This book presents principles and theoretical background to develop a Virtual Reality system that links physical simulations and haptic rendering. Special attention is given to the modeling and computation of contact forces in a two-finger grasp of textiles.

The focus from most Virtual Reality (VR) systems lies mainly on the visual immersion of the user. But the emphasis only on the visual perception is insufficient for some applications as the user is limited in his interactions within the VR. Therefore the textbook presents the principles and theoretical background to develop a VR system that is able to create a link between physical simulations and haptic rendering which requires update rates of 1,kHz for the force feedback. Special attention is given to the modeling and computation of contact forces in a two-finger grasp of textiles. Addressing further the perception of small scale surface properties like roughness, novel algorithms are presented that are not only able to consider the highly dynamic behaviour of textiles but also capable of computing the small forces needed for the tactile rendering at the contact point. Final analysis of the entire VR system is being made showing the problems and the solutions found in the work

Introduction to haptic rendering with comprehensive review of the mechanical foundation and mathematical calculation Showing the steps required for real-time simulation of deformable objects especially textile materials Highlighting the issues in haptic real-time computation and providing approaches to the solution of force rendering of the two-finger mechanical contact grasping a textile Includes supplementary material: sn.pub/extras
