TECHNICAL FIELD OF THE INVENTION
The present invention relates to a screen display process for information input by using operation buttons and position input means such as a touch panel in a portable information device.
[0002]
[Prior art]
2. Description of the Related Art In recent years, the size of portable information devices has been gradually decreasing due to user demands and technological advances. Accordingly, a display device for displaying information of a portable information device has also become smaller. In order to display as much information as possible on such a limited-sized display, various display processes such as parallel translation of the display screen and enlargement / reduction of the screen to display a desired image can be performed. More things to do. It is generally known that a touch panel or the like is provided on a display in order to easily perform these operations, and the position information on the screen is input using an input pen.
[0003]
If you only need to "see" information, simply drag a part of the display screen with the input pen to move the screen in parallel, or hit the area you want to enlarge with the input pen (hereinafter, tap). Some of them can be enlarged and displayed at a fixed magnification. However, as for the information screen which needs to be selected by tapping each part of the display screen with the input pen, the selection operation, the movement and the enlargement operation are overlapped, so that the above operation means cannot be taken. In such a case, the operation means described below is used.
[0004]
For example, a situation will be described in which a wide range of map data is displayed on a display, and it is desired to magnify only a certain location on the map to see details. On this screen, if you tap a place name on the screen, the screen switches and information about the place name is displayed. To enlarge only a certain part, first open the display menu screen and select "Enlarge" . As a result, the center of the display screen is enlarged at a predetermined fixed magnification. Then, by dragging a scroll bar or the like at the end of the screen with an input pen, the display screen can be moved to a desired position by operating an operation key on the portable information device, so that an enlarged screen of a desired position can be displayed. Alternatively, after selecting "enlarge", there is a case where a predetermined enlargement operation (for example, tapping an area to be enlarged with an input pen) enlarges the area at a fixed magnification. In some cases, the screen can be gradually enlarged by repeating the same operation.
[0005]
When "reducing", the display menu screen is opened in the same manner as in "enlarging", and by selecting "reducing", it is possible to return to a wide range of map data display at a fixed magnification.
[0006]
[Problems to be solved by the invention]
In the conventional method described above, it is necessary to open the menu screen every time switching between “enlarge” and “reduce”, and also to move the screen, it is necessary to accurately grab the scroll bar at the end of the screen and drag it.

[0032]
FIG. 5 is a flowchart illustrating a processing procedure when the display screen of the portable information device 301 is translated. In the portable information device 301, when an input is made on the touch panel 112, the process is started from step S501. In step S502, it is detected whether or not the move key 305 is ON. If not, the process proceeds to a screen enlargement / reduction routine A described later in step S521. If the move key 305 is ON, the process moves to step S503, and it is checked whether or not the position information input to the touch panel 112 has changed due to a drag operation or the like. If there is no change in information, it is detected in step S504 whether the pen 302 or the like that has been inputting to the touch panel 112 is separated from the touch panel 112. If the pen 302 has been separated, the screen movement process ends in step S505. If the pen 302 has not yet been separated from the touch panel 112, the process returns to step S503 to determine whether the input position information has continuously changed on the touch panel 112. Find out.
[0033]
If there is information change, the process proceeds to step S506, and it is first determined whether or not the position information on the touch panel has changed in the positive y-axis direction shown in FIG. Here, in the case where the input is made in an oblique direction with the pen 302, the process of decomposing the direction vector into vectors in the x and y directions and calculating the magnitude (moving distance) of the vector in the x and y directions is performed. It is performed every time there is an input on the touch panel 112. If the position information has changed in the positive y-axis direction in step S506, the flow advances to step S507 to move the display screen in the positive y-axis direction by a moving amount corresponding to the input operation amount. Thereafter, the process proceeds to step S508, and similarly to step S504, it is detected whether the pen 302 is separated from the touch panel 112. If the pen 302 is separated, the screen moving process ends in step S509. It is checked again whether there is a change in the input position information on the touch panel 112.
[0034]
If the position information has not changed in the positive y-axis direction in step S506, the process proceeds to step S510, and it is detected whether the position information has changed in the negative y-axis direction. If it has changed in the y-axis negative direction, the flow advances to step S511 to perform processing for moving the display screen in the y-axis negative direction by a movement amount corresponding to the input operation amount. Thereafter, in step S512, it is detected whether or not the pen 302 is separated from the touch panel 112. If the pen 302 is separated, the screen moving process is terminated in step S513, and if not, the process returns to step S503, and the touch panel 112 is displayed again. Check if there is any change in the input location information.
[0035]
If the position information has not changed in the y-axis negative direction in step S510, the process proceeds to step S514, and it is detected whether the position information has changed in the x-axis positive direction. If it has changed in the positive x-axis direction, the process proceeds to step S515 to perform processing for moving the display screen in the positive x-axis direction by a moving amount corresponding to the input operation amount. It is detected whether or not the pen 302 has been separated. If the pen 302 has been separated, the screen movement processing ends in step S517. Find out.
