JP3742018B2 - Scroll method by slide switch and mobile phone using the same - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to screen display in a mobile phone, and more particularly, to a scroll method for easily operating a display screen and a mobile phone including the same.
[0002]
[Prior art]
In mobile phones, the information displayed on the screen, such as display / registration of phone numbers and names, and display / setting of conversion candidates when creating texts, is becoming increasingly diverse and large in volume as mobile phones become more sophisticated. It is in. As a result, it is an important issue to facilitate an operation of displaying and selecting a large amount of information using a limited display screen of a mobile phone.
[0003]
In general, a method of pressing a button, a method of using a slide switch that can be moved one-dimensionally, or the like is used for screen display switching or scrolling operation.
[0004]
In the scrolling operation by pressing the button, it is necessary to press the button with a finger many times during scrolling, or it is necessary to always use it at the scrolling speed set in advance on the mobile phone. The intention of the user was not reflected.
[0005]
If the scrolling speed does not match the total amount of information displayed during scrolling and the level of difficulty in recognizing the displayed information content, the display screen may go too many times during scrolling, causing frequent scrolling. It is inconvenient to push again.
[0006]
Also, since the time from when the scroll switch is pressed to when the scrolling starts is determined by the mobile phone regardless of the user's intention, it is very inconvenient until you get used to the operation of the mobile phone you are using. become.
[0007]
A method using a slide switch or a scroll lever that can be moved one-dimensionally for switching the screen display or scrolling has been developed. For example, Japanese Patent Laid-Open No. 6-152711 (Prior Art 1) discloses a telephone provided with slide means for selecting a character displayed on a display screen by linear slider movement.
[0008]
Prior example 1 is a slide means for selecting a character by linear slider movement as a method of inputting character information when registering a destination name corresponding to a telephone number in the storage unit by information using 50-sound kana characters or English characters. Is used.
[0009]
In this case, for example, in order to select 26 English characters, 13 characters are selected by one-side operation by the forward operation of the slide means, and the remaining 13 characters are selected by the backward operation. In the case of 50-sound kana characters, the slide means is selected by reciprocating twice. According to this, it is possible to select a character and input an address by a relatively simple operation within the resolution range of the slide means.
[0010]
Japanese Patent Laying-Open No. 2000-253286 (Prior Art 2) discloses a video camera including a scroll lever that can move linearly.
Prior example 2 displays a captured image on the display screen, and scrolls the image by operating the two scroll levers in the X direction and the Y direction even when the entire image does not fit on the screen. is there.
[0011]
At this time, since the scroll lever moving range is limited, for example, when the Y-direction scroll lever reaches the upper limit, if it is necessary to further scroll the display image upward, a separate touch is provided. Operate the keys. This touch key stops the function of the scroll lever, and while the touch key is being touched, scrolling is not performed even if the X and Y direction scroll levers are moved.
[0012]
Therefore, when the movement range of the Y-direction scroll lever reaches the limit, after the Y-direction scroll lever is returned with the touch key touched, the touch state is released and the Y-direction scroll lever is moved upward. The display image can be further scrolled upward.
[0013]
In the scroll operation using the slide switch and scroll lever as in the preceding example 1 and the preceding example 2, in general, the movable range of the slide switch and the scroll lever is divided at an electrically distinguishable interval, and contacts are provided. The screen is moved by detecting the passage of the contact at a detection point on the main body side where a slide switch or a scroll lever is attached.
[0014]
Therefore, there is an advantage that it can be used at an arbitrary scrolling speed expected by the user in that the moving speed of the slide switch or scroll lever when operated by the user is directly reflected in the moving speed of the display screen.
[0015]
[Problems to be solved by the invention]
However, it is generally difficult to fit all the display candidates within the movement range of the slide switch or scroll lever so that the target display can be reliably selected while scrolling the display screen with the slide switch or scroll lever. As described above, the entire scroll is scrolled by several reciprocating operations, or the scroll lever is repeatedly operated while operating with the scroll prohibition key as in the preceding example 2, and the operation is complicated. At the same time, the operation procedure is not necessarily suitable for the user's sense.
[0016]
SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described problems in a scrolling operation of a display screen of a mobile phone and always reflect a scrolling speed desired by the user, and a mobile phone including the scrolling unit that is easy to operate.

DETAILED DESCRIPTION OF THE INVENTION
The present invention provides a scroll function of a display screen that is easy to use for a user by using a slide switch mounted on a mobile phone. Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0026]
FIG. 1 is an external view of a mobile phone provided with a slide switch according to the present invention. In FIG. 1, a slide switch 1 is mounted on one side surface of a mobile phone 3. By moving the slide switch 1 up and down as shown in the moving direction 4, the display screen displayed on the display 2 of the mobile phone 3 is scrolled.
