<p>PURPOSE:To optionally arrange a position in three-dimensional space by instructing the angle of a face existing in the three-dimensional space, instructing a position on the face and instructing an angle around a vertical line to the face. CONSTITUTION:When a ball is rotated, sensors 4, 5 are also rotated. The rotation is converted into information 111 by a control device 12 and inputted to a computer through a line 14. Where alpha and beta are amts. detected by the sensors 4, 5 with the rotation of the ball 1. When a ring 2, a ball 6 and buttons 9, 10 are operated, information 112 to 115 are similarly generated by the device 12 and sent to the computer. Calculation is executed in the computer and the directions and positions of respective vectors are changed. Based upon these conversion, faces on the three-dimensional space are rotated or moved. The rotation of a face is executed by the rotation of the ball 1. Movement of the face in the (x) or (y) direction after the rotation of the face is executed by the rotation of the ball 6.</p> |
