INTRODUCTION Haptic virtual reality (VR) has revolutionized the skill acquisition in dentistry. The strength of the haptic VR system is that it can automatically record the outcome and associated kinematic data on how each step of the task is performed, which are not available in the conventional skill training environments. The aim of this study was to(More)
We have developed a virtual reality (VR) and an augmented reality (AR) dental training simulator utilizing a haptic device. The simulators utilize volumetric force feedback computation and real time modification of the volumetric data. They include a virtual mirror to facilitate indirect vision during a simulated operation. The AR environment allows(More)
The Tokyo Virtual Living Lab is an experimental space based on 3D Internet technology that lets researchers conduct controlled driving and travel studies, including those involving multiple users in the same shared space. This shared-use feature is crucial for analyzing interactive driving behaviors in future smart cities. The lab's novelty is two-fold: it(More)
Serious games became an important device for increasing the awareness of issues that are important to society. One such issue is the environmental impact of driving. To support the training and wide promotion of eco-friendly driving, an appropriate platform and tools are needed. In this paper, we present the Scenario Markup Language (SML), a simple yet(More)
We developed an augmented reality (AR) dental training simulator utilizing a haptic (force feedback) device. A number of dental procedures such as crown preparation and opening access to the pulp can be simulated with various shapes of dental drill. The system allows students to practise surgery in the correct postures as in the actual environment by(More)
This thesis describes a new framework for conducting controlled driving behavior studies based on multiuser networked three-dimensional (3D) virtual environments. The framework supports (a) the simulation of multiuser immersive driving, (b) the visualization of interactive surrounding traffic, (c) the specification and creation of reproducible traffic(More)
