Since the right button 22 is a button in the forward direction of the user, “front” is displayed at a position corresponding to the right button 22 of the operation unit image 60, and the left button 26 is a button in the backward direction of the user. Therefore, “back” is displayed at a position corresponding to the left button 26 of the operation unit image 60. Further, a mode display unit 59 for displaying the current mode set by the mode setting unit 48 is displayed above the guide display unit 58.

  The guide 62a has “line selection (upper)”, the guide 62b has “line selection (lower)”, the guide 62c has “mode change (to character string editing mode)”, and the guide 62d has “line determination”. The guide 62e displays “Kanji conversion mode” and the guide 62f displays “delete one character”. Further, “long press: end” is displayed below the “line determination” display as a display indicating that the character input process can be ended by the long press operation of the right button 22 below the guide 62d.

  The character input selection unit 54 displays character options in the character input mode. For example, as shown in FIG. 6, when performing kana input in Japanese input, the representative character “Akasata Hamahara” is displayed in the left column 64 of the character input selection unit 54, and the selected line is displayed. A cursor 68 is displayed on the representative character. In the right column 66 of the character input selection unit 54, characters included in the line selected in the left column 64 are displayed.

  The input character display unit 56 displays a character string input by the user. In addition, the display in the input character display part 56 of FIG. 6 is an example, and it changes according to the input and deletion of a character. The character input unit 56 displays a cursor 70 indicating the position of the character to be input or deleted.

  Next, when an operation input using the operation unit 16 is performed by the user (step S4), the operation determination unit 38 determines which operation member included in the operation unit 16 is operated (step S4). S5).

  When the user rotates the wheel 18 in the vertical direction, the display control unit 42 moves the cursor 68 according to the direction in which the operation is performed as shown in the guides 62a and 62b in FIG. It performs (step S6). In FIG. 6, only “Akasana Hamaya” is shown as the representative character of the line. However, the user scrolls the left column 64 according to the rotation operation of the wheel 18, and the representative character of the line that is not displayed is displayed. Display. When scrolling is performed, the process returns to step S4.

  If it is determined in step S5 that the user has pressed down the upper button 20, the mode setting unit 48 sets the character string editing mode as shown in the guide 62c in FIG. 6 (step S7), and display control is performed. The unit 42 displays the character string editing screen (screen B) shown in FIG. 7 as the character input screen 52 (step S8).

  Here, as shown in FIG. 7, the character string editing screen (screen B) includes an input character display unit 56 and a guide display unit 58. A cursor 70 indicating a place to input a character is displayed on the input character display unit 56, and when the wheel 18 is rotated by the user, the position of the cursor 70 moves left and right.

  The guide display unit 58 displays guides 62a to 62c and 62f. In the character string editing screen (screen B) shown in FIG. 7, “to the cursor right” as the guide 62a, “to the cursor left” as the guide 62b, “character string editing mode” as the guide 62c, and “delete one character” as the guide 62f. Is displayed.

  Next, a character string editing process described later is performed (step S9). When the character string editing process is completed, the display control unit 42 displays a line selection screen (screen A) as the character input screen 52 (step S10), and step S4. Return to the process shown in.

  If it is determined in step S5 that the user has pressed the down button 24, the mode setting unit 48 sets the kanji conversion mode as shown in the guide 62e in FIG. 6 (step S11), and the display control unit 42 displays the kanji conversion screen (screen C) shown in FIG. 8 as the character input screen 52 (step S12).

  Here, as shown in FIG. 8, the Kanji conversion screen (screen C) includes an input character display unit 56, a guide display unit 58, and a conversion candidate display unit 72. The guide display unit 58 displays guides 62a, 62b, 62d, and 62f. On the Kanji conversion screen (screen C), “candidate selection (upper)” is displayed as the guide 62a, “candidate selection (lower)” as the guide 62b, “candidate determination” as the guide 62d, and “cancel” as the guide 62f. Further, the conversion candidate display unit 72 displays a cursor 73 indicating the selected conversion candidate. It should be noted that a function for changing the length of a phrase to be subjected to kanji conversion may be assigned to the upper button 20 or the lower button 24 to which no function is assigned.

  Next, kanji conversion processing described later is performed (step S13). When the kanji conversion processing is completed, a line selection screen (screen A) is displayed (step S14), and the processing returns to step S4.

