DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for switching between a computer to be controlled and a terminal to be controlled when a plurality of computers and terminals are used at the same time. The present invention relates to an apparatus for switching a target computer and a control target terminal.

[0002]

2. Description of the Related Art Recently, with the spread of computers, one user can simultaneously operate a plurality of computers and terminals (a terminal is one of the computers in this specification, a host computer, a terminal connected to a network, Computers, including stand-alone computers that perform processing).

FIG. 6 shows a conventional work environment in which one person uses a plurality of computers at the same time. As shown in FIG. 6, conventionally, a plurality of computers 22a, 22b, and 22c are arranged on one desk 21, and a user sits at a place not far from any of the computers. In the foreground, input means and pointing devices of the respective computers, for example, keyboards 22a ', 22b', 22c 'and mice 22a ", 22b", 22c "are arranged.

In use, a user faces a computer to be operated, operates a keyboard and a pointing device of the computer, and gives various instructions to the computer to perform various processes.

[0005] However, in the working environment as described above, there are a plurality of sets of keyboards and mice, and a large desk surface is required to arrange them.

Further, when switching the computer to be operated, the user must turn to the computer to be operated, replace the keyboard and the like, and draw the keyboard and the like to be operated.
For this reason, the work was interrupted and the work efficiency was not improved in some cases.

On the other hand, in order to operate a plurality of computers with a single keyboard, mouse, etc., a computer to be controlled is placed between a single set of input means or a pointing device and the plurality of computers. A switching control device for a computer to be controlled having a switch for switching has also been proposed.

FIG. 7 shows the computer switching controller 23.
The work environment when using is shown.

As apparent from FIG. 7, according to the computer switching control device 23, a single keyboard 24 and a single mouse 25 are used to control a plurality of computers 22a, 22a.
22b and 22c can be operated. For this reason, a small work space is required, and the user does not need to rearrange input means such as a keyboard when changing the computer to be controlled, thereby improving work efficiency. .

[0010]

However, the above-mentioned conventional computer switching control device cannot be said to provide a work environment adapted to the physiological and psychological characteristics of humans in relation to humans and machines. .

That is, since the computer switching control device is a device independent of a keyboard and a mouse, when the computer to be controlled is to be switched,
The user had to reach for a computer switching control device located away from the normal range of key operations (the area within reach of the keyboard and mouse) and depress one of the switching switches.

In this operation, it is necessary to confirm the location of the computer switching control device, release the hand from the keyboard, mouse, etc., and depress the corresponding switch.
In many cases, the user's viewpoint was moved away from the screen, and thinking for work was interrupted.

Further, in the conventional switching by the computer switching control device, the position of the mouse cursor on each computer screen is configured so that the position at the time of last use is stored. The user has to find the mouse cursor on the computer screen after switching.

However, ergonomically preferable movement of the mouse cursor is as follows. When control is switched from one computer screen to an adjacent computer screen, the mouse cursor moves from an unspecified position on the computer screen before switching to another computer screen after switching. Move to a close position (for example, an adjacent side) on the computer screen, jump over the physical frame of the computer, and display the mouse screen so that the mouse cursor moves from the computer screen before switching to the computer screen after switching. Is desirable.

In other words, when the mouse cursor is moved by switching between a plurality of computers arranged adjacent to each other, it is as if the mouse cursor continuously moves on a plurality of adjacent computer screens one after another. It is preferable to move as follows.

According to the movement of the mouse cursor as described above, the user can track the mouse cursor by moving the viewpoint continuously on a plurality of computer screens.

On the other hand, in the switching of the control target by the above-described conventional computer switching control device, the user moves the mouse cursor to an unspecified position on the computer screen after the switching, so that the user can use the mouse cursor on the computer screen after the switching. The mouse cursor had to be found and continuous viewpoint movement could not be performed. In this regard, the prior art has room for improvement.

