FIG. 1 is a block diagram showing a system for item control including a first device 100 and a second device 200 according to an exemplary embodiment. The first device 100 senses an approach of the second device 200 and provides items, such as software data including file data, image data, video data, and audio data; a command object; an application screen component, and the like, or physical data including information on a state of a device. The first device 100 may be any kind of device capable of displaying items and transmitting items through communication, including an embedded device of a personal computer, a PDA, a mobile phone, a smart phone, and a hand-held computer. The first device 100 may provide various items and functions on a screen of a display 110 through user interfaces of various applications. For example, the first device 100 classifies items into classes, stores the classified items, and displays the classified items. Each class of a classified item corresponds to an area of the item as the item is displayed. The second device 100 executes a service linked to a selected area of the displayed, classified item matched to approach information of the second device 200 out of the entire area of the classified items.
The first device 100 generally includes the display 110 and an operation controller 120. The display 110 includes a screen under the control of the operation controller 120 and displays various items and functions depending on situations. For example, the display 110 displays the items classified into a plurality of areas on the screen.
The operation controller 120 divides and classifies the items and displays them through the display 110. Further, the operation controller 120 senses or determines whether the is second device 200 approaches and determines approach information of the approaching second device 200. Also, the operation controller 120 executes a service linked to an area of the classified item matched to the approach information of the second device 200 out of the entire area of the classified item displayed on the display 110. For example, at least one class of the classified item displayed on the display 110 is matched to the approach information of the second device 200 and transmitted to the second device 200.
The approach information of the second device 200 is used to select a class corresponding to a specific area out of an entire area of the classified item on the screen of the first device 100. For example, the approach information may be position, distance, approach direction, moving path, angle, entering speed, entering area, and the like. For example, when a class selected by a user is identified on the basis of the approach direction, the second device 200 may move from left to right on the screen of the first device 100 and/or it moves in the reverse direction. In this case, the first device 100 may recognize that a different class is selected for each motion.
The operation controller 120 includes an item manager 121, a proximity device recognizer 122, a selected service executor 123, and an interface 124.
The item manager 121 divides various kinds of items into a plurality of classes, stores the items, and displays the classified items on the display 110. Each item may be classified according to a request of an application.
The proximity device recognizer 122 includes an optical or ultrasonic sensor and determines whether there is an approaching device. If the second device 200 approaches the first device 100, the proximity device recognizer 122 determines the approach information by recognizing position or distance of the second device 200 and/or sensing motion of the second is device 200, and provides the selected service executor 123 with the approach information.
The selected service executor 123 identifies one or more classes positioned on or associated with the selected area matched to the approach information of the second device 200 out of the entire area of the classified item displayed on the display 110, and provides a service linked to the identified class.
For example, the selected service executor 123 searches for the class corresponding to an area that is matched to a current position of the second device 200 out of the entire area of the classified item displayed on the display 110. Then, the selected service executor 123 provides the second device 200 with the searched class through the interface 124. Otherwise, the selected service executor 120 executes an object command corresponding to the searched class and changes a display state of the display 110.
The second device 200 approaches the first device 100 to receive a portion of or information of the classified item. For example, second device 200 may be a PDA, a mobile phone, or a smart phone. The second device 200 selects a class corresponding to an area out of the entire area of the classified item by the approach motion relative to the first device 100 that is displaying the classified item, and receives the class matched to the selected area.
The second device 200 includes a display 210, a linked service controller 220, and an interface 230.
The display 210 includes a screen under the control of the linked service controller 220 and, for example, visually displays the class obtained from the first device 100 depending on situations. The linked service controller 220 displays the class received through the interface 230 on the display 210 and/or provides a linked service (for example, a magnified display and a partial reproduction of the received selected area) using the relevant class.
The type of the linked service using the received class may be determined by a property of the relevant class, a current mode of the second device 200, or an application executed on the second device 200. For example, if some portion of an image is received from the first device 100, the linked service controller 220 of the second device 200 may magnify the received image portion. When some portion of video data is received, the linked service controller 220 may reproduce the portion or register the portion in a video album.
The interface 230 receives the class of the area selected by the approach motion of the second device via communication with the interface 124 in the first device 100, and transfers the received class to the linked service controller 220.
FIG. 2 is a view illustrating an item control motion of devices according to an exemplary embodiment.
For example, the class corresponding to an area is selected out of the entire area of the classified item displayed on the first device 100 by matching an area in which the class is displayed in the first device 100 with approach information, such as a position and a distance, of the second device 200.
