In order to improve the operation precision of the remote manipulation systems, it is necessary to clarify the human characteristic of length perception by using fingers. In previous studies, the length perception has not been investigated using multi-fingers grasping. Therefore, we developed a tactile length measuring system in this study. By using this system, some experiments were made to clarify the human length perception for fingers (thumb, index finger, middle finger). These results suggest that human tactile length perception in case of three fingers using is better than that of two fingers (thumb and index finger) condition.