[0027]
At this time, the mobile phone 3 not only detects the movement direction and movement amount of the vertical movement of the slide switch 1, but also detects the movement speed together to slide the scroll direction, scroll amount and scroll speed of the display screen. The movement of the switch 1 can be followed.
[0028]
By adopting the configuration and the control method as described above, the scroll amount is not fixedly determined by the mobile phone 3, and the screen 2 can be scrolled as the user desires.
[0029]
(First Embodiment) A first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 2 is a front view of the mobile phone shown in FIG. The mobile phone 3 is equipped with a slide switch 1 on its side surface. By moving the slide switch 1 by sliding it up and down along the moving direction 4, the mobile phone 3 detects the amount of movement and displays it. The display contents displayed on the device 2 are scrolled. As an example, the case where 13 lines {1: AAA} to {13: MMM} are displayed on the display 2 is shown. It should be noted that the display content is selected and confirmed when the target information is displayed at the line position surrounded by the central frame 5 among the display lines on the display screen.
[0030]
FIG. 3 is a configuration diagram of the slide switch portion showing the slide switch 1 of FIG. 2 in an enlarged manner. The slide switch 1 in FIG. 3 slides the side surface of the mobile phone 3 in the range and direction indicated by the arrow 12. A dotted line 13 is a stop position when the slide switch 1 slides in the direction of the arrow 11 and moves to the lower limit of the slide. Display information of the mobile phone 3 is displayed on the display 2.
[0031]
When the slide switch 1 moves to the slide position indicated by the dotted line 13, the slide switch 1 moves while passing through several stop positions by the holding mechanism inside the mobile phone 3. The mobile phone 3 detects where the slide switch 1 is at each stop position. Each stop position can be stopped by an internal mechanism so that it does not move even if the hand is released from the slide switch 1.
[0032]
The movement of the slide switch 1 will be described in detail with reference to FIG. FIG. 4 is a configuration diagram of the slide switch unit further expanding FIG. The slide switch unit includes a mobile phone 3 and a slide switch 1 provided in contact therewith, and a plurality of stop positions that are held when the slide switch 1 slides are provided on the mobile phone 3 side.
[0033]
In FIG. 4, corresponding to these stop positions, for convenience of explanation, numerals are attached as scales 14. The center point 16 of the slide switch 1 serves as a reference point for defining the correspondence between the slide switch 1 and the stop position indicated by the scale 14. Now, in FIG. 4, the case where the slide switch 1 exists in the 2 position of the scale 14 is shown. Here, an arrow 12 indicates a range in which the center point 16 of the slide switch 1 can move.
[0034]
The slide switch 1 can be stopped anywhere on the scale 14. Therefore, when the slide switch 1 is moved from the movable upper limit position of 1 on the scale 14 to the movable lower limit position of 9 on the scale 14 within the range of the arrow 12, there are 8 stop positions in the middle of the movement.
[0035]
That is, the slide switch 1 illustrated in FIG. 4 has nine stop positions in total including the currently stopped position. Here, for convenience, the 1 stop position of the scale 14 is referred to as a movable upper limit position, the 9 stop position of the scale 14 is referred to as a movable lower limit position, and is distinguished from a stop position in the middle from 2 of the scale 14 to 8 of the scale 14. I will do it. Therefore, hereinafter, when simply referred to as a stop position, it refers to a stop position in the middle from 2 of the scale 14 to 8 of the scale 14.
[0036]
The slide switch 1 can be pushed in the direction perpendicular to the side surface of the mobile phone 3, that is, in the direction of the arrow 19, even when the center point 16 of the slide switch 1 is at any stop position of the scale 14. . By this operation, the item displayed at the selected position of the mobile phone 3 can be determined. As shown in a frame 5 in FIG. 2, the display selection position is normally set at the center row position of the display screen.
[0037]
As long as the center point 16 of the slide switch 1 is moved between the position of the two positions and 8 of the scale 14 in FIG. 4, when moving the position of the slide switch 1 up or down by one scale, the display screen The content moves down or up one line at a time. For example, when the slide switch 1 is moved three positions upward from the position 5 on the scale 14 to the position 2 on the scale 14, the contents of the display screen also move downward by 3 lines, and the top 3 lines are newly added. Will be displayed.
[0038]
FIG. 5 is an operation diagram for explaining the scroll operation of the display screen. Assume display data arranged as data 20 in FIG. Assuming that the initially displayed screen is the display screen 21, when the slide switch 1 is lowered by one, the display screen 22 is displayed.
[0039]
When one slide switch 1 is lowered, the display screen 23 is displayed. Here, when the slide switch 1 is raised by one, the display screen 22 is restored. Thus, the display content changes in conjunction with the movement of the slide switch 1.