Therefore, an object of the present invention is to solve the problem in a work environment using a plurality of computers.
It is an object of the present invention to provide a computer switching control device that can switch a computer to be controlled by operating one pointing device, and that allows the cursor movement of the pointing device to follow a natural viewpoint.

[0023]

Next, claims 3 and 4 of the present application will be described.
The embodiment will be described below with reference to the accompanying drawings. As will be described later, the computer switching control device according to claim 3 switches the computer to be controlled according to the moving speed or acceleration of the cursor of the pointing device, whereas the computer switching control device according to claim 4 Switches the computer to be controlled according to the amount of movement of the cursor of the pointing device.

First, an embodiment of a computer switching control device according to claim 3 of the present invention will be described. FIG. 1 shows an arrangement of a computer, input means and a pointing device when the computer switching control device according to claim 3 of the present application is used.

As shown in FIG. 1, when using the computer switching control device according to the present invention, a plurality of computers 2a, 2b, 2c to be used are arranged on a desk 1, and these computers 2a, 2b, 2c are connected to each other. The keyboard 3 and the mouse 4 are arranged between the users. These keyboards 3
And the mouse 4 are connected to the computer switching control device 5,
The cable is branched from the computer switching control device 5 and connected to the computers 2a, 2b, 2c.

Next, a description will be given of a configuration for making the computer switching control function in the plural computer system having the plural computers. FIG.
FIG. 3 is a diagram illustrating a configuration necessary for causing the computer switching control to function in the multiple computer system of FIG.

As shown in FIG. 2, the computer changeover control device 5 comprises a computer changeover switch 6 and a changeover control section 7.
And

On the other hand, a pointing device (mouse 4
) Is the X that generates the X-axis component data of the movement amount.
An axis data generator 9 and a Y-axis data generator 10 for generating Y-axis component data of the movement amount are provided. Here, the X-axis direction refers to a horizontal direction on the screen of the computer 2a, 2b, 2c, and the Y-axis direction refers to the computer 2
The directions perpendicular to the screens a, 2b, and 2c.

FIG. 2 shows the X, Y of the movement amount of the mouse 4.
4 shows a configuration for generating axis component data. The mouse 4 has a ball 11 that rolls as it moves. The mouse 4 contacts two rotatable X-direction movement amount detection rods 12 and Y-direction movement amount detection rods 13 that are orthogonal to each other. Have.

When the user moves the mouse 4, the ball 11 rolls in contact with a desk surface or the like, and the rotation of the ball 11 is detected by the X, Y direction movement amount detection rods 12, 13 as the number of rotations. Based on the rotation speeds of the X and Y direction movement amount detection rods 12 and 13, the X and Y axis data generation units 9 and 10
The movement amount in the direction and the Y direction is calculated.

With the above configuration, the moving amount and moving direction of the mouse 4 can be grasped. Although a mouse has been described in the above example, pointing devices such as a trackball, a slide pad, and a pressure-sensitive pointing button also have the same X, Y-axis data generation unit 10, and will be described as being included in the present embodiment.

The keyboard 3 is connected to the input unit 2 of each of the computers 2a, 2b, 2c via the computer changeover switch 6.
a ', 2b', and 2c '. The number of computers is not limited to three, and more computers can be connected. In FIG. 2, the connectable computer input unit 8 is shown by a virtual line to indicate this.

The input from the keyboard 3 is sent to the computer input units 2a ', 2b', 2c 'selected by the computer changeover switch 6. Switching of the computer changeover switch 6 is controlled by a changeover control unit 7. Further, the switching of the switching control unit 7 is activated by the movement of the pointing device.

A process for the switching control unit 7 to perform the switching operation by the movement of the pointing device will be described below. FIG. 3 shows a processing flow in the switching control unit 7. Note that this processing flow shows processing in a case where three computers are switched according to the moving speed of the mouse 4 in the X direction. In the case where the computer to be controlled is switched based on the acceleration, in the following description, "speed" can be replaced with "acceleration", so that the description will not be repeated.