Referring to FIG. 2, a first device 100 classifies and displays an item D120, and a second device 200 receives a class D140 from the first device 100 using an approach motion. A display area D110 of the first device 100 displays the classified item D120 divided into areas determined by the first device 100. A path or trace D130 through which the second device 200 moves is used to select classes of the classified items D120 of the first device 100, for example, the selected class D140 is the class selected by the second device 200.
The first device 100 classifies and displays the items to be displayed as a 2° D. interface, a 3D interface, a holographic image (for example, contents, such as file data, image data, and video data; command objects, such as menus; and application screen components), or the like. Anything that can be displayed by the first device 100 may be divided and classified into areas, and such information may be stored. Further, the first device 100 recognizes approach information, such as a distance or a position, as the second device 200 approaches the first device 100. The first device 100 transmits one or more classes desired by the user to the second device 200 by matching areas of the classified item to the approach information of the second device 200.
If the second device 200 moves along the path D130, the first device 100 may identify the class D140 matched to the relevant moving path D130 and transmit the class D140 to the second device 200. Otherwise, the first device 100 may provide services (e.g., object command) matched to the class D140 that is selected by the approach motion of the second device 200, or change a display state of the first device 100. The second device 200 may approach the class D140 of the first device 100 and obtain the relevant class D140 and provide a linked service according to the class D140.
FIG. 3 (a), FIG. 3 (b), FIG. 3 (c), FIG. 4 (a), FIG. 4 (b), and FIG. 4 (c) are views illustrating kinds of items that can be provided by a first device 100 according to an exemplary embodiment. A display environment to which the first device 100 can apply the classification may be 2D and 3D interfaces, as shown in FIG. 3 (a) and FIG. 3 (b), respectively, as well as a holographic image, as shown in FIG. 3 (c). The 2D/3D interface and holographic image may be divided and classified depending on area and distance.
FIG. 3 (a) shows a state in which an item displayed on a screen is divided and classified into areas using a 2D interface. In the case of a 3D interface shown in FIG. 3 (b), while the item is divided into areas like the 2D interface, a surface viewed in 3D may be totally classified. In the holographic image, as divided by dotted arrows in FIG. 3 (c), classification of the relevant items into areas may be performed according to a distance between the displayed item and the second device 200.
Here, the item to which the classification is applied may be software data, including file data, image data, video data, and audio data; a command object; an application screen component, and the like, or physical data including information on a state of a device. For example, the item that is classified by the first device 100 may be any kind of item that can be directly or indirectly displayed through a screen, such as a simple menu, an image, video data, a music playback list, a telephone number list, and a state of a battery.
FIG. 4 (a) shows a classified image, and FIG. 4 (b) shows a telephone number list classified into areas. Further, it is also possible to classify a state of a battery or the like, i.e., physical data of the first device 100, and express the same in an image, as shown in FIG. 4 (c).
FIG. 5 (a) and FIG. 5 (b) are views illustrating item control motion of devices according to an exemplary embodiment. The first device 100 may detect approach information, such as angle, distance, and position, of the second device 200 approaching the first device 100, and may match one class or several classes of data at a same time.
FIG. 5 (a) is a view illustrating a second device 200 selecting one class of data along a moving path or trace E110 and the second device 200 selecting two classes of data along a moving path E120 from a telephone number list displayed on the screen of the first device 100 through a 2D interface. For example, the user may select one desired telephone number by passing the second device 200 through the selected area on a screen of the first device 100 while the second device 200 is disposed horizontally. Further, the user may select two desired telephone numbers by passing the second device 200 through the selected area on the screen of is the first device 100 while the second device 200 is disposed vertically.
FIG. 5 (b) is a view showing the second device 200 selecting one class of data along a moving path E130 and the second device 200 selecting two classes of data along a moving path E140, from a holographic image displayed by the first device 100. In the case of FIG. 5 (b), the first device 100 measures position and distance of the second device 200 and determines a moving path of the second device 200. The first device 100 transmits one or more classes associated with the selected area matched to the approach information to the second device 200.
Here, in the case that the second device 200 approaches the first device 100 with an angle or slope to receive multiple data as shown in the moving path E140, the first device 100 measures the first approaching distance of the second device 200, and measures a distance to the second device 200 at a time interval (for example, every 0.1 second) several times, and determines the class selected by the user of the second device 200 using a finally or a subsequently measured approaching distance.
FIG. 6 is a view illustrating item control motion of devices according to an exemplary embodiment. The first device 100 may divide a progress bar into areas on the screen that reproduces content, such as video data or audio data, and suitably matches some of the files according to an approach position of the second device 200 so as to transmit such matched files to the second device 200.
