Description

  The present invention relates to an electronic device and a display method capable of displaying text on a touch panel, and more particularly to an electronic device and a display method for receiving a character string selection command and a screen scroll command from a user via a touch panel.

  A technique for displaying text on a display is known. A technique for receiving a command from a user by acquiring a touch position via a touch panel is also known. Specifically, the electronic device accepts selection of a software button via the touch panel, or scrolls the screen according to the slide amount by detecting a user's slide operation.

  For example, Japanese Unexamined Patent Application Publication No. 2008-204402 (Patent Document 1) discloses a user interface device. According to Japanese Patent Laying-Open No. 2008-204402 (Patent Document 1), the UI unit of a digital camera includes a display screen, and a left touch strip and a right touch strip arranged on the left outside and right outside of the display screen. . Each of the touch strips can be detected by distinguishing a sliding operation in the vertical direction and a sliding operation in the horizontal direction by the user. When a vertical slide is detected, the control unit of the UI unit accepts an operation instruction that places importance on the slide amount, such as moving the selection position of an item or scrolling the screen, and when a horizontal slide is detected. Is received as an operation instruction having a trigger meaning in which the slide amount is not important, such as a file deletion instruction or display or non-display of a new hierarchy item.

  Japanese Laid-Open Patent Publication No. 2006-129942 (Patent Document 2) discloses a program, an information storage medium, and a game device. According to Japanese Patent Laying-Open No. 2006-129942 (Patent Document 2), when performing an operation input of a pitcher's pitching operation in a baseball game, if a sliding operation is performed in the left-right direction in the touch position change area on the operation screen, the operation direction is changed. The standing position of the pitcher on the game screen changes by a distance corresponding to the operation amount in the selected direction. Then, when a slide operation from the top to the bottom is performed so as to pass through the gate on the operation screen, a pitcher pitching motion is started on the game screen. Thereafter, when the slide operation is continued to the ball type / ball speed selection area, the ball type / ball speed corresponding to the touch position is selected, and the pitching course is changed in the left / right direction according to the operation amount in the left / right direction.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated. Hereinafter, an electronic dictionary will be described as a representative example of “electronic device”. However, the “electronic device” can also be realized by another information terminal having a touch panel such as a personal computer, a mobile phone, an electronic notebook, a PDA (Personal Digital Assistant).

<Outline of operation of electronic dictionary 100>
First, an outline of the operation of electronic dictionary 100 according to the present embodiment will be described. FIG. 1 is an image diagram showing an outline of operation of electronic dictionary 100 according to the present embodiment. More specifically, FIG. 1A is an image diagram showing a state in which the electronic dictionary 100 displays text. FIG. 1B is an image diagram showing a state in which the user's finger slides in the left-right direction on the text displayed on the touch panel 120. FIG.1 (c) is an image figure which shows the state as which the text was selected. FIG. 1D is an image diagram showing a state where the user's finger slides up and down on the text displayed on the touch panel 120. FIG.1 (e) is an image figure which shows the state by which the screen was scrolled.

  With reference to Fig.1 (a), the electronic dictionary 100 displays the searched word and the explanatory note of the said word, for example. The user's finger touches the text on the touch panel 120.

  With reference to FIG.1 (b), a user's finger | toe slides in the left-right direction on the touchscreen 120 surface. For example, the user's finger slides from the letter “B” to the letter “E” in the text written on the touch panel 120.

  With reference to FIG.1 (c), the electronic dictionary 100 receives the selection command (range selection) of the character string which the user's finger | toe passed based on touch operation (slide operation). The touch panel 120 inverts the selected character string in black and white. For example, the electronic dictionary 100 can search a dictionary database based on a character string (jump function).

  On the other hand, referring to FIG. 1D, the user's finger slides on the surface of touch panel 120 in the vertical direction. For example, the user's finger slides from the letter “B” in the text written on the touch panel 120 toward the information.

