  The information display device according to the present invention will be specifically described below with reference to FIGS. In the following description, a television receiver will be described as an example of one embodiment of the information display device, but the present invention can also be applied to a personal computer or a game. Here, FIG. 1 is a schematic diagram of a television receiver. FIG. 2 is an apparatus block diagram of the television receiver. FIG. 3 is a content search flowchart. FIG. 4 is a content search screen diagram. 5 and 8 are flowcharts of content browsing. 6, 7, 9, and 10 are arrangement diagrams of content browsing screens.

  First, the outline of the television receiver according to this embodiment will be described with reference to FIG. In FIG. 1, the television receiver according to this embodiment includes a receiver main body 100 having a display unit 101 and a remote controller 50 for inputting various operations of the receiver main body 100. The receiver main body 100 may be an integrated ultra-general television receiver in which the display unit 101, the storage unit 102 (illustrated in FIG. 2) and the like are housed in one housing, or the display unit 101 may be connected to another device. A separate display portion type housing structure may be used. Here, the description is made with an integrated television receiver.

  The remote controller 50 is a remote operation type operation instruction device that performs a selection operation (moving operation) of the focus state (selection state) displayed on the display unit 101 with the touch pad unit 51. In this embodiment, an example in which channel selection and various operations can be remotely controlled using an infrared signal will be described, but the present invention is not limited to this, and a wireless device is provided or an operation is performed via a cord. A structure for instructing a signal to the receiver main body may be used. In this embodiment, the focus state selection operation is described using the touch pad unit 51. However, the focus state selection operation may be performed by a pointing device that is attached to a remote controller or the like and is operated with a fingertip while being held by a hand. good.

  In this television receiver, contents such as television broadcasting can be viewed by a tuner 103 (shown in FIG. 2) built in the receiver main body 100, and a control unit 111 built in the receiver main body 100 is instructed from the remote controller 50. Based on the operation, a plurality of operation buttons and icons to which a specific function is assigned or a selection branch 40 such as a photographic image or a moving image is displayed on the display screen 101a of the display unit 101. A focus state is moved by a coordinate position signal composed of an X coordinate and a Y coordinate instructed by the touch pad unit 51, and this focus state is selected by aligning, and a specific function is selected for the selected selection branch 40. Is assigned, the specific function can be executed.

  One of the major features of this television receiver is that a list of a plurality of options 40 is displayed on the display screen 101a based on the operation of the remote controller 50 including the touch pad unit 51 that is a coordinate indicating device. This is because the arrangement can be changed according to the display magnification and the selection of options in the list can be selected by an instruction operation of the touch pad unit 51. That is, the touch pad unit 51 according to this embodiment employs a pressure detection unit 54 that can detect the pressure of the touch. Then, in the light touch operation shown in (a), the change of the arrangement according to the magnification of the list display is accepted. In the strong touch operation shown in (b), the focus state option 40 in the list display is changed to X. It is accepted as a movement operation in the axial direction and the Y-axis direction.

  That is, in this embodiment, the coordinate instruction signal of the touch pad unit 51 which is a coordinate indicating device is switched between the first mode and the second mode via the pressure right grain 54 which is a switching means, and the first mode In this mode, the magnification is changed on the basis of the coordinate signal in the Y-axis direction, the screen in the left-right direction is scrolled on the basis of the coordinate signal in the X-axis direction, and the number of displayed lines is increased or decreased with the change in the magnification. Correspondingly, the arrangement of the list display is changed by the number of displayed lines, and in the second mode, the option at a predetermined position of the list display set in advance is set to the focus state, and the Y axis direction and the X axis The focus state is moved based on a direction coordinate signal.

  According to this feature, it is possible to determine the target option 40 from the options displayed in the list display by changing the list display to a viewable size with a light touch operation and performing a strong touch operation as it is. . Here, when a strong touch operation is received, the option 40 displayed at a predetermined position (home position) of the list display is set to the focus state as indicated by the hatched portion, and this focus state is indicated by the instruction of the touch pad unit 51. It can be moved by operation.

