DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for controlling horizontal rotation of a cursor, and more particularly to a method of rotating an X-axis movable optical grid and a Y-axis movable optical grid to an appropriate angle, and further allowing the cursor to be moved arbitrarily. And a method of controlling the cursor.

2. Description of the Related Art Cursor control techniques in traditional computer displays include keyboards, mice, trackballs, touch control displays, light pens, and the like. However, in general, these traditional cursor controls have been inconvenient for moving and positioning the cursor. For example, using a keyboard to move the cursor has not been effective. On the other hand, when a traditional mouse is used to control the movement of a cursor, it must be operated on a mouse pad, the user's arm also operates to operate, and the forearm moves during the twist operation However, the rear arm also subsequently moved, resulting in arm movements that were incompatible with ergonomics, and were therefore prone to pain in the arm after prolonged use.

As shown in FIG. 1, US Pat. No. 4,935,728 describes a rectangular opening 136a formed in an upper plate 134a of an outer case 132a. The rectangular opening 136a serves as a margin for the gripping member. The optical encoder is provided with opaque portions and transparent portions alternately. For an optical encoder with phase A and phase B, 320 phase signals must be generated per inch (excluding the center), and the minimum distance between transparent and opaque portions on the optical encoder is 0,1. 16mm (25.4mm
/160=0.16 mm). Considering the phase difference of 90 degrees between phase A and phase B, the distance is 0.08 mm
Is equal to That is, a large operation range is required to slightly move the cursor. In addition, when the hardware sends a pulse signal, it must travel a distance of 0.08 mm. Therefore, 320 in the range of 25.4 mm
The precise operation of sending pixel signals was required. Therefore, the known technique required a precise parallel structure of the rectangular aperture and the optical encoder in manufacturing and assembly. Also, each dot in the Y-axis direction of the rectangular opening may have an incorrect X-axis margin value, and similarly, each dot in the X-axis direction of the rectangular opening may have an incorrect Y-axis margin value. was there.

In order to support different resolutions depending on the display, for example, 800 × 600 and 1280 × 1204, the following methods are employed. 1. Increase the size of the grip-type control member. 2. Reduce the distance between each opaque part and transparent part of the optical encoder. In the former method, since the length of the grip-type control member is increased, the user is tired by the operation, and the operation range is limited in the left-right direction. The latter method has a problem that the effective displacement becomes very small due to the reduced distance, so that a signal cannot be generated correctly at each operation. Furthermore, the latter has the potential for the positioning device to generate two or three pulse signals during each operation. A design that reduces the distance of the optical encoder can reduce the range of operation of the hand-held control member of the user's hand, and the design is particularly applicable to the use of a remote controller for multimedia systems, making it easier to operate. It is convenient and has the effect of preventing the user from getting tired. If the operating range of the grip-type control member is smaller than 16 mm, the movement of the finger is very limited.

[0032]

12A to 12F show the structure and signal waveforms of a movable photoencoder and a photodetector in a positioning device according to the present invention. In this embodiment, two phototransistors are used to detect the light flux of the LED.
The photo encoder 4 has two rows of print pattern lines as shown in FIG. In each print pattern line, opaque portions and transparent portions having a fixed width are alternately arranged, and there is a phase difference of 90 degrees between them.
When the photo encoder 4 is opposed to the photo detector 6, FIG.
When it is moved as shown in C, the light generated by the LED 61 is transmitted to the movable photo encoder 4 and the measurement photo encoder 62.
Is detected by the photodetector 63 via Thereby, the photodetector 63 generates a series of binary pulse signals and transfers the signals to the control circuit board 18. By the operation of the control circuit shown in FIG. 14 and the control flows shown in FIGS. 15 to 17, the operation direction of the movable photo encoder is detected according to the binary pulse signal.

