Description

  The present invention relates to a remote control system and a remote control method including an image display device such as a television and a remote controller that performs remote control of the image display device.

  An image display device (for example, a television) is provided with a remote controller (hereinafter referred to as “remote controller”) so that the image display device can be controlled by remote operation. The number of buttons (one button for one operation) necessary for controlling the image display device is arranged on the surface of the conventional remote control. Press the button to operate the image display device.

  In recent years, as image display devices have become more multifunctional, such as digital reception and recording functions, there is an increasing need to provide a remote controller with many control functions, that is, to arrange many buttons. However, increasing the number of buttons in a limited area of the remote control decreases the size of the buttons or narrows the distance between the buttons, thus reducing operability.

  There is also a method of reducing the number of buttons by providing several control functions for one button and changing the function according to the scene. However, even with this method, operability is reduced.

  In order to solve the above problem, for example, Patent Document 1 proposes a method of providing an LCD (liquid crystal display) and a touch panel as a remote controller. In this technique, the user remotely operates the image display device by touching an icon or option displayed on the touch panel. And by switching icons and choices displayed according to the scene, many control functions can be assigned to a limited area, and the user can easily operate.

JP 9-305305 A

  However, when a large amount of information is displayed on the LCD provided in the remote controller, the display performance required for the LCD inevitably increases. Further, when displaying information at that time, functions to be added to the remote control such as a function of receiving information from the image display device (that is, a bidirectional function) are increased. Therefore, the cost becomes high. In addition, since the power consumption increases, it is not suitable to adopt an LCD for a remote controller driven by a battery.

  In view of the above-described problems, the present invention provides a remote control system and a remote control method that reduce the cost and power consumption of a remote controller, assign many control functions, and improve operability.

  In order to achieve the above object, in a remote control system having an image display device and a remote controller for performing remote control of the image display device, the remote controller is transparent and has a first display area; and A transmission unit configured to transmit coordinate information indicating the x-coordinate and y-coordinate of the point touched on the touch panel to the image display device, and the image display device includes a second display region for displaying an operation screen; An execution unit that executes a function corresponding to the coordinate information, wherein the x and y coordinates of the first display area and the x and y coordinates of the second display area correspond to the remote control system. provide.

  With the remote control system and the remote control method of the present application, it is possible to reduce the cost and power consumption of the remote controller, assign many control functions, and improve operability.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In addition, the same number is attached | subjected to the process which performs the structure part which has the same function, and the same process, and duplication description is abbreviate | omitted.

  The remote control system 1000 according to the present embodiment includes a remote controller (hereinafter referred to as “remote controller”) 100 and an image display device 200. The image display device 200 is remotely controlled by the remote controller 100. The image display device 200 is, for example, a television. In the following description, the image display device is described as being a television.

  FIG. 1 is a simplified perspective view of the image display apparatus 200. The image display device 200 includes a display unit 258. The display unit 258 displays an image (for example, a television image). An operation screen 320 for the remote control 100 is displayed in the second display area 202 which is a partial area in the display unit 258. The operation screen 320 is a collection of operation keys 310. In the example of FIG. 1, it is assumed that the operation screen 320 includes 12 operation keys. A function is associated with each operation key. The function indicates a function for changing the channel of the image display apparatus 200, a function for adjusting the volume, and the like. If the image display device 200 is an integrated television and video, the functions include a fast-forward function and a pause function.

  FIG. 2 is a perspective view of the remote controller 100 according to the first embodiment. In this example, the remote control 100 has a touch panel 102. The touch panel 102 is transparent to such an extent that the user can visually recognize the back side of the remote controller 100.

  FIG. 3 is a diagram illustrating the remote control system 1000 according to the first embodiment, that is, a perspective view illustrating that the user A remotely controls the image display apparatus 200 using the remote controller 100. As shown in FIG. 3, the user A points the transparent touch panel 102 toward the operation screen 320 displayed in the second display area 202 (facing the person directly). Then, since the touch panel 102 is transparent, a similar shape of the operation screen 320 is displayed on the touch panel 102. An area in the touch panel 102 where the operation screen 320 is displayed is a first display area 104, and an operation screen displayed in the first display area 104 is an operation screen 320 '. The user A can visually recognize the operation screen 320 through the touch panel 102. In other words, the touch panel 102 functions as a transparent window, and the user A puts the operation screen 320 on the touch panel 102 (transparent window) for visual recognition. Further, the transparency means that the user A can be transparent or semi-transparent to such an extent that the user A can see the operation screen 320 through the touch panel 102.

