Architectural space can trigger emotion (Zumthor, 2006). Psychologists Mehrabian and Russell (1974) proposed PAD model, presenting eight emotions as a means for psychologists to self-assess the emotional conditions of human experience and to provide people with a way to conceptualize the impact of cognitive structure. The Brain-Computer Interface (BCI) combines with computer operations to decode and calculate different brain waves generated by human emotions, supporting the convenience and wisdom of human life. The integration of the PDA model and BCI technology will offer an understanding of the interactive relationships between space and emotion. The purpose of this research is to construct a computational model called EMO-Space, which can autonomously support space interaction through the understanding of human emotions. Based on the PAD model, the integration of BCI, the mechanism of emotional transformation, and the control of message transmission are explored. Subsequently, the computational model is proposed and simulated. EMO-Space will provide the basis for the intelligence of emotional space in the future, such as in elderly care and spatial healing.