The X-axis photo encoder 4 has a transparent end 4
C1 and the other end is an opaque end 4C2. Transparent and opaque ends are the left margin X of the X-axis photo encoder
min and the right margin Xmax. Similarly, the Y-axis photo encoder has a left margin and a right margin. This design allows each margin directly obtained from the photoencoder to provide a digital signal. Obviously, the present invention, unlike the known art, has the effect of simplifying the design of the control program for the decision.

Alternatively, the photo-encoder 4 in A in FIG. 12 is connected to the end 4 in A in FIG.
Instead of C1 and 4C2, it can be changed to one having an end 4C3 in which a transparent line and a mask line are connected. In operation, after reaching the margin of the photo encoder 4 and exceeding a quarter period, the phases of the signals XA and XB change simultaneously. Conversely, when it has not reached the photoencoder margin, the phases of signals XA and XB do not change at the same time. Then, the control circuit of the present invention detects whether the phases of the signals XA and XB have simultaneously changed, and determines whether the photo encoder has reached the margin.

Table 1 below shows that the computer system connected to the cursor positioning device of the present invention uses signals XA and XB.
Receive the signals XA and XB
Indicates that it is possible to determine whether the operation direction of the positioning device is X ⁺ or X ⁻ by the binary value of. The computer flags Xmax and flag Xmin, signal X ⁺ and X ^- by obtaining, then stores the status of the flag in the register.

[Table 1]

Referring again to FIG. FIG.
12B is a perspective view of an X-axis photodetector 6 suitable for use with the photoencoder shown in FIG. This photodetector has an LED 61, a fixed measurement photoencoder 62 and a phototransistor 63. The component arrangement of the photodetector 6 and the movable photoencoder 4 is indicated by C in FIG. As shown in the figure, the movable photo encoder 4 is disposed between the fixed measurement photo encoder 62 and the LED 61. Therefore, L
The light beam transferred from the ED 61 reaches the movable photo encoder 4 via the phototransistor 63 or is blocked by the photo encoder. In FIG. 12, as indicated by D,
The fixed measurement photo-encoder 62 has a series of print patterns including transparent parts and opaque parts alternately arranged, and the width of the print pattern corresponds to the print pattern of the movable photo-encoder 4. In the preferred embodiment of the present invention, the movable photo encoder 4 is very close to the fixed measurement photo encoder 62, so that the luminous flux generated by the LED 61 reaches the photo transistor 63 through the movable photo encoder 4 without light diffusion. In FIG. 12, E indicates a series of pulse signals XA and XB generated by the photodetector device.

It should be noted that the movable photo encoder 4 of the present invention has a printed pattern in which transparent portions and opaque portions are alternately arranged. It is close in location and can generate on and off signals. With such a special design, the pitch of the movable photo encoder 4 can be 320 patterns per inch. Well-known technology is laser L
EDs were required to obtain high pitches, and traditional photodetectors had light diffusion problems.
The problems of these known techniques can be easily overcome by the present invention.

