Requirement Analysis of Smart Kitchen Dietary and Social Service System Based on Older Adults Mental Models

Using kitchen life as an entry point and the theory of mental modelling, we carried out a study on the needs analysis of a smart kitchen diet and social service system, aiming to meet the new needs of the elderly in terms of health and social interaction. Through questionnaires and user interviews, we collected and analyzed the mental data of the elderly and created a mental model of “diet and social interaction” as well as user requirements. The Analytic Hierarchy Process was used to identify the importance of dietary and social needs, covering the four demand directions of diet and nutrition, health management, social interaction, and health awareness. This study highlights the potential of user-centred research methodology in the health and social care of older people and provides useful guidance and insights for the design of future smart kitchens and related products.