[0036]
If it is determined in step S514 that the position information has not changed in the positive direction of the x-axis, the process proceeds to step S518, and the screen is moved in the negative direction of the x-axis by a moving amount according to the input operation amount, similarly to the above procedure. Thereafter, in step S519, it is detected whether or not the pen 302 is separated from the touch panel 112. If the pen 302 is separated, the screen moving process is terminated in step S520. Check if there is any change in the input location information.
[0037]
Next, the screen enlargement / reduction routine will be described with reference to FIG. The process moves to the screen enlargement / reduction routine in step S521 in FIG. First, in step S702, it is detected whether the enlargement / reduction key 306 is ON. If not, normal processing such as selection of various commands on the display screen is performed in step S714. If the enlargement / reduction key 306 is ON, the process proceeds to step S703 to check whether there is a change in the position information input to the touch panel 112 due to a drag operation or the like. If there is no change in information, it is detected in step S704 whether the pen 302 or the like that has been inputting to the touch panel 112 is separated from the touch panel 112. If the pen 302 has been separated, the screen enlargement / reduction processing ends in step S705. If the pen 302 has not been separated from the touch panel 112, the process returns to step S703, and is there any change in the input position information on the touch panel 112? Find out if.
[0038]
If there is information change, the process proceeds to step S706, and it is first determined whether or not the position information on the touch panel has changed in the positive y-axis direction shown in FIG. If the position information has changed in the y-axis positive direction, the process proceeds to step S707, and the display screen is reduced and displayed at a rate corresponding to the input operation amount. After that, the process proceeds to step S708 to detect whether the pen 302 is separated from the touch panel 112 as in step S704. If the pen 302 is separated, the screen enlargement / reduction process ends in step S709. If not, the process proceeds to step S703. Returning again, it is checked whether or not the input position information has changed on the touch panel 112 again.
[0039]
If the position information has not changed in the y-axis positive direction in step S706, the process proceeds to step S710, and it is detected whether or not the position information has changed in the y-axis negative direction. If it has changed in the y-axis negative direction, the flow advances to step S711 to enlarge the display screen at a rate corresponding to the input operation amount. Thereafter, in step S712, it is detected whether or not the pen 302 is separated from the touch panel 112. If the pen 302 is separated, the screen enlargement / reduction processing is terminated in step S713, and if not, the process returns to step S703 and returns to the touch panel. It is checked whether there is a change in the input position information on 112.
[0040]
As can be seen from the flowchart described above, in the first embodiment, once the touch panel 112 is dragged while the movement key 305 or the enlargement / reduction key 306 is pressed, the pen 302 is not released from the touch panel 112 even after releasing the key. As long as the screen moves or the screen enlargement / reduction processing continues. Therefore, it is not necessary to always press the key, and the user of the portable information device can concentrate on only the operation of the pen 302.
[0041]
Further, if the user moves the screen to the outermost portion that can be displayed by moving the screen and performs an operation to further move to the outside of the screen, a process of temporarily issuing a warning indicating that the screen is at the outermost portion is performed. . Similarly, regarding the enlargement / reduction of the screen, a temporary warning is issued even if further enlargement / reduction is performed in the state of the maximum enlargement / reduction screen display. Since these warnings are not automatically displayed on the screen after a certain period of time, no special operation is required to clear the warning display.However, if you want to clear the warning immediately, perform the operation to that effect. It can be turned off.
[0042]
While the move key 305 and the enlargement / reduction key 306 are pressed, icons indicating the “move” and “enlarge / reduce” functions are displayed on the screen, respectively, and the display screen shown in FIG. Since the color of the end portion 601 is a color set for each function, the user does not need to directly look at which key the user is pressing, and performs a desired screen display operation accurately. Can do things. Since the color attached to the display screen edge 601 is a transparent color, the screen operation mode is set, and even if the color is added, the screen display below it can be seen. Further, the above-described display screen movement / enlargement / reduction processing is performed differently when a pen input is performed within the range of the display screen central portion 602 and when a pen input is performed within the range of the display screen end portion 601. When the user drags the inside of the display screen center portion 602 with the pen 302 or the like, the screen continuously moves, enlarges, or reduces in accordance with the amount of the dragging. However, the input of the pen 302 reaches the display screen edge 601. When the pen 302 presses the touch panel 112 without dragging, the screen is continuously moved, enlarged, or reduced at a fixed rate.
[0043]
In addition, various operation functions can be set to the respective keys of the move key 305, the enlargement / reduction key 306, and the key switches (117) 313 to 315 according to the user's preference.
[0044]
(Second embodiment)
In the second embodiment, a configuration capable of performing a “rotation” process in addition to the “movement” and “enlargement / reduction” processes of the display screen described in the first embodiment will be described with reference to FIGS. In the second embodiment, a screen enlargement / reduction routine shown in FIG. 8 is used instead of the screen enlargement / reduction routine shown in FIG. FIG. 9 is a view for explaining a screen rotation routine, FIG. 10 is a diagram showing the external configuration of the portable information device of the second embodiment, and the center and the end of the display screen, and FIG. 11 is a tertiary image displayed on the display screen. It is a figure showing the rotation direction of an original model.
