Abstract

PURPOSE:To easily confirm the input data and also to improve the operability for input/display of data by displaying the input data at the same position as the data input position. CONSTITUTION:In a tablet device 21, the X and Y directional electrode plates 21b and 21d containing the transparent electrodes are held by the transparent glass plates 21a, 21c and 21e together with an RGB display device 22 set under the plate 21e. A CPU 26 calculates a display position for the same coordinates of the device 22 in accordance with the X and Y directional coordinate information on the device 21 which are inputted from an input interface circuit 23. Then the CPU 26 outputs the information on the calculated display position to the device 22 via an output interface circuit 27. As a result, the coincidence is always secured between the input position and the display position of the information. Thus the input data can be easily confirmed and at the same time the operability is improved for input/display of data.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is based on CAD (computer aided
The present invention relates to an input display control device in a graphic processing system using a computer such as a computer.

(Prior Art) Conventionally, in this type of device, as shown in FIG. The control circuit (CPU) 13 receives coordinate information of a figure, etc., expressed by an input pen (not shown) on the surface of the value input device 12.
was determined and displayed at a predetermined position on a display device 14 such as an RGB display device configured separately.

(Problem to be Solved by the Invention) However, in the above device, data input and data display are performed using separate devices, so unless the displayed data is checked on the display device each time, correct data may not be input. I can't tell if it's true or not. For this reason, there are problems in that the data input operation by the input device becomes slow, and it is troublesome to check the data displayed separately from the input position, which reduces the operability of data input and display.

The present invention has been made in view of the above problems, and by displaying input data at the same position as the input position, the present invention facilitates confirmation of input data and improves the operability of data input display. The purpose is to provide a display control attraction that can be used.

(Means for Solving the Problem) The present invention integrally forms a transparent and flat information input means and a flat information display means, and inputs the information in response to information input from the information input means. It consists of a detection means for detecting the information input position of the means, and a display control means for displaying the corresponding information at the same coordinate position as the information input position of the information input means corresponding to the detected information input position. be.

(Operation) When information is input from the information display means, the detection means detects the information input position of the information input means, and the display control means displays information corresponding to the same coordinate position of the integrated information display means. Display.

Therefore, the input position of the information and the display position of the information always match, making it easier to recognize the information.

(Example) Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2.

FIG. 1 is a block diagram showing a schematic configuration of an input display control device according to the present invention. In the figure, a tablet device 21 which is a coordinate value input device for inputting coordinate value information of a figure, etc. according to the present invention is a flat X-direction electrode plate 21b on which transparent electrodes indicating the X direction on the coordinates are arranged. , X on the coordinates
A flat X-direction electrode plate 21.6 on which transparent electrodes indicating directions are arranged and transparent glass plates 21a, 21c, 21
A flat RGB display device 22 for displaying the above-mentioned coordinate value information is attached below.

Note that the glass plate 21e also serves as the surface glass of the RGB display device 22, and the RGB display device 22 is comprised of, for example, a liquid crystal display device or a plasma display device. Furthermore, although the tablet device 21 and the RGB display device 22 in FIG. 1 are shown separated by a predetermined distance for convenience of explanation, in reality, as shown in FIG. 2, they are integrally formed without any gaps. has been done.

The X-direction electrode plate 21b and the X-direction electrode plate 21d include
Transparent electrodes are arranged at predetermined intervals in the X direction and the X direction, and each of the above electrodes is connected to the input interface circuit 2
3 is connected. Then, the input pen 24 or the glass plate 2 connected to the input interface circuit 23 is connected to the input interface circuit 23.
1a, a current flows through each electrode at the contact position, and the input interface circuit 23 can detect the contact position of the input pen 24 from the X-direction and X-direction electrodes through which the current flows. can. Further, a keyboard 25, which is a character input device for inputting character information, is connected to the input interface circuit 23, and detects character information to be input in response to pressing of each key 25a. In addition,
The input interface circuit 23 is, for example, R3-232.
It consists of C.

The CPO 26 calculates the display position of the same coordinates of the RGB display device 22 corresponding to the X-direction and X-direction coordinate value information of the tablet device 21 inputted from the input interface circuit 23, and uses the information of the display position as, for example, RG.
It is output as a B signal to the RGB display device 22 connected to the output interface circuit 27. In addition, the CPU 26 also controls the input interface circuit 23
It detects character information input from the keyboard 25 via the output interface circuit 27 and outputs RGB signals to the RGB display device 22 via the output interface circuit 27 to display characters corresponding to the character information.

Next, the graphic input/display operation will be explained using the drawing of FIG.

First, when the user uses the input pen 24 to touch the glass plate 21a of the tablet device 21 to draw as shown in FIG. A current flows through the electrodes, and the input interface circuit 23 sequentially outputs the X-direction and X-direction coordinate value information of the tablet device 21 corresponding to the current to the CPU 26. The CPU 26 sends an RGB signal indicating the display position of the same coordinates of the R, GB display device 22 corresponding to the input coordinate value information to a.
The signals are sequentially output to the RGB display device 22 via the color interface circuit 27. Thereby, the RGB display device 22 can create a diagram as shown in FIG. 3 on the display screen by following the movement of the input pen 24 on the tablet device 21 based on the RGB signals.

Therefore, in this embodiment, when the input pen 24 touches the glass plate 21a of the tablet device 21 and moves, a diagram is created at the same coordinate position of the RGB display device 22 following the movement. , the input position of the information and the display position of the information always match, making it easy to recognize the information.
