Journal ArticleDOI
An experimental study on the role of touch in shared virtual environments
TL;DR: The outcomes of this research can have a powerful impact on the development of next-generation human-computer interfaces and network protocols that integrate touch and force feedback technology into the internet, development of protocols and techniques for collaborative teleoperation such as hazardous material removal, space station.
Journal ArticleDOI
Virtual environments for medical training: graphical and haptic simulation of laparoscopic common bile duct exploration
TL;DR: A computer-based training system to simulate laparoscopic procedures in virtual environments for medical training and can be trained to grasp and insert a flexible and freely moving catheter into the deformable cystic duct invirtual environments.
Journal ArticleDOI
Efficient Point-Based Rendering Techniques for Haptic Display of Virtual Objects
TL;DR: An efficient haptic rendering method for displaying the feel of 3-D polyhedral objects in virtual environments (VEs) using a hierarchical database, multithreading techniques, and efficient search procedures to reduce the computational time.
Ray-based haptic rendering technique for displaying shape and texture of 3D objects in virtual environments
TL;DR: A set of software algorithms that work with a force reflecting haptic interface and enable the user to touch and feel arbitrary 3D polyhedral virtual objects in virtual environments are developed.
