Description

  The present invention relates to an information terminal device, and more particularly to an improvement in an information terminal device that moves a focus within a menu screen in which a large number of objects are arranged in a matrix and selects one of the objects.

  In recent years, a mobile phone including an optical pointing device that can move a pointer in a display screen by sliding a finger in a detection area has been proposed (for example, Patent Document 1). In the mobile phone described in Patent Document 1, an optical pointing device is arranged in the determination key, and the movement of the finger is detected using the surface of the determination key as a detection area. An optical pointing device consists of a light projecting unit that emits detection light toward the finger and a light receiving unit that receives the detection light reflected by the finger, for example, comparing finger images generated at regular intervals By doing so, the movement amount of the finger is detected. Such an optical pointing device has high detection accuracy and can detect even a slight movement of a finger, so that it can be arranged even in a narrow space.

  For example, there may be a case where an optical pointing device is used to move the focus in a menu screen for selecting pictograms. In this case, the user slides his / her finger vertically or horizontally within the detection area. At that time, if the amount of movement of the focus corresponding to the maximum value of the amount of movement that can be input by one slide operation is made larger than the size of the menu screen, the focus is moved from one end in the menu screen by a slight movement of the finger. It can be moved to the other end. However, when the amount of movement of the focus is increased, there is a problem that when the slide operation is performed in order to select an object arranged near the end portion in the menu screen, the focus passes past the object.

  For example, when the menu screen is scrolled by moving the focus in the column direction in a menu screen in which a large number of objects are arranged in a matrix, the menu screen is unintentionally scrolled due to excessive focus. There was a problem. In particular, when all the objects in the menu screen are set as one page and the scroll of the menu screen is performed in units of this page, when the slide operation is performed to select an object in the menu screen, it is not intended due to excessive focus. A page change will occur. At this time, since all objects in the menu screen are switched by page switching, there is a problem that the relation between pages before and after switching cannot be recognized and it is not possible to know how to operate.

  In addition, when the wraparound is performed to move the focus from one end to the other end in the menu screen by moving the focus in the row direction in the menu screen, the focus is moved too far to the other end. There was a problem that the sneaking of the focus would occur. If a focus wraparound occurs when trying to select an object placed at the end, the focus will move to the opposite end. At this time, since the focus moves in the direction opposite to the direction in which the object at the end is moved, there is a problem that it is difficult to know how to operate. Therefore, it is conceivable to suppress the unintended scrolling of the menu screen by making the focus movement amount corresponding to the maximum value of the movement amount that can be input by one slide operation smaller than the size of the menu screen. However, when the focus is moved from one end of the menu screen to the other end, the slide operation has to be repeated, and there is a problem that the operability is lowered.

In addition, when moving the cursor by rotating the trackball or scrolling the screen, a technique for detecting the rotation speed of the trackball and changing the movement amount of the cursor has been proposed (for example, patents). Reference 2). The portable terminal device described in Patent Document 2 detects the rotational movement of the trackball when the trackball is rotated by sliding a finger, and moves the cursor according to the rotational movement amount. This does not solve the above-described problem that the menu screen is scrolled when a slide operation is performed to select an object arranged near the end of the menu screen.

The detection light emitted from the light projecting unit 21 is reflected by the finger on the key top 10 b, and the reflected light enters the image sensor 23 via the condenser lens 22. Based on the detection signal output from the image sensor 23, the movement of the finger is detected.

  FIG. 6 is a block diagram illustrating a configuration example of the mobile phone 1 in FIG. 1, and illustrates an example of a functional configuration in the mobile phone 1. This mobile phone 1 includes a slide operation input unit 41, a slide operation determination unit 42, a key operation detection unit 43, and a display control unit 44 in addition to the display 101, operation keys 201, and the optical sensor unit 31.

  The key operation detection unit 43 generates a key operation signal based on the pressing operation of the operation key 201 in order to generate a predetermined key event when the operation key 201 is operated, and the slide operation determination unit 42 and the display control The operation of outputting to the unit 44 is performed. That is, the key operation detection unit 43 serves as a key operation input unit that detects a key operation by the user and outputs a key operation signal indicating the moving direction of the focus.

