Abstract

PURPOSE:To improve the input operability by using a picture correcting means which corrects previously the inversion of pictures when a reflected image is shown and then writes the picture data to a picture memory. CONSTITUTION:A position where the copying of a graphic pattern is desired is indicated directly by a pen for a reflected image of a screen displayed on a tablet input device 104. This coordinate data is sent to a controller 105 via a signal line 10 and then to a coordinate converting means 107 to undergo the conversion of coordinates. Then, the converted data is sent to the controller 105 via a signal line 12. The controller 105 produces a graphic pattern based on the obtained coordinates and sends it to a picture correcting means 108. The means 108 inverts the graphic pattern in either one of right-left and upper- lower directions and writes it to the corresponding address of a picture memory 109. The graphic pattern written to the memory 109 is converted into video signals by a video signal converting means 110 and displayed on a light emitting display device 100.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an input display device that presents a display image on an input device.

(Prior art) The screen of the display device of a computer system equipped with a tablet input device is usually installed in front of the worker at an almost vertical angle, whereas the screen of the display device of a computer system equipped with a tablet input device is placed close to the horizontal angle in front of the worker. placed at an angle. Therefore, when inputting figures, the input surface on the tablet board and the display surface of the display device are separated in position, and a cursor is presented on the screen at the position corresponding to the input coordinate values, and this movement is monitored. Since it is necessary to perform an input operation by doing so, there is a difficulty in input operations due to the inability to perform operations based on direct instructions. For example, a method to enable input operations by directly instructing the display screen [dyeing] is
As stated in the document "Online 2 Construction and Evaluation of Transparent Tablet with Display for Handwritten Character Recognition" published in Research Application Report Vol. 34, 1985', a transparent material is placed on the display device. There is a method of stacking the tablets that have been made.

In addition, with keyboard input devices, in order to improve input operability, it is effective to not fix the definition of the function of each key but to be able to set it flexibly, but there is some way to do this. It is necessary to present the function of each configured key.

Conventional methods for this purpose include, for example, The 5eybold Report, 10.
As shown in the document "Xerox's 5s TAR" published in Volume 16, 1981, a layout diagram of the keyboard is presented on the CRT screen, There is a way to write the function of each key.

(Problems to be solved by the invention) In the method of combining the above-mentioned display device with a tablet,
In order to enable operation on a desk, a thin display device such as a liquid crystal display device is required, the tablet itself is expensive, and the resolution is reduced. Furthermore, in the case of a keyboard, the function of each key is displayed on the screen in front of it, making it difficult for beginners to visually confirm which key to press.

The object of the present invention is to obtain an input device with good input operability by projecting an image that assists input work onto the position where the input device is installed.

(Means for Solving the Problems) A light-emitting display device, an image memory that stores image data for the display device, and a display device support frame that holds the display device with the image surface facing downward; an input device installed within the display device support frame; and an input device located between the display surface of the display device and the input device for projecting a mirror image of an image of the display device onto the input surface of the input device; Input operability is improved by having a semi-transparent reflector attached to a support frame and an image correction means that corrects inversion of the image in advance when presenting the mirror image and then writes the image data into the image memory. A good data entry display is obtained.

(Function) The present invention solves the problems of the prior art by adopting the above-described configuration.

FIGS. 2(a) and 2(b) are schematic diagrams explaining the present invention in detail. In the figure, 20 indicates a light-emitting display device, and 21 indicates a semi-transparent reflector. The display image (the character string "123" in the case of FIG. 2(a)) of the light-emitting display device 20 is reflected by the semi-transparent reflector 21, and its mirror image 22 is presented to the operator 23. The display image is displayed on the light-emitting display device 20 after the image data is corrected in advance using the method described below so that the mirror image 22 is displayed in the correct orientation.

In the present invention, in order to present a mirror image of the display screen, when the light-emitting display device 20 is originally installed with its ground surface facing toward the front (hereinafter referred to as installation direction 1), it can be viewed laterally and on the opposite side. When the camera is installed facing the camera (hereinafter referred to as installation direction 2), the image is reversed vertically. Therefore, in order to correctly display the image data as a mirror image, it is necessary to invert the displayed characters and figures horizontally or vertically in advance. For example, if we consider a light-emitting display device 20 that has display coordinates on the screen of nXm, a dot that should be displayed on the screen of the light-emitting display device 20 at coordinates (x, y) in a character or figure pattern. , when the light-emitting display device 20 is installed in the installation direction 1, the coordinates are (m-x, y), and when it is installed in the installation direction 2, it is written in the coordinates (x, m-y). Image inversion caused by presenting a mirror image is thus corrected.

