For the development of multi-sensory research in the field of game experience design, the work aims to clarify the necessity and urgency of smell experience in game design, analyze the hot spots and shortcomings of existing research, and discuss the future development trend. Firstly, literature review and case analysis were used to briefly describe the design methods, interactive technologies and application scenarios of multi-sensory research in existing game experience at home and abroad, and to clarify the development and shortcomings of smell in game experience design. Secondly, from the three aspects of method integration, technology breakthrough and creative design, the research of smell in multi-sensory game experience was summarized and sorted out, and highly cited literature was extracted for in-depth analysis and interpretation. Finally, knowledge meta-coding of smell in multi-sensory game experience knowledge fragments in the full text of highly cited literature was carried out, and Sankey Diagram was used to reflect the relationship and weight of data flow. This research focuses on the review and exploration of smell in multi-sensory game experience design. Despite the challenges, smell is expected to become a key element of rich multi-sensory game experience, lead innovative design, give players immersive, emotional and personalized experience, and create new game experience design methods and mechanisms.
