  • BACKGROUND
  • 1. Technical Field
  • The present invention relates to a system and method for linking and controlling terminals.
  • 2. Description of the Related Art
  • The smart TV has become very popular in recent times, and various methods have been proposed to increase convenience in performing operations on a smart TV, one such method disclosed, for example, in Korean Patent Publication No. 2011-0078656. However, it is inconvenient for a user to control a smart TV using touch methods, and remote controls for controlling smart TV's are not very efficient.
  • SUMMARY
  • Embodiments include a system and method with which to efficiently control a receiving terminal, such as a smart TV, etc., by using a user terminal, such as a smart phone, etc.
  • An embodiment includes a user terminal that includes: a decoding unit configured to decode image data received from a receiving terminal; a touch display unit configured to display the decoded image; and an information transmitting unit configured to transmit selection information for an event-executing entity included in the decoded image to the receiving terminal.
  • Another embodiment includes a receiving terminal that includes: an information transmitting unit configured to transmit an entirety of or a portion of an image to a user terminal; and an information receiving unit configured to receive selection information for an event-executing entity included in the image from the user terminal.
  • A terminal linkage method according to an embodiment includes: sharing an image with a receiving terminal; receiving input in the form of selection information for an event-executing entity included in the image; and transmitting the selection information to the receiving terminal.
  • A terminal linkage method according to another embodiment includes: transmitting an entirety of or a portion of an image to a user terminal; and receiving selection information for an event-executing entity included in the image from the user terminal.
  • A program of instructions that can be executed to link a user terminal and a receiving terminal according to an embodiment can be tangibly embodied in a recorded medium readable by a digital processing device, where the program of instructions are for a method that includes: sharing an image with the receiving terminal; receiving input in a form of selection information for an event-executing entity included in the image; and transmitting the selection information to the receiving terminal.
  • A program of instructions that can be executed to link a user terminal and a receiving terminal according to an embodiment can be tangibly embodied in a recorded medium readable by a digital processing device, where the program of instructions are for a method that includes: transmitting an entirety of or a portion of an image to the user terminal; and receiving selection information for an event-executing entity included in the image from the user terminal.
  • In a method and system for linking and controlling terminals according to an embodiment, the receiving terminal can provide the user terminal with an entire or a portion of a displayed image, the user can select an event-executing entity included in the image via the user terminal, and the user terminal can transmit the selection information of the event-executing entity to the receiving terminal.

  • DETAILED DESCRIPTION
  • Certain embodiments of the present invention will be described below in more detail with reference to the accompanying drawings.
  • A system for linking and controlling terminals according to an embodiment relates to linking and controlling terminals, especially by sharing an image and controlling the operation of a terminal based on the shared image. In particular, a system for linking and controlling terminals according to an embodiment can link a smaller terminal (e.g. smart phone, tablet PC, etc.), which is controlled by a touch method, with a larger terminal (e.g. TV, etc.) and enable various methods for controlling the larger terminal with the smaller terminal. That is, a system for linking and controlling terminals according to an embodiment can control a larger terminal with a smaller terminal utilized as a remote control.
  • For the sake of convenience, the smaller terminal controlled directly by the user will be referred to as the user terminal or a mobile terminal, and the larger terminal that receives the position information of the touch means from the user terminal will be referred to as the receiving terminal or a display device. Although the user terminal may preferably have a smaller size compared to the receiving terminal, the sizes of the terminals are not thus limited.
  • The terminals used in a system according to an embodiment may be provided with a function for display images and a function for wired/wireless communication, but the communication function is not necessarily essential to the invention. Considering real-life applications, however, it may be preferable if each of the terminals is equipped with an image display function and a communication function. The terminal is not limited to a particular type of device, as long as it is capable of displaying images and exchanging signals with the another terminal, and various devices, for example such as a smart phone, smart TV, remote control, PC, tablet PC, laptop, touch pad, game console, cloud PC, etc., can be used as the terminal in an embodiment. However, it may be preferable if the smaller terminal is equipped with a touch function.
  • A system for linking and controlling terminals according to various embodiments of the present invention will be described below in detail with reference to the accompanying drawings. For convenience, the image shared by the terminals will be referred to as a first image, and the image representing the position information of the touch means will be referred to as a second image (position image).
  • FIGS. 1A through 1D schematically illustrate a system for linking and controlling terminals according to an embodiment.
  • Referring to FIG. 1A, a system for linking and controlling terminals according to this embodiment can include a user terminal 100 and a receiving terminal 102, where the terminals 100 and 102 can be computing apparatuses.
  • The user terminal 100 may be a terminal that can be directly controlled by the user and can be, for example, a smart phone, remote control, etc., that is capable sharing an image with another device. Also, the user terminal 100 can be a terminal having a relatively small size and having a touch function, and for example can be a mobile terminal.
  • The receiving terminal 102 may be a terminal that is not directly manipulated by the user but is linked with the user terminal 100, and can be a display-enabled terminal. That is, the receiving terminal 102 may be any device capable of displaying an image, and from the perspective of displaying an image, can also be referred to as a display device. The receiving terminal 102 can be a device used for a different purpose from that of the user terminal 100, and for example can be a TV for showing broadcast programs such as a drama series. In an embodiment, the receiving terminal 102 may be a terminal having a relatively larger size, although it may not necessarily have a touch function.
  • The overall size of the receiving terminal 102 can be larger than the overall size of the user terminal 100, but it may be sufficient if the size of the display unit on the receiving terminal 102 is larger than the size of the display unit on the user terminal 100. In the latter case, the overall sizes of the user terminal 100 and receiving terminal 102 need not be considered.
  • The terminals 100 and 102 can be connected directly in a wired or wireless manner or indirectly using another device as a medium. In one embodiment, the user may use the user terminal 100 to control the operation of the receiving terminal 102, more specifically the operation of a program displayed on the receiving terminal 102. Thus, the user terminal 100 can be located at a distance that allows near-field communication with the receiving terminal 102, and can be located for example at a distance from which the user can view the receiving terminal 102. Of course, the communication between the terminals 100 and 102 is not limited to near-field communication; for example, the user can control the operation of a receiving terminal 102 inside the home by using a user terminal 100 from outside the home. This is possible because the user terminal 100 shares at least a portion of the first image displayed on the receiving terminal 102. Consequently, the control of the receiving terminal can be freed from the limitation of place.
  • According to an embodiment, the receiving terminal 102 can transmit to the user terminal 100 the image data corresponding to at least a portion of the first image 110 displayed on the receiving terminal 102. The user terminal 100 may display a first image 110 corresponding to the transmitted image data. That is, the user terminal 100 and the receiving terminal 102 can share the first image 110, as illustrated in FIG. 1B.
  • Of course, although the first image 110 displayed on the user terminal 100 may be substantially the same as the first image 110 displayed on the receiving terminal 102, the contrast or display proportion, etc., may differ according to the properties of the user terminal 100. The user terminal 100 can display the first image 110 as is, without particularly processing the transmitted image data, or the receiving terminal 102 can convert the resolution, etc., of the transmitted image data and then display the first image 110 corresponding to the converted image data. In another example, a separate device connected with the user terminal 100 can convert the image data transmitted from the receiving terminal 102 to a format suitable for the user terminal 100 and then transmit the converted image data to the user terminal 100.
