MODELING OF LOCATION AND DIRECTION OF VIEWER'S EYE IN MUSEUM FOR LIGHTING DESIGN

摘要

The primary aims of lighting design of a museum should be to provide museum viewers with clearand comfortable views of exhibits in a museum and to avoid uncomfortable eyestrains during their walk around the museum. In order to achieve these aims, lighting design should follow next steps; first to predict viewers' eye-locations and their directions, and then to generate luminance images from these eye-locations with these eye-directions, and finally to examine luminance images generated. Authors went through two steps for this research. First, the authors carried out a experiment to record location and direction of eyes of visitors of regular exhibition rooms of Tokyo National Museum. Visitors selected for the survey were asked to mount a pinhole video camera on their foreheads, and movies pictured by the cameras were recorded. About 30 visitors participated in the survey. By the movies recorded, the authors read eye-location and eye-direction of the participants every 1 second. Next, a survey was carried out to evaluate light environment on major routes and points where many viewers move or look, based on the results of first experiment. They examined the evaluations of visitors with physical value such as luminance of visual objects and average of travelling time. Finally, they created some guidelines for lighting design based on location and direction and direction of viewer's eye.
