Abstract

PURPOSE:To eliminate the necessity of operation for moving a screen and to improve operability by automatically moving coordinates to the center of a screen when the coordinates are outside of a prescribed range. CONSTITUTION:A CPU 3 controls respective parts and has respective functions as a detecting means 3A for detecting the coordinate position of hit input data, a judging means 3B for judging whether the detected coordinate position is included in a prescribed range of a screen or not, an arithmetic means 3C for finding out a difference from the center coordinates when the detected position is outside of the range and computing a prescribed moving guantity, and a moving means 3D for moving the contents of the screen in accordance with the moving quantity. The means 3A detects the coordinate position of hit data and the means 3B judges whether the coordinate position is included in the prescribed range of the screen or not. When the position is not included within the prescribed range, the means 3C finds out a difference from the center coordinates and computes a moving variable to be moved on the center of the screen and the means 3D moves the contents of the screen in accordance with the moving quantity.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile display system in an information processing apparatus that uses a graphic display to add or change data. In an information processing apparatus that interactively manipulates data using a graphic display, it is desirable to be able to operate with as few hits as possible.

That is, an important point in operation is how to reduce the number of hits on the screen for moving coordinates.

2. Description of the Related Art In an information processing apparatus that manipulates data using a graphic display, objects are viewed through a window frame called a screen. At this time, if the object to be operated is larger than the window frame, the display range will be expanded and displayed. To get a full view of the object, the user must gradually move the window frame.

[0004] Furthermore, when applying an operation to an object, (
You must proceed with the work while adding two operations to the screen: 1) an operation for the object, and 2) an operation to move the window frame when the operation range is about to go outside the window frame.

[0005]

[Problem to be Solved by the Invention] In such a conventional moving display method, if an object does not fit into the window frame, an operation to move the window frame is required, which makes the operation very complicated. Become. For example, as shown in Figure 6, to draw a line from a to b, hit a and b on the screen in order to draw the line, but if you want to connect the line to c again, click on the window frame. Movement operations are required.

[0006] As described above, since it is necessary to hit the screen in order to move the coordinates on the screen, there is a problem in that the operability is poor. The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a moving display method that can improve operability.

[0007]

[Means for Solving the Problems] FIG. 1 is a diagram illustrating the principle of the present invention. In FIG. 1, 1 is a display for manipulating data, 3A is a detection means for detecting the coordinate position of hit input data, and 3B is for determining whether the detected coordinate position is within a predetermined range of the screen. The determining means, 3C, is a calculation means that calculates the amount of movement by calculating the difference from the central coordinate when the image is outside the range, and 3D is a moving means that moves the screen according to the amount of movement.

[0008]

In the present invention, the coordinate position of hit data is detected, and then it is determined whether the detected coordinate position is within a predetermined range of the screen. If it is not within a predetermined range, the difference from the center coordinates is calculated, the amount of movement is calculated to bring the screen to the center, and the screen is moved according to the amount of movement.

[0009] In this way, there is no need to hit the screen to move the coordinates on the screen, and no movement operation is required, so that operability can be improved.

Embodiments Hereinafter, embodiments of the present invention will be explained based on the drawings. 2 to 5 are diagrams showing an embodiment of the present invention. In FIG. 2, reference numeral 1 denotes a graphic display (display), and the graphic display 1 is connected to the CPU 3 via an interface unit 2.

4 is a coordinate input section for inputting data coordinates, and the coordinate input section 4 is connected to the CP via an interface section 5.
Connected to U3. Reference numeral 6 denotes a disk device (database) from which data is updated and retrieved, and the disk device 6 is connected to the CPU 3 via an interface section 7. The CPU controls each part, as well as detecting means 3A for detecting the coordinate position of hit input data, discriminating means 3B for determining whether the detected coordinate position is within a predetermined range of the screen, and a central It has functions as a calculation means 3C that calculates a predetermined amount of movement by determining the difference with the coordinates, and a movement means 3D that moves the screen according to the amount of movement.

Next, the operation will be explained. FIG. 3 is a flowchart for explaining the operation of the present invention. In FIG. 3, first, in step S1, the center coordinates of the screen are set. The center coordinate d set here is shown in FIG. Next, in step S2, input is made from the coordinate input section 4, and the hit coordinate position is determined. Here, for example, the coordinate position b in FIG. 4 is determined.

Next, it is determined whether the coordinate position obtained in step S3 is within a predetermined range. In Figure 4, e
indicates a predetermined range; in this case, the obtained coordinate position b
is not within the predetermined range e. When the determined coordinate position b is within the predetermined range e, the process ends. Next, when the determined coordinate position b is not within the predetermined range e, the difference from the center coordinate d is determined and the amount of movement is calculated in step S4.

[0014] Then, in step S5, the screen is moved according to the amount of movement. As shown in FIG. 5, c is entered on the screen after the movement, so data can be input consecutively after b. In this way, it is not necessary to hit the screen to move the coordinates on the screen, so the operability can be improved.

[0015]

[Effects of the Invention] As explained above, according to the present invention, when coordinates are outside a predetermined range, they are automatically moved to the center of the screen, so there is no need to perform a screen movement operation. , operability can be improved.
