<p>PURPOSE:To easily control three-dimensional display operation by rotating respective three orthogonal axes X, Y, and Z around the centers of rotation, and leading parameters of rotation out by three rotation detecting devices which detect the respective quantities of rotation. CONSTITUTION:When a spherical part 1 is rotated as shown by an arrow Xr, a rotational component in the direction of the arrow Xr is detected by a rotation detecting device 2 and outputted as the 1st parameter of rotation. Further, when the spherical part 1 is rotated as shown by an arrow Yr, a rotational component in the direction of the arrow Yr is detected by a rotation detecting device 3 and outputted as the 2nd parameter of rotation. Furthermore, when the spherical part 1 is rotated as shown by an arrow Zr, a rotational component in the direction of the arrow Zr is detected by a rotation detecting device 4 and outputted as the 3rd parameter of rotation. The device which operates as mentioned above is used as an external input means to easily control three-dimensional display operation.</p> |