  For example, by operating the direction key 203, the focus in the menu screen 114 can be moved in the horizontal direction or the vertical direction. In this case, the focus can be moved by one symbol from the currently selected symbol 121 to the symbol 121 adjacent to this symbol by a single key operation. In addition, the focus can be continuously moved in the same direction by long pressing the direction key 203, but the moving speed at the time of continuous movement by the long press is fixed.

  The slide operation input unit 41 performs an operation of generating a slide operation signal based on the detection signal from the optical sensor unit 31 and outputting the slide operation signal to the slide operation determination unit 42.

  The slide operation input unit 41 performs an operation of detecting a moving body based on a detection signal from the optical sensor unit 31 and outputting a slide operation signal indicating the moving amount and moving direction to the slide operation determining unit 42. The movement of the moving body is detected, for example, by comparing images composed of a two-dimensional distribution of the amount of received light between frames, and for example, the amount of movement when a finger or a touch pen is slid on the key top 10b is detected. . The detection of the movement amount is repeatedly performed at a predetermined cycle. For example, the detection value of the movement amount is output at a time interval of about 30 ms.

  The slide operation determination unit 42 performs an operation of determining a series of slide operation signals based on the slide operation signal from the slide operation input unit 41 and outputting the series of slide operation signals to the display control unit 44. A series of slide operation signals is classified by a non-operation period during which a slide operation signal is not output over a certain time.

  Specifically, the amount of movement detected by the slide operation input unit 41 or its accumulated value is compared with a predetermined threshold value Th1, and the start time of one slide operation is detected based on the comparison result. That is, when the movement amount or the accumulated value thereof exceeds the threshold Th1, the start time of one slide operation is detected, and output of a series of slide operation signals is started. After the start of the output of a series of slide operation signals, the input mode is set to the finger slide operation, and the slide operation signal is output every time the movement amount is detected until the end of one slide operation is detected.

  On the other hand, the end of one slide operation is detected when the movement of a moving body such as a finger is not detected for a certain period, and the output of a series of slide operation signals is ended. For example, when the detection value of the movement amount does not exceed the threshold value Th2 after the detection value of the movement amount falls below a predetermined threshold value Th2 until a predetermined time elapses, the end of one slide operation is detected. The Alternatively, it is detected that the movement amount exceeding the threshold value Th2 has not been detected a predetermined number of times since the detection value of the movement amount has fallen below the threshold value Th2.

  The end of one slide operation is also detected by detecting the operation of the operation key 201, and the output of a series of slide operation signals is ended based on the key operation signal from the key operation detection unit 43. There is also a case.

  The display control unit 44 controls the display 101 based on the key operation signal from the key operation detection unit 43 and the slide operation signal from the slide operation determination unit 42, and displays the menu screen 114 including the focus on the display 101. The operation to perform is performed. The display control unit 44 includes a focus movement unit 51, a scroll control unit 52, and a menu screen generation unit 53.

  The menu screen generation unit 53 performs an operation of generating a menu screen 114 in which a large number of objects are arranged in a matrix and outputting the generated menu screen 114 to the display 101. In this menu screen 114, a symbol 121 representing a pictograph is arranged as a selectable object, and the focus position is indicated by highlighting 122 the currently selected symbol 121. That is, the focus is pointer information for designating the currently selected object. Accordingly, the focus includes a mouse pointer, a cursor, and the like in addition to those represented by the reverse display 122. In the menu screen generation unit, a menu screen including such pointer information is generated.

  The object constituting the menu screen may be an icon represented by a character string or a figure in addition to symbols representing pictographs and kanji.

  The focus moving unit 51 controls the menu screen generating unit 53 based on the key operation signal from the key operation detecting unit 43 and the slide operation signal from the slide operation input unit 41, and moves the focus in the menu screen 114. Is going.

  When the direction key 203 is operated to move the focus, an operation of moving the focus by a predetermined movement amount in the movement direction indicated by the key operation signal is performed. At this time, a process of moving the focus based on the focus position at the time of key operation is performed. Specifically, if the focus is not on the peripheral edge in the menu screen 114 when the key is operated, a process of moving the focus according to one of the up / down / left / right pressed parts is performed. In addition, even when the focus is on the peripheral edge in the menu screen 114, that is, in the first row, last row, frontmost column, or last column in the menu screen 114, the key screen is moved in the menu screen 114. If it is a simple key operation, a process of moving the focus according to the pressed part of the key operation is performed.

