This paper presents a novel general-purpose simulation analysis application that combines concurrent operations simulation with the advanced data interrogation and user interaction capabilities of immersive virtual reality systems. The application allows for interactive modification of the simulation parameters, while providing the users with the available… (More)
This paper demonstrates the utilization of immersive virtual reality environments in the investigation of operations simulation results. The authors outline the benefits offered by virtual reality over the traditional two-dimensional computer interfaces, such as the monitor, keyboard and mouse. The paper describes the state of the art in the area of… (More)
The traditional computer interface provides a two-dimensional (2D) interface to design. The monitor is a two-dimensional visual display and the desktop mouse is a two-dimensional input device. These tools are sufficient for designing 2D products such as planar linkages. When these tools are used to design three-dimensional (3D) products however, the… (More)
This paper presents a screw theory based approach for the analysis and synthesis of flexible joints using wire and sheet flexures. The focus is on designing flexure systems that have a simple geometry, i.e. a parallel constraint pattern. We provide a systematic formulation of the constraint-based approach which has been mainly developed by precision… (More)
Natural orifice translumenal endoscopic surgery (NOTES) procedures are rapidly being developed in diverse surgical fields. We are developing a Virtual Translumenal Endoscopic Surgery Trainer (VTEST™) built on a modularized platform that facilitates rapid development of virtual reality (VR) NOTES simulators. Both the hardware interface and software… (More)
