  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  In FIG. 1, reference numeral 1 denotes a remote commander (remote operation device) as a whole, and a video tape recorder (VTR: Video Tape Recorder) (not shown), which is an operation target, is operated according to a user operation. The remote commander 1 has a display panel 2 with a touch panel function as input means for inputting operation information. As shown in FIG. 2, the display panel 2 displays various icons 3. Specifically, an on / off icon 3A for instructing on / off operation of the power supply of the VTR, and video on the video tape. A recording icon 3B for instructing recording, a stop icon 3C for instructing to stop the operation of the VTR, a rewind icon 3D for instructing rewinding of the video tape, a playback icon 3E for instructing playback of the video tape, and an instruction for fast-forwarding of the video tape The fast forward icon 3F to be displayed is displayed.

  In this state, when the user selects and touches a desired icon 3 among the plurality of icons 3A to 3F displayed on the display panel 2, the display panel 2 functions according to the selected icon 3. The selection signal S1 is sent to the control unit 5. The control unit 5 controls the entire remote commander 1, and sends a function selection signal S 1 supplied from the display panel 2 to an IR (Infrared Radiation) transmission unit 6. The IR transmitter 6 generates an infrared signal IR1 corresponding to the function selection signal S1, and transmits it to a VTR (not shown). The VTR receives the infrared signal IR1 and performs an operation according to the light reception result.

  Here, FIG. 3 shows a state transition diagram in which a desired icon 3 is sequentially selected from the plurality of icons 3A to 3F by a user operation. The user first selects the on / off icon 3A of the remote commander 1 and turns on the power of the VTR. In this state, the user may select the on / off icon 3A, the play icon 3E, the fast forward icon 3F, the rewind icon 3D, and the record icon 3B among the plurality of icons 3A to 3F. There is no possibility of selecting the stop icon 3C. This is because there is no possibility of selecting the stop icon 3C in this state because the VTR is not operating just by turning on the power of the VTR.

  For example, when the playback icon 3E is selected, the VTR transitions to the next state. In this state, the user may select the on / off icon 3A, the stop icon 3C, the fast forward icon 3F, and the rewind icon 3D among the plurality of icons 3A to 3F, whereas the playback icon 3E, There is no possibility of selecting the record icon 3B.

  As described above, the remote commander 1 can limit the range of the next selected icon 3 in a state where the desired icon 3 is selected from the plurality of icons 3A to 3F. FIG. 4 shows such a selection range of the icon 3, and represents a range of the icon 3 that may be selected this time from the previously selected icon 3.

  Specifically, if the user previously selected the on / off icon 3A, this time, the user can select the on / off icon 3A, the play icon 3E, the record icon 3B, the fast forward icon 3F, and the rewind icon 3D. However, there is no possibility of selecting the stop icon 3C. If the user previously selected the stop icon 3C, the user may select the on / off icon 3A, the play icon 3E, the record icon 3B, the fast forward icon 3F, and the rewind icon 3D this time. Thus, there is no possibility of selecting the stop icon 3C.

  Similarly, if the user selects the previous play icon 3E, this time, the user may select the on / off icon 3A, the stop icon 3C, the fast forward icon 3F, and the rewind icon 3D. If 3B is selected, the stop icon 3C may be selected this time.

  If the user selects the fast forward icon 3F last time, the user may select the on / off icon 3A, the stop icon 3C, the play icon 3E, and the rewind icon 3D this time. If selected, there is a possibility that the on / off icon 3A, the stop icon 3C, the play icon 3E, and the fast-forward icon 3F are selected this time.

  The state transition data indicating the selection range of the icon 3 is stored in the state transition storage unit 7 in advance, and is read from the state transition storage unit 7 as necessary.

  By the way, the control unit 5 is configured to send the function selection signal S1 supplied from the display panel 2 to the IR transmission unit 6 and to the frequency storage unit 9 via the assignment change unit 8. In this manner, the frequency storage unit 9 determines whether the combination of the icon 3 selected last time and the icon 3 selected this time is based on the function selection signal S1 sequentially supplied every time the user selects the desired icon 3. A frequency distribution indicating how many times it has been performed (hereinafter referred to as a function frequency distribution) is created and stored, and this function frequency distribution is updated each time the function selection signal S1 is supplied.

  Accordingly, when the user performs an operation of selecting the icon 3 a predetermined number of times or more after the start of use, the frequency storage unit 9 generates a function frequency distribution as shown in FIG. In the case of this user, for example, the last stop icon 3C is selected, and the reproduction icon 3E is next selected four times. Further, it is understood that the user selects the stop icon 3C and stops the VTR (not shown) before selecting the on / off icon 3A to turn off the power, and this user selects the icon 3. The characteristics of the selection order can be grasped.

