Summary :

Visible light communication (VLC) will play a wide variety of important roles in future communication services. This paper deals with color shift keying (CSK) for the modulation of visible light communications. There are some previous studies about psychological and physiological effects of colors. These studies implied that color offset CSKs have psychological and physiological effects, which normal CSK doesn't have. This paper evaluates the psychological and physiological effects of color offset CSKs compared with normal CSK based on interviews and electroencephalogram (alpha wave, beta wave, and P300) measurements. This study evaluates the feasibility of visible light communication providing added value by measuring arousal, rest, visual attraction, task performance, capacity of working memory, and response for the CSK codes. The results showed that red-, green- and blue-offset CSK have specific features. Red-offset CSK induces excitement and increasing wakefulness levels, attracts attention, enlarges capacity of working memory, raises task performance, and induces fast responses. Green-offset CSK maintains rest levels, elevates relaxation levels, reduces stress, raises task performance, and induces fast responses. Blue-offset CSK maintains rest levels and induces fast responses. It is thought that we can use color offset CSK appropriately and provide added value to their application by considering the results of psychological and physiological investigations. Red-offset CSK is thought to be suitable for commercial advertisements. Green- and blue-offset CSK are thought to be suitable for wireless communication environments in hospitals. Red- and green-offset CSK are thought to be suitable for wireless communication environments in business. Red-, green- and blue-offset CSK are thought to be suitable for use in intelligent transportation systems (ITS).
