Abstract

PURPOSE:To improve the operability in a conversation type editing system by making the accuracy of pointing variable when the entire pattern is an object of pointing and when a region is selected as an object of pointing. CONSTITUTION:A region 23 of a pointing device 12 using a graphic tablet is a system region commanding to change the accuracy of pointing. The accuracy 1 taking the entire pattern as an object of pointing and the accuracy 2 taking one of the displayed window as an object of pointing are prepared as to the accuracy of pointing, and the state of the accuracies 1, 2 is repeated alternately by designation. The designation is executed by picking up the region 23 of the tablet 22. In picking up the region 23, the state of accuracy at that point of time is discriminated and when the state is in the accuracy 2, the state restores to the accuracy 1, the state designates newly a window region from the accuracy 1 and then the accuracy is matched to the window, and the state reaches the accuracy 2.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a system for creating and collecting figures in an interactive manner, and is particularly suitable for inputting coordinate values or instructing data using a pointing device. The present invention relates to a coordinate input device having an operation procedure and a control method.

[Background of the invention]

2. Description of the Related Art In systems for creating and editing figures, a pointing device is used to input a position on a screen of a display device. Conventionally, in this input, the pointing input range covers the entire screen, so it was difficult to input 1I11 kana points.0There is also a method of enlarging a part of the screen and inputting fine points, but it is difficult to input small points while looking at the whole screen. The drawback was that data could not be entered.

(In systems using pointing devices, there is a workstation, information processing, VOL.

25, 1984. It is described in k2 etc. )
[Object of the Invention] An object of the present invention is to accurately obtain positional information necessary for editing graphic data by using a pointing device and a display device.
An object of the present invention is to provide a coordinate input device that improves the operability of an interactive gK collection system by providing a means for easily inputting information.

[Summary of the invention]

When using a pointing device as a means of inputting coordinate values, the pointing device uses the entire screen of the display device for input, so the amount of movement of the pointing device and the amount of movement of the marker representing the pointing device are necessary for the operation of the pointing device. It is determined by the size of the space and the size of the screen. However, if the operating space of the pointing device is too large, the operability will be poor, and if it is small, it will be inconvenient when pointing to a part of the screen.

When an area is created on one screen, such as in a multi-window system, and editing operations are performed within that area, the pointing range only needs to be within that area.

The present invention attempts to facilitate coordinate input operations by making pointing accuracy variable when the entire screen is the object of pointing and when a certain area is the object of pointing.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

FIG. 1 is a hardware configuration diagram showing an embodiment of the present invention. In FIG. 1, numeral 11 denotes a display device for displaying data, which can display a plurality of areas simultaneously using a multi-window system. 12 is a display device 11
It is a pointing device that indicates the coordinates on the screen of
In this embodiment, a graphic tablet is used. 13
is a processor that controls each device, and operates according to a program stored in the program memory 14.

Reference numeral 15 is a storage device for storing data and information regarding areas to be displayed on the display device 11, and reference numeral 16 is a register for storing work data.

Figure 2 shows an overview of the graphic tablet.
In the figure, 21 is a pen for indicating the position;
22 is a tablet. The tablet 22 is divided into three areas 23, 24, and 25, 23 is a system area for instructing to change the pointing precision;
5 is a data area for indicating a position on the screen, and 24 is a protection area for preventing erroneous input between the system area 24 and the data area 25.

Figure 3 shows the operating procedure for making the pointing accuracy variable, which is the object of the present invention. window (area)
Prepare precision 2 with one of the objects as the pointing target,
It is assumed that the states of precision 1 and precision 2 are alternately repeated as specified. Designation of accuracy change is performed by picking the system area 23 of the tablet 22.

In Figure 3, when you pick the system area 23 (3
1) Determine the state of accuracy at the time of picking ゛(
32), if the state is precision 2, return to precision 1 (33), and if the state is precision 1, specify a new window (area) 34
), after that the accuracy will match that window (area) and the state will become accuracy 2 (35). Figure 4 shows the relationship between the screen and tablet at accuracy 1, and Figure 5 shows the relationship between the screen and tablet at accuracy 2. 4 and 5, 41 is the screen of the display device, 42 is the tablet, 43.44
indicates a window (area) displayed on the screen 41, and 45 indicates the pointing position.

FIG. 6 is a flowchart showing an example of a coordinate input program stored in the program memory 14 to realize the present invention. The coordinates on the screen in the 0 line method are: (Locus II) = (Position ff1) X (Position) in equation 0, which is determined by (ratio) + (correction value), is the position of Ben 21 on tablet 22. (Ratio) and (Correction value) differ depending on the precision. When precision is 1, (Ratio) is the ratio between the screen size and the size of the tablet 22, and (Correction value) may be 0. At the time, (ratio) is the ratio between the size of the specified window (area) and the size of the tablet 22, and (correction value) is the position of the window (area) on the screen.

In FIG. 6, when the input position from the tablet 22 is in the data area 25, the coordinates on the screen are calculated (69), and when the input position is in the system area 23, the accuracy is changed (63 to 68). In the change process, when the accuracy status is accuracy 2, calculate (ratio) and (correction value) for the screen and change the status to accuracy 1 (64.65); conversely, when the accuracy status is accuracy 1, is the specified window (area)
The (ratio) and (correction value) for each are determined and the state is set to precision 2 (66 to 68), and both (ratio) are determined.

(correction value) and status are stored in the register 16. It is also assumed that information regarding the size of the window (area) and the display device is stored in the display data memory 15.

The present invention can be implemented through the embodiments described above.

〔Effect of the invention〕

According to the present invention, by making the precision of the pointing device variable without changing the display state of the display device, inputting detailed coordinate point data and moving the rough pointing position can be performed within the same operating range. , can be done while looking at the same screen, which has the effect of making the operation procedure for inputting coordinates accurate and easy.
