The authors have developed a tactile display that is attached to the user's fingertip. The display presents the touch status between the user's finger and a virtual spatial object by a vibratory stimulus. The display is equipped with ten vibrating pins, which are contacted to the surface of an index fingertip or a thumb. By changing the pattern of vibration, the display presents the geometrical features of an object surface such as a vertex, an edge, and a plane. An experiment was performed to confirm the user's discrimination between the patterns. A pick-and-place model task in a virtual space was also performed to reveal the effort of the tactile presentation during virtual object manipulation. The results showed that the tactile presentation improved the task completion time and the positional accuracy of the manipulated object.