[0045]
The same processing as that of the first embodiment is performed for the display screen movement routine. However, when the enlargement / reduction key is determined not to be ON in step S702 as shown in the flowchart of FIG. In step S801, the process proceeds to the screen rotation routine B.
[0046]
The screen rotation routine will be described with reference to FIG. In the description of the screen rotation routine of the second embodiment, as an example, when a three-dimensional model 1101 as shown in FIG. 11 is displayed on a display device, a process of rotating and displaying the three-dimensional model 1101 will be described. I do. First, in step S902, it is detected whether or not the rotary key 1001 shown in FIG. 10 is ON. If not, the process proceeds to step S921, and proceeds to normal processing such as selection of various commands on the display screen. If the rotation key 1001 is ON, the flow advances to step S903 to check whether or not there is a change in the position information input to the touch panel 112 due to a drag operation or the like. If there is no change in information, it is detected in step S904 whether the pen 302 or the like that has been inputting to the touch panel 112 is separated from the touch panel 112. If the pen 302 has been separated, the screen rotation process ends in step S905. If the pen 302 has not been separated from the touch panel 112, the process returns to step S903. Find out.
[0047]
If there is information change, the process proceeds to step S906, and it is first determined whether or not the position information on the touch panel has changed in the positive y-axis direction shown in FIG. Here, in the case where the input is made in an oblique direction with the pen 302, the process of decomposing the direction vector into vectors in the x and y directions and calculating the magnitude (moving distance) of the vector in the x and y directions is performed. It is performed every time there is an input on the touch panel 112. If the position information has changed in the positive y-axis direction, the process advances to step S907 to perform a screen rotation process in the direction of the arrow 1102 around the x-axis as shown in FIG. 11 with a rotation amount according to the input operation amount. . After that, the process proceeds to step S908 to detect whether the pen 302 is separated from the touch panel 112 as in step S904. If the pen 302 is separated, the screen rotation process ends in step S909. It is checked again whether there is a change in the input position information on the touch panel 112.
[0048]
If the position information has not changed in the positive y-axis direction in step S906, the process proceeds to step S910, and it is detected whether the position information has changed in the negative y-axis direction. If it has changed in the y-axis negative direction, the flow advances to step S911 to perform a screen rotation process in the direction of arrow 1103 around the x-axis as shown in FIG. 11 with a rotation amount according to the input operation amount. Thereafter, in step S912, it is detected whether or not the pen 302 is separated from the touch panel 112. If the pen 302 is separated, the screen rotation process ends in step S913. Check if there is a change in the input location information.
[0049]
If the position information has not changed in the y-axis negative direction in step S910, the process proceeds to step S914, and it is detected whether the position information has changed in the x-axis positive direction. If it has changed in the positive direction of the x-axis, the process proceeds to step S915, and a screen rotation process in the direction of arrow 1104 around the y-axis as shown in FIG. 11 is performed with a rotation amount according to the input operation amount. Thereafter, in step S916, it is detected whether or not the pen 302 is separated from the touch panel 112. If the pen 302 is separated, the screen rotation process is terminated in step S917. Check if there is any change in the input location information.
[0050]
If the position information has not changed in the x-axis positive direction in step S914, the process proceeds to step S918, and the rotation amount corresponding to the input operation amount and the y-axis as shown in FIG. The screen is rotated in the direction of the arrow 1105. Thereafter, in step S919, it is detected whether or not the pen 302 is separated from the touch panel 112. If the pen 302 is separated, the screen rotation process ends in step S920. Check if there is any change in the input location information.
[0051]
As can be seen from the flowchart described above, in the second embodiment, as in the first embodiment, once the touch panel 112 is dragged while the rotary key 1001 is pressed, the pen 302 is moved from the touch panel 112 even after the key is released. The screen rotation process is continued unless the button is released. Therefore, it is not necessary to always press the key, and the user of the portable information device can concentrate on only the operation of the pen 302.
[0052]
While the rotation key 1001 is pressed, an icon indicating the “rotation” function is displayed on the screen, and the color of the display screen edge 601 shown in FIG. 10 is the color set for the rotation function. Therefore, the user does not need to directly look at which key the user is pressing, and can perform a desired screen display operation accurately. Since the color attached to the display screen edge 601 is a transparent color, the screen operation mode is set, and even if the color is added, the screen display below it can be seen. Further, the display screen rotation processing is performed differently when a pen input is performed within the range of the display screen central portion 602 and when a pen input is performed within the range of the display screen end portion 601. When the user drags the inside of the display screen center portion 602 with the pen 302 or the like, the screen continuously rotates according to the amount of the drag movement.
