Adding haptic feedback in deformable objects is attractive in many applications, such as computer games, interactive cartoon design, and virtual prototyping. In this paper, we propose an interactive haptic deformation approach incorporating the dynamic simulation of mass-spring systems and flexible control of free-form deformation in the touch-enabled modeling of soft-object deformation. Through distributing mass, spring and damping coefficients of the object to the bounded Bezier volume lattice, the deformations of the object in response to the haptic avatar follow the physical laws and acquire high deformation working rate. Both homogenous and inhomogenous materials are simulated, and anchor nodes of haptic input are specified to create amazing effects during the interactive haptic deformation. The experimental results have shown the intuitive and flexible control of the proposed approach.