  Then, the user A touches the operation screen 320 ′ displayed in the first display area 104 with the input unit, and causes the image display device 200 to execute the function of the touched operation key. Here, the input means is a finger A1 of the user A, a stylus pen, or the like. The “touch” refers to an act of pressing the touch panel 102 (contacting the touch panel 102) with an input unit such as a finger or a stylus pen. Details of the processing will be described below.

  FIG. 4 is a schematic diagram when the remote controller 100 and the image display device 200 are viewed from the front. Here, the x coordinate and the y coordinate of the first display area 104 of the touch panel 102 correspond to the x coordinate and the y coordinate of the second display area 202 of the display unit 258. The correspondence between the x-coordinate and the y-coordinate means that the x-coordinate value and the y-coordinate value from the origin 0 of the first display area 104 and the second display area 202 are the same. In the operation screen 320 illustrated in FIG. 4, for example, the function corresponding to the operation key arranged at the uppermost position in the leftmost column is “increase the volume”.

  There are various types of touch panel 102 such as a transparent resistance film method, a capacitance method, and an electromagnetic induction method, but it is preferable to use a transparent resistance film method. This is because the transparent resistive film method is low in manufacturing cost and can be touched (coordinate input) with both the finger A1 of the user A and the stylus pen. Note that a touch panel other than the resistive film type may be used as the touch panel 102. Alternatively, a stylus pen may be attached to the remote controller 100 and the touch panel 102 may be touched with the stylus pen. Hereinafter, a transparent resistive film type touch panel will be briefly described.

  FIG. 5A is a cross-sectional view of the transparent resistive film type touch panel 102. FIG. 5B is a cross-sectional view when the touch panel 102 is touched by an input unit. As shown in FIG. 5A, the touch panel 102 includes a first electrode substrate 18, a second electrode substrate 20, a dot spacer 22, and the like. The first electrode substrate 18 and the second electrode substrate 20 face each other, and the first electrode substrate 18 is located above the second electrode substrate 20. The first electrode substrate 18 and the second electrode substrate 20 are kept at a certain distance by a spacer (not shown). The first electrode substrate 18 is formed of, for example, a film (PET: polyethylene terephthalate), and the second electrode substrate 20 is formed of, for example, glass.

  A first resistance film 11 and a second resistance film 12 are formed on the opposing surfaces of the first electrode substrate 18 and the second electrode substrate 20, respectively. The first resistance film 11 and the second resistance film 12 are, for example, ITO (indium tin oxide). Further, the dot spacers 22 are provided so as not to make erroneous contact due to the bending of the first electrode substrate 18 due to external factors such as the environment.

  Then, as shown in FIG. 5B, when the first electrode substrate 18 is touched, the first electrode substrate 18 bends and the first resistance film 11 and the second resistance film 12 come into contact with each other.

  FIG. 6 is a perspective view of the first resistance film 11 and the second resistance film 12, and a block diagram of the remote controller 100 and the image display device 200. FIG. 7 is a flowchart showing main processes of the remote controller 100 and the image display device 200. FIG. 6 shows only the first resistance film 11 and the second resistance film 12 in the touch panel 102. In the example of FIG. 6, the remote controller 100 includes a voltage application unit 152, a detection unit 154, a transmission unit 156, and a control unit 160 in addition to the touch panel 102. Further, the image display apparatus 200 includes a receiving unit 252, a function assigning unit 253, an executing unit 254, a storage unit 256, and the display unit 258 illustrated in FIG.

  In this example, the first resistance film 11 and the second resistance film are both rectangular. The first resistance film 11 and the second resistance film 12 each have an input region 13. The input area 13 is an area where coordinates are input when the user A touches. A first electrode 15 is provided on the periphery of both long sides of the first electrode substrate 18. Further, the second electrode 16 is provided on the peripheral edge on both short sides of the second electrode substrate 20. That is, the first electrode 15 and the second electrode 16 are arranged in directions orthogonal to each other.