  In this embodiment, an example of the touch panel unit 51 capable of detecting pressure will be described. However, a coordinate pointing device that can determine the moving direction and moving amount of a trackball, a mouse, and the like, and the moving direction and moving amount are controlled by two operations. You may make it combine with switching means, such as the operation button switched to instruction | indication.

  Another major feature of the television receiver is that a list of a plurality of options 40 is displayed on the display screen 101a based on the operation of the remote controller 50 provided with the touch pad unit 51, and the magnification of the list display is shown. The instruction is received by a light touch operation, and the arrangement of the selection branches 40 corresponding to the magnification instruction is automatically performed. That is, in this embodiment, the Y-axis direction of the touch pad unit 51 is defined as a magnification, and the movement in the X-axis direction is defined as screen scroll in the Y-axis direction.

  In general, the display screen 101a has a horizontally long shape in which the dimension in the horizontal direction (X-axis direction) is larger than that in the vertical direction (Y-axis direction). In addition, when scrolling the screen by displaying a list of a plurality of selection branches 40, the screen scroll in the horizontal direction (X-axis direction) is more suitable for the movement of the human eye than the movement in the vertical direction (Y-axis direction). You can also. Therefore, in this embodiment, the movement of the touch pad unit 51 in the Y-axis direction is accepted as a magnification, and continuous enlargement or reduction is performed according to the amount of movement in the Y-axis direction. Further, the movement in the X-axis direction is accepted as a screen scroll and is continuously moved in accordance with the movement amount in the X-axis direction.

  As described above, in this embodiment, based on the operation instruction of the touch pad unit 51, the magnification instruction of the display screen 101a is received as the Y coordinate, and the screen scroll instruction in the left and right direction (X axis direction) is received as the X coordinate. The operability can be improved.

  Another major feature of this television receiver is that the arrangement is automatically changed in accordance with the enlargement / reduction ratio. That is, in this embodiment, in principle, the selection branches 40 are arranged in a matrix of N rows and M columns. In FIG. 1, a case where the total number of selection branches 40 is 24 is described. In this example, displaying a list of 4 rows and 6 columns on one display screen 101a is a list display of the minimum magnification, and conversely, at least one selection branch 40 is displayed in the full width of the display screen 101a. Is defined as the maximum magnification. The minimum magnification and the maximum magnification may be larger or smaller, but the arrangement is not changed.

  In order to realize this arrangement, in this embodiment, the selection branches 40 are arranged in the order of columns from top to bottom and rows from left to right. Therefore, as shown in FIG. 1, the selection branches 40 are sequentially arranged from the top to the bottom of the left side row m1 and from the top to the bottom of the next left side row m2. In the array change, the definition is made so that the number N of rows increases or decreases with the magnification change, starting from the n1 row.

  Then, when the magnification is enlarged and “option 4” of n4m1 becomes invisible from the display screen 101a, that is, when the lower end of the display screen 101a enters the region of n3, the control unit 111 changes “selection branch 4” of n4m4. The position is moved to the position of n1m2, and the subsequent selection branches 40 are rearranged according to the arrow P. In the case of reduction, the reverse control is performed.

  As described above, in this embodiment, the “option 4” is arranged by rearranging the “selection branch 4” of the selection branch n4m4 that has become invisible from the display screen 101a with the enlargement. Never forget to see. These options 40 are virtually arranged on the right side of the display screen by rearrangement. These options 40 can be listed by moving them in the X-axis direction via the touch pad unit 51.

  In the example of FIG. 1, the case where “selected branch 1” is visible on the display screen 101a has been described. For example, when there are more selected branches 40 and the screen is scrolled, a predetermined line (center of the screen) is displayed. The screen is scrolled so that the selection branch 40 at the top of the screen is positioned in a predetermined line (center of the screen) that has been newly rearranged. As a result, the selection branch 40 that disappears from the display screen 101a due to the enlargement is placed on the right side of the predetermined line, thereby reducing forgetting to see.

  Hereinafter, a more detailed description will be given with reference to FIGS.

