Abstract: A fire-fighting virtual reality simulator allows the trainee to move in a virtual space in various complex virtual fire disaster situations and perform a suppression of a virtual fire and a confrontation training. An experience interactive simulator for providing a trainee with a floor movement that may occur in a fire disaster situation so that the trainee wearing HMD in a virtual fire-fighting training has the same sense of feeling as that in an actual fire-fighting training is provided. For the realistic content experience, a physical floor movement, such as tilting, falling, and shaking of the floor is reproduced using a base motion, thereby providing a floor movement that enables a sense of feeling similar to a fire disaster situation.

Abstract: A method, performed by an authoring system, of authoring content for a high-precision fire-dynamics-simulation (FDS) is provided. The authoring system selects a target object from an object DB storing a three-dimensional model of each object made to correspond to surface information indicating at least one material constituting a surface of the three-dimensional model and material information indicating fire attribute information of each material; arranges the selected target object in a three-dimensional space to author content for the FDS; converts the content for the FDS into an FDS input file used as an input for a simulator for the FDS; and outputs the FDS input file to the simulator.

Abstract: The present disclosure relates to a method and device based on a viscosity-variable haptic glove using MR fluid. A method for providing haptic feedback through a haptic glove according to an embodiment of the present disclosure may comprise: detecting an object in a virtual reality (VR) space; controlling an electromagnetic field for an actuator based on a magneto-rheological fluid (MR fluid) mounted on the haptic glove based on properties of the detected object; and providing haptic feedback to a user of the haptic glove using properties of the MR fluid that change based on the controlled electromagnetic field.
