粒子法によるCFDとヘッドマウントディスプレイを用いた津波仮想体験システムの開発

抄録

Since the Tohoku earthquake (March 11, 2011) causes quite a lot of damage to a lot of people , we have been getting much aware of tsunami disaster. While the disaster training is effective for preventing damage by tsunami, we cannot get training in a real tsunami unlike earthquake. The earthquake can be virtually experienced in an earthquake simulation vehicle. For tsunami training as many people as possible, especially children and old persons, we have been developing a portable tsunami virtual reality (VR) system using three key technologies of the head-mounted display (HMD), the laptop computer and the particle-based simulation. We correctly reproduce the tsunami behavior using a particle-based CFD method (SPH) for the purpose of giving tsunami's correct knowledge to trainees. By using the simulated results, we compactly-realized the 3D virtual reality of tsunami using Oculus Rift, one of the recent HMDs, with a small laptop computer.