[0040]
On the other hand, in FIG. 4, when the slide switch 1 is moved to the movable upper limit position, i.e., the position of the scale 14, or the movable lower limit position, i.e., the position of the scale 14, the displayed data moves continuously. At this time, the data 20 continues to scroll automatically while looping.
[0041]
At this time, when the slide switch 1 is at the movable upper limit position, the display row continuously moves from the top to the bottom, and when the slide switch 1 is at the movable lower limit position, the display row is from the bottom upward. Scroll to move continuously.
[0042]
When scrolling is continuous, when the slide switch 1 is at the upper limit position of movement, that is, at the position 1 of the scale 14 in FIG. 4, the slide switch 1 is moved down to the position 2 of the scale 14 to display. Automatic scrolling can be stopped.
[0043]
Further, when the slide switch 1 is at the movable lower limit position, that is, at the 9 position on the scale 14 in FIG. 4, the automatic scrolling of the display is stopped by moving the slide switch 1 to the 8 position on the scale 14. be able to. Here, when returning to the movable upper limit position or the movable lower limit position, the screen continuously scrolls again.
[0044]
When the data to be selected by the user of the mobile phone comes to the selection position in the display 2, the desired display line can be selected and determined by pushing the slide switch 1 in the direction of the arrow 19 in FIG.
[0045]
The operation when selecting data will be described with reference to FIGS. FIG. 6 is a processing diagram showing a process of determining target data while scrolling the display screen for data having a hierarchical structure.
[0046]
In FIG. 6, data 28 is data having a hierarchical structure. For example, let us consider a case where target data {5: 1EE} in data 28 is selected. The target data {5: 1EE} is sequentially selected as one of the data of the third hierarchy in the data of the second hierarchy: {13: 5MM} in the data of the first hierarchy: {13: MMM}. Obtainable.
[0047]
It is assumed that the display screen 29 is displayed on the mobile phone 3 in the initial stage. Further, it is assumed that the position of the slide switch 1 is at the position 8 on the scale 14 in FIG. In this state, the slide switch 1 is moved up five to the position 3 on the scale 14 in FIG. As a result, the display line moves down five lines, and the screen display changes to the display screen 30 in accordance with the operation of the slide switch 1.
[0048]
On the display screen 30, the data of the first layer: {13: MMM} is displayed at the center selection position, and the slide switch 1 is pressed here to determine the selection. Simultaneously with the determination, the display screen is switched, and the data of the lower second layer included in the first layer data: {13: MMM} is displayed as the display screen 31.
[0049]
Since the target second-layer data: {13: 5MM} does not appear on the display screen 31, the slide switch 1 is moved to the 9 position on the scale 14 and automatically scrolled. Is returned to the position of 8 on the upper scale 14, and the continuous scrolling is stopped. As a result, the display screen 32 is obtained.
[0050]
On the display screen 32, the target second-layer data: {13: 5MM} is displayed in the first line, so the slide switch 1 is operated to move this line down to the selected position by two lines. Now, the slide switch 1 is at the position 8 on the scale 14 in FIG. 4. When the slide switch 1 is moved to the position 6 on the scale 14 in FIG. 4, a display screen 33 is obtained.
[0051]
If the slide switch 1 is pressed and determined, the display content is switched to the display screen 34, and the display screen of the candidate data in the lower third layer included in the second layer data: {13: 5MM} is displayed. Since the target third layer data: {5: 1EE} is displayed on the last line of the display screen 34, the slide switch 1 is operated to move this line up two lines and move it to the selected position. . Now, the slide switch 1 is at the 6 position on the scale 14, and when the slide switch 1 is moved to the 8 position on the scale 14, the display screen 35 is obtained and the target data can be reached.
[0052]
As described in the above example, whether or not the target information can be obtained by moving the scale 14 of the slide switch 1 within the movement range of 2 to 8, or the target information is included in the screen display content. The target data is reached at a high speed with a simple operation by operating a combination of the stepwise scrolling operation corresponding to the movement amount of the slide switch 1 and the continuous scrolling operation while determining whether or not It becomes possible.
[0053]
In FIG. 2, the case where the slide switch 1 is mounted on the side surface of the mobile phone 3 is shown as an example. However, the slide switch may be attached at any location on the mobile phone. FIG. 7 shows another configuration example of the mobile phone. Also in FIG. 7, the mobile phone 24 includes a display 25 and a slide switch 26, but in the configuration example of FIG. 7, the slide switch 26 is attached to the front surface of the mobile phone 24.
[0054]
(Second Embodiment) A second embodiment of the present invention will be described with reference to the drawings. FIG. 8 is an operation diagram showing a scroll operation according to the second embodiment.
[0055]
In FIG. 4, when the slide switch 1 is moved to the movable lower limit position, the mobile phone 3 detects the moving speed of the slide switch 1 from a certain position to the movable lower limit position, and scrolls the display contents at a scroll speed corresponding to the moving speed. To do.