Here, a variable indicating each computer is N
(N = 1 to 3). Also, the three computers
In the + direction of the X axis (to the right for the user), N =
It is assumed that they are arranged in the order of 1, 2, and 3.

As shown in FIG. 3, in the switching control according to the present embodiment, first, the switching control unit 7 inputs the amount of X-axis movement of the mouse 4 from the X-axis data generation unit 9 of the mouse 4 (step 100). . The variable M (arbitrary) indicating the control target computer at the time of inputting the X-axis movement amount is substituted for the variable N indicating the current control target computer.

Upon input of the X-axis movement amount of the mouse 4, the switching control unit 7 sets the speed or acceleration of the mouse 4 in the X-axis direction within a predetermined time T in a positive or negative direction. It is determined whether the threshold value is exceeded (step 11).
0).

As a result, when the speed or acceleration of the mouse 4 in the X-axis direction does not exceed the predetermined threshold value, that is, when the mouse 4 moves within the normal speed or acceleration range, the switching control unit 7 The amount of movement of the mouse 4 is transmitted to the control target computer N without switching the target computer (step 120).

When the speed or acceleration of the mouse 4 in the X-axis direction is +
If the threshold value is exceeded in the direction, it is determined whether the control target computer N is smaller than 3 (N <3) (step 130). This is when the currently controlling computer is the rightmost computer (N =
3) is for detecting this because the control cannot be switched to the right computer any more.

As a result of the determination in step 130, if N indicating the current control target computer is smaller than 3 (N <3), a sufficient amount of movement of the mouse cursor until reaching the right end of the computer screen is determined. N (step 135).

Subsequently, the value of N + 1 is substituted for a variable N indicating the computer to be controlled (step 140).

The variable N of this new controlled computer
Is sent to the computer changeover switch 6, and the computer to be controlled is switched to the computer indicated by the variable N (step 150). That is, the control is transferred to the computer to the right of the computer to be controlled up to that point.

Here, on the computer screen out of the control object, the final X coordinate of the mouse cursor is located on the right side of the screen by the processing in step 135. This is because when the control returns to the computer, This is because the mouse cursor starts moving from the right side of the screen when the control returns to the original computer screen by a general process of returning the mouse cursor to the position immediately before the control is released. As a result, it is possible to make the mouse cursor appear to move between screens.

On the other hand, if N indicating the current computer to be controlled is not smaller than 3, that is, if N = 3, the current computer to be controlled is the rightmost computer. Is performed, the movement amount of the mouse 4 is transmitted to the current computer N to be controlled (step 120).

That is, when the current computer to be controlled is located at the rightmost end of the plurality of computers, the computer to be controlled does not switch even if the pointing device is quickly swung rightward.

Next, when it is determined in step 110 that the X-axis moving speed of the mouse 4 has exceeded a predetermined value in the negative direction, the control target computer N is larger than 1 (N> 1).
It is determined whether or not it is (Step 160).

This is because if the currently controlled computer is located at the leftmost position of a plurality of computers, control cannot be switched to the leftmost computer, and this is detected.

As a result of the above determination, if N indicating the current computer to be controlled is greater than 1 (N> 1), the amount of movement of the mouse cursor sufficient to reach the left side of the computer screen in the negative direction of the X axis. To the current controlled computer N
(Step 165). This is step 13
As in the case of No. 5, when the control is switched from the left computer to the original computer, the mouse cursor appears to move continuously between the computer screens.

After the processing in step 165, the value of N-1 is substituted for a variable N indicating the computer to be controlled (step 170).

The variable N of the new computer to be controlled is sent to the computer changeover switch 6, and the computer to be controlled is switched to the computer indicated by the variable N (step 150). As a result, the control is transferred to the computer on the left side of the control target computer.

On the other hand, if N indicating the current computer to be controlled is not greater than 1, that is, if N = 1, the current computer to be controlled is the leftmost computer, and the computer to be controlled is switched. Is not performed, and the mouse 4
Is transmitted (step 120).