  On the other hand, if the focus is on the peripheral edge in the menu screen 114 during key operation and the key operation is an operation that moves the focus outward from the peripheral edge, A process of moving the focus from one end to the other end facing the other end is performed. In the focus wraparound process, a line feed is performed to move the focus to an adjacent line. In other words, the focus moving unit 51 wraps around from the one end in the menu screen 114 to the other opposite end based on whether or not the focus exists in the peripheral portion in the menu screen 114 during key operation. An operation to move the focus is performed.

  When the focus is moved by a finger slide operation, a process of moving the focus is performed based on the focus position at the start of output of a series of slide operation signals. Specifically, if the focus is not at the peripheral edge in the menu screen 114 when the output of a series of slide operation signals is started, a process of moving the focus according to the detection value of the movement amount is performed. In addition, even when the focus is on the peripheral edge in the menu screen 114 at the start of output of a series of slide operation signals, if the slide operation signal is an operation signal that moves the focus within the menu screen 114, A process of moving the focus according to the detected value of the movement amount is performed.

  On the other hand, when the focus is present at the peripheral edge in the menu screen 114 at the start of output of a series of slide operation signals, and the slide operation signal is an operation signal that moves the focus outward from the peripheral edge. Then, a process is performed in which the focus is moved from one end in the menu screen 114 to the other opposite end. In the focus wraparound process, a line feed is performed to move the focus to an adjacent line. In other words, the focus moving unit 51 determines whether the other of the menu screen 114 is opposed to the other end based on whether or not the focus exists on the peripheral edge in the menu screen 114 at the start of output of a series of slide operation signals. An operation of moving the focus around the edge is performed.

  For example, when the focus is in the foremost column in the menu screen 114, if the finger is slid leftward, the focus can be moved to the last column of the previous row. Further, when the focus is in the last column in the menu screen 114, the focus can be moved to the foremost column in the next row by sliding the finger to the right.

  When the focus reaches the end of the menu screen 114 during the output of a series of slide operation signals, the focus moving unit 51 performs an operation of stopping the focus at the end and ending the focus moving process. .

  For example, when the focus reaches the last column from another column during the rightward slide operation, an operation of stopping the focus at the last column is performed.

  The scroll control unit 52 controls the menu screen generation unit 53 based on the key operation signal from the key operation detection unit 43 and the slide operation signal from the slide operation determination unit 42 to perform the operation of scrolling the menu screen 114. .

  When the menu screen 114 is scrolled by operating the direction key 203, a process of scrolling is performed based on the focus position at the time of the key operation. Specifically, the menu screen 114 can be scrolled by performing an upward or downward key operation when the focus is on the first line or the last line in the menu screen 114 during a key operation.

  When the menu screen 114 is scrolled by a finger slide operation, a process of scrolling is performed based on the focus position at the start of output of a series of slide operation signals. Specifically, when the output of a series of slide operation signals is started, the focus is on the first line or the last line in the menu screen 114, and the slide operation signal moves the focus outward from the peripheral edge. In the case of an operation signal, processing for scrolling the menu screen 114 is performed.

  For example, when the focus is on the first line in the menu screen 114, if the finger is slid upward, the menu screen 114 can be switched to the previous page and displayed. When the focus is on the last line in the menu screen 114, if the finger is slid downward, the menu screen 114 can be switched to the next page and displayed.

  Alternatively, when the focus is on the frontmost column in the first row in the menu screen 114, the menu screen 114 can be switched to the previous page and displayed even if the finger is slid leftward. Further, when the focus is on the last column in the last row in the menu screen 114, the menu screen 114 can be switched to the next page and displayed even if the finger is slid to the right.

  On the other hand, if the focus is on a line other than the first line and the last line in the menu screen 114 at the start of outputting a series of slide operation signals, the menu screen 114 is not scrolled. Further, an operation signal that causes the slide operation signal to move the focus within the menu screen 114 even when the focus is on the first line or the last line within the menu screen 114 at the start of outputting a series of slide operation signals. In this case, the menu screen 114 is not scrolled.

  That is, in the scroll control unit 52, the menu screen 114 is scrolled based on whether or not the focus exists on the peripheral portion in the menu screen 114 at the start of outputting a series of slide operation signals.

  Steps S101 to S111 in FIG. 12 are flowcharts illustrating an example of an operation when a slide operation is detected in the mobile phone 1 in FIG. First, the display control unit 44 refers to the current focus position with the start of output of a series of slide operation signals, and determines whether or not the focus is in an end row or column in the menu screen 114. (Steps S101 and S102).

