To obtain specifications for an effective tactile display in virtual reality and tele-existence systems, we developed a matrix type experimental tactile display. It has an 8 by 8 stimulus pin array of 0.3 mm in diameter and with a 1 or 1.8 mm pin pitch. Operators can feel various combinations of pins protruding according to concave and convex portions of virtual textures composed of crossed-axis patterns. We evaluated the matrix type tactile display with two psychophysical experimental methods. In the adjustment method, human subjects adjusted the crossing angle of a comparison texture to bring it as close as possible to a standard texture fixed during the experiment to obtain crossed-axis angle thresholds from the difference between the crossed-axis angles of comparison and standard textures. In the constant stimuli method, many random pairs of comparison and standard textures were presented, and human subjects judged whether the crossed-axis angle of the standard texture coincided with the comparison texture to obtain thresholds with the statistical procedure of the judgments. After seven human subjects performed the abovementioned adjustment and constant stimuli methods, we found that the threshold of the adjustment method was almost the same as that of the constant stimuli method ; but the total time consumption of the constant stimuli was about four times larger than the adjustment method.