[0056]
For example, one scale of the scale 14 in FIG. 4 is defined as one stage, the moving amount of the slide switch 1 is defined, and the moving speed of the slide switch 1 and the scroll speed of the display screen are associated in advance as shown in FIG. Keep it.
[0057]
That is, as illustrated in FIG. 8A, when the slide switch 1 reaches the movable upper limit position or the movable lower limit position at a moving speed exceeding five steps, that is, five scales per second from a certain stop position. Corresponding to this, the moving speed of the display lines on the display screen is controlled to be continuously scrolled at a scrolling speed of 8 lines per second.
[0058]
Similarly, when the slide switch 1 reaches the movable upper limit position or the movable lower limit position at a moving speed greater than 2 stages and 5 stages or less, it is continuously scrolled at a scroll speed of 5 lines per second.
[0059]
When the slide switch 1 reaches the movable upper limit position or the movable lower limit position at a movement speed of two stages or less, the scroll switch 1 is continuously scrolled at a scroll speed of two lines per second.
[0060]
In order to realize this control, when the user moves the slide switch 1, the mobile phone 3 constantly monitors the moving speed of the slide switch 1, and the slide switch 1 moves to the movable upper limit position or the movable position shown in FIG. When moved to the lower limit position, the display screen on which the data 27 is displayed is scrolled and continuously moved at the speed defined in FIG.
[0061]
In this way, the scrolling speed can be changed as desired by the user of the mobile phone, and the screen movement is easy to use. FIG. 8B illustrates the relationship between the moving speed of the slide switch 1 illustrated in FIG. 8A and the moving speed of the display screen, and the movement when the slide switch 1 moves to the movable upper limit position. This shows how the downward moving speed of the screen changes with the number of lines corresponding to the length of the arrow in FIG.
[0062]
In FIG. 4, the case where the slide switch 1 has the stop position of 9 steps has been described. However, the slide switch 1 is not particularly limited to 9 steps, and may be more or less than this. However, in order to enable the continuous scroll operation of the present invention, there are two movable upper limit positions and movable lower limit positions for executing the continuous scroll, and two for scrolling up and down stepwise according to the amount of movement of the slide switch 1. It is configured so that four or more positions in total can be identified.
[0063]
Further, in order to identify each stage, it is not always necessary to provide a stop position. For example, a variable resistor is provided in the slide switch 1 to move the slide switch 1 from the movable upper limit position to the movable lower limit position. When the resistance value of the variable resistor is continuously changed, the mobile phone 3 detects a voltage change that occurs as a result of the change in the resistance value. In this case, the movable upper limit position and the movable upper limit position of the slide switch 1 are movable. A threshold voltage corresponding to the lower limit position is defined.
[0064]
In addition, a threshold voltage is also defined that is divided by dividing the threshold voltage between the movable upper limit position and the movable lower limit position into a plurality of intermediate positions. By treating the plurality of intermediate positions discriminated based on the plurality of threshold voltages in the same manner as the plurality of stop positions, the scroll method in the case of having the stop positions can be applied as it is. However, also in this case, the mounting form is adopted in which the slide switch 1 does not move even if the hand is released from the slide switch 1.
[0065]
When the position is defined based on the threshold voltage as described above, four threshold values can be provided if a voltage change equal to or less than 1/3 of the total voltage change can be detected. For example, if the total voltage is 12V and the voltage is divided by 1/3, 0V, 4V, 8V, and 12V are obtained, and four threshold values can be provided.
[0066]
The processing may be performed with 0V corresponding to the movable lower limit position, 12V corresponding to the movable upper limit position, and 4V and 8V corresponding to a plurality of intermediate positions. The voltage detection in this case can be easily configured using a comparator. By providing four threshold values, the scroll method according to the present invention can be applied as it is as described above.
[0067]
【The invention's effect】
As described above, according to the present invention, if the slide switch is moved quickly, the display moves fast, and if the slide switch is moved slowly, scrolling of the display is also slowed. That is, the screen display can be scrolled at a desired speed according to the user's intention.
[0068]
When it is desired to automatically scroll the screen, the screen display can be continuously moved by moving the slide switch to the movable upper limit position or the movable lower limit position of the slide switch. In this case, even if data goes too much during continuous scrolling, the data can be reliably selected by moving the slide switch in stages after stopping the continuous scrolling.
[0069]
In addition to the movable upper limit position or the movable lower limit position for continuously scrolling the data on the display of the mobile phone, the screen display is continuously scrolled at a desired speed by installing a slide switch having a plurality of stop positions in the middle. It becomes possible. As a result, once the switch is touched, it is possible to select without touching the switch again until a target display item is found on the display screen.
