At the same time, it is displayed on the display unit 4. And RAM
The processing result stored in the storage device 5 is stored in a storage destination in the storage device 6 designated by the input unit 3.

When the CPU 2 detects a position signal instructed to be pressed on the touch panel when executing an object specifying process (see FIG. 3) described later, the CPU 2 stores the object coordinate table 6a stored in the storage device 6 in the RAM 5 The object displayed at the position closest to the detected pressed position is designated by referring to the data set in the object coordinate table 6a. Here, the object is a GUI (Graphical User Inter
face) In the environment, instruct a predetermined operation such as a component such as an icon and a button displayed on the screen and a text (hot text) linked to other information in the displayed data. Refers to the display area that functions as a switch.

The CPU 2 determines whether or not the designated object can be dragged, and if so, moves the object according to a drag operation input to the touch panel of the input unit 3. If the dragging is not possible, it is determined whether the detected pressing instruction is the first pressing instruction or the second pressing instruction. In the case of the first pressing instruction, the display of the designated object is switched to the display of the selected state and the second pressing instruction is performed. In the case of a pressing instruction, processing corresponding to the object is executed.

The input unit 3 includes a keyboard having cursor keys, numeric input keys, and various function keys, and a display unit 4.
And outputs to the CPU 2 a signal for pressing a key pressed on the keyboard and a position signal for instructing the touch panel to be pressed with a stylus pen or the like. The display unit 4 includes a liquid crystal display screen or the like, and displays display data input from the CPU 2.

The storage medium 7 is fixedly provided in the storage device 6 or is detachably mounted. The storage medium 7 includes various application programs, object designation processing programs, And data processed by various processing programs.

FIG. 2 is a diagram showing an object coordinate table 6a stored in the storage device 6 shown in FIG.
As shown in FIG. 2, "object coordinates" and "object attribute information" are stored in the object coordinate table 6a.
Are stored. The “object coordinates” include various objects (scroll boxes 41, 31, scroll buttons 32, 33, 42, 43, menu buttons on the menu bar 20, tool buttons on the toolbar 21, As the display position coordinates of the hot text 50 (see FIGS. 4 and 5 and various icons), for example, “(X1, Y
1) → (X2, Y2) ”, the upper right coordinates and the lower left coordinates of each object are set.

In the "object attribute information", data of the object displayed at the coordinate position set in the "object coordinates" is set. For example, when the object is an object to be dragged, " If the object is set to “drag operation enabled” and is not dragged, “drag operation disabled” is set.

The display position of each object changes with the change or movement of the display range displayed on the display unit 4, and the coordinate values of various objects stored in the "object coordinates" of the object coordinate table 6a. Also change.

Next, the operation will be described. The object designation process executed by the CPU 2 of the portable terminal device 1 will be described with reference to the flowchart shown in FIG.

First, the CPU 2 determines whether or not a pressing instruction with a stylus pen or the like is detected by the touch panel of the input unit 3 (step S1). If the pressing instruction is not detected, step S1 is repeated until the pressing instruction is detected, and if the pressing instruction is detected, the coordinates of the pressed position are acquired (step S2).

Then, the CPU 2 develops the object coordinate table 6a stored in the storage device 6 in the RAM 5, and refers to the data set in the "object coordinates" of the object coordinate table 6a (step S2).
3) Specify the object displayed at the position closest to the coordinates obtained in step S2 (step S4).

Further, the CPU 2 refers to the data set in the "object attribute information" of the object coordinate table 6a to determine whether or not the object specified in step S4 can be dragged (step S4).
5). If dragging is possible, the coordinates of the position pressed by the drag operation are sequentially obtained (step S).
6) The object is moved to the acquired coordinates (step S7), and it is determined whether or not the object is no longer pressed (the drag is completed) (step S8).

If the pressed state is continued, the process of step S8 is repeated until the pressed state is stopped, and if the pressed state is stopped, the process returns to step S1 to determine again whether or not the pressing instruction is detected. I do.

On the other hand, if it is determined in step S5 that dragging is impossible, it is determined whether or not the pressing detected in step S1 is the second pressing (step S9). When determining whether the detected pressing instruction is the first time or the second time in step S9, for example, the pressing is performed at a position within a predetermined distance from the previous pressing position within a predetermined time after the previous pressing instruction is detected. If it is a pressed instruction, it is determined that it is the second pressing. Also, for example, when a pressing instruction is given to a position where the same object as the object specified by the previous pressing instruction is specified in the process of step S4,
The pressing may be determined to be the second pressing.

If it is determined in step S9 that the pressing is not the second pressing, the CPU 2 determines that the pressing is the first pressing and waits until the pressing is stopped. (Step S
10). If the object is no longer pressed, the display state of the object specified in step S4 is switched to a selected state (for example, a reverse display state) (step S11).
It returns to step S1.

If it is determined in step S9 that this is the second pressing, the process waits until the pressing is stopped (step S12). When it is no longer pressed, a process corresponding to the object specified in step S4 is executed (step S13), and the process returns to step S1.