FIG. 14 is a detailed control circuit diagram of the present invention. As shown in FIG. 12, it has four sets of photodetection circuits. In this embodiment, the X-axis phase signal is detected by two light detection circuits 81 and 81a. The first X-axis light detection circuit 81 includes an LED 61a, and the LED 61a generates a light beam.
b. The second X-axis light detection circuit 81a is LE
D61b, which generates a light beam that is detected by phototransistors 63c and 63d. The Y-axis phase signal is detected by the two light detection circuits 82 and 22a. The first Y-axis light detection circuit 82 includes an LED 71a,
The LED 71a generates a light beam, which is detected by the phototransistors 73a and 73b. The second Y-axis light detection circuit 82a includes an LED 71b, which generates a light beam, which is detected by phototransistors 73c and 73d. The detected X-axis and Y-axis phase signals are sent to the processing circuit 83 for further processing. One switch circuit 8
4 is electrically connected to the processing circuit 83, and the switch circuit 8
4 includes a left switch 11a, a right switch 12b, and a center switch 13c. The control circuit is provided together with a voltage stabilizing circuit 85 for providing a stable power supply. One output circuit 86 is provided for amplifying the output signal sent from the processing circuit 83 and sending the amplified output signal to a host computer (not shown in the figure) via a transfer line. As shown in FIG. 15, the computer first sets the transfer rate, start bit, end bit, and data length of the communication port RS232 in step F2.
In step F3, all flag statuses, registers, and related values for determining the operation speed are cleared.
Thereafter, the computer outputs the phase signals XA, XB, YA, Y
The digital value of B is read, and the corresponding X ⁺ , X
^- , Xmax and Xmin are found from Table 1 (note that Table 1
Is only illustrated for the X-axis) and then saves those values for further comparison. The computer reads the values of XA, XB, YA and YB again in step F5. Conversely, if the status changes, Figure 1
The X mode determination procedure outlined in the dot line shown at 5 is performed. These are the four possible statuses (0,0), (1,0) for comparison with the previous status,
(1, 1) and (0, 1). The computer obtains the operation speed of the cursor positioning device by calculating the change time of each status. Currently, computer system clocks are generally in the range of 4 to 8 MHz. In practice, it has been found that the speed at which the user operates the grip-type control member of the cursor positioning device is lower than 5 KHz. Therefore, the computer can easily detect the operation speed of the cursor positioning device.

The computer determines the position of the cursor with reference to the pulse signal indicated by E in Table 1 and FIG. First, the computer assumes that the previous status is (0,0) in step F9. XA = 1, XB = 0
Indicates that the grip control member has been moved in the X ⁺ direction, and XA = 0, XB = 1 indicates that the grip control member has been moved in the X ⁻ direction; XA = 1, XB
If = 1, it indicates that the grip-type control member has reached either the maximum limit or the minimum limit depending on whether or not the X ⁺ flag is set. After these decisions, each flag status, X ⁺ , Xmin, Xmax, etc. is obtained,
These flag statuses are then held in predetermined registers for further determination of the control program.
Thus, in actual operation, the user simply moves the grip control to the upper left corner of the cursor positioning device to form a zero position, which then allows the device to generate the correct X and Y coordinate values. Occur.

FIG. 18 is a subprogram flowchart of the control program according to the present invention, and explains whether the cursor moves in the plus direction. On the other hand, FIG. 19 is a subprogram flowchart of the control program according to the present invention, which explains whether the cursor moves in the minus direction. The movement of the cursor movement on the computer display is proportional to the movement distance of the grip-type control member. The proportionality factor depends on the operating speed of the grip-type control member. The objectives of these procedures are as follows. 1. To limit the replacement of the grip type control member to 16 mm or less. However, cursor movement on the computer display is not affected by shortened replacement or different operating speeds of the grip-type control member. Thus, the present invention states that the cursor has already reached the corresponding margin on the computer screen even though the gripping control member of the known art has not yet reached the corresponding margin of the positioning device. No problem. 2. When the cursor on the display moves to an arbitrary position, it needs to be precisely moved around that position. 3. To match the movement speed of the cursor and the defined position with that of the grip-type control member to achieve smooth, fast and precise movement in operation. 4. Each axis, e.g., the X axis, has two registers for positive direction operation and two registers for negative direction operation. The recorded values of the plus and minus registers are interrelated, so that the gripped control member can return to its original position, and the cursor on the display can also return to its original position. Each symbol used in the control program flowchart is defined in Table 2 below.

