概要	Computer visualization is widely used to analyze various phenomena in many areas. It is useful to explore the target dataset which has a few physical fields, but it is hard to understand multiple fields simultaneously. Especially, in flow fields, since most datasets have vector field and its associated multiple scalar fields, we are faced with the above problem as long as we rely only on visualization. In this paper, we focus on a multisensory realization method that combines haptization with visualization for the analysis of flow fields. We propose the use of adaptive visual transfer functions which are based on the topological structure of a target scalar field. Haptic transfer functions, which produce three-dimensional forces, are designed to analyze the vector field in a haptic manner. We evaluate the effectiveness of our method using a time-varying three-dimensional wake turbulence dataset.