  With reference to FIG.1 (e), the electronic dictionary 100 receives the scroll command of a screen based on touch operation (slide operation). For example, the display position of the text and the text range to be displayed can be changed so that the line containing the character touched by the user's finger first moves to the position where the user's finger stops (the position where the user's finger is released) change.

  Thus, the user can easily (with one touch) input a character string selection command and a screen scroll command. In other words, the user does not input a command for switching between a mode for inputting a character string selection command and a mode for inputting a screen scroll command, and the character string selection command and the screen A scroll command can be input. In addition, there is no need to display software buttons for scrolling separately from the text.

  Hereinafter, a specific configuration of the electronic dictionary 100 for realizing such a function will be described in detail.

<Hardware Configuration of Electronic Dictionary 100>
Next, an aspect of a specific configuration of the electronic dictionary 100 will be described. FIG. 2 is a block diagram showing a hardware configuration of electronic dictionary 100. Referring to FIG. 2, electronic dictionary 100 includes a CPU 110, touch panel 120, memory 130, memory interface 140, communication interface 150, and clock 160 as main components.

  The touch panel 120 may be any type such as a resistive film method, a surface acoustic wave method, an infrared method, an electromagnetic induction method, and a capacitance method. The touch panel 120 may include an optical sensor liquid crystal. The touch panel 120 detects a touch operation on the touch panel 120 by an external object every predetermined time, and inputs touch coordinates (touch position) to the CPU 110. In other words, the CPU 110 sequentially acquires touch coordinates from the touch panel 120.

  The memory 130 is realized by various types of RAM (Random Access Memory), ROM (Read-Only Memory), a hard disk, and the like. The memory 130 stores programs executed by the CPU 110, a dictionary database in which words and explanatory texts (also referred to as texts) are associated, time series data of touch coordinates input via the touch panel 120, and the like. To do. In other words, the CPU 110 controls each unit of the electronic dictionary 100 by executing a program stored in the memory 130.

  The memory interface 140 reads data from the external storage medium 141. In other words, the CPU 110 reads data stored in the external storage medium 141 via the memory interface 140 and stores the data in the memory 130. Conversely, the CPU 110 reads data from the memory 130 and stores the data in the external storage medium 141 via the memory interface 140.

  The storage medium 141 includes a CD-ROM (Compact Disc-Read Only Memory), a DVD-ROM (Digital Versatile Disk-Read Only Memory), a USB (Universal Serial Bus) memory, a memory card, an FD (Flexible Disk), Hard disk, magnetic tape, cassette tape, MO (Magnetic Optical Disc), MD (Mini Disc), IC (Integrated Circuit) card (excluding memory card), optical card, mask ROM, EPROM, EEPROM (Electronically Erasable Programmable Read-Only) A medium for storing the program in a nonvolatile manner such as Memory).

  The communication interface 150 is realized by an antenna or a connector. The communication interface 150 exchanges data with other devices by wired communication or wireless communication. In other words, the CPU 110 receives a program, image data, text data, or the like from another device via the communication interface 150, or transmits image data or text data to another device.

  The clock 160 measures time or a period based on a command from the CPU 110. Based on the time from the clock 160, the CPU 110 stores the time corresponding to the touch coordinates in the memory 130 as a time series.

  The CPU 110 controls each unit of the electronic dictionary 100 by executing a program stored in the memory 130 or the storage medium 141. That is, the CPU 110 executes the program stored in the memory 130 or the storage medium 141, thereby performing the operation illustrated in FIG. 1, the determination method illustrated in FIGS. 3 to 10, and the processes illustrated in FIGS. Is realized.

<Mode judgment method>
Below, the mode determination method performed by CPU110 is demonstrated. CPU 110 displays text on touch panel 120. In the present embodiment, when text is displayed, a display area is assigned to each character. The display area is a rectangle that encloses characters.