  If it is determined in step S5 that the user has pressed down the right button 22, the line selected by the cursor 68 in the left column 64 of the character input selection unit 54 as shown in the guide 62d of FIG. The display control unit 42 displays the character selection screen (screen D) as the character input screen 52 as shown in FIG. 9 (step S16). Note that the character selection screen (screen D) displays a cursor 74 to be displayed on the character selected in the right column 66 of the row selection screen (screen A) shown in FIG. 6 and sets the display of the guide 62d to “Kana decision”. , The display of the guide 62f is changed to “return to row selection”.

  Next, when an operation input using the operation unit 16 is performed by the user (step S17), the operation determination unit 38 determines which operation member included in the operation unit 16 is operated (step S17). S18).

  When the user rotates the wheel 18 in the vertical direction, the display control unit 42 moves the cursor 74 according to the direction in which the operation is performed as shown in the guides 62a and 62b in FIG. Perform (step S19), and return to the process shown in step S4.

  If the user presses the left button 26 in step S18, the user moves up one level as shown in the guide 62f in FIG. 9 and returns to the line selection mode in the character input mode (step S20). ). At this time, the line selection screen (screen A) shown in FIG. 6 is displayed on the character input screen 52 (step S21), and the process returns to step S4.

  When the user presses the right button 22 in step S18, the character selected in the right column 66 is determined as shown in the guide 62d in FIG. 9, and the character is input ( Step S22). In the input character display unit 56, the input character is added, the cursor 70 is moved to the input position of the next character, and the line selection mode in the character input mode is set. Accordingly, the line selection screen (screen A) shown in FIG. 6 is displayed on the character input screen 52 (step S23), and the processing returns to step S4.

  If the user presses the upper button 20 in step S18, the process proceeds to step S7. If the user presses down the lower button 24 in step S18, the process proceeds to step S11.

  In step S4 and step S18, when the user performs a long press operation of the right button 22 such as one second or longer, the character input process is terminated.

  Next, the character string editing process shown in step S9 of FIG. 5 will be described with reference to the flowchart shown in FIG. When the mode setting unit 48 sets the character string editing mode and the character input editing screen (screen B) is displayed on the character input screen 52, an operation input using the operation unit 16 is performed by the user (step S31). S31), the operation determination unit 38 determines which operation member included in the operation unit 16 has been operated (step S32).

  When the user rotates the wheel 18 in the vertical direction, the display control unit 42 moves the cursor 70 to the left or right according to the operation direction of the user as shown by the guides 62a and 62b in FIG. Then, a position for inputting or deleting characters is selected (step S33).

  If the left button 26 is pressed by the user, one character displayed immediately before the cursor 70 is deleted as shown in the guide 62f in FIG. 7 (step S34). For example, in the case of display as in the input character display unit 56 of FIG. 7, “heaven” is deleted. A configuration may be adopted in which one character displayed immediately after the cursor 70 is deleted. In this case, it is determined whether or not a character exists immediately after the cursor 70 between step S32 and step S34, and the process shown in step S34 is performed only when the character exists. If there is no character immediately after the cursor 70, the process returns to step S31. At this time, since the pressing operation of the left button 26 is invalid, it may be displayed that the guide 62f is invalid even if an operation such as gray display or non-display of the guide 62f is performed.

  If the user presses the upper button 20 in step S32, the mode setting unit 48 sets the character input mode as shown in the guide 62c in FIG. 7 (step S35), and the character string. Exit edit mode.

  Next, the kanji conversion process shown in step S13 of FIG. 5 will be described with reference to the flowchart shown in FIG. When the mode setting unit 48 sets the kanji conversion mode and the user inputs an operation using the operation unit 16 in a state where the kanji conversion screen (screen C) is displayed as the character input screen 52 (step S51), The operation determination unit 38 determines which operation member included in the operation unit 16 has been operated (step S52).

  When the user rotates the wheel 18 in the vertical direction, the display control unit 42 moves the cursor 73 according to the operation direction of the user as shown in the guides 62a and 62b in FIG. Conversion candidates are selected (step S53).

