The current research deals with emotion and its reflections in interior design, and in the first chapter, the research problem was identified through a pause of insight, reflection and extensive study of the extent of the possibility of representing emotion and shedding light on it according to what the research seeks to express, which theorizing in the field of interior design has not been exposed to. Being a cognitive addition to researchers in the field of interior design in the College of Fine Arts and its corresponding colleges, in order to benefit from a scientific material that is unique in dealing with the single emotion and its reflections in the designs of public interior spaces by studying the stimuli and design structures that ensure that this is achieved, and the objectives of the research were determined by revealing Emotion and the extent of its reflections in translating positive human feelings, in order to reach interior designs that have their thoughts and emotional content.