  • That is, as long as the receiving terminal 102 and the user terminal 100 display substantially the same first image 110, the method of processing the image data at the user terminal 100 can be modified in various ways.
  • According to another embodiment, the user terminal 100 can transmit the image data corresponding to the shared first image 110 to the receiving terminal 102 and thus share the first image 110.
  • When the first image 110 on the receiving terminal 102 is changed, the receiving terminal 102 can transmit image data corresponding to the changed first image 110 to the user terminal 100. Consequently, the user terminal 100 and the receiving terminal 102 can continuously share the first image 110.
  • Also, when a user selects a particular event-executing entity, for example, from among the first image 110 displayed on the user terminal 100, the user terminal 100 can transmit the information on the selection of the event-executing entity (the selection information) to the receiving terminal 102. In this case, the receiving terminal 102 can execute a corresponding operation in accordance with the transmitted information, and as a result, the first image 110 can be changed. Of course, image data corresponding to the changed first image 110 may be transmitted to the user terminal 100. That is, the user can use the user terminal 100 to control the operation of the receiving terminal 102, particularly the operation of a program executed by the receiving terminal 102.
  • The selection information can include position information corresponding to a touch input for selecting an event-executing entity. Alternatively, the selection information can include control information for executing an event-executing entity selected by the touch input. The user terminal 100 can generate the position information or control information in accordance with the touch input.
  • The receiving terminal 102 can execute an operation corresponding to the event-executing entity by using the position information corresponding to the touch input. Alternatively, the receiving terminal 102 can execute the operation corresponding to the event-executing entity by using the control information.
  • The selection of the event-executing entity can be determined according to the pressure or area by which the touch means touches the user terminal 100, and as will be described later on, the event-executing entity can be selected when the user touches the user terminal 100 by a pressure or area exceeding a preset pressure or area. This will be described later in more detail.
  • A description will now be provided on various embodiments by which a user can control the operation of the receiving terminal 102 by using the user terminal 100.
  • According to an embodiment, the user terminal 100 can display a third image (a position image) 114 indicating the position information of a touch means that is in a touch-sensitive region of the user terminal 100, for example a touch means that is near the display unit or is touching the display unit with a pressure or area smaller than or equal to the preset pressure or area, as illustrated in FIG. 1C. That is, the position of a touch means can be shown on the user terminal 100, so that the user may control user terminal 100 conveniently. The touch means is not limited to a particular form and can be a finger, a touch pen, etc. Here, being near may refer to the touch means being positioned with a preset distance from the user terminal 100, including the case of the touch means contacting the user terminal 100.
  • According to another embodiment, if a touch means is brought near to the user terminal 100 or is touching with a pressure or area smaller than or equal to a preset pressure or area, a second image 112 such as a pointer, a shadow image, etc., corresponding to the position information of the touch means can be displayed on the receiving terminal 102 together with the first image 110, as illustrated in FIGS. 1B through 1D. The second image 112 can be substantially the same as the third image 114 or can have a different shape or color.
  • That is, the position of the touch means can be specified on the user terminal 100 and the receiving terminal 102. As the second image 112 is displayed on the receiving terminal 102, the user can control the operation of the receiving terminal 102 while viewing only the receiving terminal 102 and without looking at the user terminal 100.
  • In an embodiment, the second image 112 or the third image 114 corresponding to the position of the touch means can be changed according to the touch pressure or the touch area of the touch means contacting the user terminal 100. For example, if the touch means touches the user terminal 100 with a pressure or an area smaller than or equal to a preset value, then a third image 114 corresponding to the position of the touch means may be shown on the user terminal 100, whereas if the touch means touches the user terminal 100 with a pressure or an area exceeding the preset value, then the third image 114 corresponding to the position of the touch means may not be shown on the user terminal 100 or may be changed to a different shape. This operation can also apply in a similar manner to the second image 112 displayed on the receiving terminal 102.
  • According to another embodiment, the shape of the second image 112 or third image 114 can be varied according to the distance between the touch means and the user terminal 100. For example, the image 112 or 114 can be shaped as a shadow if the distance between the touch means and the user terminal 100 is within a first distance and can be shaped as a finger if the distance between the touch means and the user terminal 100 is within a second distance smaller than the first distance.
  • In various different embodiments, at least one of the position of a touch means near to the user terminal 100, the position of a touch means touching the user terminal 100 with a touch pressure smaller than or equal to a preset value, and the position of a touch means touching the user terminal 100 with a touch area smaller than or equal to a preset value can be indicated by a second image 112 or a third image 114.
  • In short, the user can control the operation of the receiving terminal 102 conveniently by using the user terminal 100. As a second image 112 indicating the position information of the touch means is shown on the receiving terminal 102, the user can use the user terminal 100 to control the receiving terminal 102 while viewing only the receiving terminal 102, without having to look at the user terminal 100. In particular, even when the user does not have a separate control means, the user can control the receiving terminal 102 by using a smart phone, for example, carried by the user.
  • Since the user can control the user terminal 100 by using a touch means, not only can the user select an event-executing entity to execute a particular operation, but also the user can input particular characters, etc., and even work on documents on the user terminal 100. Such operations on the user terminal 100 can be reflected immediately on the receiving terminal 102.
  • Also, since the touch means can be utilized as a mouse for a computer, etc, to perform various operations, the user can control the receiving terminal 102 with greater convenience. For example, the user can scroll, copy, or search, etc., articles in a portal site remotely on the user terminal 100 which may be reflected on the receiving terminal 102. Of course, the second image 112 indicating the position information of the touch means may be shown on the receiving terminal 102, allowing the user to perform a desired operation by looking at the second image 112 displayed on the larger-sized receiving terminal 102. That is, embodiments can involve showing a second image 112 on the receiving terminal 102 to allow the user to control the receiving terminal 102 conveniently, using the user terminal 100 to implement various functions performed by a remote control, a mouse, a touch pen, etc. Thus, a receiving terminal 102 such as a smart TV, which can perform various functions, can be controlled in a convenient manner by using a user terminal 100 typically carried by the user.
  • Although the descriptions above refer to the user terminal 100 as transmitting the image data for the first image 110 and the position information of the touch means separately to the receiving terminal 102, the user terminal 100 can just as well indicate the position of the touch means in the first image 110 and transmit the first image 110, in which the position of the touch means is indicated, to the receiving terminal 102. For example, the user terminal 100 can superimpose the position image for the touch means over the first image 110 and transmit the image data, with the position image of the touch means superimposed, to the receiving terminal 102.
  • In another example, the user terminal 100 can modify a region corresponding to the position of the touch means in the first image 110 to a position image for the touch means. That is, the user terminal 100 can modify the first image 110 itself and create a new image to indicate the position of the touch means, and can then transmit the created image to the receiving terminal 102.
  • According to another embodiment, if the user does not wish to show the second image 112 during linked operation, the user can select a menu item or input a button manipulation, etc., on the user terminal 100 or on the receiving terminal 102 to stop showing the second image 112 or the third image 114. In this case, the user terminal 100 can continuously transmit the position information of the touch means to the receiving terminal 102 and the receiving terminal 102 can store the transmitted position information, so that the receiving terminal 102 may display the second image 112 corresponding to the position information upon the user's request.