  By the way, as shown in FIG. 6, the display screen of the display panel 2 is divided into six in the arrow X direction in the figure, and is divided into four in the arrow Y direction, for a total of 24 divisions. As shown in FIG. 7, the frequency storage unit 9 determines which position and how many times on the display screen of the display panel 2 based on the function selection signal S1 sequentially supplied every time the user selects the desired icon 3. A frequency distribution (hereinafter referred to as a position frequency distribution) indicating whether or not the touch has been made is generated. This user knows that the position indicated by the XY coordinates (5, 4) has been touched 8 times so far, indicating that the user is highly likely to select the icon 3 arranged at the position where the XY coordinates are large. ing.

  The allocation changing unit 8 reads the function frequency distribution and the position frequency distribution from the frequency storage unit 9, and determines the areas and positions of the icons 3A to 3F to be displayed based on the function frequency distribution and the position frequency distribution, respectively. An allocation change signal S2 is generated and given to the control unit 5. The control unit 5 displays each icon 3A to 3F on the display panel 2 according to the area and position based on the allocation change signal S2.

  Here, for example, determination of the areas of the icons 3A to 3F performed when the previous on / off icon 3A is selected will be described. In this case, as shown in FIG. 5, the icon 3 that may be selected next is any of an on / off icon 3A, a reproduction icon 3E, a recording icon 3B, a fast-forward icon 3F, and a rewind icon 3D. The number of times selected so far is “1, 1, 0, 0, 4”, respectively.

The allocation changing unit 8 assigns priorities F1 to F4 in the order of the number of times selected so far, that is, the rewind icon 3D, the on / off icon 3A, the play icon 3E, the record icon 3B, and the fast forward icon 3F, respectively. At the same time, the frequencies f _{1 to} f ₅ are set to “4, _{1, 1,} 0, 0”.

Therefore, the allocation changing unit 8 determines the probability p _i of the next selection of the rewind icon 3D, the on / off icon 3A, the play icon 3E, the record icon 3B, and the fast-forward icon 3F by the following equation.

Ask for. Here, Cn is the number of icons that can be selected (in this case, 5). Wc is a coefficient for weighting the probability obtained from the number of selectable icons Cn and the probability obtained from the function frequency distribution (in this case, 0.5). When this weighting coefficient Wc is increased, the coefficient is obtained from the function frequency distribution. While the influence of the probability of being selected increases, the influence of the probability obtained from the number of selectable icons Cn increases. Incidentally, when the weighting coefficient Wc is set to 1, the icon 3 that has not been selected so far is deleted from candidates that can be selected next.

Then, the allocation changing unit 8 determines the allocation area S _i allocated to each of the rewind icon 3D, the on / off icon 3A, the playback icon 3E, the recording icon 3B, and the fast-forward icon 3F by the following formula.

Ask for. Here, S _all indicates the total area that can be allocated to the icon 3. Incidentally, since the icon 3 does not necessarily need to be allocated to the entire display screen, a part (for example, 15) of the area 24 of the entire display screen is set as the total area _Sall .

  Next, determination of the positions of the icons 3A to 3F will be described. As shown in FIG. 7, it can be seen that the most easily touched position for the user is in the vicinity of (5, 4) and (6, 4) in the XY coordinates. Thereby, the allocation changing unit 8 sets the rewind icon 3D having the highest priority F1 to a position where the XY coordinates are near (5, 3), (5, 4), (6, 3), (6, 4). Decide to allocate.

  After this, the allocation changing unit 8 also has the XY coordinates (3, 2), (3, 3), (4, 2) Assign to a position near (4, 3). At this time, if the assigned on / off icon 3A overlaps the already-assigned rewind icon 3D, the assignment changing unit 8 selects the on / off icon 3A from among the positions not yet assigned. The position where the on / off icon 3A is allocated is corrected by determining the position where the button is to be allocated or changing the area to be smaller.

  In the same manner, the allocation changing unit 8 sequentially determines the positions to allocate the remaining reproduction icon 3E, recording icon 3B, and fast-forward icon 3F in order from the highest priority F. In this way, the assignment changing unit 8 sequentially determines the area and position of the icon 3 to be displayed in accordance with the function frequency distribution and the position frequency distribution stored in the frequency storage unit 9, thereby making the configuration shown in FIG. A display panel 2 having a screen as shown is generated. Thereby, it can be seen that the rewind icon 3D most likely to be selected next is displayed in the widest area and at the position where it is most easily touched.