  The CPU 110 acquires touch coordinates (touch start position) via the touch panel 120. The CPU 110 specifies a character (start character) including the touch start position. The CPU 110 sequentially acquires touch coordinates on the touch panel 120. CPU 110 determines whether or not the current touch coordinates have reached the start character display area.

  When CPU 110 determines that the current touch coordinate has reached the start character display area, the current touch coordinate is above or below the start character display area (both are collectively referred to as a vertical area). Judge whether it is located. When the current touch coordinates are located above or below the start character display area, CPU 110 accepts a screen scroll command based on the touch coordinates. When the current touch coordinates are not located above and below the display area of the start character, CPU 110 accepts a character string selection command based on the touch coordinates.

<First determination method>
Hereinafter, the first determination method will be described in more detail. FIG. 3 is an image diagram showing a first determination method according to the present embodiment.

  Referring to FIG. 3, CPU 110 determines that the touch coordinates are outside the first rectangular area and within a predetermined angle θ1 (vertical area, dot area in FIG. 3) from the vertical direction of the touch start position. In addition, it is determined that the sliding direction is the vertical direction. In other words, the CPU 110 determines that the slide direction is the vertical direction when the touch coordinates are located outside the first rectangular area and the angle between the direction from the touch start position to the touch coordinates and the vertical direction is less than the predetermined angle θ1. It is judged that.

  When the touch coordinates are outside the first rectangular area and outside the predetermined angle θ1 (horizontal area, hatched area in FIG. 3) from the vertical direction of the touch start position, the CPU 110 determines that the slide direction is horizontal. It is judged that. In other words, the CPU 110 determines that the slide direction is the horizontal direction when the touch coordinates are located outside the first rectangular area, and the angle between the direction from the touch start position to the touch coordinates and the vertical direction is equal to or greater than the predetermined angle θ1. It is judged that.

  Alternatively, the CPU 110 determines that the slide direction is the horizontal direction when the touch coordinates are outside the first rectangular area and within the predetermined angle θ2 (horizontal area) from the horizontal direction of the touch start position. To do. In other words, the CPU 110 determines that the slide direction is the horizontal direction when the touch coordinates are located outside the first rectangular area and the angle between the direction from the touch start position to the touch coordinates and the left-right direction is less than the predetermined angle θ2. It is judged that.

  The CPU 110 determines that the slide direction is the horizontal direction when the touch coordinates are outside the first rectangular area and located outside the predetermined angle θ2 (vertical area) from the left and right direction of the touch start position. In other words, the CPU 110 determines that the slide direction is the vertical direction when the touch coordinates are located outside the first rectangular area and the angle between the direction from the touch start position to the touch coordinates and the horizontal direction is equal to or greater than the predetermined angle θ2. It is judged that.

  Note that, in common with the first determination method and the second determination process, the CPU 110 receives an angle θ1 between the vertical straight line and the first straight line from the user via the touch panel 120 or an input device such as a button. Alternatively, it is preferable to accept the setting of the angle θ2 (= 90−θ1) between the horizontal straight line and the first straight line. That is, it is easy to input a screen scroll command by increasing the angle θ1 (decreasing the angle θ2), or inputting a character string selection command by decreasing the angle θ1 (increasing the angle θ2). It can be done easily.

<Second determination method>
Hereinafter, the second determination method will be described in more detail. FIG. 4 is an image diagram showing a second determination method according to the present embodiment.

  Referring to FIG. 4, CPU 110 assumes that the first straight line from the upper right end of the first rectangular area toward the upper right direction is the boundary line between the right direction and the upper direction of the slide. The CPU 110 assumes that the second straight line extending from the upper left end of the first rectangular area toward the upper left direction is a boundary line between the left direction and the upper direction of the slide. The CPU 110 assumes a third straight line extending from the lower right end of the first rectangular area to the lower right direction as a boundary line between the right direction and the lower direction of the slide. CPU110 assumes that the 4th straight line which goes to a lower left direction from the lower left end of a 1st rectangular area is a boundary line of the left direction of a slide, and a downward direction.