  • According to yet another embodiment, the linkage and control system can include a user terminal, a receiving terminal, and a linkage server. The linkage server can transmit image data corresponding to the first image to the user terminal and the receiving terminal, and the user terminal can transmit the position information of the touch means to the receiving terminal, so that the second image indicating the position information of the touch means may be shown together with the first image at the receiving terminal. Here, the linkage server can pre-store the resolution information, etc., of the user terminal and the receiving terminal to process the image data based on the stored resolution information, etc., before transmitting it to the user terminal and the receiving terminal.
  • Terminals such as smart phones, TVs, etc., use wire communication standards such as High-Definition Multimedia Interface HDMI, Mobile High-definition Link MHL, Displayport, etc., and wireless communication standards such as Digital Living Network Alliance DNLA and WiFi, etc., and are each provided not only with data channels for transmitting data but also with a separate channel for exchanging control signals. For example, HDMI uses Consumer Electronic Control CEC, Display Data Channel DDC, Utility, and SCL/SDA as control channels; MHL uses CBUS as a control channel; and Displayport uses the auxiliary channel as a control channel. Thus, it may not be necessary to establish separate channels for linking the terminals 100 and 102, and the channels already available on the terminals 100 and 102 can be utilized for a channel by which to transmit the position information of the touch means according to an embodiment.
  • The terminals 100 and 102 can exchange data in various forms according to the communication method used for the linkage system.
  • A description will now be provided of a method for specifying the touch position of the touch means at the receiving terminal 102.
  • In an embodiment, the position information of the touch means can be the position information on the first image displayed on the user terminal 100. Consequently, the position of the touch means on the first image of the user terminal 100 can be reflected in the first image 110 of the receiving terminal 102 as the second image 112.
  • In another embodiment, the position information of the touch means can be coordinate information that is in accordance with the resolution or screen size of the display unit of the user terminal 100. That is, the position information of the touch means can be the coordinate information of the touch means with respect to the display unit of the user terminal 100, rather than the coordinate information of the touch means on the image displayed on the screen.
  • In still another embodiment, when the user terminal 100 is to show the image data transmitted from the receiving terminal 102 in order that the user terminal 100 and the receiving terminal 102 may share the first image 110, the user terminal 100 can display the first image 110 corresponding to the image data after setting the screen to the same resolution as the receiving terminal 102. Thus, the user terminal 100 can accurately represent the position of the touch means by displaying the second image 112 with the position information, e.g. the coordinate information, of the touch means unmodified.
  • That is, the present invention can employ various methods for specifying the position of the touch means at the receiving terminal 102. The user terminal 100 can transmit the position information of the touch means to the receiving terminal 102, or generate second image data corresponding to the second image representing the position information and send this second image data to the receiving terminal 102, or transmit the first image to the receiving terminal 102 with the region corresponding to the position of the touch means modified.
  • The method for linking and controlling terminals according to various embodiments will be described below in more detail with reference to the accompanying drawings.
  • FIG. 2A and FIG. 2B illustrate a method of linking and controlling terminals according to a first embodiment.
  • Referring to FIG. 2A, the receiving terminal 102 can transmit image data corresponding to a first image 110 that includes an event-executing entity 200, such as a UI, icon, application program, link, etc., for example, to the user terminal 100. Consequently, the first image 110 displayed on the user terminal 100 can include the event-executing entity 200.
  • According to an embodiment, when the user touches the event-executing entity 200 with a touch means, the user terminal 100 can transmit selection information, which notifies that the event-executing entity 200 was selected, to the receiving terminal 102. The selection information can include position information corresponding to a touch input for selecting the event-executing entity 200 or, depending on the touch input, control information for executing the event-executing entity 200.
  • The receiving terminal 102 can recognize that the event-executing entity 200 was selected, based on the information corresponding to the touch input, and can execute an operation related to the selection of the event-executing entity 200. Alternatively, the receiving terminal 102 can execute the related operation by using the control information for executing the event-executing entity 200. Thus, the user can control the operation of the receiving terminal 102 by using the user terminal 100.
  • Here, if the user brings a touch means near the event-executing entity 200 of the user terminal 100 or touches it with a pressure or an area smaller than or equal to a preset value, then a second image 112 can be shown on the receiving terminal 102 in a position corresponding to the position of the touch means. Of course, a third image 114 indicating the position of the touch means can be shown on the user terminal 100 as well. If the user touches the event-executing entity 200 with the touch means with a pressure greater than the preset pressure or an area greater than the preset area, then the receiving terminal 102 can perform an operation corresponding to the event-executing entity 200, for example by activating a game, etc. In this case, the first image 110 displayed on the receiving terminal 102 can be changed.
  • This method of linking terminals can be very useful not only for games, navigation, etc., but also for controlling a smart TV by using a user terminal 100, as illustrated in FIG. 2B.
  • FIG. 3 illustrates a method of linking and controlling terminals according to a second embodiment.
  • Referring to FIG. 3, it is also possible to transmit to the user terminal 100 only the image 300 corresponding to a UI for control from among the first image 110 displayed on the receiving terminal 102, so that the user terminal 100 can display a corresponding image 302. That is, the user terminal 100 and the receiving terminal 102 can share just a portion of the image, especially a portion including an event-executing entity. In this case, a second image 112 indicating the position of the touch means may be displayed on the receiving terminal 102. Of course, a third image 114 indicating the position of the touch means can also be displayed on the user terminal 100, where the third image 114 can be substantially the same as the second image 112.
  • In such a linkage system, when the user touches an event-executing entity in the image 302 displayed on the user terminal 100 with a touch means, the user terminal 100 can transmit the selection information of the event-executing entity to the receiving terminal 102, and the receiving terminal 102 can execute the operation corresponding to the selection information. Generally, the first image 110 on the receiving terminal 102 may be changed. In this case, if the image 300 of the event-executing entity at the receiving terminal 102 is not changed, the user terminal 100 may maintain the image 302, whereas if the image 300 of the event-executing entity at the receiving terminal 102 is changed, an altered image 302 of the event-executing entity may be shown at the user terminal 100.
  • If a touch means is brought near the display unit of the user terminal 100, the second image 112 or third image 114 may be shown. In particular, if the touch means is positioned over an event-executing entity, event occurrence information can be outputted, for example in the form of a sound, etc. This will be described later in more detail with reference to FIG. 18.
  • In short, embodiments can involve using the user terminal 100 as a means for controlling the receiving terminal 102. This can be particularly efficient for games, electronic commerce, smart V, etc.
  • FIG. 4A and FIG. 4B illustrate a method of linking and controlling terminals according to a third embodiment.
  • Referring to FIG. 4A and FIG. 4B, the image for the second image 112 a indicating the position of the touch means can be changed to a different shape. Also, the second image 112 a can be changed if the touch means is present at a preset position while it is near the user terminal 100 or is touching the user terminal 100 with a pressure or an area smaller than or equal to a preset pressure or area level.
