To evaluate a newly developed integrated digital prosthetic, the COGKNOW Day Navigator (CDN), to support persons with mild dementia in their daily lives, with memory, social contacts, daily activities and safety.
A user participatory method was applied in the development process, which consisted of three iterative 1-year cycles with field tests in Amsterdam, Belfast and Luleå. In the successive cycles 16, 14 and 12 persons with dementia and their carers participated. Data on usability were collected by means of interviews, observations, questionnaires, logging and diaries. The CDN prototype consists of a touch screen, a mobile device, sensors and actuators.
The evaluation showed that persons with dementia and carers valued the CDN overall as user-friendly and useful. Conclusions regarding the effectiveness of the system in daily life were limited due to insufficient duration of the testing period caused by delays in development and some instability of the final prototype.
With the suggested adaptations, the CDN is expected to be a useful tool for supporting community-dwelling persons with mild dementia and their carers.
评估新开发的集成数字义肢 COGKNOW Day Navigator（CDN），以支持轻度痴呆症患者的日常生活，包括记忆、社交联系、日常活动和安全。
在开发过程中采用了用户参与的方法，该方法包括在阿姆斯特丹、贝尔法斯特和吕勒奥进行的三个为期 1 年的迭代现场测试。在连续的三个周期中，共有 16 名、14 名和 12 名痴呆症患者及其照顾者参与。通过访谈、观察、问卷调查、记录和日记收集了可用性数据。CDN 原型由触摸屏、移动设备、传感器和执行器组成。
评估结果表明，痴呆症患者和照顾者总体上认为 CDN 易于使用且有用。由于开发延迟和最终原型的一些不稳定性导致测试期不够长，因此对系统在日常生活中的有效性的结论有限。
经过建议的调整，CDN 有望成为支持轻度痴呆症患者及其照顾者在社区生活的有用工具。
