1 is a diagram illustrating an embodiment of a system for sharing an input device according to the present invention. As shown in FIG. 1, a system sharing an input device includes an input device 300, a first terminal 100 receiving an input signal from the input device 300, and a signal received by the first terminal 100. It includes a second terminal 200 to share the input signal. In FIG. 1, one second terminal 200 is illustrated, but there may be a plurality of second terminals.

The input device 300 may be at least one of a touch pad, a mouse, a keyboard, a joystick, a pointing stick, and a trackball. A touchpad is a finger pointing a flat sensor and is one of the pointing devices for operating a mouse pointer. Depending on the maker, it is also called a slide pad or a track pad. A joystick is also one of the computer's input devices, called the controller of the game, which uses the axis to enter direction, and often has a push button that reads the status on a personal computer when controlling a video game. I have over. The pointing stick is one of the pointing devices employed in notebook computers, and the trackball is a kind of pointing device used to control a computer such as a mouse.

The present invention is to share and use the above-described input device between the terminal device, as an embodiment of a method of sharing the input device, the second terminal 200 automatically searches for the first terminal 100 You can request a connection. Therefore, in order to automatically search and connect the first terminal 100, the second terminal 200 may use an identification number and a location for identifying the first terminal 100.

Accordingly, the second terminal 200 is a first communication capable of communicating using at least one of an IP address (Internet Protocol address), an access point (AP), a medium access control address (MAC address), and a global positioning system (GPS). The terminal 100 may be selected.

An Internet Protocol address, or Internet Protocol address, is a special number that devices use to recognize and communicate with each other in a computer network. Every device on your network, whether it's a router or a regular server, must have this special number. Therefore, the second terminal 200 may transmit the access request signal by searching for the first terminal 100 using a specific IP address. The specific IP address may be an IP address of the first terminal 100 or may be an IP address of an access point (AP) installed near the first terminal 100 and connected to the first terminal 100. .

The AP is one of the devices constituting the wireless LAN and connects the wired LAN to the wireless LAN. An AP is usually a standalone device that plugs into an Ethernet hub or server and often uses a designated IP address.

However, in general, the IP address may change, and thus may not always be able to connect to a specific terminal device. Therefore, in such a case, it is necessary to select a specific terminal device, that is, the first terminal 100 by using an additional identification number or location. Accordingly, the first terminal 100 may be selected using at least one of a media access control address (MAC address) and a global positioning system (GPS) in addition to the IP address.

The media access control address (MAC address) is a semi-unique identifier attached to most network adapters (NICs) in computer networking. It is a number that acts like the name of a particular network adapter. That is, the MAC address is a unique value of the device. Accordingly, the access request signal may be transmitted to the first terminal 100 using the IP address of the AP and the MAC address of the first terminal 100.

The GPS (Global Positioning System), or satellite positioning system, is a satellite navigation system that receives signals from GPS satellites and calculates the user's current location. It is mainly used for navigation devices such as aircraft, ships, and automobiles, and recently, GPS receivers are also widely used in smartphones and tablet PCs. Accordingly, the access request signal may be transmitted from the second terminal 200 to the first terminal 100 using a location based services (LBS) combining the wireless Internet and the GPS.

As described above, the combination of the IP address, the MAC address, and the GPS may be used to automatically access the first terminal 100 designated by the second terminal 200. In particular, it is particularly useful to designate a computer of a company and a home which are often used together with a computer and a smart phone as the first terminal 100 and use a smart phone as the second terminal 200. Most homes and businesses designate a desktop computer or laptop, and they always have their own smartphones, so when they arrive at home or work, they automatically connect to a personal desktop computer or laptop at home or work. To share the input device. Accordingly, the user can easily operate by using a mouse or a keyboard without having to separately operate a smart phone during work, thereby maximizing user convenience.

When the first terminal 100 receives a connection request signal, the first terminal 100 transmits the input signal to the second terminal 200 when an input signal occurs within a predetermined area on the screen. This may be described later with reference to FIG. 7.

The second terminal 200 receiving the input signal may convert the received input signal into a control signal that can be recognized by the second terminal 200. In the case of a terminal device that cannot connect and use an input device such as a mouse such as a smart phone or a smart TV, even if an input signal of the input device is received, the terminal device cannot be controlled according to the input signal. Thus, in this case, the input signal can be converted into a control signal that can be recognized.

