Abstract:
A method for visual learning of refuge motion from a building in response to environmental change, comprising:storing (1) a building response function that defines a response of the building and an inside thereof to a specific environmental change in terms of a structure of the building, and (2) a refuge motion function that defines refuge motion of individual persons in the building in terms of both attributes of the individual persons and the response of the building; computing the building response by substituting design values of the structure of the building into the building response function; computing the refuge motion of individual persons by substituting the attributes and the computed building response into the refuge motion function; producing a superposed display of (1) a three-dimensional simulation image of the structure according to the design values, (2) a three-dimensional simulation image of the computed building response, and (3) a three-dimensional simulation image of the computed refuge motion of the individual persons, so as to indicate whether a safety level of said computed refuge motion is sufficient based on a relationship among the three images in the superposed display, the three images being produced under specific viewing conditions including a position and angle of viewing; and when the safety level of said computed refuge motion is indicated as insufficient, seeking a safer refuge motion by a manual modification of the computed refuge motion through a change of at least one of said position and said angle of viewing through use of a joystick and by getting an indication of a safety level of said modification through a superposition of the modification with the structure simulation.
