Abstract
Augmented Reality enables people to remain connected with the physical environment they are in, and invites them to look at the world from new and alternative perspectives. There has been an increasing interest in emergency evacuation applications for mobile devices. Nearly all the smart phones these days are Wi-Fi and GPS enabled. In this paper, we propose a novel emergency evacuation system that will help people to safely evacuate a building in case of an emergency situation. It will further enhance knowledge and understanding of where the exits are in the building and safety evacuation procedures. We have applied mobile augmented reality (mobile AR) to create an application with Unity 3D gaming engine. We show how the mobile AR application is able to display a 3D model of the building and animation of people evacuation using markers and web camera. The system gives a visual representation of a building in 3D space, allowing people to see where exits are in the building through the use of a smart phone or tablets. Pilot studies were conducted with the system showing its partial success and demonstrated the effectiveness of the application in emergency evacuation. Our computer vision methods give good results when the markers are closer to the camera, but accuracy decreases when the markers are far away from the camera.
