A teleexistence manipulation system was evaluated quantitatively by comparing tasks of tracking a randomly moving target under several operational conditions. The effects of various characteristics, e.g., binocular vision and the effect of natural arrangement of the head and the arm, are analyzed by comparing quantitatively the results under these operational conditions. A human tracking transfer function was measured and used for comparison. The results revealed the significant dominance of the binocular vision with natural arrangement of the head and arm, which is the most important characteristic of teleexistence.