VX represents the operating speed of the grip-type control member, which is at least two different operating speeds, for example V1, V
2. Switching between V3. Different proportional coefficients K are defined to correspond to different operating speeds. That is, the coefficient K
Is a constant whose movement of the cursor movement on the display is representative of the detected movement of the grip-type control member on the active area of the positioning device. For example, the coefficients K1 and K2 are, for example, (1,2), (1,3), (1,4), (2,4) or various other combinations, and the values of K1 and K2 are for the device driver program. Can be a default value, which is selected by the user. Therefore, at both the first speed level and the second speed level, the movements C1 and C2 can be determined with reference to Formula 1 and other formulas. In a preferred embodiment, C1, C2 may be non-performance variables due to the resolution of the computer display. As the resolution of the displays increases, the constant value K2 increases correspondingly, so that the cursor operates in the fine movement mode of operation, thus meeting the need for a minimum pixel movement of each display resolution. In such a case, K2 increases with increasing display resolution, and the minimum pixel movement decreases correspondingly. As a result, the movement of the cursor on the display is very smooth. X on display
Assuming an axial resolution of 640, the movement of the photoencoder is approximately 15.68 (ie, 196 × 0.08). 640 = (1 + C1) + (4cursor2), K1 =
1, K2 = 4 196 = C1 + C2 C2 = 148, C1 = 48 Assuming that the X-axis resolution of the display is 1024, it is as follows. 1024 = (1 + C1) + (7cursor2), K1
= 1, K2 = 7 196 = C1 + C2 C2 = 138, C1 = 58 As the display resolution increases from 640 to 1024, the pixel-to-pixel distance decreases. So,
K2 changes from 4 to 7, but does not affect the smooth movement of the cursor on the display. In the fine operation mode, the cursor can perform precise pixel-to-pixel movement at any resolution. Optical grid C3
Instead of reducing the illuminance and the distance between each grid in order to reduce the distance between them, the number of grids is reduced (in a known technique, 3
(Reduced from 20 to 200), the grip control can move only one grid, but the display cursor moves two or three grids. Therefore, if the grip-type control member is to be able to move from pixel to pixel within a range of less than 16 mm,
The above equations need to be used, and replacing the recorder and the constant K yields a cursor control that moves through an area of 10 mm x 8 mm. The device can also control any point on the display from the cursor. In this small operation cursor control device, C1 =
15, C2 = 27, and C3 = 113 (1 × 15−5x
27−10 × 113 = 1280). In such a design, the distance between the X-axis optical grids is (15 × 27
−113) x0.08 = 12 mm, and the distance between the optical grids on the Y axis is 1024/1280 = 12 = 10 mm
And thus the length of the gripping control member is 25 mm
It becomes suitable for thumb operation. FIG. 18 is a subprogram flowchart of the control program of the present invention, showing how the cursor moves in the plus direction. FIG. 19 is a subprogram flowchart of the control program of the present invention, showing how the cursor moves in the minus direction. FIG. 15 shows H1 and H2 respectively.
This is the part indicated as. When the grip type control member moves in the plus direction, the plus direction register V1X1 ⁺ reg
And the value stored in the V2X2 ⁺ reg increases. Correspondingly, the minus direction registers V1X1 ^- reg and V
The value stored in the 2X2 ^- reg is reduced by increasing the value of the plus register. When the X-axis coordinate is minimum, V1
The value stored in X1 ⁺ reg is 0, and V1X1 ^- r
The value stored in eg is equal to the value of C1, and V2X2
^{+ The} value stored in reg equals the value of C2 and V2
The value stored in X2 ^- reg is zero. The movement of the grip-type control member at the third speed is converted into temporary values V1X1 ⁺ and V2X2 ^{+ according} to Formulas 4 and 5 shown in Table 3 below. Thereafter, the temporary values are V1X1 ⁺ reg and V2X2 ⁺
reg, and then the value of the reference constant K3 is calculated using formula 2 in Table 3. After these procedures, the grip control will return to its original position and the cursor on the display will also return to its original position.