  In FIG. 2, the remote controller 50 instructs a touch pad unit 51 including a coordinate detection unit 53 that detects a touch operation, a movement direction and a movement amount, and a pressure detection unit 54 that detects a pressure applied to the touch pad, and a determination operation. A determination operation switch 56 and an operation button 57 are provided. In addition, an infrared communication unit 58 for transmitting and receiving an infrared signal from the infrared transmission window, a storage unit 59 for storing an operation program, an operation history, and the like, and a control unit 60 for comprehensively controlling the operation control of the remote controller 50. And a vibration drive unit 61 that applies vibration to the remote controller 50 receiver main body 100 based on an instruction from the control unit 60.

  On the other hand, the receiver main body 100 that operates based on an operation instruction of the remote controller 50 includes a display unit 101 for displaying a menu screen and a list for operation, an audio output unit 105 such as a speaker, and an antenna 106. , A network communication unit 108 for acquiring content from the Internet 107 via a communication line, an infrared communication unit 109 for transmitting and receiving an infrared signal from the remote controller 50, various programs, This is a very general device including a storage unit 110 that stores content and the like, and a control unit 111 that comprehensively controls each device of the receiver body 100.

  In this embodiment, bidirectional communication is performed between the infrared communication unit 58 and the infrared communication unit 109 to receive a signal from the receiver main body 100 and to the user via the vibration drive unit 61. I can inform you. However, two-way communication is necessary when the force feedback is performed, but one-way communication from the remote controller 50 to the receiver main body 100 is sufficient when the force feedback is not performed. In this embodiment, infrared communication is employed, but wireless communication using radio waves may be employed instead.

  Next, the content search operation will be described with reference to the operation flow diagram of FIG. 3 and the screen diagram of FIG. In FIG. 3, when the control unit 111 of the receiver main body 100 according to this embodiment receives an operation of a menu button that is one operation switch of the operation button 57 of the remote controller 50 (step 300), the contents shown in FIG. The search menu screen 200 is displayed on the display screen 101a (step 302).

  In this menu screen 200, a plurality of folders are arranged in a column, and a plurality of contents belonging to the folder selected in the folder area 201 are displayed on the list display screen 202. In the folder area 201, one folder is always in the focus state (selected state) 203. FIG. 4 shows a state in which the folder C is selected in the folder area 201.

  When the control unit 111 monitors the operation signal of the touch pad unit 51 and receives a movement signal of the Y coordinate (step 306), the focus state 203 indicates that the folder displayed in the column in the folder region 201 is the Y coordinate. (Step 414). When the focus state 203 is at the upper end or the lower end and further a movement instruction is received, the screen is scrolled. Then, the control unit 111 displays the contents belonging to the folder selected in the folder area 201 on the list display screen 202, and when the selection in the folder area 201 is changed, the display of the contents is switched according to this selection.

  On the other hand, when the control unit 111 receives the movement signal of the X coordinate (step 308), the control unit 111 causes the content list arranged on the list display screen 202 to be horizontally scrolled in the designated direction (step 316).

  When the control unit 111 receives an operation of the enter key from the remote controller 50 (step 310), the folder area 201 is hidden and the list display screen 210 as shown in FIG. 6 in which the list display screen 202 is enlarged is displayed. Is displayed on the list display screen 210, and the list 40 of options 40 related to the searched content is displayed, and an enlargement / reduction operation flow of the list display becomes possible (step 312).

  Next, referring to the screen transition diagrams of FIGS. 6 and 7, and FIGS. 9 and 10, the selection operation of the option 40 on the list display screen 210 and the enlargement / reduction operation based on the operation flow diagrams of FIGS. The flow will be specifically described.

  First, an operation flow of the selection operation of the option 40 will be described with reference to FIGS.

  In FIG. 5, when the control unit 111 receives an operation of the determination key from the remote controller 50 in the operation of the menu screen 200, the control unit 111 displays a list display screen 210 on which the list of options 40 related to the content in the focus state 203 is displayed. Display (step 320). As shown in FIG. 6A, the list display screen 210 includes a content display area 211. In this content display area 211, N rows and M columns of options 40 are displayed in the left column according to a preset order. They are arranged in the order from the top to the bottom, and from the top to the bottom of the next row.