For example, it is assumed that a computer is a first terminal 100, a smartphone is a second terminal 200, and the input device 300 connected to the first terminal 100 is a mouse. When the second terminal 200 receives an input signal generated by the input device 300, the second terminal 200 may convert the input signal into a control signal by converting a mouse event into a touch event. Through this conversion process, the input device can be shared and the second terminal 200 can be controlled using the shared input device.

FIG. 2 is a functional block diagram of a system for sharing an input device according to an embodiment of the present invention. Referring to FIG. 2, a system for sharing an input device will be described in detail. However, FIG. 2 is an embodiment for describing the present invention, and some component modules may be deleted or new component modules may be added according to the needs of those skilled in the art.

As shown in FIG. 2, the first terminal 100 may include a user interface 110, a sharing setting unit 120, a controller 130, and an external device interface 140, and an input device 300. It is connected by wire and wireless.

The user interface 110 receives an input signal from the input device 300, which has been described above as at least one of a touch pad, a mouse, a keyboard, a joystick, a pointing stick, and a trackball.

In addition, the user interface 110 transmits an input signal of the input device 300 by the user to the controller 130 or transmits a signal from the controller 130 to the user. Accordingly, a secondary cursor is added to the input device corresponding to the pointing device such as a mouse to show the user the position of the input device pointer, and blinking underline or vertical line for the input device such as a keyboard is input. Character cursors and the like can be provided to the user.

The sharing setting unit 120 may set whether to share an input signal received from the input device 300 with an external device. Therefore, the input signal is transmitted to the second terminal 200 only when the sharing setting unit 120 decides to share the input signal of the input device 300.

In order to set whether to share the input signal of the input device 300 in the sharing setting unit 120, a menu that can be set by a user through an application installed in the first terminal 100 may be provided.

The controller 130 may determine whether an input signal is generated within a predetermined area on a screen corresponding to the connection request signal when the sharing setting unit 120 sets sharing.

Even when the sharing setting unit 120 is set to share, it is necessary to set a criterion whether the input signal of the input device operates in the first terminal 100 or the second terminal 200. Accordingly, the controller 130 sets a specific area on the screen and transmits an input signal to the second terminal 200 when an input device corresponding to the pointing device such as a mouse generates a signal in a specific area. Control device interface 140.

For example, the controller 130 sets a portion that enters the center of a certain portion from the edge on the screen as a specific region, and transmits the input signal to the second terminal 200 when the mouse clicks or drags in the specific region. The external device interface 140 is controlled. This will be described later with reference to FIG. 7.

The external device interface 140 may be connected to an external device and a network device, and for this purpose, may include an A / V input / output unit (not shown) or a wireless communication unit (not shown). In addition, for connection with a wired network, an Ethernet terminal may be provided, for example, and for connection with a wireless network, for example, a wireless LAN (WLAN) (Wi-Fi), Wibro (Wireless). Broadband, World Interoperability for Microwave Access (Wimax), High Speed Downlink Packet Access (HSDPA) communication standards, and the like can be used. Accordingly, the external device interface 140 may transmit the received input signal to the second terminal 200 under the control of the controller 130.

In addition, the external device interface 140 may receive an application or a list of applications in a neighboring external device and transmit the received application to the controller 130. You can choose to receive it.

The second terminal 200 may include a terminal selector 210, a communicator 220, a signal converter 230, and a memory 240.

The terminal selector 210 may select a first terminal that can communicate using at least one of an Internet Protocol address, a Media Access Control Address, and a Global Positioning System (GPS).

The IP address may be an IP address of the first terminal 100 or an IP address of an access point (AP) installed in the vicinity of the first terminal 100 and connected to the first terminal 100. If the first terminal 100 uses only a specified IP address, the terminal may be selected using only an IP address. However, if the first terminal 100 does not use a designated IP address, the location-based service (LBS; Location Based Services) may be used to select the first terminal 100.

When the communication unit 220 selects the first terminal 100 in the terminal selection unit 210, the communication unit 220 transmits a connection request signal to the first terminal. When the connection is successful, the communication unit 220 receives the first terminal 100 from the first terminal 100. 1 An input signal of the input device 300 connected to the terminal 100 may be received.