[Table 3] For example, K1 = 1, K2 = 4 K3 = (n-1) K2- (n-2) K1 = (3-1) 4- (3-2) 1 = 7 When the movement is equal to 1,
The movement of the cursor on the display indicates that it is equal to seven. The movement of the grip-type control member at the third speed level is determined by the registers V1X1 ⁺ reg and V2X2 ⁺ reg.
Are converted and stored using Formulas 4 and 5 in Table 3. ^{K3 x V3X3 + = K2 x V2X2} + + K1
x V1X1 V3X3 ⁺ = V2X2 ⁺ + V1X1 ⁺ 7x1 = 4xV2X2 ⁺ + V1X1 ⁺¹ = V2X2 ⁺ + V1X1 ⁺ V2X2 ⁺ = + 2, V1X1 ⁺ = -1 In this case, V2X2 ⁺ re is increased by V2X2 ^+.
Where the decreasing value of V1X1 ⁺ is 1. The result is the positive direction registers V2X2 ⁺ reg and V1X
The value stored in 1 ⁺ reg (ie, V2X2 ⁺ reg +
V1X1 ⁺ reg = 2 + (-1) = 1) indicates that it corresponds to the actual movement of the grip-type control member at the third speed level. Furthermore, Formula 3: (K1cursor1) + (K2cursor)
2) = Move display K1XV1X1 ⁺ reg + K2VV2X2 ⁺ reg
= Movement of display ie (1x-1) + (4x2) = 7 That is, when the grip type control member moves at the third speed level,
The same result is shown that the movement of the cursor on the display is equal to seven. The movement of the grip-type control member at the third speed level is converted to temporary values V2X2 ⁺ and V1X1 ⁺ using formulas 4 and 5 of Table 3, which are then converted to V2X
2 ⁺ reg and V1X1 ⁺ reg respectively.

Obviously, according to the present invention, the movement speed and position of the cursor on the display correspond to those of the grip-type control member, and the present invention allows smoother, faster, stable and precise movement. Will be implemented. The cursor positioning device of the present invention is provided with two plus registers and two minus registers. The value stored in the positive direction register and the value stored in the negative direction register are always correlated, so that the grip-type control member returns to the correct position and the cursor also returns to the correct position. it can.

It should be noted that the plus and minus registers on the X axis are interrelated. The definition of the positive register and the negative register on the X axis is for ease of understanding only, and two positive registers can be used to provide the same effect.

After the above-described procedure for determining the main program in the positive X-axis direction is completed, as a next procedure, it is determined in step F41 in FIG. 18 whether or not VX is equal to or lower than a predetermined reference speed. If yes, it indicates that the speed of the grip control member is below the low speed limit V1, ie, the first speed level. In step F42, the first
A determination is made whether the value stored in the speed level register V1X1 ⁺ reg is less than or equal to a constant C1. If no, the movement of the cursor is set to be proportional to the movement of the grip-type control member multiplied by a constant K1, then the value of V1X1 ⁺ reg is increased in step F43, and V1
The value of X1 ^- reg is decremented and the value is transferred to the computer. If the first speed level register V1X1 ⁺
If the value stored in reg is greater than or equal to the constant C1, it indicates that V1X1 ⁺ reg has reached its maximum value. In this case, the cursor movement is the constant K multiplied by the movement of the grip-type control member.
2 and then set to V in step F46.
The value of 2X2 ⁺ reg is increased, the value of V2X2 ^- reg is reduced, and the value is transferred to the computer. If the result of step F41 is no, it indicates that the grip-type control member is at the upper limit of the reference speed V1. Step F4
At 4, it is further determined whether VX is at the upper limit or the lower limit of the reference speed V2. When VX is at the lower limit of V2, step F45 is executed to determine whether the stored value of V2X2 ^- reg is the maximum value.
If yes, the movement of the cursor is set to be proportional to the movement of the gripping control member multiplied by a constant K1. If no, the movement of the cursor is set to be proportional to the movement of the gripping control member multiplied by a constant K2.