If content is reproduced by the first device 100, the second device 200 selects a specific area of the progress bar that is being displayed in the first device 100 by the approach motion as shown in FIG. 6. By doing so, the second device 200 selects the specific area of the content being reproduced in the first device 100 so as to receive the selected area of the content, is or plays the relevant content starting from the selected area. For example, in FIG. 6, the progress bar on the screen of the first device 100 is divided into areas of class C110, class C120, class C130, and so on. The second device 200 may select some area of the item by the approaching position, receive only a portion corresponding to the class C120 and the class C130 from the video data that is being reproduced, or reproduce the video data starting from the relevant portion.
FIG. 7 is a view illustrating an item control motion of devices according to an exemplary embodiment. A specific portion of the item being displayed in the first device 100 may be magnified and displayed in the second device 200. In case the item is an image, a linked service controller 220 of the second device 200 may magnify some of the image received from a selected area and display the magnified image on a display 210.
As shown in FIG. 7, the second device 200 may move along a moving path D210. The second device 200 takes and magnifies an image displayed on the screen of the first device 100 along the moving path D210. So that the user takes a desired area out of the image displayed in the first device 100, the user approximately positions the second device 200 in the relevant area. Then, the first device 100 identifies values of the class stored in each area and the position of the second device 200. Then, the first device 100 transmits at least some of image (i.e., the class corresponding to the approach information out of the image) of the position near the second device 200, and the second device 200 receives magnifies, and displays the transmitted portion of the image on the display 210 of the second device 200. The second device 200 may magnify the portion of the transmitted image to fit the display 210 of the second device 200.
FIG. 8 is a view illustrating item control operation of devices according to an is exemplary embodiment. If the second device 200 approaches the first device 100 while a key event is performed, a linked service controller 220 of the second device 200 may link the class received from the first device 100 and the key event that is being performed and provide a linked service. The user may perform other event operations (e.g., key input) while approaching the item that is divided into different classes, so that the second device 200 may execute transmission or other related operations (e.g., dialing). For example, if a telephone number list is displayed in the first device 100, the user of the second device 200 may dial a telephone number C120 by selecting the telephone number C120 by moving the second device along a path E210 as shown in FIG. 8.
Referring to FIG. 8, the telephone number C210 may be a first class of the telephone number list (i.e., item) displayed on the screen of the first device 100.
In order to dial ‘1. JINI’ out of the telephone numbers of the first device 100, the user of may move the second device 200 near the telephone number C210 on the screen of the first device 100. Thus, the user may receive the telephone number C210 and dial the telephone number C210 by performing an input, for example, by pressing a send key.
FIG. 9 is a view illustrating an item control operation of devices according to an exemplary embodiment. If the second device 200 approaches the first device 100 during execution of an application, the operation controller 120 of the first device 100 may provide some content corresponding to approach information of the second device 200 out of the content linked to applications that are being executed. If an application is being executed in the first device 100, the linked service controller 220 of the second device 200 receives content corresponding to the selected area out of the content linked to the application that is being executed in the first device 100.
For example, if the first device 100 is executing a home shopping broadcast and displays various coupons in areas of lower portion of the screen of the first device 100, if the second device 200 approaches the first device 100, the first device 100 may identify the coupon that is nearest to the position of the second device 200 and transmit the identified coupon to the second device 200.
Referring to FIG. 9, the user may move the position of the second device 200 so as to make the second device 200 approach the first device 100 that is executing a video call application, so that image and audio data that are generated in the first device 100 during the video call may be stored in the second device 200.
FIG. 10 is a view illustrating item control operation of devices according to an exemplary embodiment. The linked service controller 220 of the second device 200 may receive information on a remaining amount of battery of the first device 100 using an approaching operation. Referring to FIG. 10, the user may move the second device 200 so that the information on the remaining amount of battery of the first device 100 is transmitted to the second device 200. The second device 200 may receive the information on the remaining amount of the battery of the first device 100 according to a gauge of the first device 100.
FIG. 11 is a view illustrating item control operations of devices according to an exemplary embodiment. The operation controller 120 of the first device 100 may change a display state of the classified items on the display 110 corresponding to the approach information of the second device 200. The screen displayed on the first device 100 may be changed depending on how the second device 200 is positioned on the screen displayed in the first device 100 or in an area displayed by the first device 100.
This method may be applied to a brick piling game or a tennis game, as shown in FIG. 11 (a) and FIG. 11 (b). If the screen of the first device 100 displays a brick piling game as shown in FIG. 11 (a), the user may control motion of bricks displayed on the first device 100 by changing the position of the second device 200. Further, the user may perform an operation of generating a brick by performing a key press event by pushing a function key in the second device 200. At this time, the first device 100 recognizes the class corresponding to the position of the second device 200 and generates a brick E310 in the relevant class area, and performs the piling operation of the brick E310.
