The visual patterns of fractal stimuli on a computer screen and the brightness patterns of light projected onto room surfaces have Independently been shown to influence human perceptual responses. It is not clear, however, what effect would result if the same fractal patterns were projected as light patterns on room surfaces. This paper reports on the results of three studies investigating visual interest, visual preference, and mood responses elicited by varying complexities of fractal light patterns projected on walls and floors of an interior space. The results suggest that fractal light patterns of medium to medium-high complexity (quantified by the fractal dimension D = 1.5-1.7) were significantly more visually interesting than other patterns. Crucially, viewing distance did not significantly influence visual interest or visual preference. Based on these studies, the use of medium to medium-high complexity fractal light patterns in interior spaces may be useful for enhancing occupants' visual interest and mood.
