Abstract-Many researchers have worked on the measurement of emotion from the perspectives of their various domains, but there is little research on emotion in interaction in the architecture domain. To develop measures of emotion in interaction associated with spaces, this paper reviews representative studies and techniques adopted for the measurement of emotion in Human-Computer Interaction. Emotional states and emotional response are two important factors to be considered in measuring emotion. In general, emotional states are divided into discrete and dimensional emotion models, whereas emotional responses are organized in terms of experiential, physiological, and behavior response. A critical review would enable the consolidation of knowledge to develop appropriate measures for emotion in interaction design. Through an exhaustive search on contents pages of articles, systematic methods for measuring emotional states and responses were examined, and several problems specific to the measurement of each emotion component were investigated.Index Terms-Emotion, measurements, multi-componential response, experiential response, physiological response, behavior response. I. INTRODUCTIONHuman-Computer Interaction (HCI) has become a promising research area. A significant number of researches have been conducted on smart technologies, where a long-running discussion has been taking place within the HCI domain about usability and user experience (UX) issues [1]. HCI researchers are aware of the limitations of the traditional usability framework, which primarily focuses on user performance. To extend the capacity of the framework beyond reflecting HCI's concern with productivity, these researchers began paying attention to the notion of UX, shifting the focus to user affect and emotion [2]- [4]. The traditional usability methodologies have been regarded as ill-suited to the measures of emotion because there are limitations in accounting for and evaluating emotions [1], [5]. In this paper, we discuss affective and emotional aspects of interaction in smart technologies. The paper provides an overview of current research theories and studies into the measurement of emotion in HCI to develop measures of emotion in interaction associated with spaces. It is expected that the consolidation of knowledge related to the measurement of emotions would be provided to develop appropriate measures for emotion in interaction design.

II. DEFINING AND MEASURING EMOTIONSVarious definitions of emotion exist in different domains such as psychology, neuroscience and design; thus, it is not easy to reach consensus on the definition of emotion. The various dom...