If there are only three speed levels in the cursor positioning device, the terminal signals A and B are combined. In this case, if the result of step F44 is NO, step F47 is executed and the plus register V2X
The left count stored in 2 ⁺ reg is read. If the value of K2xV2X2 ^- reg is smaller than K3,
The cursor movement is set to be proportional to the movement multiplied by a constant K2 of the grip-type control member, and then the procedure proceeds to step F46 where the cursor value exceeds the display margin when the operation speed of the cursor positioning device exceeds the reference speed V2. To prevent situations. This also prevents the problem of the cursor not returning to its original position. If step F
If the result of 47 is NO, step F48 is executed to determine whether V2X2 ⁺ reg is equal to or greater than the maximum value. If yes, the movement of the cursor is set to be proportional to the movement of the gripping control member multiplied by a constant K1, and if no, it is determined by register V2X2 ⁺ re.
g holds the left value, and the positive movement of the gripping control member at the third speed level is converted to register V1X1 ⁺ r.
eg and V2X2 ⁺ reg. Then, in step F49, it is determined whether or not the precise movement amount in the plus direction has exceeded half of the distance. If no, step F46 is executed to set the cursor movement to be proportional to the movement of the grip-type control member multiplied by a constant K2, and if yes, the procedure proceeds to step F50, where the value of V1X1 ⁺ reg Is reduced and V1X1 ^- re
the value of g is Masa, 2 is added to the value of V2X2 ⁺ reg, V1X1 ^- the value of reg is reduced, V2X2 ^- re
2 is subtracted from the value of g. With this procedure, when the grip-type control member is operated at the third speed level, the register V1X
1 ⁺ reg holds half the value of the constant C1. As a result, when the cursor moves to an arbitrary position on the display, there is always a precise movement around the position where the cursor is located.

The speed variable VX of the gripping control member shown in FIG. 18 has three speed levels: 0 <VX <= V1, V
1 <VX <= V2 and VX> V2. Alternatively, the speed variable VX can be divided into two speed levels, in which case the same excellent operation as in the case where the speed variable is divided into three is retained, and the procedure is almost compatible with most procedures in FIG. In the embodiment divided into two, if the answer to step F41 is NO, step F47 is executed, and step F4 is executed.
4 and step F45 are ignored. It is speed level V
This means that 1 and V2 are set to approximate or the same value. Thus, the second speed level is ignored when the grip control determines the value of VX. As shown in FIG. 14, the state of a cursor positioning device such as the key switch 13a can be detected by modifying the hardware. With such a design, the user simply clicks the switch to place the cursor positioner in the first position.
Operable at speed level. If the user clicks the switch again, the cursor positioner operates at the third speed level. At the third speed level, the cursor can be moved in the fast operation mode. Furthermore, the movement of the cursor is made in accordance with an increase in the speed of the grip-type control member on the cursor area, i.e., this increase in the speed of the grip-type control member is replaced by the speed of the grip-type control member.

FIG. 19 is a flowchart of a subprogram of the control program, which explains how the cursor moves in another direction. The flow is similar to FIG. 18 and also returns to the original position correctly.

FIG. 21 shows the speed detection procedure in the plus direction, which includes each speed detection subprogram. Terminals A and B correspond to terminals A and B in FIG.
Connect to If the result of step F44 is NO, the procedure proceeds to step F61 in FIG. If step F6
If the result of step 1 is yes, the procedure proceeds to step F in FIG.
Go to 47. Of particular note is that the positive speed VX uses the same control procedure at the third speed level, the fourth speed level and higher. In step F63, it is detected whether or not the cursor has exceeded the display margin. If yes, the speed is dropped to a lower level and it is again detected whether the cursor has exceeded the margin. Next step F64
Is executed only when the cursor does not exceed the margin. In step F64, the register V2X2 ⁺ re
A determination is made whether g is the maximum value. If yes, the procedure returns to step F43, if no, the procedure proceeds to step F65. In step F65, it is determined whether or not the value of the register V1X1 ⁺ reg is larger than half the value of C1. If no, the procedure goes to step F46. If yes, the procedure returns to step F66. At this time, the high speed value of the cursor, for example, the third speed level or higher, is converted into temporary values X2X2 ⁺ and V1X1 ⁺ , which are then stored in registers V2X2 ⁺ reg and V1X1 ⁺ reg.
Each is saved. As a result, the movement speed and positioning of the cursor on the display correspond to that of the grip-type control member, thereby achieving a smooth, fast, stable and precise movement.
