When we add tactile feedback to a scaled 3D aerial image of a real object, it is necessary to tune the tactile stimulation signal according to the visual scaling. The goal of the paper is to clarify the scaling law of the tactile stimulation signal added to the scaled 3D floating image. As the first step, we clarify the acceptable scaling range of visual 3D image for a constant tactile stimulation. The tested events were collisions between a rigid object in a subject hand and three kinds of balls hung as a pendulum. The results show that there is an acceptable range for each event and the range was comparable throughout the experiments. The results presented here provides the basic knowledge for practical 3D tactile-visual display in mid-air.
