Objective : This study aims to explore the potential for developing walker designs that simultaneously address the physical comfort and psychological well-being of older adults in preparation for South Korea's transition into a super-aged society. To achieve this, the study applies the seven principles of universal design and the design thinking process to reflect the diverse needs of older adults. It proposes a design that seeks to enhance mobility and promote autonomy. Methods : This study conducted observational research and interviews with 13 individuals aged 65 and older from May to June 2024. The interview questions were developed based on physical and psychological analysis elements identified in previous studies, as well as the seven principles of universal design. The data collected was analyzed, and the design improvement process was carried out using the five-stage model of design thinking from d.school. Results : Based on the participants' real-life experiences, as well as their physical and psychological discomforts and sources of anxiety, this study applied the seven principles of universal design to the walker and conducted the design thinking process. By following the stages of 'Empathize', 'Define', 'Ideate', 'Prototype', and 'Test' the study derived conclusions and suggested directions for design improvement in walker development. The analysis prioritized reducing shoulder and wrist strain through adjustments in handle angles and brake structure, while enhancing psychological well-being through the inclusion of safe storage space and an intuitive folding mechanism. A design proposal reflecting these improvements was presented. Conclusion: This study emphasizes the necessity of walker designs that reflect the specific needs of older adults in preparation for the transition into a super-aged society. By combining the principles of universal design with a user-centered design thinking process, a walker was developed that allows older adults to experience both physical and psychological comfort. The study highlights the importance of design approaches that consider not only the physical comfort but also the psychological well-being of older adults. It further suggests the need for designs that incorporate the real-world needs of users in the development of future products for the aging population.