  When the focus is on the end row or column, the display control unit 44 determines whether the slide operation signal input from the slide operation determination unit 42 is an operation signal that moves the focus outward from the peripheral portion. (Step S103), if the operation signal is directed outward, it is further determined whether or not the focus is on the first line or the last line in the menu screen 114 (step S104).

  At this time, if the focus is on the first line or the last line, the scroll control unit 52 scrolls the menu screen 114 to the previous page or the next page (step S105). On the other hand, the focus moving unit 51 turns the focus from one end to the opposite end when the focus is not in the first row or the last row in the menu screen 114 but in the front row or the last row. And move to an adjacent row (step S107).

  Next, the focus moving unit 51 moves the focus within the menu screen 114 according to the amount of finger movement (step S106).

  On the other hand, the focus moving unit 51 does not have the focus at the end in the menu screen 114, and an operation signal that causes the slide operation signal input from the slide operation input unit 41 to move the focus outward from the peripheral portion. If not, the focus is moved within the menu screen 114 in accordance with the amount of finger movement (step S108). When the focus reaches the end in the menu screen 114 (step S109), the focus is stopped at the end (step S110).

  The focus moving unit 51 repeats the processing procedure from step S108 to step S109 until the slide operation ends, and if the series of slide operation signal output ends without the focus reaching the end in the menu screen 114, this process is performed. Is finished (step S111).

  According to the present embodiment, when the focus is on a line other than the first line and the last line in the menu screen 114 at the start of output of a series of slide operation signals, the menu screen 114 is not scrolled. It is possible to prevent the menu screen 114 from scrolling when a slide operation is performed in order to select an object arranged near an end in the menu screen 114. Therefore, it is possible to improve the operability when selecting an object arranged near the end in the menu screen 114. Further, when the focus is on the first line or the last line when the output of a series of slide operation signals is started and the slide operation signal is an operation signal that moves the focus outward from the peripheral portion, the menu screen 114 is displayed. Since scrolling is performed, the menu screen 114 can be scrolled by a slide operation for moving the focus. Therefore, it is possible to improve the operability when selecting an object arranged in a line other than the line in the menu screen 114.

Embodiment 2. FIG.
In the first embodiment, an example has been described in which the focus in the menu screen 114 is moved in the column direction and the row direction by sliding a finger up, down, left, and right. In contrast, in the present embodiment, a case will be described in which the focus can be moved in an oblique direction in addition to the column direction and the row direction.

  FIG. 13 is a diagram showing an example of the operation in the information terminal device according to the second embodiment of the present invention, and shows all pages that can be switched by scrolling the menu screen 114. On the first page “Page 1”, 50 symbols 121 representing pictographs are arranged in 5 rows and 10 columns.

  The second page “page 2” is a page immediately after the first page, and 48 symbols 121 following the last column symbol in the last row of the first page are arranged in 5 rows and 10 columns. ing. In the last row of the second page, the last column and the column adjacent to the last column are blank (blank) 131.

  The focus can be moved in the column direction, the row direction, and the diagonal direction in the menu screen 114 by sliding the finger in the vertical direction, the horizontal direction, or the diagonal direction. That is, when moving the focus from a certain symbol 121 to an adjacent symbol, the focus can be moved in an oblique direction in addition to up, down, left, and right. The movement in the diagonal direction means movement to symbols arranged at the upper right, lower right, upper left or lower left.

  When moving the focus by a finger slide operation, first, if the focus is not in the row or column at the end of the menu screen 114 at the start of output of a series of slide operation signals, the focus is moved according to the detected value of the movement amount Processing is performed. Further, even when the focus is in the row or column at the end of the menu screen 114 at the start of outputting a series of slide operation signals, the slide operation may be an operation that moves the focus within the menu screen 114. For example, a process of moving the focus according to the detection value of the movement amount is performed.

  On the other hand, when the focus is in the row or column at the end of the menu screen 114 when the output of a series of slide operation signals is started and the slide operation is an operation that moves the focus out of the menu screen 114, the menu A process of scrolling the screen 114 in the column direction or turning the focus to the opposite side of the adjacent row is performed.