The above is the configuration and processing of the computer switching control device according to the third embodiment of the present invention. Next, the operation and effect of switching the control target computer by the computer switching control device 5 will be described.

FIG. 4 shows three computers 2a, 2b,
2c are arranged from the left in this order, and the mouse operation, the switching of the control target computer, and the mouse cursor on the computer screen when the control is successively transferred to the computer on the right by the operation of the mouse are shown in association with each other. It is.

In the upper part of FIG. 4, the computers 2a, 2b, 2
3C shows a screen, and the mouse cursor 14 is shown on each computer screen. In the lower part of the screen of the computers 2a, 2b and 2c, a graph showing the change over time of the movement of the mouse with time on the horizontal axis and speed on the vertical axis is shown.

Although the moving speed of the mouse actually has a slope at the time of acceleration, here, for easy understanding,
It is assumed that the moving speed changes stepwise in a discontinuous manner.

On the speed axis of the graph of the temporal change of the mouse movement, predetermined threshold values are set in the + direction and the-direction, respectively. The movement of the mouse exceeding the threshold value of the speed serves as a trigger for switching the computer to be controlled (operation for operating the switch).

As shown in FIG. 4, initially, the mouse cursor 14 is within the screen of the computer 2a. Until time T0, the user is moving at a speed less than or equal to the threshold, so that the control target computer 2a is not switched. During this time, the mouse cursor 14 moves within the screen of the computer 2a according to the movement of the mouse.

Around time T0, the user operates the computer 2b.
Suppose that the user feels the need to switch the control target. At this time, the user only has to shake the mouse strongly to the right and operate the mouse so that the moving speed in the + direction exceeds the threshold.

By this operation, the mouse cursor 14 is moved to the right side of the screen of the computer 2a by the processing of the switching control unit 7 already described, and the computer to be controlled is
It is switched from a to 2b. (See steps 135 and 140 in FIG. 3) In response, the mouse cursor 14
Shifts from the screen of the computer 2a to the screen of the computer 2b on the right. The starting position of the mouse cursor on the screen of the computer 2b is located at the final position during the previous control, that is, on the left side of the screen of the computer 2b (see the processing of step 165 in FIG. 3).

Similarly, it is assumed that the user feels the need to switch the control target from the computer 2b to the computer 2c around time T1. If the user similarly shakes the mouse to the right in the same manner, the computer to be controlled moves to the computer 2c on the right, and the mouse cursor 14 appears on the left side of the screen of the computer 2c.

When the control object is switched to the computer to the left, the mouse may be operated in the negative direction of the X axis, which is opposite to the above.

As can be seen from the above description, according to the computer switching control device of the present invention, when the user wants to shift the control object to the computer on the right with respect to the computers arranged on the left and right, the user moves the mouse. If you want to move the control target to the computer on the left side by vigorously swinging to the right, you can shake the mouse strongly to the left. This operation
It is possible to provide an operation feeling that is very natural for humans.

On the computer screen in the direction in which the mouse is swung, since the mouse cursor is located on the side near the computer before the control is switched, the user can easily follow the mouse cursor by continuously moving the viewpoint. You can do it. This is also a natural operation for the user.

Moreover, the user does not need to release his hand from within the reach of normal computer operation when switching the computer to be controlled. For example, when the mouse is operated and the mouse is moved as it is, the computer to be controlled can be switched.

That is, according to the computer switching control device of the present invention, the computer to be controlled can be switched with an operation feeling that is very natural for the user, and work thinking is not interrupted by the switching of the control object. is there.

Next, a computer switching control device according to claim 4 of the present application will be described.

The computer switching control device according to the fourth aspect of the present invention is different from the computer switching control device according to the third aspect only in that the moving amount of the mouse cursor within a predetermined time triggers the switching of the computer control. .

