The construction method and application of a dynamic user experience evaluation system for smart home appliances

Abstract: The term UX is usually applied in the software field, but it is also used in the hardware product, space and service at present. Apart from the relatively mature UX evaluation methods in the automotive field, the construction of the UX evaluation system in the smart home appliance field is not perfect enough, and there is no exclusive, flexible, and universal evaluation system.One is that smart home appliances are different from traditional products, such as beds and office chairs, and do not require much brain thinking. Smart home appliances still have interfaces to interact with, but they are different from software products, such as mobile phones and computers, which require long-term interaction; Secondly, different household appliances also have their own characteristics, such as washing machines placing more emphasis on interface interaction, refrigerators placing more emphasis on space capacity, and water heaters placing more emphasis on installation; Thirdly, the usage tasks of existing household appliances are constantly changing according to lifestyle trends, and the emergence of new scenarios leads to changes in the task of evaluating smart household appliances. In addition, many evaluation systems have not been effective in improving the R&D process of household appliance in practice. Due to a lack of understanding of the product development process, the R&D design is unable to address the identified issues and truly assist in improving the product experience.In these cases, an evaluation system and application process mechanism for smart household appliances were built. This paper mainly studies four directions: (1) Combining industry analysis and home appliance attributes, define exclusive UX index specifically for home appliances. (2) Expanding UX index into a dynamic evaluation system, which can be reflected in: ① being applicable to different categories of household appliances, assigning index weights based on user, R&D personnel, and market feedback; ② It can be applied to users with different physical states, such as the elderly and ordinary people, to adjust the difficulty of passing the index; ③ It can be applied in different scenarios and tasks, analyzing lifestyle trends and market feedback, predicting the occurrence of new usage scenarios and tasks, and adjusting evaluation system testing tasks. (3) Integrate the UX evaluation system into the development process of new products, form a complete design and testing process, and help products achieve experience optimization continuously. (4) Based on three successful cases, point out the feasibility of the UX evaluation system for improving the home appliance experience and its positive impact on the market.
