Abstract
There is provided a track ball type data input apparatus which can input data showing the movement in the direction vertical to the image or the rotation around the axis vertical to the image and visually and easily assures the operation flexibility in the threedimensional inputs. In this apparatus, the first encoder and the second encoder are driven by rotating the spherical manipulator called a track ball and the pulse outputs obtained from the encoders cause an object displayed in the image to move or rotate. When the attitude sensor detects inclination of the body case, the coordinate axes are rotated depending on the direction and angle of inclination and are then converted. Thereby the object can be moved or rotated with reference to the converted coordinate axes. Moreover, the moving operation control mode and rotating operation control mode can be switched by manipulating the mode switching button.
