Abstract

PURPOSE:To realize a cursor position moving control system superior in operability where a cursor is movable in an optional direction by one touch operation, by placing a movable object provided with an optical detector on a panel surface and, moving the movable object in the direction where the cursor is moved. CONSTITUTION:A movable object 2 provided with the optical detector which detects cell information of a panel surface 1 is placed on the panel surface 1 where a pattern is formed, and optical information corresponding to each cell of the pattern on the panel surface 1 is read by this movable object 2. Read optical information is sent to a CPU 4 through an amplifying circuit 3. This CPU 4 has a memory 4A where information of the panel surface 1 where the pattern is formed is stored. The CPU 4 discriminates the sequence of read information, which is changed in accordance with movement of the movable object 2, by information from the memory 4A to detect the movement direction. A cursor moving control signal 5 is sent to a CRT control circuit 6 in accordance with this movement direction to move the cursor displayed on a CRT 7.

Description

TECHNICAL FIELD The present invention relates to a cursor position movement control system for moving a cursor displayed on a CRT screen in a direction corresponding to the movement direction by movement of a movable object placed on a board surface.

Prior Art Conventionally, a cursor on a CRT screen has been moved by instructing the direction of cursor movement, such as up, down, left, right, etc., using limited keys.

Therefore, movement in the diagonal direction requires multiple key operations, which is very cumbersome, and there are many erroneous operations. In addition, there is a method in which the cursor is moved by the amount of rotation of a roller or a ball, but the device itself has moving parts and is susceptible to dirt.

According to the present invention, the surface of the board is divided into a set of patterns each consisting of a set of cells with different optical information such as several types of density, reflectance, or color, and an optical detector disposed on a movable object is used to detect the optical information. By detecting the information and determining the movement order on the pattern of the optical detector, the direction of movement of the movable object can be identified, and cursor movement control corresponding to the amount of movement of the movable object can be performed.

Purpose The purpose of the present invention is to move a cursor position with excellent operability by placing a movable object equipped with an optical detector on a board surface and moving the movable object in the direction in which the cursor is to be moved. This is where the control method is provided.

Another object of the present invention is to provide a highly reliable cursor position movement control system in which a movable object optical detection mechanism does not have a frictional part.

The present invention will be explained below based on examples.

Embodiment FIG. 1 is a conceptual diagram showing an embodiment according to the present invention. 1st
In the figure, 1 is a board surface on which a pattern is formed. Board 1
Optical information corresponding to each cell of the pattern on the board 1 is read by a movable object 2 equipped with an optical detector for detecting cell information of the pattern formed on the board. The read optical information is sent to the central processing unit 4 (hereinafter referred to as CPU) via the amplifier circuit 3.
). The CPU 4 has a memory 4a that stores information about the board l on which the pattern is formed. C.P.
U4 detects the moving direction by determining the order of read information that changes as the movable object 2 moves, based on information from the memory 4a, and transmits the cursor movement control signal 5 to the CRT.
By sending the signal to the control circuit 6, the cursor displayed on the CRT 7 is moved.

Figure 2 is an example in which the board 1 in Figure 1 is divided into square turns. A square noguturn consists of four cells with diagonal lines. The four cells of the example have a reflectance of about 100% at position 1 (as shown by coordinate G-i in FIG. 2).
white), position 2 is approximately 60% (light gray), position 3 is 30%
(manufacturing method), has optical information of positional 0% (black) of 4.

Therefore, suppose that the movable object is moved from point A to point B as shown in FIG. This movement is detected by the optical detector 2, and the information shown in FIG. 3 is obtained as a change in cell information.

As is clear from FIG. 3, the following rules are observed in the order of patterns detected by the optical detector 2 due to the movement of the movable object. i.e. top → bottom, bottom → top, left → right,
Regarding right→left, the following rules (1) to (4) in parentheses are found.

(1) Move from top to bottom from cell 2 or 3 → (4 → 1
) → 2 or 3° (2) To move from below to above, use cell 2 or 3 → (1 → 4
) → 2 or 3, (3) To move from left to right, select cell 1 or 4 → (2 → 3) →
1 or 4, (4) To move from right to left, select cell l or 4 → (3 → 2) →
1 or 4° These are the relationships between adjacent cells of adjacent patterns. Therefore, by paying attention to this change information, it is possible to know from one pattern to which direction the pattern has moved next. Therefore, in this embodiment, when the movable object moves from the coordinate D-) (point A) on the board surface to the coordinate A-i (point B) as shown in FIG. Since this change occurs three times, it is sufficient to generate a cursor movement control signal in accordance with this change and move the cursor on the CRT screen.

As an example of reverse movement, consider movement from point B to point A on the board. According to the above-mentioned rule, the cursor movement signal will be generated six times to the right and three times downward.

Furthermore, the number of coordinates of the pattern formed on the board surface can be reduced regardless of the number of rows and columns displayed on the CRT screen, and in this case, the number of coordinates on the board surface can be reduced. This can be done by lifting it off the board and repeating the same operation. In this case, by dividing into six cells 1 to 6, movement in six directions can be detected.

For example, as shown in FIG. 5(a), when moving from coordinate C-ni (point 0) to coordinate A-i (point D),
The cell information shown in b) can be obtained. From this,
In the same figure (as shown by the arrow in CJ, it is understood that the movement is performed to the next pattern. In other words, from the upper left cell, the movement to the next pattern cell (2→5) changes twice, and from the left cell. Moving to the cell of the next pattern (4→3) appears twice. Therefore, in this case, a cursor movement control signal is generated and the cursor is moved twice to the left pattern and twice to the left pattern. All you have to do is control it.

In addition, in the above embodiment, the movable object 2 having an optical detector
Although the explanation has been given according to an example in which the movable object 2 is moved, the movable object 2 may be fixed and the board 1 may be movable.

That is, it is sufficient if the structure is configured so that relative movement between the two occurs.

Effects As described above, according to the present invention, it is possible to provide a highly reliable cursor position control system with excellent operability that allows movement in any direction with a - operation.
