Digital fabrication often requires a mixed initial interaction among the fabrication tools and
the information behind it that is hard to align with users owing to the nature of a coexisting
environment. This type of real-time digital fabrication process needs a cluster of sensing agents
that can sense the needs of users in the environment and respond to users in real time. We
propose a behavior sensing mechanism during the fabricating process. Our goal of this study
is to improve the accuracy between the virtual data and the physical environment and enhance
the smoothness of behavior feedbacks. We defined our own gesture identification rule to help
users manage their fabrication process more easily. Besides, we also extend the possibility and
the flexibility of the sensing mechanism to assist in human–machine collaboration with this
specific coexisting design environment.
