The perception and metaperception of architectural designs communicated by video-computer imaging

Abstract

Non-architects answered multiple-choice questions about depth, size, shape, texture, and conformation in exterior building scenes presented by manual rendering or video-computer techniques including a single viewpoint, multiple viewpoints, and animation. They also rated (a) confidence in their answers, (b) overall judgments of clarity, and (c) overall impressions of realism. The viewing time needed for judgments was also measured. Presentation technique did not affect the viewing time, but it did affect perceptual accuracy and ratings of confidence, clarity, and realism. Animation yielded higher ratings in all categories. It also produced the highest accuracy for depth perception, but the lowest accuracy for size and texture perception. The low accuracy for size and texture was exacerbated by high confidence in the wrong answers. Multiple viewpoints caused neither false confidence nor reduced accuracy in any category, and yielded the highest accuracy in two categories: size and texture. The combined effects on perception and metaperception (knowledge about one's own perceptual processes) suggest that animation creates the best overall impression and is the best for conveying depth information. However, multiple viewpoints are better than animation for conveying size and texture information. These results are discussed with respect to theories of perceptual representation.
