Abstract

PROBLEM TO BE SOLVED: To reduce the burden of an operator and to secure the pleasant selection of icons by measuring the distance between a cursor and every icon if the stoppage of the cursor is judged and deciding an icon having the shortest distance to move the cursor to this icon. SOLUTION: When the key of a remote control is pushed or the control 1 is moved, a photodetection part 2 converts the optical signals received from the control 1 into the information on electric signals and sends this information to a remote control information processing part 4. The part 4 judges the push of the key of the control 1 or the movement of the control 1, and a cursor shift processing part 5 moves a cursor 22. When the shift of the cursor 22 is finished (stopped), a cursor-icon distance measurement part 6 calculates the distance between the cursor 22 and every icon 23 on a screen. A shortest distance icon decision part 7 decides an icon 23 having the shortest distance, and the part 5 moves the cursor 22 to the decided icon 23.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for displaying icons on a display screen such as a computer system for realizing a graphical user interface or a television system for performing menu operations while watching the screen.

[0002]

2. Description of the Related Art In recent years, in a system for giving a presentation using a computer, a system for operating with a remote controller and a system for selecting a menu on a screen of a television with the remote controller are increasing. . Conventionally, the operator moves the cursor on the computer screen by pressing the keys on the remote control or moving the remote control up, down, left, and right, and by placing the cursor over the icon, the icon is in a semi-selected state. Then, the operator selects the icon by confirming the reverse display and pressing the selection key.

[0003]

However, in the conventional method, the operator has to place the cursor on the small icon, and it is burdensome for the operator to select the icon with the remote controller which is difficult to operate in detail. I was having trouble with the presentation.

The present invention has been made in view of the above points. By performing the processing of moving the cursor to the icon closest to the position where the cursor stops, the operator does not need to accurately place the cursor on the icon. An object of the present invention is to provide an icon display device in which the burden is reduced and comfortable icon selection is possible.

[0005]

In order to achieve the above object, an icon display device of the present invention comprises a plurality of icons and a display means for displaying a cursor for pointing one of the plurality of icons. A moving means for moving the cursor, a means for measuring a distance between the cursor and each icon, a means for determining an icon having the shortest distance among the icons, and a cursor moving on the icon having the shortest distance. And means.

According to the icon display device of the present invention having the above-described configuration, the operator moves the cursor to the vicinity of the icon to be selected so that the distance between each icon and the cursor is measured when the movement is completed. Then, the cursor moves to the icon with the shortest distance. Therefore, the operator does not have to accurately place the cursor on the icon, and the burden is reduced and comfortable icon selection is possible.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a basic partial configuration of an embodiment of an icon display device of the present invention. In the figure, 1 is a remote controller and 2 is a remote controller light receiving unit. Reference numeral 3 is a microcomputer, and as its internal configuration, 4 is a remote controller information processing section for processing data received by a remote controller light receiving section, 5 is a cursor movement processing section, 6 is a cursor / icon distance measuring section, and 7 is the shortest distance icon determination. Reference numeral 8 is a cursor / icon display portion. Reference numeral 9 is a display memory unit, 10 is a display control unit, and 11 is a display. FIG. 2 is a diagram showing a display screen of the present invention.
20 is a display screen. Reference numeral 21 is an icon, 22 is a cursor, and 23 is an icon determined to be closest to the cursor.

Next, the operation will be described with reference to FIGS. 1 and 2. When the operator moves the cursor 22 on the display screen 20 displayed on the display 11 by pressing a key on the remote controller 1 or moving the remote controller 1, the remote controller 1 sends an optical signal corresponding to the pressed key or movement. Output. The light receiving unit 2 receives the optical signal of the remote controller 1, converts the optical signal into information of an electric signal, and transmits it to the remote controller information processing unit 4. From the information, the remote controller information processing unit 4 determines the key pressed by the remote controller or the movement of the remote controller. The cursor movement processing unit 5 moves the cursor 22 based on the information determined by the remote controller information processing unit 4. Then, when the movement of the cursor 22 ends (stops), the cursor movement processing unit 5 notifies the cursor / icon distance measuring unit 6 of the information.

The cursor / icon distance measuring unit 6 calculates the distance between the cursor 22 and each icon 21 on the screen display. The shortest distance icon determination unit 7 determines the icon 23 with the shortest distance as a result calculated by the cursor / icon distance measurement unit 6, and notifies the cursor movement processing unit 5 of the position information of the determined icon 23. And
The cursor movement processing unit 5 moves the cursor 22 to the position of the icon 23. Cursor / icon display 8
Inverts the display of the icon 23 moved by the cursor and writes it in the display memory unit 9 together with other icons and the cursor. Then, the display control unit 10 reads the content of the display memory unit 9 and displays it on the display 11.

Next, the operation of the microcomputer of FIG. 1 will be described with reference to the flowchart of FIG. First, when the remote controller is operated, the cursor is moved in step S31. In step S32, it is determined whether or not the movement of the cursor is completed. If not completed, step S31 is repeated to continue the movement of the cursor. If it is determined that the operation is completed, it is determined in step S33 whether the cursor is on the icon. If the cursor is on the icon, the icon is highlighted in step S37, and the process ends. On the other hand, when the moved cursor is not on the icon, the distance between the cursor and each icon is calculated in step S34. Then, in step S35, the icon closest to the cursor is determined. The cursor is moved onto the icon determined in step S36. When the cursor moves onto the icon, the icon is highlighted in step S37, and the process ends.

In the above embodiment, the cursor movement processing unit 5 automatically moves the cursor onto the icon determined by the shortest distance icon determination unit 7. However, when the operator instructs the remote control key, The cursor may move only when instructed.

[0012]

As is apparent from the above description, according to the icon display device of the present invention, the operator moves the cursor near an icon to be selected, and when the movement is completed, each icon and the cursor are moved. The distance of
The cursor moves to the icon with the shortest distance. Therefore, the operator does not have to accurately place the cursor on the icon, and the burden is reduced and comfortable icon selection is possible.