  When displaying the list display screen 210, the control unit 111 monitors whether the touch operation of the touch pad unit 51 has been touched more strongly than a preset reference value (step 321). If it is lightly touched, it proceeds to step 352 shown in FIG. 8, and if it is determined that it is strongly touched, it is positioned at a preset home position (for example, the center of the screen) as shown in FIG. 6B. The selection 40a is set to the focus state 203 (step 322). Then, the control unit 111 determines whether or not the X-axis operation has been performed (step 32), the Y-axis operation (step 324), or the determination operation has been performed in this strongly touched state. Whether or not (step 325) is monitored. That is, when the touch pad 51 is strongly touched, the focus state 203 appears at the home position, and if the touch pad 51 is operated in this state, the focus state 203 is moved in the direction to be worn, and the selection 40 The function assigned to can be executed.

  Here, when the operation of the X axis is performed via the touch pad unit 51, the control unit 111 receives a movement operation in the right direction by the touch pad unit 51, for example, as illustrated in FIG. When the display of the content display area 211 is scrolled in the direction opposite to the direction indicated by the touch pad unit 51, and the option 40a in the focus state 203 is moved out of the home position, the option 40b next coming to the home position is displayed. By setting the focus state 203, as shown in FIG. 6D, the focus state 203 is moved in accordance with the rightward movement operation by the touch pad unit 51 (step 327). The operation of scrolling the screen while maintaining this home position will be described with reference to FIG.

  In FIG. 7A, in this embodiment, the home position is set at a predetermined position in the content display area 211 within a predetermined range (horizontal width). That is, a home position having a range of Q width in the center of the content display area 211 in the X-axis direction is set. When the operation instruction Q1 in the right direction is given by the touch pad unit 51, the screen in the content display area 211 is scrolled to the right side Q2 opposite to the operation instruction Q1. In this case, the option 41a in the focus state 203 moves according to the screen scroll Q2 as shown in FIG. 5B, but when the center Q3 of the option 40a exceeds the home position range as shown in FIG. Next, the option 40b to move to the home position is set to the focus state 203, which moves to the left side Q2 as shown in FIG. Then, by repeating this movement, the options 40 are successively brought into the focus state 203 in accordance with the operation instruction Q <b> 1 in the right direction by the touch pad unit 51.

  Returning to FIG. 5, however, when the arrangement of the options 40 ends, the final option 40 cannot be set to the focus state 203 in the operation for maintaining the home position. Therefore, in this embodiment, as shown in FIG. 6E, when the movement operation to the left in the X-axis direction is continued, it is monitored whether or not the screen scrolling is finished (step 328). When the screen scrolling is completed, the focus state 203 is moved in the coordinate indicating direction (left side direction) of the touch pad unit 51 (step 329). If the screen scrolling is not completed, step 329 is bypassed and step 330 is reached. In step 330, it is monitored whether or not the touch pad 51 has been touched. If the touch operation is released, the process returns to step 321. If the touch operation is not released, the process returns to step 327.

  On the other hand, in step 327, when the Y axis is operated by the touch pad unit 51, the control unit 111 follows the movement direction and moves the focus state 203 in the Y axis instruction direction (step 331), thereby performing the touch operation. Is released (step 332). If released, the process returns to step 321, and if not released, step 331 is continued.

  When the control unit 111 determines in step 325 that the determination operation has been performed, the control unit 111 performs an operation of opening the content that is a function assigned to the option 40.

  Next, an enlargement / reduction operation flow of the list display screen 210 will be specifically described with reference to FIGS. First, the characteristics of the list display screen 210 will be described with reference to FIG. Here, FIG. 9A shows an arrangement in a state of shifting from the minimum magnification to an enlarged display, and FIG. 9B shows an arrangement in a state further enlarged and reduced by one line.

