ABSTRACT:
The system creates the aggregate of virtual particles in a cybernetic space on a computer and displays the shape of an object by means of a film covering its surface. When a user inputs a deforming designation, each particle moves and deforms the film. At this time the shape, sense of touch and counter force are output from the computer, and the user can deform the object with a feeling of working clay.