The communication unit 220 may use wired or wireless communication to transmit and receive a connection request signal and an input signal with the first terminal, but is not limited to a specific communication method. However, since the first terminal and the second terminal are often located at a short distance, Wi-Fi, Bluetooth, and ZigBee communication, which are short-range communication, may be used.

The signal converter 230 may convert an input signal received through the communication unit 220 into a control signal recognizable by the second terminal 200. That is, when the second terminal 200 is not provided with a module for controlling the input signal from the keyboard, mouse, etc., the signal conversion unit 230 may recognize the input signal in the second terminal 200. To convert the signal so that.

For example, a mouse event, which is a received input signal, may be converted into a touch event that can be recognized by the second terminal 200, or a keyboard event, which is a received input signal, may be recognized for a key value of the virtual keyboard that can be recognized by the second terminal 200. To convert it into a signal.

To this end, the memory 240 may store a matching table of an input signal and a control signal. In addition, the memory 240 may store at least one of a predetermined IP address, a media access control address, and a global positioning system (GPS) in order to select a first terminal that can communicate.

3 is a diagram illustrating an embodiment of sharing a keyboard between terminal devices according to the present invention. As shown in FIG. 3, a user may need to perform a real-time conversation using a smart phone, which is the second terminal 200, while working on a document using a desktop computer, which is the first terminal 100. In this case, when the input device is shared between the first terminal 100 and the second terminal 200 according to the present invention, the user does not need to separately operate the smartphone by using the virtual keyboard of the smartphone. You can create a message using the keyboard connected to 100) to have a real-time conversation. As described above, the user can directly operate the smart phone using the input device used during the computer work, thereby minimizing the interruption of the work process.

4 is a diagram illustrating an embodiment of sharing a mouse between terminal devices according to the present invention. While the user performs a specific task by using the desktop computer, which is the first terminal 100, the user searches for specific information by using the smart phone, which is the second terminal 200, receives a call, or rejects an incoming call. Sometimes you need to do something else.

Substantially, it is possible to operate the smart phone with a simple touch, but there is a need to stop using the first terminal 100 and to operate the smart phone. Accordingly, when the first terminal 100 and the second terminal 200 share the input device 300 according to the present invention, as shown in Figure 4, the mouse used in the first terminal 100 The pointer 400 may be moved to the second terminal 200 to perform a task. As such, there is an advantage in that it is possible to perform necessary tasks much more easily and quickly than performing a separate touch to operate a smart phone.

5 is a flowchart illustrating a data transmission protocol between terminal devices sharing an input device according to an embodiment of the present invention, and illustrates a data transmission protocol between a first terminal and a second terminal.

The first terminal sets to share the input signal received from the external device and the input device (S500).

When it is necessary to use the input device, the second terminal selects a first terminal that can communicate (S510), and transmits a connection request signal to the first terminal (S520). In this case, the method of selecting the first terminal capable of communication may be to select an arbitrary terminal to which a signal capable of communication can be selected, or to select a specific terminal using an IP address, a MAC address, and a GPS.

When the first terminal receives an input signal from the input device (S530), it is determined whether the input signal is generated within a predetermined area on the screen (S540). A specific area is set on the screen and an input signal is transmitted to the second terminal when an input signal occurs within the specific area (S550). The second terminal receiving the input signal converts the input signal into a control signal recognizable by the second terminal (S560).

Up to now, selecting the first terminal to share the input device in the second terminal has been described as an embodiment of the present invention. Hereinafter, as another embodiment of the present invention, the first terminal selects a second terminal to share the input device will be described. However, detailed description of the same and similar parts as described above will be omitted.

6 is a functional block diagram of a terminal device sharing an input device according to an embodiment of the present invention. Referring to FIG. 6, a first terminal according to another embodiment will be described. However, FIG. 2 is an embodiment for describing the present invention, and some component modules may be deleted or new component modules may be added according to the needs of those skilled in the art.

As illustrated in FIG. 6, the terminal device 600 sharing the input device includes a user interface 610, a controller 620, an external device interface 630, a sharing setting unit 640, and a memory 650. can do.

The user interface 610 receives an input signal from an input device, which may be at least one of a touch pad, a mouse, a keyboard, a joystick, a pointing stick, and a trackball.