In FIG. 9, when the control unit 111 receives an operation of the determination key from the remote controller 50 in the operation of the menu screen 200, the control unit 111 displays a list display screen 210 on which the list of options 40 related to the content in the focus state 203 is displayed. Display The list display screen 210 includes a content display area 211, and the content display area 211 can display the maximum display number Q1 obtained in N rows and M columns, that is, N rows × M columns. For example, in the example of FIG. 9, there are 24 content totals Q2, and the total content Q2 is displayed in a matrix of 4 rows and 6 columns (same as the maximum display number Q1). The state in which the matrix of 4 rows and 6 columns is displayed on the display screen 101a is the minimum magnification. The control unit 111 calculates the number of rows and the number of columns from the content number Q2 of the content selected in the folder area 201 and displays this list display screen 210 which is an initial screen.

  Returning to FIG. 8, the control unit 111 receives a light touch coordinate signal from the touch pad unit 51 of the remote controller 50, and if it is an X coordinate signal, the control unit 111 scrolls the screen horizontally in the indicated direction (step 352). If there is, the display screen 101a is controlled as an enlargement / reduction signal in the Y-axis direction (vertical direction) (step 354). However, when the magnification exceeds a predetermined value, that is, when the number of lines displayed on the display screen 101a changes, the content arrangement is changed (step 356).

  That is, in FIG. 6, as shown in FIG. 6A, when an enlargement instruction is given, the control unit 111 enlarges the display content according to the instruction speed. Since the relationship between the display content and the display screen 101a is a relative change, it can be considered that enlargement is the same as making the frame 101b of the display screen 101a smaller. In this embodiment, since the enlargement / reduction is set with the upper left as a base point, the control unit 111 is instructed to enlarge, and the lower end of the frame 101b is changed from the region n4 of 4 rows to the region n3 of 3 rows. When entering, that is, when the number of displayed lines is reduced by one line, (b) as shown in the figure, “content 4” is moved from the position of n4m1 to the position of n1m2, so that the matrix arrangement is displayed from 4 lines to 3 lines. Change the display to. Here, as the number of rows decreases, the number of columns increases. This can be dealt with by scrolling the screen. In reduced display, an operation opposite to the affirmative operation is performed to increase the number of rows.

  FIG. 10 shows a change in the display content of the list display screen 210 with a change in the number of rows. (A) As shown in the figure, when the number of lines changes, the position where each content is displayed changes in accordance with the change. (B) The figure has shown the arrangement | sequence of the state reduced 1 line from the state of (a) figure. Further, (c) shows an arrangement when there are two lines, and (d) shows a list display screen 210 in a state where it becomes one line. Here, (a) the state of the figure is the minimum magnification, and (d) the figure is the maximum display magnification. The enlargement / reduction ratio may be further reduced from (a) or may be further enlarged from (d), but the arrangement is not changed.

  Returning to FIG. 8, as described above, in step 356, when the lower end of the frame 101b is increased or decreased from the current row area (step 356), the selection branch (content) at the upper part of the predetermined column is stored (step 358). Here, in the example of FIG. 9, the option (content 1) at the top of the m1 column is stored. Then, based on the increase / decrease in the number of rows, the control unit 111 rearranges the table (step 360), and scrolls the screen so that the option (content) of the predetermined row becomes the predetermined row (step 362).

  Here, step 356 and step 360 may be operated without being performed, but by providing this step, the visibility of the screen can be improved. For example, by setting the predetermined row to be stored as the center of the display screen 101a, the content arranged in the uppermost part of the center is always present at the center even if the arrangement changes due to the change in the number of rows. Even if there is a lot of content in 211, the target one is always in the center, so it is possible to reduce lost children and confusion associated with the change in arrangement.

  When the arrangement is changed, the control unit 111 monitors increase / decrease in the number of rows based on the changed number of rows (step 366). Further, the control unit 111 monitors the maximum magnification and the minimum magnification. That is, when the number n of rows is 1 (step 366), the enlargement is limited with no further enlargement (step 370). On the other hand, when the number of contents to be displayed is the same as or exceeds the total number of contents (step 368), the reduction is restricted with no further reduction (step 372).

  As described above, according to the information display device such as the television receiver according to this embodiment, it is easy to see a large number of options 40 based on the operation of the coordinate pointing device such as the touch pad unit 51. A list is displayed at a magnification, and a target option is selected from the list display, and a function assigned to the option can be easily executed.
