Industrial design already dominated by the Internet of Things and big data technology, from now on it have not only serving the visual and auditory senses, but also now focus on multi-sensory design. This article explores the demand scenarios, design ideas and future development directions of olfactory informatization product design by reviewing the historical development of olfactory informatization products, taking the demand scenarios, implementation technologies and product forms of existing olfactory informatization products as the research objects, and combining sensory design and interactive experience design to discuss, analyzes and summarizes the design direction of olfactory informatization under the existing scientific and technological means. In the future olfactory informatization will inevitably intervene into industrial design. It will not only help products realize innovation, but also enrich product functions and complete design experience. Multi-sensory exploration connect the relationship between people and design, and also in line with the guiding ideology of innovative design in the new era of our country.
