Surface-Based Virtual Dental Surgical Simulator using Haptic Display

Haptic Display for a Virtual Reality Simulator for Flexible Endoscopy

A simulation system for flexible endoscopy is described, based on virtual reality techniques. The physician moves the flexible endoscope inside a pipe, in which forces are applied to it. In addition the navigation wheels provide force feedback from the bending of the endoscope’s tip. The paper focuses on the special purpose haptic display which actively generates forces to model the complex int...

Development of a Dental Skills Training Simulator Using Virtual Reality and Haptic Device

The traditional approach to dental skills training has drawbacks in terms of cost, availability, and lack of real-world cases. We develop a virtual reality (VR) dental training system utilizing a haptic (force feedback) device. We generate three-dimensional surface model of the teeth from patient’s data and a realistic model of a dental handpiece with a cylindrical cutting burr. Collision detec...

A Virtual Reality Simulator Based on Haptic Hard Constraints

Experiments in Surface Perception using a Fingertip Haptic Display

Experiments in Surface Perception using a Fingertip Haptic Display by Steven Craig Venema Chairperson of Supervisory Committee: Professor Blake Hannaford Department of Electrical Engineering A haptic display provides the mechanical analog of a physical environment for our sense of touch in a virtual reality (VR) simulation system. In this dissertation, we explore the design and implementation o...

Construct validity and expert benchmarking of the haptic virtual reality dental simulator.

The aim of this study was to demonstrate construct validation of the haptic virtual reality (VR) dental simulator and to define expert benchmarking criteria for skills assessment. Thirty-four self-selected participants (fourteen novices, fourteen intermediates, and six experts in endodontics) at one dental school performed ten repetitions of three mode tasks of endodontic cavity preparation: ea...