  The voltage application unit 152 alternately applies a voltage to the first electrode 15 and the second electrode 16. As shown in FIG. 5B, when the user touches the first electrode substrate 18 with an input means such as a finger (Yes in step S2), the first electrode substrate 18 bends, whereby the first resistance film 11 and the second resistance film 12 come into contact with each other. Then, when a voltage is applied to the first electrode 15, the voltage is divided at the contact point (pressed point), so that the conversion unit 101 can detect the y coordinate of the contact point. Further, when a voltage is applied to the second electrode 16, the voltage is divided at the contact point, so that the detection unit 154 can detect the x coordinate of the contact point. In the following description, information about the x coordinate and the y coordinate is referred to as coordinate information. If the answer is No in step S2, the remote controller 100 waits until the touch panel 102 is touched.

  The detection unit 154 detects coordinate information of a point where the first conductive film 22 and the second conductive film 12 are in contact (that is, a point touched by the user A) (step S4). Then, the transmission unit 156 transmits the coordinate information detected by the detection unit 154 to the image display device 200 (step S6). As a transmission method of the transmission unit 156, conventionally used infrared light or the like may be used.

  The receiving unit 252 of the image display device 200 receives the coordinate information from the transmitting unit 156 (step S8). The storage unit 256 stores correspondence information (correspondence table) that associates coordinate information with the function of the operation key for the operation key 310 displayed in the second display area 202. FIG. 8 shows an example of correspondence information stored in the storage unit 256.

In the example of FIG. 8, for example, input coordinate information (x _{1 to} x ₂ , y _{1 to} y ₂ ) corresponds to the function “increase volume”. The function assigning unit 253 refers to the correspondence information and assigns a function corresponding to the received coordinate information of the correspondence information (step S10). Then, the function assignment unit 253 generates information about the assigned function (hereinafter referred to as function information). For example, when the received coordinate information is (x _α , y _α ), it is determined to which range of the coordinate information in the correspondence information the coordinate information (x _α , y _α ) belongs. For example, when x ₁ <x _α <x ₂ and y ₃ <y _α <y ₄ , the coordinate information (x _α , y _α ) corresponds to the “reduce volume” function. Then, the function assignment unit 253 generates function information regarding the function of “decreasing the volume”. The generated function information is transmitted to the execution unit 254.

  The execution unit 254 executes a function for the transmitted function information (step S12). For example, the execution unit 254 executes the function of “decrease the volume” when the function information regarding the function of “decrease the volume” is transmitted.

  Further, for example, when the number of operation keys 310 is small, the user A does not need to put the operation screen 320 on the touch panel 102. The reason why the user A does not need to be adjusted will be described. The user A directly recognizes the operation key 310 displayed on the image display device 200 (without passing through the touch panel 102), and has the function desired by the user A. The operation key 310 is determined. Then, the user A determines the corresponding position of the determined operation key 310 in the touch panel 102 based on an eye amount, and touches the determined corresponding position, so that the user A desires the image display apparatus 200. It is possible to execute the function.

  However, when the number of operation keys 310 is large, the operation desired by the user A may not be executed accurately unless the operation screen 320 is aligned with the touch panel 102. Therefore, in order for the user A to perform an accurate operation, as shown in FIG. 3, it is preferable that the user A performs the operation by putting the operation screen 320 on the transparent touch panel 102.

  Thus, if it is an image display apparatus including the remote controller of the first embodiment, the user A can visually recognize the operation screen 320 through the touch panel 102. Then, by touching the operation key on the visually recognized operation screen 320 ′, the function of the touched operation key can be executed by the image display device 200. Further, when the number of operation keys 310 is small, the user A can cause the image display device 200 to execute a desired function without seeing the operation screen 320 through the touch panel 102.

  The information transmitted from the remote control 100 to the image display device 200 is only the coordinate information of the point touched on the touch panel 102. Further, the image display apparatus 200 does not need to transmit any information to the remote controller 100. Accordingly, it is not necessary to perform bidirectional communication between the image display device 200 and the remote controller 100 as in the technique described in Patent Document 1.

