The goals of seismic impact assessment can be achieved by seismic monitoring systems and seismic impact simulator. Seismic monitoring system, for the purpose of hazard analysis, local site effects analysis, vulnerability analysis, and estimation of loss, is one application of SHM in earthquake engineering. A prototype, conceptual seismic impact simulator integrating SHM, FEM, GIS, and Virtual R...

Mastoidectomy is one of the most common surgical procedures relating to the petrous bone. In this paper we describe our preliminary results in the realization of a virtual reality mastoidectomy simulator. Our system is designed to work on patient-specific volumetric object models directly derived from 3D CT and MRI images. The paper summarizes the detailed task analysis performed in order to de...

We present a large-scale simulation tool for real-time 3D reconstruction of brain activity in a virtual reality environment. The 3D interactive visualization of the human cortex connectome in virtual reality is achieved by using a gaming engine (Unity 3D). Further, the visualization is bi-directionally interfaced with a real-time neuronal simulator, iqr. As a result, by stimulating populations ...

In the past few years virtual reality based systems have been proposed and realized for many medical interventions. These simulators have the potential to provide training on a wide variety of pathologies. So far, realistic generation of anatomical variance and pathologies have not been treated as a specific issue. We report on a cellular automaton, specially developed to generate macroscopic f...

Objective. To assess the face, content, and construct validity of the Voxel-Man TempoSurg Virtual Reality simulator. Participants and Methods. 74 ear, nose, and throat (ENT) surgeons participated. They were assigned to one of two groups according to their level of expertise: the expert group (n = 16) and the novice group (n = 58). The participants performed four temporal bone dissection tasks o...

It is very costly to conduct experiments to test smart environments installed in large-scale public spaces (e.g. airports and railway stations). As a tool to examine the design of such experiments beforehand, we developed a multiagent simulator integrating a large number of software agents and humans into a crowd that can produce complex group behaviors. In the testing of our emergency guidance...
