Automatic lighting control middleware system controlled by user’s emotion based on EEG

Recently, human-centered technology development is in the limelight. It reflects user characteristics, including the physical and psychological characteristics of humans. In particular, numerous intelligent systems have been developed to prove humans with the services required for a living space. In this study, a middleware system was developed to analyze a user’s emotions using brain waves to control the brightness and color of light accordingly. The middleware in a smart building analyzes the brain waves acquired from the sensors of each household and uses this information to appropriately control the brightness and color of the light in the proper space. Such a system could be utilized in a variety of fields. For example, an intelligent apartment could provide a comfortable indoor environment, as well as save energy, and light therapy could be used to treat depression and insomniac. © Springer Science+Business Media Singapore 2016.
