We constructed a haptic presentation system based on haptic primary color which reproduces various tactile sensations of real materials for interactive VR application. This system consists of two components of wearable tactile display which presents vibration and temperature stimuli and stationary encounter-type haptic display which presents force stimulus. The parameter sets of each stimulus was tuned in advance in order to reproduce tactile sensations of thirteen real material samples. To evaluate this system, we conducted two experiments. In the first, how much influence of force presentation was examined, and it was found that evaluated similarities of most samples were improved by presence of force sense. In the second, multiple regression analysis was conducted to estimate the contribution ratio of each stimulus, and it was found that each material sample had particular weights of stimuli for reproducing the tactile sensation.