When a tennis game is executed on the screen of the first device 100 as shown in FIG. 11 (b), the user may control the motion of a tennis ball E320 by changing the position of the second device 200. Further, the user may perform an operation of hitting the tennis ball by performing a key press event by pressing a function key on the second device 200. The tennis ball E320 is displayed on the class of the selected area matched to the position of the second device 200.
Referring to FIG. 11 (a) and FIG. 11 (b), if the first device 100 senses the position and key event of the second device 200, the first device 100 newly displays the brick E310 or the tennis ball E320 in the class of the area near the position of the second device 200 on the screen of the first device 100, and displays the motion of the relevant object (i.e., brick and tennis ball). Thus, it is possible to embody the games. Here, the first device 100 changes the display state of information displayed on the first device 100 according to the position, distance, and angle with which the second device 200 approaches the first device 100.
FIG. 12 is a view illustrating item control operations of devices according to an exemplary embodiment. The operation controller 120 of the first device 100 may execute the command matched to the class of the selected area corresponding to the approach information of is the second device 200. For example, when the items displayed on the first device 100 are matched to execution commands in each area, the linked service controller 220 of the second device 200 may execute the command matched to the class of the selected area.
Referring to FIG. 12, the first device 100 displays a movie list on a screen thereof. The user may play a preview image of a movie C320 by moving the second device 200 along a moving path D310 on which a preview button C310 and a portion where the movie C320 whose preview image is desired by the user are located. The movie C320 desired by the user and the command menu C310 to control the movie C320 are both selected by the moving the second device 200 along the moving path D310. Although described as selecting two items along the moving path D310, aspects are not limited thereto such that one, two, or more than to items may be selected by moving the second device 200 along a corresponding moving path.
As described above, it is possible to execute the operations, such as data transmission, copying a specific area of the data, and area magnification, by positioning the second device 200 in a specific area of the first device 100 that is displaying the item. Additionally, it is possible to embody operations, such as a change of display of the first device 100, according to the position of the second device 200.
FIG. 13 is a flow chart illustrating a method for item control according to an exemplary embodiment. First, the first device 100 classifies items to be displayed according to the distance thereof and stores the classified items (S110), and displays the classified items (S120). The first device 100 determines whether an approaching device, i.e., the second device 200, enters an area corresponding to or in which the classified items are displayed (S130). At this time, the user of the second device 200 moves the second device 100 near a desired class in order to select the class of the relevant item (S130).
The first device 100 matches approach information corresponding to a distance and a position of the second device 200 that approaches the first device 100 with the classified item (S140). The first device 100 may select a suitable class out of the entire area of the displayed item and transmit the selected class to the second device 200 (S170).
If the second device 200 approaches the first device 100 with an angle (slope) in order to receive multiple data, the first device 100 measures a first approaching distance of the second device 200, and measures the distance to the second device 200 at a time interval (for example, 0.1 second) several times (S140).
The first device 100 may determine the class selected by the user of the second device 200 using the first measured approaching distance and a finally or a subsequently measured approaching distance. That is, after a measurement task for a time has been completed, if the first measured distance is different from the finally or the subsequently measured distance (S150), the first device 100 determines that the second device 200 has requested multiple data, and then the first device 100 transmits multiple classes of data including a class matched with the finally measured distance and a class matched with the initially measured distance to the second device 200 (S160). If the initially measured distance is identical to the finally or the subsequently measured distance (S150), the class corresponding to the relevant measurement distance is selected and transmitted to the second device 200 (S170). After transmitting the item, the second device 200 informs the user that transmission of the item from the first device 100 has been completed.

The second device 200 receives the class of the selected area matched to the approach information out of the entire area of the classified item from the first device 100. The second device 200 may periodically generate a receiving response while receiving the class (not shown), or inform the first device 100 of a class reception completion after the completion of class reception (not shown). Subsequently, the second device 200 displays the received class on the display 210 (not shown), or provides a linked service using it (S270).
The first device 100 may identify the class matched to the approach information of the second device 200 and then provide services, such as changing a display state of a screen by applying the identification of the class matched to the approach information of the second device 200 (not shown), or executing an object command linked to the identified class (S280).
As described above, the item may be software data including file data, image data, video data, and audio data; a command object; an application screen component, and the like. Otherwise, physical data on a state of a device, such as a battery, may be employed as an item and classified on the screen of the first device 100.
The user may perform operations, such as data transmission, copy and magnification, by performing an operation, such as positioning the second device 200 in a specific area of the first device 100 that is displaying the classified item. Otherwise, linked services, such as changing a display state of screen of the first device 100 or executing the object command matched to the relevant class according to the position of the second device 200, and the like, may be provided.
It will be apparent to those skilled in the art that various modifications and variation can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
