Key factors in the design of next generation portable supporting devices for elderly adults

Abstract

Purpose: This study began with an analysis of the lifestyle trends of elderly adults in Taiwan. We found that the elderly believe in 'active aging', and their core values gradually change from family focus to connection with people and planning their 'second lives'. Based on secondary sources, elderly adults enjoy going outdoors and exercising more than in previous generations. Walking and mountain climbing are the most popular activities. We found five common lifestyle patterns among the elderly: (i) joining community activities, (ii) enjoying family life, (iii) interacting with friends, (iv) watching and participating in recreational sports, and (v) participating in charitable religious activities. Physiological aging becomes increasingly apparent as people age, for example, knee pain while walking and mountain climbing, an inability to sustain exercise for long periods, and more time needed to recover from body fatigue. In light of this, we initiated plans for a device with which older adults can extend their activity time. This device should be lightweight and easy to use and carry. We benchmarked commercial products and did not find suitable products. Therefore, this study presents the planning and development of 'next generation portable supporting devices'. Method: Questionnaires were distributed to older adults participating in community activities in order to better understand the behavioral patterns in the everyday lives of 'active' older adults. Three lead users were interviewed to analyze how the elderly use commercial assistive devices. According to the questionnaire results and analysis, some key factors were found for the design of next generation portable supporting devices for older adults. Results & Discussion: Table 1 shows the results of the analysis in Need- Solution-Differentiation-Benefit. The key factors for the design were derived from the questionnaire results and include: (i) The device appears safe when it is being used. Safety features include high durability and an absence of sharp edges. (ii) The device is lightweight and portable, can be easily folded for storage, and is easily adjustable. (iii) The device has a stylish appearance, but is not conspicuous. In addition, it can be used to call the hospital, police, or home in emergencies. Based on the analysis, we generated seven design concepts for next generation portable supporting devices for elderly adults. We are in the process of developing the concepts into a commercial product that is different from existing commercial products and has more advanced technology and a more innovative design concept.
