The design exploration of smart wearable glasses for the elderly based on AHP-QFD

Abstract

Nowadays, the demand for smart wearable devices among the elderly is growing steadily. As an emerging wearable device, smart wearable glasses have great potential in assisting the daily lives of elderly individuals. However, existing products generally suffer from issues such as limited functionality, complex operation, and insufficient elderly-friendly design, making it difficult to meet the real needs of elderly users. To scientifically and reasonably improve the daily quality of life for the elderly, and to explore designs that align with the usage needs of this demographic, this study focuses on the design of smart wearable glasses. Through research, a hierarchical analysis model of functional requirements for smart wearable glasses for the elderly is established, and the AHP is used to determine the weight values of various requirements, identifying the key functional needs of the elderly. Next, the QFD method is applied to establish the relationship between user needs and quality characteristics, clarify design requirements, and ultimately obtain an optimized design solution. Finally, the design process of the smart wearable glasses is completed, from identifying pain points to implementing solutions. This study provides a scientific and systematic theoretical approach to the design of smart wearable glasses for the elderly, contributing to improving the elderly-friendliness of the product, enhancing the user experience, and offering theoretical support and practical reference for aging-friendly design.