  For example, when the focus is moved from the symbol “97” in the 5th row and the 7th column on the second page by the downward sliding operation, the focus moves to the symbol “7” in the 1st row and the 7th column on the first page. To do. When the focus is moved from the symbol “97” in the 5th row and the 7th column on the second page by the slide operation in the lower left direction, the focus moves to the symbol “6” in the 1st row and the 6th column on the first page. To do.

  In addition, when the focus is moved from the symbol “40” in the 4th row and 10th column of the first page by the rightward sliding operation, the focus is moved to the symbol “41” in the 5th row and 1st column of the first page. To do. Further, when the focus is moved from the symbol “40” of the 4th row and the 10th column of the first page by the sliding operation in the lower right direction, the focus is changed to the symbol “51” of the 1st row and the 1st column of the second page. Moving.

  In addition, when the focus is moved by the slide operation in the lower left direction from the symbol “50” in the last column in the last row of the first page, the focus is the symbol in the ninth column in the first row of the second page. Move to “59”. On the other hand, when the focus is moved by a slide operation in the lower right direction, the focus moves to the symbol “61” in the second row and the first column of the second page.

  Next, consider a case where the focus is moved from the symbols “98”, “88”, “89”, and “90” adjacent to the blank 131. When the focus is moved obliquely from these symbols, the focus position after the movement is obtained by combining the movement in the column direction and the movement in the row direction. At this time, the result may be different between when the focus is moved in the column direction and then moved in the row direction and when the focus is moved in the row direction and then moved in the column direction.

  For example, when the focus is moved from the symbol “98” of 5 rows and 8 columns on the second page in the lower right direction, when the focus is first moved in the column direction and then moved in the row direction, the focus is changed to the first page. Move to the symbol “9” in the 1st row and 9th column. On the other hand, when moving first in the row direction and then in the column direction, the focus moves to the symbol “11” in the second row and the first column on the first page.

  When the focus is moved in the row direction and then moved in the column direction, the amount of movement in the column direction may be larger than when the focus is moved in the column direction and then moved in the row direction. In such a case, when moving the focus in an oblique direction, the movement in the column direction is prioritized over the movement in the row direction, and a process of moving in the row direction after moving in the column direction is performed.

  For example, if the focus is moved from the symbol “89” in the 4th row and 9th column on the second page by a downward slide operation, the focus moves to the symbol “9” in the 1st row and 9th column on the first page. To do. Also, if the focus is moved by a downward slide operation from the symbol “90” in the 4th row and 10th column of the second page, the focus moves to the symbol “10” in the 1st row and 10th column of the first page. To do. Further, when the focus is moved by a downward slide operation from the symbol “98” in the fifth row and the eighth column on the second page, the focus moves to the symbol “8” in the first row and the eighth column on the first page. To do.

  When the focus is moved from the symbol “88” in the fourth row and the eighth column on the second page by a slide operation in the lower right direction, the focus is moved by moving in the row direction after moving in the column direction. Move to the symbol “1” in the first row and the first column of the first page. In addition, when the focus is moved by a slide operation in the lower right direction from the symbol “89” in the fourth row and the ninth column on the second page, the focus is moved by moving in the row direction after moving in the column direction. Move to symbol “10” in the first row and the tenth column of the first page. Further, when the focus is moved by a slide operation in the lower right direction from the symbol “90” in the fourth row and the tenth column on the second page, the focus is moved by moving in the row direction after moving in the column direction. Move to the symbol “11” in the second row and the first column of the first page. Further, when the focus is moved by a slide operation in the lower right direction from the symbol “98” in the fifth row and the eighth column on the second page, the focus is moved by moving in the row direction after moving in the column direction. Move to the symbol “9” in the first row and the ninth column of the first page.

  When the focus is moved from the symbol “89” in the fourth row and the ninth column on the second page by a sliding operation in the lower left direction, the focus is moved to the row direction after moving in the column direction. Move to the symbol “8” in the first row and the eighth column of the page 1. In addition, when the focus is moved by a slide operation in the lower left direction from the symbol “90” in the fourth row and the tenth column on the second page, the focus is changed to the first by moving in the column direction and then moving in the row direction. Move to the symbol “9” in the 1st row and 9th column of 1 page. In addition, when the focus is moved by a slide operation in the lower left direction from the symbol “98” in the fifth row and the eighth column on the second page, the focus is moved to the row direction after moving in the column direction. Move to the symbol “7” in the first row and the seventh column of the page 1.
