Designing, implementing, and evaluating intuitive & interactive lighting simulation tools

Abstract

The architectural daylighting interface allows users to model architectural spaces with small scale physical primitives and projects simulations of daylight in the virtual space from six or more projectors. A series of user studies revealed that designers found the language of the physical primitives to be simple, expressive, and powerful. Users gained significant intuition about daylighting, but experienced specific difficulties while using our early system. Users experienced problems judging physical scale and evaluating lighting intensities.