  • For example, if the touch means is not positioned over an event-executing entity, the second image 112 a can be represented as a shadow image as illustrated in FIG. 4A, but if the touch means is positioned over an event-executing entity, it can be represented by a finger image as illustrated in FIG. 4B. The second image 112 can be changed when the touch means is positioned not only over an icon, but also over an Internet address input window, the bottom of the screen, a search window, a folder, and the like.
  • In this case, the receiving terminal 102 can output event occurrence information, such as in the form of sound, light, vibration, etc., according to the event associated with the event-executing entity over which the touch means is positioned. This will be described later in further detail. Changing the second image 112 and outputting the event occurrence information can be performed simultaneously. The method described above can also apply in a similar manner to the third image 114.
  • According to another embodiment, the image 112 or 114 can be changed according to the number of times or the touch duration of the touch means touching the user terminal 100. For example, the image 112 or 114 can be a shadow image when a touch means touches the user terminal 100 once, but can be changed to an arrow image if the touch means makes a touch twice in a row. In another example, the image 112 or 114 can be a shadow image if the touch means touches the user terminal 100 for a duration shorter than or equal to a preset value, and can be changed to a different image if the preset duration is exceeded.
  • In another example, the image 112 or 114 shown when a touch means is near the user terminal 100 can be different from the image 112 or 114 shown when the touch means is touching the user terminal 100.
  • While the second image 112 and the third image 114 can be changed simultaneously, it is also possible to change just one of them or change them into images that are different from each other.
  • The operations of the system for linking and controlling terminals according to an embodiment will be described below in more detail with reference to the accompanying drawings.
  • FIG. 5 illustrates a method of linking and controlling terminals according to a fourth embodiment.
  • Referring to FIG. 5, a user terminal 100 and a receiving terminal 102 may be connected to begin linked operation (S500). To be more specific, if the user terminal 100 or the receiving terminal 102 requests linkage to the counterpart terminal after the user terminal 100 and the receiving terminal 102 connected by the user for linked operation, or if the user terminal 100 requests linkage to the receiving terminal 102 and the linkage is accepted, a channel can be formed between the terminals 100 and 102 capable of transmitting the position information of a touch means. Here, the linkage of the terminals 100 and 102 can be performed according to a user's request or can be performed automatically by a terminal 100 or 102.
  • According to an embodiment, the user terminal 100 and the receiving terminal 102 can be connected by two channels, i.e. a data channel and a control channel, and the control signal for requesting or accepting linkage can be exchanged through the control channel.
  • Next, the receiving terminal 102 may transmit image data corresponding to at least a portion of a first image that is currently being displayed or about to be displayed to the user terminal 100, and the user terminal 100 may display the first image corresponding to the transmitted image data (S502). That is, the user terminal 100 and the receiving terminal 102 may share at least a portion of the first image.
  • Then, when a user brings a touch means, such as a finger or a touch pen, etc., near the user terminal 100 or contacts the touch means with the user terminal 100 with a pressure or an area smaller than or equal to a preset value, then the user terminal 100 may sense the touch means (S504). The user terminal 100 can sense the touch means using various methods such as capacitive sensing, electromagnetic sensing, etc.
  • Next, the user terminal 100 may transmit the position information of the touch means obtained according to the sensing result to the receiving terminal 102, and the receiving terminal 102 may display a second image, which represents the position information of the touch means transmitted thus, together with the first image 110 (S506).
  • According to another embodiment, the user terminal 100 can also transmit image data (or combined image data) that includes data corresponding to the first image and data corresponding to the second image to the receiving terminal 102. However, since this embodiment basically involves the receiving terminal 102 transmitting the image data corresponding to the first image to the user terminal 100, the former method of the user terminal 100 transmitting only the position information to the receiving terminal 102 may be more efficient.
  • Then, when the user makes a touch with or moves the touch means, the user terminal 100 may transmit the position information of the touch means to the receiving terminal 102 to display the second image on the receiving terminal 102 (S508). That is, the movement of the touch means can be reflected on the receiving terminal 102.
  • FIG. 6 illustrates a method of linking and controlling terminals according to a fifth embodiment. FIGS. 7A through 7C illustrate a control method used for the method of linking and controlling terminals in FIG. 6, and FIGS. 8A through 8E illustrate a linking operation when different sensing levels are set in accordance with an embodiment.
  • Referring to FIG. 6, the user terminal 100 or the receiving terminal 102 may request linkage to begin linked operation (S600).
  • According to an embodiment, the user terminal 100 and the receiving terminal 102 can be connected by two channels, i.e. a data channel and a control channel, as illustrated in FIG. 7A, and the control signal for requesting or accepting linkage can be exchanged through the control channel.
  • According to another embodiment, the data can be exchanged through one channel. For example, the transmission periods for the channel can include data periods E1 and E2 for transmitting image data, and a control period C between the data periods E1 and E2 for transmitting the position information or the selection information for an event-executing entity, as illustrated in FIG. 7C. In particular, the position information or selection information can be transmitted by utilizing the blank periods C in-between the periods for transmitting image data. For example, the user terminal 100 can transmit the image data to the receiving terminal 102 through one channel, and can transmit the position information or selection information to the receiving terminal 102 during the blank periods C existing in-between the data periods E1 and E2 for transmitting image data.
  • Next, the receiving terminal 102 may transmit image data corresponding to at least a portion of the first image 110 to the user terminal 100, to thus share the first image 110 with the user terminal 100 (S602).
  • Then, the user terminal 100 may sense the touch pressure or the touch area of the touch means (S604).
  • For example, in sensing the touch pressure or touch area, the user terminal 100 can set multiple levels, e.g. two levels, for the sensing levels, as illustrated in FIG. 7B. If it is not performing a terminal-linked process, i.e. if the user is using only the user terminal 100, the sensing level for the user terminal 100 can be set to a higher level (L2) such that the touch position is sensed only when there is a light touch made by the user.
  • Conversely, if the user is performing a terminal-linked process, i.e. if the receiving terminal 102 is also being used, the user terminal 100 may set the sensing level to a lower level (L1). Thus, the user terminal 100 can sense the touch means even when the touch means is near and not touching or when the touch pressure or touch area is smaller than or equal to a preset pressure or area. In other embodiments, the user terminal 100 can employ various methods other than the capacitance-based method, such as methods based on electromagnetic induction, methods using a resistive overlay, optical methods, ultrasonic methods, etc., and the settings conditions can vary according to the method employed.
  • Next, the user terminal 100 may transmit the position information of the touch means obtained according to the sensing result to the receiving terminal 102, and the receiving terminal 102 may display a second image representing the position information, for example a position image 112 indicating the position of the touch means, such as that illustrated in FIG. 1B, together with the first image 110 (S606).
  • Here, the position information of the touch means can be information in an image form or information in a coordinate form. That is, the user terminal 100 can generate the position information for the second image 112 directly in the form of image data and transmit it to the receiving terminal 102, or transmit only the position information of the touch means to the receiving terminal 102 in the form of a control signal. Alternatively, the user terminal 100 can generate a position image (second image) for of the touch means and transmit image data with the first image and the second image included to the receiving terminal 102, so that the second image 112 can be displayed on the receiving terminal 102 concurrently with the sharing of the first image 110.