  In addition, the remote controller 100 does not need to have an LCD, and has only a transparent touch panel 102. Therefore, the cost and power consumption of the remote controller can be reduced.

  Further, by increasing the number of operation keys on the operation screen 320 displayed on the second display area 202 of the display unit 258, many functions can be easily assigned to the remote controller 100, and operability can be improved. it can.

  FIG. 9 is a perspective view of the remote controller 400 of the second embodiment. The remote controller 400 has a first operation unit 402 at a lower position of the transparent touch panel 102 as compared with the remote controller 100 shown in FIG. In this example, the first operation unit 402 is, for example, a push switch.

  The user A performs a predetermined operation on the first operation unit 402. Here, the predetermined operation is an operation of pressing the press switch when the first operation unit 402 is a press switch. For a predetermined time t after the pressing switch 402 is pressed by the user A, the control unit 160 enables the transmission unit 156 in the touch panel 102 to transmit coordinate information. In other words, the control unit 160 does not cause the transmission unit 156 to transmit coordinate information after a predetermined time t has elapsed since the predetermined operation was performed on the first operation unit 402.

  Here, “allowing transmission of coordinate information by the transmission unit 156” means that the transmission unit 156 can transmit the coordinate information touched on the touch panel 102 to the image display device 200. On the other hand, “to make it impossible to transmit coordinate information by the transmission unit 156” means that even if the user A touches the touch panel 102, the transmission unit 156 displays the coordinate information touched on the touch panel 102 as an image display device. That is, it is not transmitted to 200.

  Further, while the pressing switch 402 is being pressed by the user A, the control unit 160 may enable transmission of coordinate information by the transmission unit 156 in the touch panel 102. In other words, unless the pressing switch 402 is pressed by the user A, the control unit 160 does not cause the transmission unit 156 to transmit coordinate information. In the following, “transmission of coordinate information by the transmission unit 156” is referred to as enabling the function of the touch panel 102, and “non-transmission of coordinate information by the transmission unit 156” is disabled. To do.

  In addition, to disable the function of the touch panel 102, the control unit 160 may stop the voltage application process of the voltage application unit 152. Further, the control unit 160 may not cause the detection unit 154 to perform coordinate detection processing. Other methods may be used. Even with these configurations, the transmission unit 156 has the same meaning as the configuration in which the coordinate information is not transmitted (the transmission of the coordinate information by the transmission unit 156 is impossible).

  In the above description, the first operation unit 402 is described as a push switch. However, the first operation unit 402 may be other means, such as a rotary switch.

  As described above, in the remote control system according to the second embodiment, even when the user A accidentally touches the touch panel 102 or when the touch panel 102 is touched due to an external factor, an erroneous function is displayed. The display device 200 is not executed.

  FIG. 9 is a perspective view of a remote controller 500 of the remote control system according to the third embodiment. The remote controller 500 has a second operation unit 404 shown in parentheses. The second operation unit 404 is operated to display the operation screen 320 on the image display device 200. In this example, the second operation unit 404 is a push switch.

  The user A performs a predetermined operation on the second operation unit 404. Here, the predetermined operation is an operation of pressing the press switch when the second operation unit 404 is a press switch. When a predetermined operation is performed on the second operation unit 404 by the user A, the control unit 160 generates an operation screen display signal, and the transmission unit 156 (see FIG. 6) displays the generated operation screen display. The signal is transmitted to the image display device 200. When the reception unit 252 receives the operation screen display signal, the execution unit 254 displays the operation screen 320 in the second display area 202 of the display unit 258.

  The displayed operation screen 320 can be erased by a predetermined operation on the second operation unit 404 (when the second operation unit 404 is a press switch, an operation of pressing the press switch). For example, the operation screen 320 may be erased when a predetermined operation is performed on the second operation unit 404 while the operation screen 320 is displayed in the second display area 202.

  As described above, since the remote controller 100 includes the second operation unit 404, the user A can display the operation screen on the image display device 200 when the user A desires the operation, or the displayed operation. The screen can be erased. Therefore, the user A can view an image such as a TV image without being obstructed by the operation screen 320.