(Example) FIG. 1 is a diagram showing an example of the present invention. A light-emitting display device (for example, a CRT display device) 100 is supported by a display device support frame 101 so that the display screen faces downward. The display device support frame 101 is made of an opaque plate-like material and blocks unnecessary incident light from the outside. 1
04 is a tablet input device, the coordinate output of which is sent to the control device 105 via a signal line 10. A semi-transparent reflector (for example, a glass plate) 1o2 is fixed to a reflector support frame 103, and the reflector support frame 103 is configured such that the mirror image of the display screen of the light-emitting display device by the semi-transparent reflector 102 is It is attached to the display device support frame 101 at a position where it is displayed on the tablet input device 104. With the above settings, the tablet input device 104
The input screen and the mirror image of the display screen can be seen superimposed.

In this embodiment, in order to improve input operability, the image on the display screen is presented as a mirror image on the tablet board, and the position of the input coordinates on the image is made to match the input position. device 104
When a dot is presented on the light-emitting display device 100 using the coordinate data obtained as is, the position of the mirror image of the dot on the tablet input device and the input position (pen tip) do not originally match. Therefore, in order to match the two, coordinate data (xt
, yt) can be obtained by the method described in .

(3) Three points PI (Xdl, Ydl) whose coordinate values on the screen are known and which are not lined up in a straight line on the screen of the display device.

Display P2 (Xd2.Yd2) and P3 (Xd3.Yd3). These three points are displayed on a flat surface on the tablet board.

■PL, P2. Indicate the position where P3 is displayed using the input pen. The output of the tablet at this time is Ql (Xtl, Ytl), Q2 (Xt2.Yt2
), Q3 (Xt3.Yt3).

These parameters are calculated prior to the input operation.

Through the above coordinate transformation, the input position and the position of the transformed input coordinates on the display image match, and the operator 25 can directly specify the position on the display image.
Can perform input tasks.

The conversion parameter storage means 106 stores in advance parameters a, b, c, d, e, and f obtained by calculation of equation (2). The coordinate conversion means 107 is the control device 105
tablet input device 1 sent via signal line 12 from
The coordinate output of 04 is subjected to the coordinate transformation shown by equation (1) using the parameters sent from the transformation parameter storage means, and the transformed coordinates are sent to the control device 105. For example, when a dot is displayed at the position of the converted coordinates, the mirror image becomes a dot row indicating the locus of the input pen on the tablet input device 104. The control device 105 controls the above-mentioned devices, inputs coordinate data from the tablet input device 104, or receives and transfers display data to and from other information processing devices via the signal line 13.

The overall operation of this embodiment will be explained by taking as an example the operation of copying the graphic pattern (arrow in the example shown) 24 displayed in FIG. 2(b) to a specific location in the image. On the mirror image of the screen displayed on the tablet input device 104, the operator directly indicates with a pen the position 25 where the graphic pattern is to be copied.

This coordinate data is sent to the control device 105 via the signal line 10, and further sent to the coordinate transformation means 107, where it is subjected to the coordinate transformation shown by equation (1). The converted coordinates are sent to the control device 105 via the signal line 12. The control device 1
05 generates a graphic pattern based on the obtained coordinates and sends it to the image correction means 108 via the signal line 11. The image correction means 108 inverts the obtained graphic pattern either horizontally or vertically and writes it into the corresponding address of the image memory 109. The graphic pattern written in the image memory 109 is converted into a video signal by the video signal conversion means 109 and displayed on the light-emitting display device 100.

In this way, the operator can copy the graphic pattern by directly indicating the target position in the image.

Also, by using a keyboard as an input device,
A display device that can easily display the function of each key can be obtained. That is, the tablet input device shown in FIG. 1 104 is replaced with a keyboard, on which a mirror image of a pattern showing the function of each key is presented by the light-emitting display device 20. By changing the displayed image, the contents of the function display of each key can be easily changed. Furthermore, since the display is shown directly at the position of each key, the operator can visually confirm his or her hand and the key to be pressed, making the work easy even for beginners. Furthermore, since a mirror image is presented, there is an advantage that the display of each key is not obscured by hands, arms, etc.

Furthermore, by moving the mounting portion shown in FIG. 1 120 in the vertical direction and in the rotational direction around the axis, the display position of the screen can be set not only on the input device but also in various positions. FIGS. 3(a) and 3(b) show the semi-transparent reflector 2.
1 shows changes in the presentation position of the mirror image 22 when the inclination angle of the mirror image 22 is changed. That is, by changing the inclination angle of the semi-transparent reflector 21 from 45 degrees to 0 degrees with respect to the horizontal plane, the mirror image 22 is vertical (third angle) when viewed from the worker 23.
It changes from 22) in Figure 3(a) to horizontal (22 in Figure 3(b)). Similarly, FIGS. 3(c) and 3(d) show the semi-transparent reflector 2.
1 is changed in the vertical direction. By moving the semi-transparent reflecting plate 21 downward, the mirror image 22 is moved in parallel while maintaining its inclination. The parts indicated by dotted lines in Fig. 3(b) and (d) are
Semi-transparent reflector plate 2 in FIGS. 3(a) and (C), respectively.
1 and the mirror image 22 are shown superimposed on the same figure for comparison.

(Effects of the Invention) As is clear from the above description, the input display device of the present invention improves input operability by presenting an image that assists input work on the input surface of the input device. can do.