  Here, the procedure for changing the assignment of the icon 3 by the assignment changing unit 8 will be described with reference to the flowchart shown in FIG. First, in step SP2 entered from step SP1, the allocation changing unit 8 reads the previously selected icon 3 from the frequency storage unit 9. In step SP3, the allocation changing unit 8 reads state transition data indicating the selection range of the icon 3 from the state transition storage unit 7, and extracts a candidate of the icon 3 that can be selected next from the state transition data.

  In step SP4, the assignment changing unit 8 determines whether or not the user has performed an operation of selecting the icon 3 a predetermined number of times or more after the start of use, and as a result, performs an operation of selecting the icon 3 or more of the predetermined number of times. If YES in step SP5, the process proceeds to step SP5. If the predetermined number of times has not been performed, the process proceeds to step SP6 and the process ends.

  In step SP5, the allocation changing unit 8 gives priority F to the icon 3 that may be selected next based on the function frequency distribution stored in the frequency storage unit 9. In step SP7, the allocation changing unit 8 sequentially selects the icons 3 having the highest priority from the candidates for the icon 3 that may be selected next.

  In step SP9, the assignment changing unit 8 determines whether or not the candidate for icon 3 remains, and as a result, if there remains a candidate for icon 3, the process proceeds to step SP9. The process proceeds to SP6 and the process is terminated. In step SP8, the allocation changing unit 8 determines the area and position of the selected icon 3, and after the determination, moves to step SP7.

  Next, a determination procedure (step SP9) for determining the area and position of the icon 3 will be described with reference to the flowchart shown in FIG. In step SP11 entered from step SP10, the allocation changing unit 8 determines an area for displaying the icon 3 on the display panel 2 based on the function frequency distribution. In step SP12, the allocation changing unit 8 determines a position for displaying the icon 3 on the display panel 2 based on the position frequency distribution.

  In step SP13, the assignment changing unit 8 determines whether or not the icon 3 overlaps the already assigned icon 3. As a result, if they overlap, the process proceeds to step SP14, and if they do not overlap, the process proceeds to step SP15. In step SP14, the allocation changing unit 8 corrects the allocation position of the icon 3, and then returns to step SP13 again to repeat the operation. In step SP15, the allocation changing unit 8 displays the icon 3 according to the determined area and position.

  In this state, when the user selects a desired one of the icons 3 displayed on the display panel 2, the assignment changing unit 8 adds 1 to the frequency of the selected icon 3 in step SP16, and the function frequency distribution. In step SP17, 1 is added to the frequency of the coordinates of the touched position to update the position frequency distribution. Next, the process proceeds to step SP18 and the process is terminated.

  In the above configuration, when a desired icon 3 is selected by the user, the remote commander 1 is easy to touch and large for the user in order from the icon 3 that is most likely to be selected among the icons 3 that can be selected next. By sequentially allocating and displaying on the display panel 3 in terms of area, it is possible to display icons 3 that are likely to be selected next in a state that is easy for the user to select.

  According to the above configuration, by changing the assignment of each icon 3 to the display panel 2 according to the icon 3 selected by the user, each icon 3 displayed on the display panel 2 can be easily operated by the user. Therefore, it is possible to further improve usability as compared with the conventional case.

  In this state, when the user selects a channel a predetermined number of times (for example, 100 times), the TV remote commander, as shown in FIG. 12, shows a frequency distribution (hereinafter referred to as a channel) indicating which channel is selected how many times. Called frequency distribution). In this case, the number of times that the 1-channel icon 21A, the 3-channel icon 21B, the 4-channel icon 21C, the 6-channel icon 21D, the 8-channel icon 21E, the 10-channel icon 21F, and the 12-channel icon 21G are selected is “10, 4 , 14, 15, 28, 18, 11 ".

  The TV remote commander assigns priorities in descending order of the number of times selected so far, and determines the area and position of each icon 21 in the order of the priorities. That is, the remote commander of the TV receiver assigns a large area to each icon 21 in order from the icon 21 with the highest priority, and the position touched by the user in the area where the icon 21 is displayed as shown in FIG. The shift vector indicating how much the icon 21 is shifted from the center P1 is determined, and the center of the icon 21 is moved to the position P2 indicated by the shift vector, thereby correcting the position of the entire icon 21. ing.

In step SP32, the TV remote commander determines the position of the icon 21 from the calculated deviation vector.

  In step SP33, the TV remote commander determines whether or not the icon 21 whose area and position have been determined overlaps with the already assigned icon 21. As a result, in step SP34, when it overlaps with the already assigned icon 21, the process proceeds to step SP35, and when it does not overlap, the process proceeds to step SP36 and the process is terminated. In step SP35, the TV remote commander corrects the area and position of the icon 21, and then proceeds to step SP33 to repeat the above-described operation.