Therefore, the arrangement of a plurality of computer systems using this computer switching control device (FIG. 1)
The duplicated description of the hardware configuration (FIG. 2) that functions to switch the computer control is omitted. Further, the point that the mouse cursor continuously moves between the computer screens by operating the mouse is apparent from FIG. 4 and the description thereof, and the description thereof is also omitted.

Therefore, the control switching method of the computer switching control device according to claim 4 will be described below with reference to FIG.

In the switching control of the computer according to the present embodiment, as shown in FIG. 5, an X-axis movement amount is first input (step 200). The variable M (arbitrary) indicating the control target computer at the time of inputting the X-axis movement amount is substituted for the variable N indicating the current control target computer.

Next, when the X-axis movement amount of the mouse cursor is input, it is determined whether or not the X-axis movement amount of the mouse cursor exceeds a predetermined threshold value in the + or-direction within a predetermined time T. Is determined (step 210). Here, the threshold value of the amount of movement within the predetermined time T is different from the speed, and is usually, for example, 1.5 times, 2 times, or 3 times the horizontal length of the computer screen. This means a case where the amount of movement that does not move by the operation of (1) moves within a certain time.

When the threshold value of the amount of movement of the mouse cursor is not exceeded within the predetermined time T, that is, when the mouse cursor moves on the computer screen as in a normal operation, the control target computer is not switched. The amount of movement of the mouse cursor is transmitted to the control target computer N as it is (step 220).

If the amount of movement of the mouse cursor in the X-axis direction exceeds the threshold value in the + direction, it is determined whether or not the control target computer N is smaller than 3 (N <3) (step 230). This is when the computer currently controlled is the rightmost computer (N = 3).
Is to detect this because control cannot be switched to the computer on the right any longer.

As a result of the determination in step 230, N +
The value of 1 is substituted for a variable N indicating the computer to be controlled (step 140).

Here, as shown in FIG. 3, the reason why a sufficient amount of movement of the mouse cursor until reaching the right end of the computer screen is not transmitted to the control target computer N is that
If a sufficient threshold value is set in advance, the mouse cursor always reaches the right edge of the computer screen so that the amount of mouse cursor movement reaches the above threshold value. This is because there is no need to add an amount.

That is, according to the present embodiment, for example, if the mouse cursor is moved rightward by a distance larger than the normal operation range, the mouse cursor reaches the right end of the computer screen, and then the right computer controls the computer. Is switched. Thus, since the final position of the mouse cursor is on the right side of the computer screen, when control returns to the computer, the mouse cursor can start from the right side of the computer screen.

The variable N of the new computer to be controlled updated in step 270 is sent to the computer changeover switch, and the variable N
(Step 25)
0). That is, control is transferred to the computer to the right of the control target computer up to that point.

On the other hand, if N indicating the current computer to be controlled is not smaller than 3, that is, if N = 3, the current computer to be controlled is the rightmost computer. Is performed, the moving amount of the mouse cursor is transmitted to the current computer N to be controlled (step 220).

Next, if it is determined in step 210 that the amount of movement of the mouse cursor has exceeded a predetermined value in the negative direction of the X-axis, the control target computer N is larger than 1 (N
> 1) is determined (step 260).

This is because if the currently controlled computer is located at the leftmost end of a plurality of computers, control cannot be switched to the leftmost computer, and this is detected.

As a result of the above determination, if N indicating the current computer to be controlled is greater than 1 (N> 1), the value of N-1 is substituted for a variable N indicating the computer to be controlled (step 270).

Here, it is not necessary to transmit the movement amount of the mouse cursor until reaching the left end of the screen of the currently controlled computer to the currently controlled computer, as described above.

The variable N of the new computer to be controlled is sent to the computer changeover switch, and the computer to be controlled is switched to the computer indicated by the updated variable N (step 250). As a result, the control is transferred to the computer on the left side of the control target computer.

On the other hand, if N indicating the current computer to be controlled is not greater than 1, that is, if N = 1, the current computer to be controlled is the leftmost computer. Is performed, the movement amount of the mouse cursor is transmitted to the current computer N to be controlled (step 220).