  Further, it may be preferable to integrate the first operation unit 402 (described in the second embodiment) and the second operation unit 404. Hereinafter, the integrated first operation unit 402 and second operation unit 404 are collectively referred to as a first operation unit 402 ′. In this case, when a predetermined operation is performed on the first operation unit 402 ′, the function of the touch panel 102 may be validated and the operation screen 320 may be displayed on the image display device 200.

  If the remote control system is configured in this way, when the user A desires to execute some function (for example, increase the volume) while viewing the TV image of the image display device 200, for example, 1 The operation unit 402 is operated. Then, an operation screen is displayed on the image display device 200, and the function of the touch panel 102 is enabled. Therefore, a desired function can be executed by the remote controller 500. That is, the user A can see a TV image that is not superimposed on the operation screen, and does not cause the image display apparatus 200 to execute a wrong function due to a malfunction caused by the user A or an external factor. The user A can cause the image display apparatus 200 to execute a desired function.

  FIG. 10 is a perspective view of a remote controller 600 of the remote control system according to the fourth embodiment. The remote controller 600 has a third operation unit 601. The third operation unit 601 enlarges or reduces the operation screen based on the operation performed by the third operation unit 601.

  In the example of FIG. 10, the third operation unit 601 is a pair of push switches. The pair of push switches are a first push switch 602 and a second push switch 604. The operation performed by the third operation unit 601 is an operation of pressing the first press switch 602 and the second press switch 604. When the first press switch 602 is pressed, the control unit 160 generates an enlarged signal for enlarging the operation screen 320 and transmits the enlarged signal generated by the transmission unit 156 to the image display device 200. When the reception unit 252 of the image display device 200 receives the enlarged signal, the execution unit 254 enlarges the operation screen 320 and displays it on the second display area 202 of the display unit 258.

  On the other hand, when the second pressing switch 604 is pressed, the control unit 160 generates a reduction signal for reducing the operation screen 320 and the transmission unit 156 transmits the reduction signal generated to the image display device 200. To do. When the reception unit 252 of the image display device 200 receives the reduction signal, the execution unit 254 reduces the operation screen 320 and displays it on the second display area 202 of the display unit 258.

  Further, the degree of enlargement or reduction of the operation screen 320 is determined based on, for example, the number of times the user presses the first press switch 602 or the second press switch 604 and the duration of the press. That's fine.

  The third operation unit 601 may be a rotary switch (knob) instead of a pair of push switches. In this case, when the user A rotates the rotary switch in the clockwise direction, the control unit 160 generates an enlarged signal, and the transmission unit 156 transmits the generated enlarged signal to the image display device 200. . When the user A rotates the rotary switch counterclockwise, the control unit 160 generates a reduction signal, and the transmission unit 156 transmits the generated reduction signal to the image display device 200. The degree of enlargement or reduction of the operation screen 320 in this case may be based on the rotation angle of the rotary switch.

  Since the remote control 600 of the remote control system according to the fourth embodiment includes the third operation unit 601, the operation screen 320 displayed in the second display area 202 of the display unit 258 is enlarged or expanded by the user's remote operation. Can be reduced. Therefore, even when the screen does not fit within the frame of the touch panel 102 or when the operation screen 320 ′ displayed on the touch panel 102 is small, the user A can change the position of the remote controller 102 or the user A's There is no need to adjust the location.

  FIG. 11 is a simplified view of the remote controller 700 and the image display device 720 according to the fifth embodiment when viewed from the front. As shown in FIG. 11, the operation screen 320 displays ruled lines 722 (hereinafter referred to as “first ruled lines”) indicated by broken lines for each operation key 310. In FIG. 11, the ruled line 722 is shown by a broken line for clarity, but it may actually be a solid line or a broken line. Further, the ruled line 722 may be light in color so that the user A cannot easily see the operation key 310.

  On the other hand, the touch panel 102 displays a second ruled line 702 corresponding to both the x coordinate and the y coordinate of the first ruled line 722. In this way, the first ruled line 722 and the second ruled line 702 are formed, and the user A superimposes the first ruled line 722 and the second ruled line 702, so that the operation screen is displayed on the first display area 104 of the touch panel 102. 320 can be easily fitted and operability is improved.