  • For example, the position of the touch means can be displayed on the receiving terminal 102 if the touch pressure of the touch means is smaller than or equal to a preset value or the touch area is smaller than or equal to a preset value. That is, if the touch means touches the user terminal 100 lightly, the second image 112 can be displayed on the receiving terminal 102. If the touch means moves while touching the user terminal 100 lightly, the second image 112 may reflect the movement of the touch means, and the second image 112 on the receiving terminal 102 may also move continuously (S608).
  • According to an embodiment, if the touch means touches the user terminal 100 lightly, the user terminal 100 may not recognize the touch of the touch means as a touch input. If the touch means touches the user terminal 100 with a strong pressure, i.e. if the touch pressure exceeds a preset pressure or the touch area exceeds a preset touch area, the user terminal 100 may recognize the touch of the touch means as a touch input. Thus, if the touch means touches the user terminal 100 lightly, the icon may not be executed, but if the touch means touches the icon strongly, the icon can be executed.
  • As described above, the embodiment shown in FIG. 5 and the embodiment shown in FIG. 6 can be applied together. That is, the second image 112 can be displayed on the receiving terminal 102 when the touch means is positioned within a preset distance from the user terminal 100 and when the touch means lightly touches the user terminal 100.
  • Referring to FIGS. 8A to 8E, a more detailed description is provided below on setting the sensing levels for the embodiments illustrated in FIG. 5 and FIG. 6.
  • The user terminal 100 can be set to have multiple sensing levels. For example, a first level, a second level, and a third level can be set at the user terminal 100; a first level for sensing a nearness of a touch means 804, a second level for sensing the touch means 804 touching with a level equal to or smaller than a preset level (pressure level or area level), and a third level for sensing the touch means 804 touching with a level equal to or greater than a preset level.
  • A description is provided below of the operations of the user terminal 100 and the receiving terminal 102 when there are multiple levels set as above.
  • At the receiving terminal 102, the first image 110 can be displayed as illustrated in FIG. 8A. Of course, a first image 110 that is substantially the same can also be displayed at the user terminal 100. The first image 110 can include event-executing entities 800 such as icons, application programs, links, etc., and when an event-executing entity 800 is selected, a racing game, for example, can be executed as illustrated in FIG. 8B. In the descriptions that follow, it will be assumed that the touch position of the touch means 804 corresponds to a particular point on the event-executing entity 800.
  • First, when the touch means 804 is brought near the display unit 806 of the user terminal 100 as illustrated in FIG. 8C, the second image 112 indicating the position of the touch means 804 can be displayed on the receiving terminal 102 as illustrated in FIG. 8A. In addition, the third image 114 can also be shown on the user terminal 100.
  • Next, if the touch means 804 touches the display unit 806 with a level smaller than or equal to a preset level as illustrated in FIG. 8D, the image 112 or 114 indicating the position of the touch means 804 can remain as is, and the event-executing entity 800 may remain unexecuted.
  • If the touch means 804 touches the display unit 806 with a level greater than or equal to the preset level as illustrated in FIG. 8E, the user terminal can recognize this as a selection of the event-executing entity 800 and execute the game. The distal end 810 of the touch means 804 can be structured such that it can be inserted inside, and when the user makes a touch with the touch means 804 with a level greater than or equal to a preset level, the display unit 806 may be pressed with the distal end 810 inserted inside, as illustrated in FIG. 8E.
  • In short, a linkage and control system based on this embodiment can perform different operations according to sensing levels.
  • In another embodiment, if the touch means 804 is brought near, an image 112 or 114 indicating the position of the touch means 804 can be shown, and if the touch means 804 touches the display unit 806, the event-executing entity 800 can be executed.
  • FIG. 9 is a flowchart illustrating a method of linking and controlling terminals according to a sixth embodiment.
  • Referring to FIG. 9, the user terminal 100 and the receiving terminal 102 may begin linked operation (S900).
  • Next, the receiving terminal 102 may transmit image data corresponding to at least a portion of the displayed first image to the user terminal 100, and the user terminal 100 may display a first image corresponding to the image data (S902). That is, the user terminal 100 and the receiving terminal 102 may share the first image.
  • Then, the user terminal 100 may sense a touch means, such as a finger, a touch pen, etc., through any of a variety of methods (S904). The user terminal 100 can sense the position of a touch means that is near the user terminal 100 or lightly touching the user terminal 100.
  • Next, the user terminal 100 may generate a combined image, including the currently displayed first image together with the second image corresponding to the sensed position of the touch means, and may transmit combined image data (combination information) corresponding to the combined image to the receiving terminal 102, and the receiving terminal 102 may display the combined image corresponding to the combined image data (S906). Consequently, the second image together with the first image may be displayed on the receiving terminal 102. In this case, the user terminal 100 can display the first image only or display the first image and the second image together.
  • If the user makes a touch with the touch means or moves while touching, the user terminal 100 may transmit the position information of the touch means to the receiving terminal 102, and the receiving terminal 102 may display the second image, which indicates the position of the touch means in accordance with the position information, together with the corresponding first image (S908). That is, the movement of the touch means may be reflected in the screen of the receiving terminal 102. The first image on the receiving terminal 102 may be the same image as the previous image or may be a different image from the previous image.
  • In short, this embodiment has the user terminal 100 generate a combined image that includes the first image and the second image and transmit the combined image thus generated to the receiving terminal 102, so that the receiving terminal 102 may consequently display the second image together with the first image.
  • Although the descriptions above use the expression “combined image,” it is possible to modify the first image itself such that the first image indicates the position of the touch means. To be more specific, the user terminal 100 can modify the first image such that a region corresponding to the position of the touch means is changed to a shadow image, etc., that is, the first image itself can be modified to create a new image, after which the image thus created can be transmitted to the receiving terminal 102. Here, the modified first image can be substantially the same as the combined image.
  • FIG. 10 is a flowchart illustrating a method of linking and controlling terminals according to a seventh embodiment.
  • Referring to FIG. 10, the user terminal 100 and the receiving terminal 102 may begin linked operation (S1000).
  • Next, the user or the user terminal 100 may set multiple sensing levels for sensing the touch means (S1002). As described above, various levels can be set for different embodiments. Such settings may be established at the beginning of the linked operation or may be established beforehand in the user terminal 100 prior to linked operation.
  • Then, the user terminal 100 may sense the touch means, and the receiving terminal 102 may display the second image, which represents the sensed position of the touch means (S1004).
  • Next, it may be determined whether or not there was a request by the user to stop linked operation (S1006). The stopping of linked operation can be requested by the user by a method such as a menu selection, etc., or can also be requested by turning off the connection between the user terminal 100 and the receiving terminal 102. The user, controlling the user terminal 100 while viewing the receiving terminal 102, may wish to use the user terminal 100 only or may wish to view the receiving terminal 102 only, in which case the user can request for a stopping of linked operation while the user terminal 100 and the receiving terminal 102 are in a connected state.
  • If there is no request from the user to stop the linked operation, then step S1004 may be performed again.
  • Conversely, if there is a request from the user to stop linked operation, then the user terminal 100 may initialize the multiple levels such that only one level is available or change the levels to sensing levels which only sense touches (S1008). That is, the user terminal 100 may change the levels such that the touch means is not sensed if the touch means does not make a touch, and that the touch means is sensed only when the touch means makes a touch.
