DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates has a visual user interface relates to the menu item selection device to select with the mouse to the user by presenting a menu on the screen.

[0002]

2. Description of the Related Art In a conventional menu item selection device, a mouse cursor can be moved to a front range on a screen, and a mouse cursor can enter even an unselectable item.

[0003]

In this conventional menu item selection device, the user cannot recognize which item cannot be selected only by moving the mouse cursor, and the user cannot select the item until the user performs a selection operation. There was a problem that it was not possible to recognize that selection was not possible.

[0004]

A menu item selecting device according to the present invention comprises a mouse, a display, a mouse cursor display section for displaying a mouse cursor at a position on the display moved by the mouse, and a current mouse. and mouse Casa position acquisition unit that acquires a position of Casa, select
Menu items that include both selectable and non-selectable items
A selection prevention area acquisition unit that recognizes an area of the selection prohibition item, a selection prevention area intrusion determination unit that determines whether a mouse cursor has entered the area, and a mouse car.
In response to a request to the
A mouse cursor position resetting unit for setting the position of the cursor outside the region .

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of one embodiment of the present invention. In this embodiment, the mouse cursor position acquisition unit 1 is used.
A mouse cursor display unit 2, a mouse cursor position resetting unit 3, a selection prevention area intrusion determination unit 4, a menu item selection prevention area acquisition unit 5, a mouse cursor position storage unit 6,
It is composed of a mouse 7 and a display 8.

FIGS. 2 and 3 are flowcharts of the present embodiment. FIG. 2 is a flowchart showing the specific item selection prevention processing. FIG. 3 is a flowchart of the selection prevention area intrusion determination unit 4.

FIG. 4 and FIG. 5 are diagrams showing screens of the present embodiment.

When the mouse is moved or a menu is selected, a notification (message) to that effect comes from the OS, and the application performs processing corresponding to each message.
There is S. In the present embodiment, such application on the OS is assumed. The processing flow will be described based on this.

When the operator operates the mouse 7 and moves the mouse cursor on the screen to select an item, O
S notifies the system of a message of mouse movement. Then, the process of FIG. 2 is performed. At that time, first, the coordinates of the area of the selection prohibition item are acquired from the menu item selection prevention area acquisition unit 5 (step 201). Next, the coordinates of the current mouse cursor are acquired by the mouse cursor position acquisition unit 1 (step 202), and whether or not the current mouse cursor is within the selection prohibited area is determined by the selection prevention area intrusion determination unit 4 (step 203). ). If the current mouse cursor is in the selection prohibited area, the mouse cursor position resetting unit 3 sets the previous mouse cursor position as a new mouse cursor position (step 204). If the current mouse cursor is not in the selection prohibited area, the coordinates of the current mouse cursor are copied to the save area by the mouse cursor position storage unit 6 (step 205). This coordinate value becomes the previous mouse cursor position when the next mouse movement message processing is performed. This processing ends when the selection processing ends.

The selection prevention area intrusion determination unit 4 determines whether the mouse cursor is within the item rectangle based on the acquired coordinates of the mouse cursor and the coordinates of the selection prevention area rectangle. This will be described with reference to FIG.

First, in step 302, it is determined whether or not the mouse cursor falls on the rectangular left frame of the selection prevention area. If the X coordinate of the mouse cursor is smaller than the X coordinate of the left side of the item rectangle, the mouse is not in the area, so that step 3
Move to 07. The X coordinate of the mouse cursor is the left X of the item rectangle
If it is larger than the coordinates, there is a possibility that the mouse is within the rectangle, so the process proceeds to step 303.

Next, in step 303, it is determined whether or not the mouse cursor is over the rectangular right frame. If the X coordinate of the mouse cursor is larger than the right X coordinate of the item rectangle,
Since the mouse is not in the area, the process proceeds to step 307. If the X coordinate of the mouse cursor is smaller than the right X coordinate of the item rectangle, there is a possibility that the mouse is within the rectangle, so the process proceeds to step 304.

Next, in step 304, it is determined whether or not the mouse cursor is over the rectangular upper frame. If the Y coordinate of the mouse cursor is larger than the upper Y coordinate of the item rectangle,
Since it is not within the mouse area, the process proceeds to step 307. If the Y coordinate of the mouse cursor is smaller than the upper Y coordinate of the item rectangle, there is a possibility that the mouse is within the rectangle, so the process proceeds to step 305.

Next, at step 305, it is determined whether or not the mouse cursor is over the rectangular lower frame. If the Y coordinate of the mouse cursor is smaller than the lower Y coordinate of the item rectangle,
Since the mouse is not in the area, the process proceeds to step 307. If the Y coordinate of the mouse cursor is larger than the lower Y coordinate of the item rectangle, the process moves to step 306 because the mouse is within the rectangle. In this way, when the user reaches step 306, the mouse is within the rectangle. When the user reaches step 306, the mouse is not within the rectangle.

Next, the drawings of this embodiment will be described. Consider a case where an item is selected by a drop-down menu. The drop-down menu is a menu for selecting an item in a menu bar. If there are more menus below the items in the menu bar, submenu items open. Move the mouse cursor inside the rectangle of the item and press the mouse button to select that item.

In FIGS. 4 and 5, "Yakisoba" is a selection prohibition item. In FIG. 4, the mouse cursor is on the left side of the selection prohibited item "Yakisoba". At this time, even if the user moves the mouse cursor to select "Fried noodles", the mouse pointer is set to the position immediately before entering the prohibited item as described above, so that the pointer is set to the "Fried noodles" item as shown in FIG. Stay outside of the area. Since the pointer cannot be positioned in the area of “yakisoba”, it is understood that the user cannot immediately select “yakisoba”.

[0018]

As described above, according to the present invention, the mouse cursor is not inserted into the items whose selection is prohibited, so that the user can immediately understand the items that the user should not select when selecting the items. effective.
