Psychological Evaluation of Outdoor Pedestrian Lighting Based on Rendered Images by Computer Graphics.

Abstract

Various lighting envi onments of residential streets were simulated by computer g aphics. By means of these visualized images, subjective impressions of outdoo pedestrian lighting were investigated. As a res ilt, the following th ee points were clarified ; (1) Subjective impressions of night-time tesidential streets, could be classified into three groups. namely <brightness> impression, <uniformity> impression and <comfort> impression, including impression of secu ity ; (2) The combination of E (ave) and Ev (min) is important for ealizing a comfortable and functional lighting environment in residential area, because these two photometric values had relatively good co elations with the two factors of subjective imp essions ; and (3) Observing compute graphic images, the s ;bjects could easily assess imp essions. Furthermore, variovs parameters can be easily 8nd systematically changed o kept co stant by CG. Computer graphics can be, therefo e, one of the e?fective methods for appraisal of subjective impressions received ftom the lighting environment.

Urban Park Lighting Quality Perception: An Immersive Virtual Reality Experiment

“…Flynn et al [27] listed several rating scales that have been discovered to discern between lighted spaces in measuring perceived qualities referring to visual clarity, spaciousness, evaluative responses, social prominence, complexity, spatial modifiers, etc. Shikakura and Kikuchi [30] classified the subjective impression of outdoor lighting into three groups: brightness, comfort, and uniformity. Johansson et al [31] investigated the potential predictors for the perceived visual accessibility and the perceived danger of an urban footpath.…”
