Abstract

PURPOSE:To simplify the input of directions by setting the sensors, the display parts and the arithmetic parts on the surface of a spherical cube. CONSTITUTION:A 3-dimensional direction input/instruction device contains a spherical cube 1 containing the sensors 7 and supported by a stand 2. Then the vector connecting the fixed center of the cube 1 and a designated position on the surface of the cube 1 is calculated by an arithmetic part for output. A reverse switch 4 functions to perform the input of the direction hidden by the stand 2 and is calculated by the arithmetic part with the upper and lower sides of the switch 4 set opposite to each other. Furthermore the display parts 6 (LEDs) are distributed on the surface of the cube 1 and the arithmetic part calculates the points where the parts 6 hit the cube 6 toward the center of the cube 1. Then the parts 6 around the calculated points are lit up for designation of each direction.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an input device such as a converter, and particularly to a three-dimensional directional input display device.

(Prior Art) With the development of shimmy range transport technology, analysis of objects having a three-dimensional extent is frequently performed, and the results are often displayed graphically. but,
Since the display that displays the results is two-dimensional, it can only display a two-dimensional picture of the three-dimensional object inside the Combita from a certain direction. Therefore, in order to fully understand the results, it is necessary to look at the picture from various directions.

For this reason, it is necessary to appropriately input the direction of a three-dimensional object into the converter. Conventionally, when trying to input a three-dimensional direction on a combination machine, the three-dimensional object inside the combination machine was rotated around a reference line segment and pointed in the direction desired for observation. . The angle can be entered by inputting the rotation angle directly from the keyboard as a numerical value, or by using a device such as a dial or trackball to determine the rotation angle from the rotation angle.

(Problem to be solved by the invention) Conventionally, in the method of inputting the three-dimensional direction of the converter I, the rotation angle to face the direction is inputted instead of directly inputting the direction. It is difficult to input the direction freely as the direction must be converted by the rotation angle E. Furthermore, when deciding a new direction, it is important to understand the current direction. The purpose of this is to further facilitate inputting and displaying the direction by showing the direction.

[Structure of the invention]

(Means for Solving the Problems) The three-dimensional direction input display device of the present invention includes a sensor disposed on the surface of a sphere or a three-dimensional object having a shape similar to the sphere E, a display section, and a calculation section.

(Function) Some input is given from the outside to a sensor placed on the surface of a sphere or a three-dimensional object having a shape similar to a sphere, and a signal from the sensor is used to determine the input position in the arithmetic unit f, and then the position is determined. Calculate the vector connecting the center of the solid and output it to the converter.

Further, the calculation unit calculates the direction indicated by the device from the combeater or from the direction information stored in the device, and the direction is displayed on the display unit based on the calculation.

(Example) An example of the present invention will be shown using the drawings. FIG. 1 shows an example of a three-dimensional directional input and pointing device. Sensor 7 on the surface
A spherical solid body Ill on which are arranged is supported by a stand t2'.

For example, using an array of piezoelectric elements as the sensor 7,
Using pressure as an input (for example, pressing a point on the surface of a three-dimensional object with a finger), it is determined where on the surface of the three-dimensional object the pressure was input. A spherical solid with a sensor placed on the surface (the center of 1+ is fixed, so the calculation unit calculates and outputs a vector connecting the center and a specified position on the surface of the solid. The switch 4 is for inputting the direction hidden in the table 2.By turning on the reverse switch 4, when calculating the direction in the arithmetic section, the position where the input was made can be reversed upside down. Calculate assuming that there is.

If you turn on the reverse switch and specify the direction directly above the object, the direction output to the converter will be directly below. Marker 5 in FIG. 1 is drawn as a guide for the position on the surface of the solid. In addition, LEDs are arranged in a complex manner on the surface of the three-dimensional object as a display section, and the direction from the converter or the direction stored in this device (that is, the viewpoint direction of the three-dimensional object currently displayed on a CRT, etc.) ), the arithmetic unit calculates the point at which the object will collide with the object when moving in that direction from the center of the object, and the direction is displayed by lighting an LED near that point. Further, when the display direction is a part that cannot be displayed, for example, in a direction hidden by the stand ti, the display direction is displayed upside down and the LED is blinked to simultaneously indicate that the display is upside down.

FIG. 2 shows a block diagram of the three-dimensional directional input and pointing device. The sensor array (7) is drawn as a flat surface, but in reality it is arranged on the surface of a sphere or a three-dimensional shape close to a sphere. Electrical signals from this sensor array cause the calculation unit to The input direction is calculated.The result is sent to the converter synchronously or asynchronously in response to a request from the converter.Also, at the same time, the direction information stored in the computer or in this device is sent to the converter. The display section 14 is illuminated (blinked) to indicate the direction.Although the display section 14 is depicted as a flat surface in FIG. 2, it is actually arranged on the surface of a sphere or a three-dimensional object having a shape similar to a sphere.

Figure 3 shows an example using the present three-dimensional direction input device.

Like the keyboard 16 and mouse 17, the display 15Q) is used as an input device for the conbeater, and is used when displaying a three-dimensional object on the display and inputting to the conbeater which direction to display it from.

〔Effect of the invention〕

According to the present invention, direction input can be easily performed using a method close to human intuition.
