Abstract

PURPOSE:To specify the moving direction and the speed of a cursor only by an operation stick by converting the moving distance of the operation stick to the moving speed of the cursor. CONSTITUTION:The device is provided with the operation stick 34 which can be inclined in an optional direction and a converting means 44 for detecting the moving distance of the operation stick 34 in accordance with the inclination of the operation stick 34 and calculating the moving speed of the cursor based on the moving distance. Information on the X co-ordinate and the Y co-ordinate of the operation stick 34 converted to a voltage is inputted so that the moving direction and the moving distance of the stick which is observed from the fixed position of the stick may be calculated by the moving direction and the moving distance calculating device 44, and then the data 47 about the moving direction and the moving distance of the stick is transferred to a cursor moving unit 32 by the device 44. And the moving direction of the stick is converted to the moving direction of the cursor so that the moving distance may be converted to the moving speed of the cursor by the cursor moving unit 32, and then the cursor on the display screen 33 is moved by the unit 32. Thus, the moving direction and the moving speed of a position instructing mark is specified by an operator.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for specifying a position on a screen. The present invention relates to an on-screen positioning device for specifying the position of a cursor on a screen.

[Prior art] Conventionally, this type of on-screen position specification method involves a bar and contacts arranged in a circle around the bar, and detecting which contact is in contact with the bar and converting it into an electrical signal. The user tilts the rod to bring the rod into contact with the contact, and the detection means detects which contact the rod has contacted, thereby converting the direction in which the rod is tilted into an electrical signal. , was moving the cursor in that direction. Another conventional example includes a sphere, a frame provided to freely rotate the sphere, and a detection means for detecting the rotation distance and rotation direction of the sphere surface due to the rotation of the sphere and converting it into an electric signal. However, a method has also been known in which the user rotates the sphere to move the cursor according to the rotation distance and rotation direction of the sphere.

FIG. 2(a) shows a perspective view, a partial cross-sectional view, and a top view of one example of the former type of conventional on-screen position designation method. (
Shown in b) and (c), respectively. According to this position specification method, the input device 1l and the cursor movement unit 12 that moves the cursor based on the output from the human power device 11,
The display screen 13 displays a cursor based on the output from the cursor movement unit 12. The human power device 11 includes an operating rod 14, a joint 15 that holds the operating rod 14 so that it can be tilted in any direction on a plane, an outer frame 16, and a circular arrangement around the operating rod 14. It includes a contact group 17 and a detection means 18 that detects which contact the operating rod 14 has contacted. The cursor moving unit 12 moves the cursor in a direction corresponding to the position of the contacted contact based on the output from the detection means 18 .

The user of this position designation method brings the operating rod 14 into contact with one of the contacts of the contact group 17 by tilting the operating rod 14 in a desired direction. The detection means 1 detects which contact point the operating rod has touched, and transmits data 19 on the direction in which the operating rod 14 is tilted to the cursor moving unit 12.

The cursor movement unit 12 converts the data of the direction in which the operating rod 14 is tilted into the movement direction of the cursor, and
Move the cursor above.

A perspective view and a partial cross-sectional view of one example of the latter type of conventional on-screen position designation system are shown in FIGS. 3(a) and 3(b). This position designation system includes a human-powered device a21, a cursor moving unit 22 that moves a cursor based on the output from the human-powered device 21, and a display screen 23 that displays the cursor based on the output from the cursor moving unit 22.

The human power device 21 includes a sphere 24, an outer frame 25 that can freely rotate the sphere 24, and a detection means 26 that detects the rotation distance and rotation direction of the sphere 24 and converts it into an electric signal. The cursor unit 22 moves the cursor on the display screen 23 in a direction corresponding to the direction of rotation of the sphere 24 by a distance corresponding to the rotation distance based on the output from the detection means 26 .

The user of this position designation method rotates the sphere 24 by grasping and moving the user-powered device with his or her hand while keeping the sphere 24 in contact with the surface of the desk. The detection means 26 converts the rotation distance and rotation direction of the sphere 24 into electrical signals, and transmits data 27 on the rotation distance and rotation direction of the sphere 24 to the cursor movement unit 22.

The cursor moving unit 22 converts the rotation direction and rotation distance data converted into electrical signals into a cursor movement direction and movement distance, and moves the cursor on the display screen 23.

[Problems to be solved by the invention] Of the above-mentioned conventional on-screen position designation methods, the second
In the cases shown in Figures (a) to (c), the human-powered device itself can be operated while fixed on the desk, so it has the advantage of requiring only a relatively small area; Since the movement speed cannot be measured, in order to accurately indicate the desired position, it is necessary to set the movement speed slowly in advance.In this case, the disadvantage is that it takes a long time to move the cursor to the desired position t,'. arise. On the other hand, in order to shorten the moving time, it is necessary to set the moving speed faster in advance, and in this case, there is a drawback that it becomes difficult to accurately indicate the desired position.

On the other hand, in the case of low-pitched sounds, the rotating direction of the human-powered device's sphere corresponds to the cursor's moving direction, and the rotating speed of the sphere corresponds to the cursor's moving speed. Although it is possible to shorten the length, there is a drawback that the installation area becomes large because the human-powered device itself needs to be moved over a wide range.

SUMMARY OF THE INVENTION An object of the present invention is to provide a position specifying device that can indicate the direction and speed of movement of a cursor with a relatively small footprint.

[Means and effects for solving the problem] The gist of the present invention is to provide an input unit for instructing the movement of a cursor, a display unit for displaying the cursor on the screen, and a display unit for displaying the cursor on the screen based on instructions given to the input unit.