The controller 620 detects at least one external device that can communicate when a predetermined signal is generated, selects a specific external device among the detected external devices, and the sharing setting unit 640 receives the received input signal. Option to share with external device. In order to set whether to share, a menu selected by the user may be separately provided. In addition, the predetermined signal may occur when sharing is set in the sharing setting unit 640.

The memory 650 may store at least one of preset IP addresses, MAC addresses, and GPS-related information in order to select a specific external device that can communicate with each other, and the controller 620 may refer to the memory 650 to determine a specific external device. You can select the device. Since the selection of the specific external device using at least one of an IP address, a MAC address, and a GPS is the same as described above, a detailed description thereof will be omitted.

In addition, when the received input signal is a signal corresponding to a predetermined condition, the controller 620 may control the external device interface 630 to transmit the input signal to the specific external device. The signal corresponding to the preset condition may be a signal generated in a predetermined area on the screen or a signal having a predetermined key value.

That is, when a specific button is pressed on the keyboard or a virtual button displayed on the screen, an input signal can be transmitted to a specific external device, and an input device corresponding to a pointing device such as a mouse generates a signal in a specific area on the screen. This allows the input signal to be sent to a specific external device. In this case, the specific area may be set by the user through an application installed in the terminal device.

7 is a diagram illustrating an embodiment of a condition for transmitting an input signal in a terminal device sharing an input device according to the present invention. As illustrated in FIG. 7, when the input device corresponding to the pointing device generates a signal in the areas 710 and 720 by setting the areas 710 and 720 on the screen of the terminal device 700, the preset conditions may be set. Therefore, the input signal is transmitted to a specific external device. The pointer corresponding to the pointing device may also transmit a signal or display information to the specific external device so that the pointer may be displayed on the specific external device.

8 is a diagram illustrating an embodiment in which a plurality of terminal devices share an input device according to the present invention, in which there are a plurality of external devices sharing the input device.

As illustrated in FIG. 8, an external device that transmits an input signal for each region may be divided into regions. That is, when an input signal occurs in the first area 810a, the input signal is transmitted to the first external device 810, and the terminal device 800 shares the input device with the first external device 810. On the other hand, when an input signal occurs in the second area 820a, the input signal is transmitted to the second external device 820, and the terminal device 800 shares the input device with the second external device 820.

As described above, when a plurality of terminal devices share an input device, the sharing setting unit 640 may set a list of external devices to share the input device. The list may always be set in a separate group for the external devices used together, GPS-related information about the location used by each group, the IP address of the AP may be set together and stored in the memory 650.

In addition, the controller 620 may select a specific external device according to a predetermined criterion including whether the same device is included in the same group among the external devices existing on the list. Alternatively, the external device selected through the user interface 610 may be selected as a specific external device with respect to the external device existing on the list.

As such, if a list of external devices to share the input device is set and a separate group is managed for the external devices used together, the efficiency of reducing the time for searching and accessing the external device to be shared can be increased. There is an advantage.

9 is a flowchart illustrating a data transmission protocol between terminal devices sharing an input device according to another embodiment of the present invention. Referring to FIG. 9, data for sharing an input device between a first terminal and a second terminal is described. Another embodiment of the transport protocol will be described.

When the first terminal sets the input signal received from the input device to be shared with the external device (S900), the external device that can communicate is detected (S910). The method for detecting a communicable external device may search for an external device using at least one of an IP address, a MAC address, and a GPS, and determine whether communication is possible based on the presence or absence of a communicable signal and the strength of the signal.

A specific external device, that is, a second terminal, is selected from the communicable external devices (S920), and a connection request signal is transmitted (S930). When receiving the input signal from the input device (S940) to determine whether or not to share the received input signal (S930), whether to set to share, the specific button for selecting the share is pressed, the mouse pointer in a specific area for sharing It can be determined whether or not to share through such a method.

If the determination result is to be shared, the received input signal is transmitted to the second terminal (S960). The second terminal converts a control signal capable of recognizing the received input signal (S970) and controls the second terminal accordingly.

FIG. 10 is a flowchart illustrating a method of controlling a terminal device sharing an input device according to an embodiment of the present invention. Referring to FIG. 10, a method of controlling a terminal device sharing an input device will be described.

