Abstract

PURPOSE:To limit the hand movements on a coordinate input area and to increase substantially a graphic input area or a menu area, by providing a selecting function to secure the correspondence between an input area on a coordinate input device and one of plural areas on a display screen. CONSTITUTION:A display screen is divided into two areas r1 and r2 and an input area R of a coordinate input means has a fixed size. A point P within the area R corresponds to the points p1 and p2 in both areas r1 and r2 of the display screen respectively and are displayed by different markers. An operator decides and selects either one of both points p1 and p2 while looking at the display screen. Thus, it is possible to supply a distant point with rather limited movements of hand on a coordinate input device. Furthermore, the input accuracy can be set by setting properly the size of the corresponding display area.

Description

[Detailed Description of the Invention] (Industrial Application Field) The invention relates to a coordinate input method and device, and a graphic processing device using a coordinate input device such as a tablet and a display device such as a C-T display. The present invention relates to a coordinate input method and apparatus for inputting commands.

(Prior art and its problems) In a graphic processing device that combines a coordinate input device such as a tablet, digitizer, or mask with a CRT display as a display device, hand movements on the coordinate input device can be performed using, for example, a stylus pen or kernel. From the coordinate point data obtained in accordance with I would select the given command menu and execute the contents.

In this type of conventional method and apparatus, the entire coordinate input area on the coordinate input device corresponds to the entire area on the display screen of the display device, and the points on the coordinate input area are input with the same precision everywhere, and The position on the coordinate input area was confirmed by displaying a marker on the display screen corresponding to the input coordinate position. Since the correspondence between the positions of the areas is fixed, the entire operation range on the coordinate input area and the moving range of the marker on the display screen always have a constant correspondence, which improves operability and display. It has the disadvantage that it is difficult to simultaneously satisfy visibility.

In other words, since the movement of the hand and the movement of the marker correspond in a fixed manner, the figure input area and the menu area, which use the input coordinate point data as they are, are placed in the same position on the input area of the coordinate input device. [If the graphic input area that requires high precision is widened, the menu area, which is not required in the first place, will become narrower, resulting in not being able to select as many items as possible, or vice versa. When trying to increase the menu area and lowering the stacking on the coordinate input area, there was a drawback that the necessary precision for the figure input area could not be obtained.0 Furthermore, coordinate point input for figure input and menu When command input processing is mixed, the graphic input area and menu area are assigned to different locations on the coordinate input area, so the range of movement of the operator's hand on the coordinate input area becomes wider. In addition, as another implementation example of this type of conventional method and apparatus, there is a method using a pop-up menu.

In order to solve the drawbacks of the above methods, when coordinate point data is input from the coordinate input device, a menu is temporarily displayed at the corresponding position on the display screen, and the menu area is displayed near the currently input point. This is a method that allows you to do this. However, in order to realize this system, a highly functional display and complicated software to control it were required.

(Objective of the Invention) The object of the present invention was made in consideration of these circumstances, and by associating the input area on the coordinate input device with a plurality of areas on the display screen, the hand on the coordinate input area can be adjusted. It is an object of the present invention to provide a coordinate input method and device that can improve operability by reducing movement and can substantially expand a graphic input area or a menu area.

(Structure of the Invention) According to the first invention, in a coordinate input method for inputting coordinate information to a graphic processing device equipped with a coordinate input device and a display device and generating a graphic processing command corresponding to the coordinate information, The coordinate input area on the input device is arbitrarily divided into a plurality of two-dimensional areas on the display area of the display device. Dimensional coordinate information is input, and each time coordinate information is input, it is calculated which position within each two-arrow area on the display screen the input coordinate information corresponds to, and the position on the calculated display screen is calculated. By simultaneously displaying markers at corresponding positions, and specifying the area on the display screen to which the coordinate information input from the coordinate input device should correspond, by inputting the coordinate information, the marker can be displayed within the specified area. There is obtained a coordinate input method characterized in that a graphic processing command associated with the calculated position of is selected and inputted to a graphic processing device while referring to the position of the marker.

