Abstract

PURPOSE:To improve the operability of a multi-variable coordinate input in a control of a pseudo three-dimension picture display by providing the 1st operation section outputting a parameter for coordinate input and the 2nd operation section provided in parallel. CONSTITUTION:When the 1st operation section 1a is moved on a reflection plate 1c, three kinds of parameters are obtained by the movement and the parameters are inputted to a picture processor as a moving amount as to X, Y, Z axes of a pseudo three-dimension display picture. Thus, a display picture 9 is moved in X1, Y1, Z1 directions. Further, the parameter of the 2nd operation section 1b is inputted to the picture processor as a turning amount around the X, Y, Z axes of the pseudo three-dimension display picture. Thus, a picture 9 is turned in the directions of X2, Y2, Z2. Thus, the operator uses the operation sections 1a, 1b together to attain multi-variable coordinate input easily. That is, the operability of the multi-variable coordinate input in the control of the pseudo three-dimension picture display is improved.

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention is directed to a coordinate input device for controlling three-dimensional (11ii) display.

[Technical background of the invention and its problems] Trackball devices are generally used to control image display, but conventional trackball devices have two
Since it was used only for dimensional position specification and display control, it was sufficient to have a two-dimensional displacement function.

However, in recent years, three-dimensional images have been displayed on displays (this is called pseudo three-dimensional image display), and conventional trackball devices with two-dimensional displacement functions are no longer functionally sufficient. . Because pseudo 3
Space in dimensional display! This is because it is necessary to input a total of six types of parameters: three types of parameters related to the viewpoint position at Mark J1 and three types of parameters related to the rotation of the object about each of the three orthogonal axes.

Although it is possible to control pseudo three-dimensional image display by using a plurality of conventional trackball devices with two-dimensional displacement functions or by switching one trackball as appropriate, such coordinate input is difficult. Experience has shown that if this is the case, operations cannot be performed in accordance with the operator's intuition, resulting in poor operability.