  In addition, if the first ruled line 722 and the second ruled line 702 are formed, the user A does not need to fit the operation screen 320 into the first display area 104 of the touch panel 102. For example, when the user A desires the function “increase the volume” of the operation key α on the operation screen 320, the position of the operation key α is visually confirmed. In the example of FIG. 11, the operation key α corresponds to the operation key in the second row from the top of the leftmost column. The user A may touch the area α ′ in the second row from the top of the leftmost column of the first display area 104, which is the same position as the operation screen 320. Then, the transmission unit 156 transmits the coordinate information corresponding to the region α ′ to the image display device 200, and can cause the execution unit 254 of the image display device 200 to execute the function of the operation key α.

  In the example of FIG. 11, both the first ruled line 722 and the second ruled line 702 are displayed so as to surround one operation key, but both the first ruled line 722 and the second ruled line 702 are only vertical lines. Or only a horizontal line may be sufficient. Further, both the first ruled line 722 and the second ruled line 702 may be ruled lines surrounding a plurality of operation keys.

  Further, a ruled line display operation unit (not shown) may be provided in the remote controller 700, and the user A may display the first ruled line 722 and the second ruled line 702 by performing a predetermined operation on the ruled line display operation unit. The ruled line display operation unit is, for example, a push button, and the predetermined operation is to press the push button.

  With the configuration of the fifth embodiment, the user A can easily and accurately display the operation screen 320 displayed on the second display area 202 of the display unit 258 by combining the first ruled line 722 and the second ruled line 702. Can be fitted to the touch panel 102. Further, the user A can cause the execution unit 254 to execute a desired function without fitting the operation screen 320 to the touch panel 102, and the operability of the remote control is significantly improved.

  In the image display device 820 of the sixth embodiment, a plurality of operation screens are displayed in the second display area 202 of the display unit 258, and the user A can use the remote control to display a desired operation screen from among the plurality of operation screens. Let them choose. FIG. 12 shows an example in which a plurality of (four in the example of FIG. 12) operation screens 3021 to 3024 are displayed on the image display device 200. FIG. 13 is a perspective view of the remote controller 800 according to the sixth embodiment. In the example of FIG. 12, since there are four operation screens including 12 operation keys, 48 operation keys are displayed. That is, with the remote control system according to the sixth embodiment, the operation keys can be easily increased without deteriorating operability.

  Next, two methods for selecting the operation screens 3021 to 3024 will be described. First, as a first selection method, the fourth operation means 802 is provided on the remote controller 800. The fourth operation unit 802 is for selecting one operation screen from among a plurality of operation screens displayed on the image display device 200. In the example of FIG. 13, the fourth operation unit 802 is, for example, a first press switch 8021, a second press switch 8022, a third press switch 8023, and a fourth press switch 8024 that are four press switches. The four push switches 8021 to 8024 correspond to the operation screens 3021 to 3024, respectively.

  User A presses the pressing switch corresponding to the desired operation screen. For example, if the user A desires the second operation screen 3022, the user A presses the second push switch 8022 corresponding to the second operation screen 3022. Then, the control unit 160 generates a second operation screen selection signal. The generated second operation screen selection signal is transmitted to the image display device 200 by the transmission unit 156. When the image display device 200 receives the second operation screen selection signal, the second operation screen 3022 is displayed in the second display area 202 of the display unit 258. Then, the user A may perform the above-described operation on the selected second operation screen 3022.

  Further, a knob may be used as another means of the fourth operation means 802. The user A may select a desired one of the first operation screen 3021 to the fourth operation screen 3024 by rotating the knob.

As a second selection method, the user A puts a plurality of operation screens 3021 to 3024 on the touch panel 102 and touches an area on the touch panel 102 where a desired operation screen is displayed. The operation screen may be selected. In this way, it is not necessary to provide the fourth operation unit on the remote controller 100.
With the remote control system of the sixth embodiment, the number of operation keys 310 can be increased without deteriorating the operability of the remote control.

  In addition, in the touch panel 102 of the remote controller 100, a portion exposed to the outside is preferably formed of a polymer resin. This is because the remote controller 100 may fall due to the carelessness of the user A and the touch panel 102 may be damaged.
