Haptic interaction in virtual environments

TLDR
A haptic rendering framework that allows the tactile display of complex virtual environments and reduces the task of the haptic servo control loop to the minimization of the error between user's position and that of the proxy.
Abstract
We present a haptic rendering framework that allows the tactile display of complex virtual environments. This framework allows surface constraints, surface shading, friction, texture and other effects to be modeled solely by updating the position of a representative object, the "virtual proxy". This abstraction reduces the task of the haptic servo control loop to the minimization of the error between user's position and that of the proxy. This framework has been implemented in a system that is able to haptically render virtual environments of a complexity that is near and often in excess of the capabilities of current interactive graphic systems.

Realistic virtual grasping

TL;DR: This work presents a physically-based approach to grasping and manipulation of virtual objects that produces visually realistic results, addresses the problem of visual interpenetration of hand and object models, and performs force rendering for force-feedback gloves in a single framework.

Real-time simulation of physically realistic global deformations

TL;DR: In this thesis, an alternative real-time solution without compromising the mass matrix in the FEM system is presented, instead of decoupling the system by diagonalizing the mass and damping matrix, which improves the sparsity of the system.
