Reactive virtual human system with haptic sensation and adaptive function

We have proposed a human-scale interaction system (i.e. reactive virtual human system) with haptic sensation. This system is composed of a wire-based haptic interface and an immersive virtual environment (VE). Based on the framework, we realized virtual catch ball that a user can play a virtual human with a feeling of contacting real ball. To make a database of virtual human´s natural reaction, we implemented reactive motion capture system that can capture movements with physical reaction in close interpersonal engagements. In this paper, we further show the system´s extended function that new motions can reflect on virtual human´s behavioral structure by an on-line motion capture. It will be a practical way to produce various motion patterns during playing, and to enforce virtual human´s adaptive function
