1Apart from m
1In like manner, shown in Fig. 7 (C), as the user with the nib of pointer 34 for the pointer of naming a person for a particular job from the direction of originally vertical pedestal 32 towards the left tilt angle theta
2The time, the shown object S of screen 30 will along with from position originally to the left mobile phase corresponding to tilt angle theta
2Apart from m
2In fact, tilt angle theta
1, θ
2With distance m
1, m
2Between corresponding relation can set up on their own for system default value or by the user, be not subjected to certain restriction.Similarly, if pointer 34 by the direction of vertical pedestal 32 originally towards close/away from screen orientation inclination certain angle, the shown object S of screen 30 also can be from position originally upward/the below mobile phase is corresponding to the distance of this angle.