Furthermore, according to the invention of 1 wooden tablet 2, there is a coordinate input means for inputting two-dimensional coordinate information, and a position coordinate indicating the range of a two-dimensional area obtained by arbitrarily dividing the display screen area of the display means in response to an area setting start signal. an area storage circuit for storing data; a graphic processing command storage circuit for receiving function setting signals and storing graphic processing commands corresponding to each area set in the area storage circuit; and the coordinate input. a display coordinate calculation circuit that converts coordinate data output from the means into display coordinates of each point in a plurality of areas on a display device using the contents in the area storage circuit; and an output signal of the display coordinate calculation circuit. a display section that receives the coordinates and displays them as markers on a plurality of display areas of a display device; a graphic processing command selection circuit that determines which graphic processing command trap corresponds to the coordinate information obtained by the input means; and a graphic processing command selection circuit that determines which graphic processing command trap corresponds to the coordinate information obtained by the input means; It is characterized by including a graphic processing command execution circuit that selects and executes a graphic processing command set in a storage circuit, and a control circuit that controls the operation of each of the circuits and the transmission and reception of signals between each circuit. A coordinate input device is obtained.

(Principle of the invention) The present invention will be described in detail below with reference to the drawings.

In the coordinate input method of the present invention, as shown in FIG. 2(a), for the coordinate input area in the coordinate input means.

As shown in FIG. 1(b), a correspondence relationship is given to each of a plurality of areas on the display screen that are displayed correspondingly.

For the sake of explanation, an example will be given in which the display screen is divided into two areas. For one area R on the coordinate input area shown in FIG. 1(a), this area is displayed on the display screen 2
The ranges of the two regions rl and r2 and graphic processing commands to be assigned to the regions rl and r2 are set and stored in advance. Now, when inputting the coordinates of point P in region R from the coordinate input device,
The input coordinate position is converted into the coordinate value pi on the display screen based on the correspondence between the area R and rl, and
By converting the input coordinate position into the coordinate X@p2 on the display screen based on the correspondence relationship with Informs you of possible graphics processing instructions. At this time, whether the operator executes a graphic processing command corresponding to point p1 in region rl or a graphic processing command corresponding to point p2 in region r2, that is, whether the currently input coordinate point data is Perform the operation to select which area it belongs to,
Execute a graphic processing instruction corresponding to any point.

One example of an operation method for selecting an area is to provide a coordinate input device with an area selection function.A specific example of this method is to use a selection button on the stylus pen of a tablet, which is an example of a coordinate input device. There are methods to use the function selection buttons normally provided on the mouse. As another example of the operation method for selecting an area, it is possible to determine which coordinate point data is currently being input based on the history of a series of operation procedures in graphic processing work performed by the coordinate input method of the present invention. Alternatively, a method may be adopted in which software determines whether the object belongs to this area.

Here, the effect of making the region correspond to the two regions rl and rl will be explained using FIG. 3.

Figure 3 (→ shows a coordinate input method used in a conventional graphic processing device. As shown in Figure 3 (a), the coordinate input area is divided into two areas, R1 and l'L2. , two areas rl and rl are displayed correspondingly on the display screen.At this time, without looking at the display screen, point pi
When trying to input and execute graphic processing commands corresponding to two points PI and P2 on the coordinate input area,
It is necessary to specify the location. Therefore, in a graphic processing device that uses the coordinate input method as shown in FIG. When processing graphic data by selecting from a menu, select point PI on coordinate input means 1 and R2.
, P2, and so on, which increases the burden on the nine operators who must frequently specify two distant points on W4.

In Itto Figure 3 tb), one point P in the coordinate input area is displayed as two different markers at two points p3 and p4 on the display screen. While looking at the display screen, the operator selects the function corresponding to the point P currently being input by selecting the point P on the display screen.
3. Decide which of the functions indicated at point p4 should be selected.

All you have to do is input the point of the sword that corresponds to the desired function. At this time, on the coordinate input area, 1 point P corresponds to 2 points p3% p4, which improves the display image, so the operator does not need to move his hand to specify another point on area R. All you have to do is select the multi-functionality according to the nine methods mentioned above in the same place.

For the reason explained in FIG. 3, if you want to input highly accurate coordinate information as graphic data, you can input the entire coordinate input area for the area on the display screen independently of the Meniere area using a coordinate input method for inputting graphic data. It can be used as Conversely, if you want to set a large number of graphic processing commands that can be selected within an area rather than focusing on precision, or in other words, if you want to allocate various graphic processing commands as multiple menu items on the coordinate input means, you can also input graphic data. A menu can be assigned to the entire input area on the coordinate input device without reducing the area.
