Abstract

Challenges faced by healthcare services for visually impaired persons are becoming increasingly complex. There is a lack of interventions for people in the transitional stage of blindness (the process of vision loss). The present study described a human-centred design approach to help visually impaired persons to better adapt to the transitional stage. Fifteen visually impaired persons and their relatives were interviewed to understand user behaviors and need in the empathize phase. After discussing with stakeholders, we defined user personas and problem statements. In the ideate phase, a healthcare service, including a self-training space and a health management app, was developed to help visually impaired persons to train their auditory, tactile, and directional walking abilities in different environments through sensory compensation. The results showed a high usability score, which revealed how the human-centred design approach could help visually impaired persons to train themselves during the transitional stage effectively.

摘要

视障人士的医疗保健服务面临的挑战变得越来越复杂。对于处于失明过渡阶段（视力丧失过程）的人缺乏干预措施。本研究描述了一种以人为本的设计方法，以帮助视障人士更好地适应过渡阶段。采访了 15 名视障人士及其亲属，以了解用户在共情阶段的行为和需求。在与利益相关者讨论后，我们定义了用户角色和问题陈述。在构思阶段，开发了包括自我训练空间和健康管理应用程序在内的医疗保健服务，通过感官补偿帮助视障人士训练他们在不同环境下的听觉、触觉和定向行走能力。
