With the continuous maturity of smart home technology, elderly users who have higher requirements for life quality are becoming powerful consumers of smart home appliances. However, the current smart home products ignore the needs and characteristics of elderly users, making them inconvenient to operate and have poor experience in using products. With the elderly users as the research object, the work aims to improve their experience of using smart kitchen appliances. At the smart home level, the elderly-friendly strategy of relevant brands and market segmentation of kitchen appliances are analyzed, and the development trend and design opportunities of elderly-friendly kitchen appliances are summarized. At the elderly-friendly level, the characteristics of elderly users and their needs and usage habits in kitchen appliances scenarios are studied by constructing user portraits and user journey maps. In the design research stage, elderly-friendly design guidelines are taken as the theoretical guidance. Combined with the cognitive habits of elderly users and the findings of technical research, a smart kitchen appliance product design that is both intelligent and inclusive is completed. It allows the elderly to use kitchen appliances more comfortably, and also allows them to easily enjoy the convenience brought by smart technology after using the elderly-friendly human-computer interaction.