  • In short, a method of linking and controlling terminals according to an embodiment can allow a user to arbitrarily request linked operation and request a stopping of the linked operation and to freely set and change sensing levels.
  • According to another embodiment, a preliminary sensing level can be set at the beginning of linked operation between the user terminal 100 and receiving terminal 102, and the sensing levels can be set differently during linked operation. For example, the user can set different sensing levels during linked operation according to the nearness distance and touch strength of the touch means and can change the sensing level settings to sense the touch means only when it is in contact.
  • FIG. 11 illustrates a system for linking and controlling terminals according to another embodiment.
  • Referring to FIG. 11, a system for linking and controlling terminals based on this embodiment can include a user terminal 100, a receiving terminal 102, and a transceiver device 1100 (e.g. a dongle).
  • The transceiver device 1100 can connect the communications between the user terminal 100 and the receiving terminal 102. To be more specific, when the user terminal 100 transmits the position information of a touch means, the combined image data, or the selection information for an event-executing entity to the transceiver device 1100, the transceiver device 1100 can transmit the position information of the touch means, the combined image data, or the selection information for the event-executing entity to the receiving terminal 102. Also, image data transmitted from the receiving terminal 102 can be transmitted by the transceiver device 1100 to the user terminal 100.
  • The transceiver device 1100 can be connected to the user terminal 100 or the receiving terminal 102, or can exist separately without being connected to the user terminal 100 and receiving terminal 102. The transceiver device 1100 can be, for example, a dongle, a set-top, etc.
  • According to an embodiment, the position information, combined image data, or selection information transmitted from the user terminal 100 can be forwarded by the transceiver device 1100 as is, without modification, to the receiving terminal 102.
  • According to another embodiment, the transceiver device 1100 may convert the position information, combined image data, or selection information transmitted from the user terminal 100 to a format suitable for the receiving terminal 102 and then transmit the converted position information or combined image data to the receiving terminal 102. Since many companies currently manufacture the receiving terminal 102, in the form of a smart TV, etc., it may be necessary to match the position information, combined image data, or selection information with the format of the receiving terminal 102 according to manufacturer. An embodiment can use the transceiver device 1100 to convert the position information, combined image data, or selection information to fit the format of the receiving terminal 102, so that the terminals 100 and 102 can be linked regardless of manufacturer.
  • Although it is not illustrated in the drawings, the transceiver device 1100 can include a communication unit, a signal unit, and a format changer unit.
  • The communication unit may connect the user terminal 100 and the receiving terminal 102.
  • The signal unit can transmit to the receiving terminal 102 the position information of the touch means, the combined image data, or the selection information transmitted from the user terminal 100, and can transmit the first image received from the receiving terminal 102 to the user terminal 100.
  • The format changer unit can modify the position information, combined image data, or selection information to the format of the receiving terminal 102 or modify the first image to the format of the user terminal 100.
  • In short, the user terminal 100 and the receiving terminal 102 can send or receive the position information, image data, combined image data, or selection information by way of the transceiver device 1100. In this case, the user terminal 100 or the receiving terminal 102 connected to the transceiver device 1100 need not have a communication function.
  • According to another embodiment, the transceiver device 1100 may not only provide communication between the user terminal 100 and the receiving terminal 102 but may also sense the position of a touch means 1102.
  • According to yet another embodiment, the transceiver device 1100 may serve as a communication means for the user terminal 100 and can provide a particular communication function, such as Wibro communication, for example, and can also convert a particular communication function into another communication function, such as by converting Wibro to Wi-Fi, for example, for use by the user terminal 100.
  • FIG. 12 is a flowchart illustrating a method of linking and controlling terminals according to an eighth embodiment.
  • Referring to FIG. 12, a receiver may be installed on the receiving terminal 102 (S1200). In another embodiment, the receiver can be built into the receiving terminal 102.
  • Next, the user terminal 100 and the receiving terminal 102 may begin linked operation (S1202).
  • Then, the user terminal 100 may transmit image data corresponding to the first image to the receiving terminal 102 to share the first image 110, or the receiving terminal 102 may transmit the image data to the user terminal 100 to share the first image 110 (S1204).
  • Next, when a touch means is brought near the user terminal 100 or touches the display unit of the user terminal 100 with a pressure or an area smaller than or equal to a preset pressure or preset area, the receiver may sense the position of the touch means by way of infrared rays and ultrasonic waves emitted from the touch means and transmit the sensed position of the touch means to the receiving terminal 102, and the receiving terminal 102 may display the second image, which represents the position thus obtained by sensing, together with the first image (S1206).
  • Then, the user terminal 100 may transmit the position information based on the movement of the touch means to the receiving terminal 102, and the receiving terminal 102 can show the movement of the touch means as a second image 112 or a third image different from the second image.
  • Various methods for sensing a touch means will now be described in more detail with reference to the accompanying drawings.
  • FIG. 13 illustrates a method of sensing a touch means according to a first embodiment.
  • Referring to FIG. 13, a touch pen 1300 can be used as the touch means intended for touching the user terminal 100. A capacitance-based touch panel may be used for the user terminal 100.
  • The touch pen 1300 may be composed of a body 1310 and a touch part 1312. The body 1310 may be made of an electrically non-conducting material, while the touch part 1312 may be a conductor. Thus, because of the touch part 1312, a change in capacitance may occur when the touch pen 1300 is brought near the user terminal 100 or is touching the user terminal 100, and the user terminal 100 can sense the touch pen 1300 based on the change in capacitance.
  • FIG. 14 illustrates a method of sensing a touch means according to a second embodiment.
  • Referring to FIG. 14, the user terminal 100 can include a touch panel 1400 and an electromagnetic field generator unit 1402.
  • The electromagnetic field generator unit 1402 can be connected to a rear surface of the touch panel 1400 and can be made of a thin metal film to generate an electromagnetic field when electricity is applied.
  • The touch pen 1404 may include a body 1410 and a touch part 1412, where the touch part 1412 can preferably be made of a small metal coil. Consequently, when the touch pen 1404 is brought near the touch panel 1400, electromagnetic induction may occur in the touch part 1412, and as a result, an alteration may occur in the electromagnetic field created by the electromagnetic field generator unit 1402. Thus, the user terminal 100 may recognize the position of the touch pen 1404 by sensing this alteration in the electromagnetic field. In particular, since the alteration of the electromagnetic field would differ according to the nearness and touch strength of the touch pen 1404, this method of sensing the touch means can minutely sense the degree of proximity and the touch pressure of the touch pen 1404 with respect to the touch panel 1400.
  • FIG. 15A and FIG. 15B illustrate a method of sensing a touch means according to a third embodiment.
  • Referring to FIG. 15A, a receiver 1500 can be installed on a portion of the user terminal 100, and a touch pen 1502 can be used.
  • The receiver 1500 can include an infrared sensor and two ultrasonic sensors to sense the movement of the touch pen 1502 by receiving the infrared rays and ultrasonic waves emitted from the touch part (pen tip) of the touch pen 1502, and can transmit the position information of the touch pen 1502 obtained in accordance with the sensing results to the receiving terminal 102. The receiving terminal 102 may display a second image that represents the transmitted position information. Consequently, the second image may be displayed together with the first image. Here, the position information can be transmitted to the receiving terminal 102 by the receiver 1500 or by the user terminal 100.
