Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an information input/output device suitable for use in, for example, a so-called man-machine interface that mediates between humans and machines.

BACKGROUND TECHNOLOGY AND ITS ISSUE Various devices have been proposed for inputting information from humans into machines. The so-called joy 5tick, in which the volume shaft moves by moving, or in the X-axis direction,
It consists of two LEDs that detect the Y-axis direction and a photosensor. When this is moved over a special board (mouse pad) coated with different colored coatings vertically and horizontally in a grid pattern, the reflected light enters the photosensor. An example is a device that reads the position of a mouse.

These devices are currently widely used as easy information input devices, and are especially convenient when simply inputting two-dimensional information on the X and Y axes.

However, in the case of such a conventional device, it is difficult to manually input information on the positions of points A, B, C, and D, as shown in FIG. Then, since there are many degrees of freedom, there are disadvantages such as inputting time.

However, it seems that there will be no problem if a dedicated switch is used for this purpose, but as shown in Figure 1B, it is not possible to change the number of input points from A' to E', for example. Have difficulty.

In other words, in the case of the conventional device, input is performed manually from one side to the other. Since it is a so-called one-way system, input information cannot be changed in any way during the process, and there are limits to its degree of freedom or its characteristics, which naturally limits its uses.

Furthermore, if the judgment result in step (16) is NO, the process proceeds to step (18), where the difference between the predetermined position information XD at position P0 and the supplied current position information X is less than or equal to the predetermined value Δl. Determine whether it exists or not. If the result of this judgment is YES, the process proceeds to step (I9), where the predetermined position information XO and the current position information fI! X
