Development of the multi-sensory augmented DDC (Direct digital control) to improve the cognitive characteristic of the nursery facilities

Abstract

In this study, EEG and Vibra image are compared and analyzed in the environmental test room due to the multi-sensory stimulation of sound fluctuation of 4 types, sound volume of 3 types, color temperature of 3 types and aroma of 3 types. The paper aims to find optimal multi-sensory stimulation and to develop the multi-sensory augmented DDC to increase the cognitive characteristic of the nursery facilities. The condition of the environmental test room was in temperature 25[℃], relative humidity 50[RH%], air current speed 0.02[m/s] and illumination 1000[lux]. The result of this study, at sound fluctuation a=2.1968 music, color temperature 2,700[K], and Lavender scent, relative Mβ wave and SMR/θ were increased, and vibra image of tension/anxiety were decreased. Therefore multi-sensory stimulation of sound fluctuation a=2.1968 music, color temperature 2,700[K], and Lavender scent effects to increase the cognitive characteristic. This paper researched to find optimal multi-sensory stimulation and to develop the multi-sensory augmented DDC to increase the cognitive characteristic of the nursery facilities. © Research India Publications.