  • According to another embodiment, the receiver 1500 can perform not only the function of sensing the position of the touch pen 1502 but also the function of transmitting image data and position information to the receiving terminal 102. To be more specific, the receiver 1500 can include a touch control unit 1510, an image signal unit 1512, a control signal unit 1514, and a transceiver unit 1516, as illustrated in FIG. 15B.
  • The touch control unit 1510 may serve to sense the position of the touch pen 1502 by using the received infrared rays and ultrasonic waves and provide the user terminal 100 with the information on the sensed position. The user terminal 100 may show the position of the touch pen 1502 or perform a related operation in accordance to the information thus provided.
  • The image signal unit 1512 can be provided with image data from the user terminal 100 and transmit the image data thus provided to the receiving terminal 102 via the transceiver unit 1516.
  • The control signal unit 1514 may serve to transmit a control signal, which includes the position information of the touch pen 1502 obtained above by sensing, to the receiving terminal 102. That is, since the receiver 1500 transmits the image data transmitted from the user terminal 100 and the position information of the touch pen 1502 to the receiving terminal 102, the user terminal 100 does not have to include a communication function. Therefore, even with a terminal that does not have a communication function or a terminal that has a communication function but is unable to use the related communication facilities, it is possible to recognize the position and action of the touch pen 1502 using the receiver 1500 as well as to employ a linkage method according to an embodiment for sharing images, displaying the second image, etc.
  • In another embodiment, the receiver can be incorporated into the user terminal 100 to be implemented as a single body.
  • FIG. 16A and FIG. 16B illustrate a method of sensing a touch means according to a fourth embodiment.
  • Referring to FIG. 16A, in a system for linking and controlling terminals according to an embodiment, a receiver 1600 can be installed on or built into the receiving terminal 102 rather than the user terminal 100.
  • When a touch pen 1602 serving as the touch means for the user terminal 100 emits ultrasonic waves and infrared rays to the receiver 1600 installed on the receiving terminal 102, the receiver 1600 may receive the ultrasonic waves and infrared rays to sense the position of the touch pen 1602.
  • The receiver 1600 may transmit information regarding the position of the touch pen 1602 thus sensed to the receiving terminal 102, and the receiving terminal 102 may display the second image representing the position of the touch pen 1602 together with the first image. Of course, the user terminal 100 and the receiving terminal 102 may display the second image while sharing the first image.
  • According to another embodiment, the receiver 1600 can serve not only to sense the position of the touch pen 1602 but also to perform communication. To be more specific, the receiver 1600 can include a touch means sensing unit 1610, an image signal unit 1612, a control signal unit 1614, and a transceiver unit 1616.
  • The touch means sensing unit 1610 may serve to sense the position of the touch pen 1602.
  • The image signal unit 1612 may receive the combined image data transmitted from the user terminal 100 by way of the transceiver unit 1616 and transmit the received image data by way of the transceiver unit 1616 to the receiving terminal 102, or may also receive image data from the receiving terminal 102 and transmit the received image data to the user terminal 100.
  • The control signal unit 1614 can receive a control signal transmitted from the user terminal 100 related to the linked operation, etc., and can transmit the received control signal to the receiving terminal 102. Of course, the position information of the touch pen 1602 need not be transmitted from the user terminal 100 to the receiver 1600. As such, the receiver 1600 may provide not only the function of sensing the position of the touch pen 1602 but also a communication function. Thus, a linking and control method according to an embodiment can be used even when the receiving terminal 102 does not have a communication function.
  • FIG. 17 is a block diagram illustrating the structure of a user terminal according to an embodiment.
  • Referring to FIG. 17, the user terminal 100 of this embodiment can include a control unit 1700, a linkage unit 1702, an image unit 1704, a control unit 1700, a linkage unit 1702, an image unit 1704, a sensing unit 1706, a settings unit 1708, a display unit 1710, a signal unit 1712, a transceiver unit 1714, a decoding unit 1716, and a storage unit 1718.
  • The linkage unit 1702 may manage all functions related to linkage with the receiving terminal 102.
  • The image unit 1704 can include an image generator unit and an image changer unit and can display, via the display unit 1710, an image corresponding to the image data transmitted from the receiving terminal 102.
  • The image generator unit can generate a position image, which may represent the position of a touch means that is positioned within a preset distance from the display unit 1710, generate a combined image, which may include the second image and the first image, or generate a position image of a touch means that is touching the display unit 1710 with a pressure or an area smaller than or equal to a preset value.
  • The image changer unit can change the position image according to the distance between the touch means and the user terminal 100, and can change the position image according to the pressure or area with which the touch means contacts the user terminal 100. Also, the image changer unit can change the position image according to whether or not the touch means is over an event-executing entity or a preset position.
  • The sensing unit 1706 may serve to sense a touch means, such as a finger or a touch pen, etc. More specifically, the sensing unit 1706 can sense the position of the touch means, distinguishing when the touch means is near and when it is touching. The method of sensing is not limited to a particular method and can be a capacitance-based method, an electromagnetic induction-based method, etc. The information on the position of the touch means as sensed by the sensing unit 1706 can also be generated by a position information generating unit (not shown).
  • The settings unit 1708 may manage the settings of various functions, such as linkage function settings, sensing level settings, etc.
  • The display unit 1710 can be implemented in various ways such as by using capacitance-based types, resistive overlay types, electromagnetic induction types, etc. The display unit 1710 can be a touch display unit equipped with a touch function.
  • The signal unit 1712 can include an information transmitting unit 1720 and an information receiving unit 1722.
  • The information transmitting unit 1720 can transmit the position information of a touch means or the selection information for an event-executing entity to the receiving terminal 102. The selection information can include position information corresponding to a touch input for selecting an event-executing entity or control information for executing an event-executing entity according to a touch input.
  • The information receiving unit 1722 may receive image data from the receiving terminal 102 corresponding to the entirety or a portion of the first image.
  • The transceiver unit 1714 may serve as a communication passageway to the receiving terminal 102.
  • The decoding unit 1716 may decode the image data received from the receiving terminal 102.
  • The storage unit 1718 may store various data, such as the first image, image signals, position information, control signals, application programs, etc.
  • The control unit 1700 may control the overall operations of the components of the user terminal 100.
  • Although it has not been described above, the user terminal 100 can further include a touch means unit, a receiver unit, an electromagnetic field generator unit, or a touch means operating unit.
  • The touch means unit may receive and manage information on the position of the touch means when the receiver is connected with the user terminal 100. That is, the receiver may sense the position of the touch means, while the touch means unit may analyze the signals transmitted from the receiver to detect the position of the touch means.
  • The receiver unit may receive infrared rays and ultrasonic waves transmitted from the touch means when the touch means is brought near to or in contact with the user terminal 100, and may analyze the infrared rays and ultrasonic waves thus received to detect the position of the touch means.
  • The electromagnetic field generator unit may serve to create an electromagnetic field for sensing the touch means by electromagnetic induction, and may preferably be formed on a rear surface of the display unit.
