Maintaining a stable haptic interaction with virtual environments, especially with physically-based deformable objects, has long been an active area of research. We address this issue by presenting a comprehensive haptic system architecture and virtual reality simulation, where a physically-based modeling using the Finite Element Method (FEM) combined with an “elementary displacement” approach has been implemented. This approach ensures the stability of haptic interaction with deformable objects and considers interaction with multipoints contacts. The Future Haptic Science Encyclopedia (FHSE) we developed to verify our proposal and demonstrate the new haptic interface HIRO II. We also present an objective and subjective evaluation of FHSE simulation.
