The Effect of Control Resolution on the Usability of Color-Tunable Lighting Systems

摘要

Color-tunable lighting systems with inappropriate resolutions may confuse end-users and prevent them from easily specifying their desired colors. To improve the design of color-tunable systems, a psychophysical experiment explored the independent and interacting effects of hue, saturation, and luminance control resolutions on usability. Three criteria-efficiency, effectiveness, and satisfaction-were used to evaluate these effects. Results showed that combinations of middle-range hue resolution and saturation resolution facilitated the greatest usability. When luminance control was independent of hue and saturation control, luminance resolution did not significantly impact usability.