  When the touch coordinates are located above the first rectangular area and between the first straight line and the second straight line (vertical area, dot area in FIG. 4), the CPU 110 determines that the slide direction is Judged to be in the vertical direction. When the touch coordinates are located below the first rectangular area and between the third straight line and the fourth straight line (vertical area, dot area in FIG. 4), the CPU 110 determines that the slide direction is Judged to be in the vertical direction.

  The CPU 110 determines the slide direction when the touch coordinates are located to the right of the first rectangular area and between the first straight line and the third straight line (lateral area, hatched area in FIG. 4). Is determined to be in the horizontal direction. The CPU 110 determines the slide direction when the touch coordinates are located to the left of the first rectangular area and between the second straight line and the fourth straight line (lateral area, hatched area in FIG. 4). Is determined to be in the horizontal direction.

<Third determination method>
Hereinafter, the third determination method will be described in more detail. FIG. 5 is an image diagram showing a third determination method according to the present embodiment.

  Referring to FIG. 5, CPU 110 is located outside the first rectangular area and outside the line including the character including the touch start position (vertical area, dot area in FIG. 5). In this case, it is determined that the slide direction is the vertical direction. The CPU 110 determines that the slide direction is horizontal when the touch coordinates are outside the first rectangular area and inside the line including the character including the touch start position (horizontal area, hatched area in FIG. 5). Judge that the direction.

  In other words, in the third determination method, the angle θ1 between the vertical line and the first line in FIG. 4 is set to 90 degrees, or the angle between the horizontal line and the first line. This corresponds to the case where θ2 (= 90−θ1) is set to 0 degree.

<Fourth determination method>
Hereinafter, the fourth determination method will be described in more detail. FIG. 6 is an image diagram showing a fourth determination method according to the present embodiment.

  Referring to FIG. 6, CPU 110 is located outside the first rectangular area and inside the row including the character including the touch start position (vertical area, dot area in FIG. 6). In this case, it is determined that the slide direction is the vertical direction. The CPU 110 determines that the slide direction is horizontal when the touch coordinates are outside the first rectangular area and outside the column including the character including the touch start position (horizontal area, hatched area in FIG. 6). Judge that the direction.

  In other words, in the fourth determination method, the angle θ1 between the vertical straight line and the first straight line in FIG. 6 is set to 0 degrees, or the angle between the horizontal straight line and the first straight line. This corresponds to the case where θ2 (= 90−θ1) is set to 90 degrees.

<Fifth determination method>
Hereinafter, the fifth determination method will be described in more detail. FIG. 7 is an image diagram showing a fifth determination method according to the present embodiment.

  Referring to FIG. 7, CPU 110 determines that the current touch coordinates are outside the first rectangular area and the second rectangle having the same size as the first rectangular area with the touch start position as the center in the vertical direction. It is determined whether or not the area has been reached. When determining that the CPU 110 is outside the first rectangular area and has reached the outside of the second rectangular area, the CPU 110 determines the slide direction based on the first to fourth determination methods.

  CPU110 performs a scroll process, when the first touch coordinates are not on a text (when it is NO in step S108) (step S200). The scroll process will be described later. When the scroll process ends, CPU 110 repeats the process from step S102.

  If the first touch coordinates are on the text (YES in step S108), CPU 110 stores information in memory 130 of information to identify the character (start character) that includes the first touch coordinates. CPU 110 causes the character touched on touch panel 120 to be displayed in black and white reversed (step S110).

  CPU 110 determines whether or not the current touch coordinates are on the start character (step S112). CPU110 repeats the process from step S112, when the present touch coordinate is on a start character (when it is YES in step S112).

  CPU110 performs a mode determination process, when the present touch coordinate is not on a start character (when it is NO in step S112) (step S300). The mode determination process will be described later.
