Abstract

PURPOSE:To eliminate the need for the selection of a cursor, by detecting the instructing timings of plural pointing devices, presuming an operation in which a time difference exceeds a constant time, as an individual point-out operation, and presuming the operation within the constant time as a combined operation. CONSTITUTION:For example, in case of turning a square corresponding to the operation of the pointing device, two pointing devices 104 and 105 point out two apexes of the square, and start to move, but when the system presumes display from the two pointing devices 104 and 105 as the combined operation, rotation is produced, and when it presumes the display as two individual operations, it is parallel displacement. Thereby, by providing a timing detection circuit which detects the point-out timings of two apexes, and presumes the operation as the individual operation when the time difference exceeds the constant time, and presumes the operation within the constant time as the combined operation, the operations of the two pointing devices can be controlled. In this way, it is not necessary to operate the cursor selection switch of the pointing device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an input device having a display device such as a CRT (cathode ray tube) or a liquid crystal display for displaying a single character, an image, etc. The present invention relates to an output device suitable for efficiently operating a cursor.

[Conventional technology]

The conventional device is a cRr that displays a single character and an image, as described in Japanese Patent Application Laid-Open No. 59-219782.
As a selection means for each of a plurality of cursors in a display device such as a cathode ray tube (cathode ray tube) or a liquid crystal display, a single pointing device is used as a means for selecting each of a plurality of cursors, and the pointing device is switched and used by a cursor selection switch. However, with this method, when multiple locations are specified on the screen, the user must remember which location was specified first.

Or, if the cursor is frequently switched, the cursor selection switch must be pressed each time, and this is effective in eliminating the hassle of having to memorize specified operation procedures. No consideration has been given to the tediousness of operating the cursor switch.

Furthermore, by moving multiple cursors at the same time, expressions regarding graphic conversion can be made more freely than when using a single cursor, and no consideration is given to the fact that command specifications on Sony can be omitted.

[Problem that the invention seeks to solve]

The above-mentioned prior art does not take into consideration the provision of multiple pointing devices as means for selecting multiple cursors indicating positions on the processing screen.

Since the single pointing device is constantly switched by a cursor selection switch, the operation is cumbersome and there is a problem in that multiple cursors in the housing cannot be moved or operated at the same time.

An object of the present invention is to provide multiple pointing devices for multiple cursors and eliminate the need for cursor selection, thereby eliminating the troublesome operations associated with cursor selection, particularly in graphic processing on a workstation.
The object is to easily rotate or enlarge one figure by picking up two points on an original figure such as a square or triangle with a cursor and moving them simultaneously.

[Means for solving problems]

The above object is to provide an input/output device equipped with a display device that displays a pig at a desired position based on a cursor specification, and to provide means for displaying a plurality of cursors on the display device, and for causing each of the plurality of cursors to be moved. A timing detection circuit that detects the instruction timing of multiple pointing devices and the plurality of pointing devices, and if the time difference exceeds a certain time, it is considered as an individual instruction operation, and if it is within a certain time, it is considered as a combination operation? This can be achieved by providing

[Effect]

The input/output device of the present invention enables multiple operations at the same time by providing multiple pointing devices.

In this case, it becomes necessary to determine whether simultaneous or very close temporal operations are operations that have meaning in combination, or whether they are separate operations. For example, when rotating a square according to the movement of a pointing device 2
Two pointing devices point to the two vertices of the square and start moving.If the system considers the display from the two pointing devices as a combined operation, rotation will be achieved, but if it considers them as two separate operations, then rotation will be achieved. , resulting in parallel movement. Therefore, the operation of the two pointing devices can be controlled by providing a timing detection circuit that detects the instruction timing of the two vertices, and if the time difference exceeds a certain time, it is regarded as an individual operation, and if it is within a certain time, it is regarded as a combined operation. do. Incidentally, the above-mentioned fixed time can be set externally according to individual differences. [Embodiment] An embodiment of the present invention will be described below with reference to FIG. 1.

In the input/output device shown in FIG. 1, in addition to the first pointing device 104, a second pointing device 105 is provided. The first pointing device operates the first cursor 102 on the display section 101, and the second cursor of the second pointing device 105 is operated. At this time, each cursor should have a different mark (color or shape) so that the two cursors do not get confused. FIG. 2(,) is an example of use in which the first cursor +02 is used for pointing a figure and the second cursor +03 is used for processing a menu screen. While modifying the circuit diagram with the first pointing device 104, if you want to refer to the circuit hidden under the menu screen, move the first cursor 1
The menu screen can be turned on and off using the second pointing device 107, which has previously determined the menu position, without moving the cursor or switching to the second cursor.

FIG. 2(h) is another usage example. This is an example of rotating a square on display section +01 using two cursors 102 and 103 without specifying a command.

However, in this case, each pointing device I
There are cases where each of the operations in Q4 and 105 has a meaning (
FIG. 2(c) is an example showing the meaning of the operation of only the first pointing device 104), so whether the operation is the first pointing device 104 alone or the first pointing device +04 and the second pointing device 105 It is necessary to distinguish whether this is due to a combination of

301 is a storage device that stores information to be displayed on a display device;
502 is an OR gate, and 305 is a display section. 304 is a counter register that stores the position (x, y coordinates) to be displayed; 15 is a first position generator that constitutes the first pointing device 104; and 306 is a register that stores the position to be displayed (x, y coordinates); The pointing device +04. j
When 05 is moved on a desk or the like, it emits a displacement signal (pulse) for the moved X,]'. 507 and 508 are counter registers that store the cursor position of each cursor 102 and 103; 309 and 110 are comparators that compare the contents of the counter register 504 and the counter registers 507 and 508; and 611 and 312 are AND The gate 313j14 is an OR gate of the cursor storage device 315.

Here, the storage information stored in the storage device 501 passes through the OR gate 502 and is constantly displayed on the display unit 305.

The stored contents of the counter register 504 change according to the scanning lines of the display section 303, and an address signal is input to the storage device 601.

Counter register 3076 or counter register 3
08 counts up or counts down based on the displacement signals from the displacement generators 305 and 506, and always stores the position of the cursor 102 or 105. The comparators 309 and 310 compare the currently displayed XY coordinates indicated by the counter register 304 with the contents of the counter register 307 or 308 that stores each cursor position, and only when they match, the AND gate 511 or 312 and allow the signals of the cursor storage devices 5A5 and 3111, which store the shapes of the cursors 102 and 103, to pass through. All of this signal passes through OR gate 515,
The OR gate 302 calculates the logical sum and displays it on the display section 303. As a result, the shape of the cursor 102 or 103 is displayed on the screen of the display unit 306.

〔Effect of the invention〕

According to the present invention, there is no need to operate the cursor selection switch of the pointing device, and there is an effect of simplifying the operation.

Also, as in the case of rotating one figure, multiple points can be specified and moved at the same time, which eliminates operations such as specifying rotation using commands on the menu screen. Since the movement of the figures is similar to that of the trap pointing device, it has the effect of making the operation intuitive.