  • The touch means operating unit can perform a particular operation when the touch means is brought near the user terminal 100 or is touching the user terminal 100 with a pressure or an area smaller than or equal to a preset value. For example, a scroll function can be performed if the touch means is brought near a lower part of the display unit 1710 on the user terminal 100. In this case, the position information of the touch means can be transmitted to the receiving terminal 102 or a third image 114 corresponding to the position information can be displayed on the display unit 1710. That is, the user terminal 100 can transmit the position information of the touch means or display a third image 114 on the user terminal 100, in response to an approaching near of or a light touch by the touch means, to result in a particular operation such as scrolling, etc.
  • FIG. 18 is a block diagram illustrating the structure of a user terminal according to another embodiment.
  • Referring to FIG. 18, the user terminal 100 of this embodiment can include a control unit 1800, a display unit 1802, a sensing unit 1804, a signal unit 1806, an image unit 1808, an information provider unit 1810, and a mode changer unit 1812. The user terminal 100 can include all or just some of the components above. Also, the user terminal 100 can additionally include components other than the components above.
  • The display unit 1802 may display a first image that is shared by the user terminal 100 and the receiving terminal 102. Also, the display unit 1802 can display a menu, etc., from which to select a touch mode.
  • The sensing unit 1804 may sense the position of a touch means by way of various methods such as those described above, when the touch means is near or is touching the user terminal 100. Here, the position information representing the position of the touch means can be the position information of the touch means that is positioned within a preset distance from the user terminal 100.
  • The signal unit 1806 may transmit the position information of the touch means obtained by the sensing above to the receiving terminal 102 and may transmit image data corresponding to the first image shared by the user terminal 100 and the receiving terminal 102 to the receiving terminal 102.
  • The image unit 1808 may generate combined image data that is to be shared by the user terminal 100 and the receiving terminal 102 or the second image that indicates the position of the touch means.
  • The information provider unit 1810 can output information according to the sensing results of the sensing unit 1804. That is, nearness information can be outputted if a touch means is brought near the user terminal 100 and sensed by the sensing unit 1804. The nearness information can be in the form of vibration, sound, or light, so as to stimulate the user's tactile, auditory, or visual senses.
  • The information provider unit 1810 can provide the user with a tactile, auditory, or visual sensation in various types according to the state of nearness of the touch means with respect to the user terminal 100, to allow the user of the user terminal 100 to perceive various tactile, auditory, or visual sensations.
  • For example, with the user terminal 100 having recognized a near touch of the touch means, the information provider unit 1810 can provide a continuous vibration, sound, or light during a movement of the touch means. That is, a short vibration can be provided once when a near touch of the touch means is first recognized, after which continuous vibrations can be provided when the touch means moves. In other words, when a near touch of the touch means is first recognized, a vibration can be provided for a first duration, and afterwards when the touch means moves, a vibration can be provided for a second duration. Here, the second duration can be longer than the first duration.
  • Alternatively, the information provider unit 1810 can provide a vibration when a near touch is first recognized, and afterwards provide a sound when the touch means is moving.
  • In another example, the information provider unit 1810 can provide the user with nearness information in the form of sound, etc., when the touch means is brought near a preset entity such as a folder, control UI, etc., from among the images shown on the screen of the user terminal 100. That is, as described above with reference to FIGS. 6A and 6B, the position image of the touch means can change when the touch means is placed at a preset position, and at this time, the information provider unit 1810 can output nearness information, where the nearness information can correspond to event occurrence information. In this way, the user can perceive the entity immediately.
  • The information provider unit 1810 can provide the nearness information for a first duration when the sensing unit 1804 recognizes a nearness state of the touch means, and can provide the nearness information for a second duration when the touch means moves while the sensing unit 1804 is aware of the nearness state of the touch means. The second duration can be a duration corresponding to the duration for which the touch means moves while the sensing unit 1804 is aware of the nearness state of the touch means.
  • Also, the information provider unit 1810 can provide the nearness information in different forms for a first case in which the sensing unit 1804 recognizes a nearness state of a touch means and a second case in which the touch means is moved while the sensing unit 1804 is aware of the nearness state of the touch means. As described above, a vibration can be provided for the first case and a sound can be provided for the second case, or vibrations of a first pattern can be provided for the first case and vibrations of a second pattern can be provided for the second case, so as to allow the user to perceive the movement of the touch means.
  • If the touch means touches the display unit 1802 after the sensing unit 1804 has recognized a nearness state, the information provider unit 1810 may not provide the nearness information, allowing the user of the user terminal to differentiate between a near state and a direct touch.
  • After the touch means has touched the display unit 1802, if the sensing unit 1804 recognizes a nearness state of the touch means for a second time, the information provider unit 1810 can provide the nearness information. Once the touch means is brought near the user terminal 100 and touches the user terminal 100, the touch means may be separated from the user terminal 100. That is, since the purpose of the touch has been fulfilled, the touch means may be separated from the user terminal 100 to proceed with the next operation, at which time a nearness state may occur again. In this case, since the touch means is put in a nearness state for the first time after touching the display unit 1802 and was not intentionally placed in a nearness state by the user, the information provider unit 1810 may not provide nearness information. Then, when a nearness state occurs for the second time, i.e. the user intentionally triggers a nearness state, the information provider unit 1810 can provide nearness information.
  • The mode changer unit 1812 may change the touch mode according to the user's input, where the touch mode can include a near touch mode 1820 and a direct touch mode 1822. Here, the user input can be made by way of a switch. The switch can be configured as a ring/vibration conversion switch.
  • In the near touch mode 1820, the position image of a nearby touch means can be displayed on the user terminal 100 or the receiving terminal. Also, the position image of a touch means touching the user terminal 100 with a pressure level or area smaller than or equal to a preset value can be displayed on the user terminal 100 or the receiving terminal.
  • In the near touch mode, the user terminal 100 may recognize the position of a touch means that is near the user terminal 100 for a touch input of the touch means, and in the direct touch mode, the user terminal 100 may recognize a touch by the touch means as a touch input.
  • According to an embodiment, the mode changer unit 1812 can change the touch mode at the beginning of linked operation between the user terminal 100 and the receiving terminal 102 or change the touch mode according to the user's command, e.g. the user's touch, voice data, or visual data. For example, the user can change the touch mode by selecting on a menu shown on the user terminal 100, or the touch mode can be changed by the user's voice or a visual sequence such as motion.
  • The touch mode change function described above can be provided when the linked operation of the user terminal 100 and the receiving terminal 102 begins, or can be provided in the user terminal 100 regardless of linked operation. Also, the touch mode change function for linked operation can be provided automatically when the linked operation begins or can be provided after linking when the user selects the function. With a small screen as on a smart phone, it can be useful to sense a touch means that is nearby and show a corresponding image on the smart phone, and in such a device, it may be advantageous to provide the touch mode change function regardless of linked operation.
  • According to another embodiment, the user terminal 100 can be provided with a link mode in addition to the near touch mode and direct touch mode. For example, if a user carrying a user terminal 100 such as a smart phone or a tablet PC, etc., wishes to link it to a receiving terminal 102, the user can select the link mode. When the user selects the link mode, the user terminal 100 can search for display apparatuses close by, begin linking with a searched receiving terminal 102, and display a menu from which to select a near touch mode and a direct touch mode on the user terminal 100 at the beginning of the linked operation.