  When the user presses the right button 22, the conversion candidate selected in the conversion candidate display unit 72 is determined as shown in the guide 62d in FIG. 8, and conversion into kanji is performed. (Step S54). Next, it is determined whether or not there is an unconverted character in the characters displayed on the input character display unit 56 (step S55). If there is an unconverted character, the conversion candidate for the next phrase is displayed on the conversion candidate display unit 72 (step S56), and the process returns to step S51. On the other hand, if there is no unconverted character, the mode setting unit 48 sets the character input mode (step S57) and ends the kanji conversion process.

  If the user presses the left button 26 in step S52, the mode setting unit 48 sets the character input mode as shown in the guide 62f in FIG. 8 (step S57), and the kanji conversion process is performed. Exit.

  According to the HMD according to the present embodiment, even when the user cannot visually recognize the operation member when the user wears it on the head, an efficient information input operation that does not burden the user. It can be performed.

  The function assigned to one operation member provided in the operation unit has a common meaning in any of the character input mode, the character string editing mode, and the kanji conversion mode. For example, the line determination function and the kana determination function are assigned to the right button 22 in the character input mode, and the function to determine the selected kanji candidate is assigned in the kanji conversion mode. That is, a determination function is assigned to the right button 22. Further, the left button 24 has a function of deleting one character in the line selection mode of the character input mode, a function of returning to line selection in the character selection mode of the character input mode, a function of deleting one character in the character string editing mode, and a kanji conversion mode. Is assigned a cancel function. That is, the left button 24 is assigned a function having a meaning of canceling an operation such as deletion or return. The upper button 20 is assigned a mode change function in the character input mode and the character string editing mode. Therefore, even when another mode is set by the mode setting unit, confusion in the user's operation can be prevented.

  In the above-described embodiment, the description has been given of the configuration in which “front” is displayed at the position corresponding to the right button 22 of the operation unit image 60 and “back” is displayed at the position corresponding to the left button 26. As shown in FIG. 15B, “rear” may be displayed at a position corresponding to the right button 22, and “front” may be displayed at a position corresponding to the left button 26. For example, the video information is input to the right eye of the user shown in FIGS. 12A and 12B from the configuration in which the display arm 10 is rotated 180 ° and the video information is input to the left eye of the user 28 shown in FIG. When switching to the configuration to be performed, the display control unit 42 switches the character input screen 52 to the display illustrated in FIG. Further, when the LR switch 15 is operated, the character input screen 52 may be switched to the display shown in FIG.

  When the HMD 2 includes an operation history storage unit that stores a user's operation history, display control may be performed using the stored operation history. For example, as shown in FIG. 13A, the character input process can be ended by the user pressing the right button 22 in the character string input mode, and the characters shown in FIGS. In the case where the character input process can be ended by the long press operation of the right button 22 as in the input mode, the frequency of the character input process end operation by the user being performed by the long press operation of the right button 22 is high. In that case, referring to the operation history stored in the operation history storage unit, the display control unit 42 may hide the guide 62d as shown in FIG.

  In addition, functions that are less frequently used may be highlighted using the operation history. For example, when the use frequency of the character input end process by the long press operation of the right button 22 is low, the display control unit 42 displays “long press: end” in the guide 62d of the guide display unit 58 as shown in FIG. Is displayed larger than the guide 62d shown in FIGS. Further, when the user does not perform an operation for a certain period of time or longer, the display control unit 42 actively uses a detailed guide 63 that displays a function that is less frequently used as shown in FIG. 14B. You may guide.

  Moreover, it is good also as a structure which can press down the upper button 20, the right button 22, the lower button 24, and the left button 26 in steps. In this case, the operation determination unit 38 distinguishes between the pressing operation and the touch to the button according to the amount of pressing of each operation button by the user. When it is determined that the button is touched, the display control unit 42 performs highlighting of the guide that displays the function assigned to the touched button. For example, when the user touches the left button 26 as shown in FIG. 15A, the guide 62f in the display of the guide display unit 58 is emphasized as compared with the guide 62f shown in FIGS. To display. By highlighting the function assigned to the touched button, an erroneous operation by the user can be prevented.