Whether the input signal received from the input device is shared with the external device is set (S1000). When the input signal received from the input device is set to be shared with the external device, a setting signal is generated, and at least one external device that can communicate is detected according to the generation of the signal (S1010). In operation S1020, a specific external device is selected from the detected external devices.

The input device may be at least one of a touch pad, a mouse, a keyboard, a joystick, a pointing stick, and a trackball, and the selecting of the specific external device may be performed by using at least one of an IP address, a MAC address, and a GPS. Can be selected.

When receiving an input signal from the input device (S1030), it is determined whether the input signal corresponds to a predetermined condition (S1040). The signal corresponding to the preset condition is a signal generated in a predetermined area on the screen or a signal having a predetermined key value. When the input signal is a signal corresponding to a preset condition, the input signal S is transmitted to the specific external device (S1050).

FIG. 11 is a flowchart illustrating a control method of a terminal device sharing an input device according to another exemplary embodiment. Referring to FIG. 11, another control method of the terminal device sharing an input device will be described. If the control method described with reference to FIG. 10 is an embodiment of a control method of a terminal device for transmitting an input signal received from an input device to an external device, the control method described with reference to FIG. 11 is a control method of an external device receiving an input signal. One embodiment for.

In operation S1100, a terminal device capable of communicating is selected using at least one of an IP address, a MAC address, and a GPS. In this way, by allowing the user to communicate with a specific terminal device by using an IP address, MAC address, and GPS, the input device can be automatically shared between the terminal devices in a place where the user repeatedly stays long, such as a home or a company. It is convenient because there is no need for operation.

The access request signal is transmitted to the selected terminal device (S1110), and an input signal of an input device connected to the selected terminal device is received from the selected terminal device (S1120). When the received input signal is difficult to recognize, it is converted into a control signal that can be recognized, and at this time, a matching table or a specific API (Application Program Interface) function for the conversion may be used.

The API refers to an interface made to control functions provided by an operating system or a programming language for use in an application program. Accordingly, the API may be converted into a command signal that can be controlled by the terminal device in response to the input signal. Accordingly, there is an advantage in that a terminal device which cannot directly use the input device can be conveniently controlled using an input device such as a mouse or a keyboard.

For example, smartphones can't be controlled using a mouse at this time, but a mouse can be used. That is, a mouse event occurs as an input signal when the input device is a mouse. The mouse event occurs when a mouse moves, a mouse button is clicked, or a mouse wheel moves. A terminal device such as a computer that can use a mouse may perform a program or a specific operation in response to the mouse event. .

But. Such a mouse event is not recognized by the smart phone, there is a problem that can not perform a corresponding operation in the smart phone by sending a mouse event to share the mouse. Therefore, the smartphone converts the mouse event into a touch event recognizable by the smartphone in order to perform a program or a specific operation using the received mouse event. The method of mapping the movement coordinates of a mouse to the touch screen coordinates, etc. can be used. Accordingly, the user can control the smart phone using the mouse. The mouse event is equally applicable to a joystick, a pointing stick, a trackball, and the like.

In addition, when the input device is a keyboard, a keyboard event occurs as an input signal. The keyboard event occurs when a specific keyboard of the keyboard is pressed, and the external device may perform a program or a specific operation in response to the keyboard event. Therefore, when the keyboard event occurs, the input signal may be shared through a method of matching with a key value corresponding to the virtual keyboard of the smart phone.

Furthermore, although the drawings are shown for convenience of explanation, it is also possible to design a new embodiment to be implemented by merging the embodiments described in each drawing. It is also within the scope of the present invention to design a computer-readable recording medium in which a program for executing the previously described embodiments is recorded according to the needs of those skilled in the art.

A system, a terminal device, and a control method for sharing an input device according to the present invention are not limited to the configuration and method of the embodiments described above, but the embodiments may be modified in various ways. All or some of the embodiments may be selectively combined.

On the other hand, the method for controlling the terminal device sharing the input device of the present invention can be implemented as a processor-readable code on a processor-readable recording medium provided in the network device. The processor-readable recording medium includes all kinds of recording apparatuses in which data that can be read by the processor is stored. Examples of the recording medium that can be read by the processor include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may also be implemented in the form of a carrier wave such as transmission over the Internet . The processor-readable recording medium can also be distributed over network coupled computer systems so that the processor-readable code is stored and executed in a distributed fashion.
