| Abstract |
| We have successfully digitalized various aspects of our lives for greater convenience. Unfortunately, the elderly are often not the beneficiary of digitalization. Older people experience sensitivity loss and thus cognitive decline. To share the benefit of digitalization with the elderly, we need to develop products that understand the challenges of aging. The study intends to identify the ways to improve the usability of digital products for elderly users, with particular emphasis on feedback and feed-forward. To accomplish the purpose, this article adopts a context-focused approach that focuses on interview and participatory observation, rather than a quantitative approach that focuses on the size of shape and sound. Since the elderly have low usability as a result of sensitivity loss and cognitive decline, the subjects are observed in a holistic manner. Four different digital products are used for the observations. Based on the observations, this study 1) evaluates the performance of different feedback and feedforward and 2) analyzes the relationship between performance and issues of aging and identify the characteristics of the most effective feedback and feedforward. |
