Tactile display for handheld devices requires compact hardware and useful applications. We have proposed the concept of 'Virtual Active Touch' that implements virtual exploration with a cursor on a screen through a pointing-stick-type tactile interface. The first objective was to confirm that our previously proposed friction display method could be applied in virtual active touch. The second objective was to develop a new approach to haptic display of surface shape induced by cutaneous sensation of friction. First, we compared friction sensations perceived through the pointing-stick-type tactile interface with those through a linear-slider-type tactile interface, which allowed actual hand movement. Psychophysical experiments showed that the proposed friction display method could deliver perceived friction corresponding to the friction coefficient as well as the linear-slider-type with slightly less sensitivity to changes in friction coefficient. Second, we evaluated the perception of surface height in the context of bumped shape induced by the friction display. The experimental results agreed with our expectation that faster and longer increases in the magnitude of friction sensation were perceived as higher bumped shapes.
