the converted text and the thumbnail image, and proceeds to block 513. For example, in a state in which the POI information on the specific building is displayed as illustrated in FIG. 6A, if an MMS message creation menu is selected, the portable terminal displays a message creation screen that includes the POI information on the specific building and the thumbnail image for the specific building as illustrated in FIG. 6B.
If the image capture menu is selected in block 505, the portable terminal proceeds to block 519 and captures the screen displaying the POI information to acquire an image. The portable terminal then proceeds to block 521 and searches information on the selected POI in the POI DB 132, and converts the searched POI information into text.
In block 523, the portable terminal determines if an MMS message send menu is selected. If the MMS message send menu is selected in block 523, the portable terminal proceeds to block 525 and displays a message creation screen that includes the converted text and the captured image, and proceeds to block 513. For example, when the POI information on the specific building is displayed as illustrated in FIG. 6A, if an image capture menu is selected, the portable terminal captures the screen of the portable terminal and acquires an image illustrated in FIG. 6C, and displays a message creation screen including the POI information on the specific building and the captured image as illustrated in FIG. 6D.
If the MMS message send menu is not selected in block 523, the portable terminal terminates the procedure according to the embodiment of the present invention.
Next, in block 513, the portable terminal sends a message composed by a user to an MS, and terminates the procedure according to the embodiment of the present invention.
By transmitting POI information to an MS through a message, a receiving MS that is not equipped with an information provision application using MR may still share the POI information. Also, the MS that receives the message including the POI information is able to determine that a POI is included within the message through a controller, and provide a link function such as ‘Auto Calling’, ‘Web Link’, and ‘Navigation’ on the basis of the POI information as illustrated in FIG. 7.
Additionally, when a user's touch is generated in a closed curve shape as discussed, the present invention performs a function such as selecting a POI icon that exists within a closed curve, but may also perform a function of selecting a different icon using the closed curve. For example, as illustrated in FIG. 8, when a plurality of menu icons exist within a closed curve drawn according to a user's touch, the present invention may simultaneously select the plurality of menu icons.
By displaying information on a POI included within a closed curve drawn according to a user's touch, the present invention has the capability to allow a user to intuitively select a focus for POI display and easily acquire POI information in a portable terminal that supports MR technology. By transmitting information on a selected POI to an MS through a message, the present invention is able to share the POI information even with an MS that does not support MR technology. Also, by using a closed curve drawn according to a user's touch, the present invention has an effect of making multi selection possible.
While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