FIG. 4 is a diagram showing a specific example of a screen displayed on the display unit 4. As shown in FIG. In FIG. 4, for example, a menu bar 20 having various menu buttons, a toolbar 21 having various tool buttons, a scroll box 4
1. Objects such as a vertical scroll bar 40 having an upper scroll button 42 and a lower scroll button 43, a horizontal scroll bar 30 having a scroll box 31, a right scroll button 32 and a left scroll button 33, and a plurality of hot texts 50 are displayed. Included in the screen.

As shown in FIG. 4A, for example, when a position A on the screen which is not on the object near the scroll box 41 is pressed, the scroll box 41 is designated as the object closest to the pressed position A. .
When the drag operation is performed from the position A to the position A ′ as shown in FIG. 4B, the scroll box 41 is moved in accordance with the direction and the distance from the position A to the position A ′ (indicated by a dotted arrow in the figure). Moves in the direction and distance indicated by the solid arrow in the figure. That is, even if the scroll box 41 is not dragged, the scroll box 41 can be moved by performing a drag operation in the vicinity thereof.

As shown in FIG. 5A, for example,
When a position B on the screen that is not on the object near the upper scroll button 42 is pressed, the upper scroll button 42 is designated as the object closest to the pressed position B. Then, as shown in FIG. 5B, the scroll button 42 is switched to a display state indicating a selected state (for example, a reverse display state). Then, when the position B is pressed again, a process corresponding to the upper scroll button 42 is executed. That is, the display range can be scrolled upward without pressing the position of the upper scroll button 42 accurately.

In addition to the scroll buttons of the scroll bar, for example, in the display screen shown in FIG. 5, the buttons provided in the menu bar 20 and the toolbar 21 and the objects such as the hot text 50 are accurately displayed. Even if the object is not pressed on the object, and if the object is not on another object, the object can be designated and operated by pressing the screen near the object.

As described above, when the CPU 2 detects a press by the touch panel of the input unit 3, the CPU 2 acquires the coordinates of the pressed position, refers to the object coordinate table 6a, and displays the coordinates at the position closest to the coordinates. Specify the object that is If the specified object is a draggable object, the direction of the drag operation input to the touch panel of the input unit 3 is determined.
Moves the specified object according to the distance.

If the specified object is a non-dragable object, it is determined whether the detected pressure is the first time or the second time. The display state of the selected object is switched to the display state indicating the selected state, and waits until the next press is detected. If it is the second press, a process corresponding to the specified object is executed.

Therefore, even if the position of an accurate object is not pressed, if the vicinity of the object is pressed, the object closest to the pressed position can be designated, and the "object attribute information" corresponding to the object can be specified. Since the operation according to the setting of the above can be executed, the display screen is small, and the operation of the object in the portable terminal device 1 in which it is difficult to perform the accurate object operation becomes easier.

When pressed once, the object is switched to the display of the selected state, and when pressed twice, the operation corresponding to the object is executed. The specified object can be confirmed at the time of performing. Therefore, operation due to incorrect object operation can be prevented.

In the above-described embodiment, the pressing instruction input on the touch panel integrated with the liquid crystal display device of the portable terminal device 1 has been described. However, the present invention is not limited to this. It is also possible to apply to input of pressing instructions on a touch panel or the like of a stationary terminal device, and also to application of an instruction with a pointing device such as a mouse, a joystick, or a trackball in a stationary terminal device or the like. It is possible.

In the above embodiment, when an object that cannot be dragged is specified, the display state is switched to reverse display or the like as the selection state display. May be changed, or, for example, a ruled line surrounding a specified object may be displayed.
Alternatively, the ruled line may be displayed in a blinking manner, and the display is not particularly limited as long as the user can confirm that the object has been selected. The display state indicating the selection state may be different depending on the type of the object.

Further, even when a draggable object is specified, the display state of the specified object may be switched to a display state indicating a selected state. Can be changed as appropriate without departing from the spirit of the present invention.

[0052]

According to the first, fifth, and sixth aspects of the present invention, the object closest to the operation position is determined,
Since the operation corresponding to the object is performed, the user need only operate the vicinity of the desired object without operating the object accurately. For example, operability can be improved, for example, it is easier to operate an object that is difficult to perform accurately on a portable terminal device or the like having a small display screen.

According to the second aspect of the present invention, the object closest to the operation position can be determined, and the operation based on the attribute of the object can be executed. For example, by performing a drag operation near a draggable object, the object can be dragged, and the operation of the object becomes easier.

According to the third aspect of the present invention, the display state is switched and displayed in different display states, so that the user can easily confirm the object to be operated. Therefore, for example, even when an object different from the desired object becomes an operation target, it is possible to easily confirm that, and it is possible to prevent an operation due to an operation of an erroneous object.

According to the fourth aspect of the present invention, when an operation is performed on an object in a state in which the user can confirm that the object is an operation target by switching the display state, the object is displayed. Since the corresponding operation is executed, the operation due to the operation of the wrong object can be prevented.
