When we work in virtual space, we need input device for measuring spatial motion of a human hand. In this research, we use force display for input device which generates reaction force from virtual object. We developed an operation system of virtual space. The system supports easy construction of virtual environment. Using this system, we developed a program that enables two users to work simultaneously in the same virtual environment. Through experiments of deformation of virtual objects, effectiveness of cooperative work in virtual space is tested.
