Technology and science have been developing rapidly, and robotic system for human support has been researched recently. Considering the effect of low birthrate and longevity, this system is thought to become important in the future. In this research, environmental embedded haptic system for human support is developed. Action recognition and support is realized by the concept based on the modal transformation, which is often used for haptic research. In order to realize this system, variable impedance control based on making a choice of environmental modes is proposed. This system enables action recognition and support for human motion. The validity of the proposed method is shown by the experimental results.