According to the computer switching control device of the fourth aspect, unlike the computer switching control device of the third aspect, even if the final position of the mouse cursor is not given according to the switching of the control, it is automatically performed. Since the mouse cursor is located on the side of the computer screen in the moving direction, the processing is simple and high reliability can be obtained.

The description of the embodiments of the computer switching control device according to claims 3 and 4 of the present application is completed above. A modified example of the present invention will be described next. The computer switching control device of the present invention is only required to be switched by operating the pointing device and to be able to easily find the cursor of the pointing device on the computer screen after the control switching. For this reason, there may be various modifications of the above-described embodiment.

First, in the above-described embodiment, the switching control unit 7 is provided in the computer switching control device 5, but the computer switching control device of the present invention is not limited to this, and a pointing device ( The mouse 4) may be used. In this case, the computer switching control device 5 can have a simple structure including only the computer switching switch 6.

Next, in the above-described embodiment, the moving speed and the moving amount of the pointing device in the X-axis direction are used as triggers for control switching of the computer. However, the computer switching control device of the present invention is not limited to this. The acceleration of the control or input of a switch specially provided on a mouse or the like can be used as a trigger for control switching of the computer.

If the computer to be controlled can be switched according to the moving speed of the pointing device cursor in any direction, not limited to the X-axis direction, the computers arranged vertically, horizontally, and vertically or horizontally on the same screen can be divided. This is convenient for switching control of a plurality of computer screens.

When acceleration is used as a trigger for switching the computer to be controlled, a mechanical acceleration detection mechanism can be incorporated.

When the switch dedicated to control switching is provided on the pointing device, the same operation and effect as those described in the above embodiment can be obtained.

Next, in the above embodiment, the cursor (mouse cursor 14) of the pointing device on the computer screen before switching is moved to a position near the computer screen after switching. The device is not limited to this, and it is sufficient that the user can easily confirm the cursor after the switching by some method.

For example, the pointing device cursor can be positioned at a certain position on the computer screen after the control target is switched. Further, for example, the shape, size, and color of the cursor of the pointing device immediately after the control switching may be changed so that the user can find the cursor quickly.

Finally, in the description of the embodiment of the computer switching control device according to the fourth aspect, the threshold value of the amount of movement of the mouse car is fixed, but this threshold value can be changed as appropriate. In addition, a computer switching control device may be configured.

[0095]

As is apparent from the above description, according to the "computer switching control device" of the present invention, a single input means (keyboard), a single pointing device, and a plurality of computers are connected. The computer to be controlled can be switched by operating the pointing device.

Thus, unlike the conventional work environment using a plurality of computers, a large work space is not required, and there is no need to replace a keyboard or the like when changing the computer to be controlled.

Further, unlike the conventional computer switching control device, it is not necessary to release the hand from the normal key operation range and depress the switching switch at a remote place. Thus, the work of the user is less likely to be interrupted.

Further, according to the computer switching control device of the present invention, if the moving direction, the moving speed, the acceleration, and the like of the pointing device cursor are arranged in correspondence with the detection direction and the position of the computer, the cursor of the pointing device can be moved. By the movement, the control target can be moved to a computer on an extension of the moving direction of the cursor.

Further, since the pointing device cursor is located on the side near the computer before control switching on the computer screen after switching the control target, the pointing device cursor shifts one after another on a plurality of computer screens adjacently arranged. Can be felt by the user.

That is, according to the computer switching control apparatus of the present invention, by appropriately arranging a plurality of computers, the user can move the pointing device cursor in accordance with the arrangement direction of the actual computers, for example, instantaneously and quickly. Then, the control target can be moved to the computer on the movement direction line of the pointing device cursor, and the cursor after control switching can be tracked by continuous movement of the viewpoint.

This work environment matches well with natural human movements and does not interrupt the work, so that the efficiency of information processing by operating a plurality of computers can be greatly improved. You can.