  In the above-described embodiment, when the character input field is included in the video information provided to the user and the user selects the character input field, the character input screen 52 shown in FIG. However, it may be configured to display the character input screen 52 including only the input character display unit 56 when the character input field is selected. In this case, when the operation determination unit 38 detects that the user has performed an operation using the operation unit 16, the display control unit 42 displays a character input screen 52 shown in FIG. The character input screen 52 shown in FIG. 16 displays the input character display unit 56 larger and the guide display unit 58 smaller than the character input screen 52 shown in FIGS. 6 and 9. In addition, when the character input screen 52 shown in FIG. 16 is displayed and no operation is performed by the user for a certain period of time or when a predetermined operation using the operation unit 16 is performed by the user, the display control unit 42 It switches to the character input screen 52 which consists only of the input character display part 56. FIG. In FIG. 16, “determine” is displayed as the guide 62d as an example, but the guides 62a to 62f may be hidden, or only a part of the selected guides 62a to 62f is displayed. It is good.

  In addition, the upper button 20, the right button 22, the lower button 24, and the left button 26 can be pressed stepwise, and the operation determination unit 38 determines whether the operation button is pressed or not according to the amount of pressing of each operation button by the user. When it is possible to distinguish the touch from the touch, the character input screen 52 shown in FIG. 16 may be displayed when the operation determination unit 38 detects the touch. In this case, among the guides 62a to 62f, the function assigned to the operation member whose contact is detected by the operation determination unit 38 is displayed.

  Further, when a character input field is selected, the display control unit 42 may be configured to display a character input screen 52 shown in FIG. In this case, the character input shown in FIGS. 6 and 9 in which the input character display unit 56 is displayed in one line when the user touches the operation unit 16 or performs an operation using the operation unit 16. The screen may be switched to the screen 52, or the character input screen 52 shown in FIG. When the screen is switched to the character input screen 52 shown in FIGS. 6 and 9, when there is no operation by the user for a certain period of time or when a predetermined operation using the operation unit 16 is performed by the user, FIGS. 9 is switched to the character input screen 52 shown in FIG.

  In addition, when the user is familiar with the character input operation of the HMD 2 and guide display is unnecessary, the character input screen 52 including only the input character display unit 56 is always displayed when the character input field is selected. It is good also as a setting to display.

  Further, when the guide is not displayed or only a part of the guide is displayed, the character input screen 52 is displayed by reducing the area necessary for displaying the input character display unit 56 and displaying the character input screen 52 in one line. It is good also as a structure displayed on only a part of video information provided in the. For example, when inputting characters during WEB browsing, the character input screen 52 is displayed as part of the display during WEB browsing instead of displaying the character input screen 52 on the entire surface of the video information provided to the user. can do.

  In the above-described embodiment, the operation related to character input has been described. However, guide display may be performed in the operation related to moving image reproduction. It is possible to improve the operability for an operation that requires a complicated procedure in the operation related to moving image reproduction.

For example, in AB repeat playback in which repeat playback is performed between two designated points A and B in a video file, AB repeat setting for setting the A point and B point and AB for canceling the AB repeat setting are performed. An AB repeat change operation for canceling the repeat and changing the points A and B once set can be performed, and each operation requires the following operation procedure.
(AB repeat setting)
Menu display → AB repeat setting → Search for A point → Determine A point → Search for B point → Set B point → Determine B point → End setting (AB repeat cancel)
Menu display → AB repeat cancellation (AB repeat change)
Menu display → AB repeat change → A point change / no change selection → If “Yes”, A point is searched and decided → B point change / no selection → If “Yes”, B point is found and decided → End

  Next, guide display relating to moving image reproduction will be described with reference to the drawings. For example, as shown in FIG. 17, when the user presses down the lower button 24 during moving image reproduction, the display control unit 42 displays the operation unit image 60 and the guides 62 d to 62 f on the moving image reproduction screen 76. The upper button 20, the right button 22, the lower button 24, and the left button 26 can be pressed stepwise, and the operation determination unit 38 determines whether the operation button is pressed or not according to the amount of pressing of each operation button by the user. When it is possible to distinguish the contact from the operation, the operation determination unit 38 may highlight and display the function assigned to the operation member that detected the contact. For example, as shown in FIG. 17, when the user detects contact with the lower button 24, the user 62 can be prevented from erroneous operation by highlighting the guide 62e in black.

  Next, when the user presses the down button 24, the display control unit 42 displays a menu screen 78 as shown in FIG.
