Introducing Gestural Operation of the Viewpoint in a 3D Virtual Space of a Multiple Perspectives System

Proper spacial information recognition promotes tasks dealing with space design. This paper presents the design, implementation, and evaluation of an interactive tabletop and vertical display system that supports spacial information recognition in tasks. This research focuses on two kinds of viewpoints, the overhead view and the individual view. The proposed system shows both viewpoints. We use a tabletop display for the overhead view and a vertical display for the individual view. The system allows the user to move the object intuitively in each viewpoint by the introduction of the gesture operation. It was investigated whether the gestural operation of the object representing the user him/herself in the virtual space could be compared with the physical object manipulation in the individual view. Statistically significant difference was not found between the two, but the gestural operation in the individual view gave better impression to the users. 1
