I proposed a system that supports patients with mild dementia to sustain healthy daily routines and independently perform activities that fit their present cognitive abilities. The proposed system helps the patient and their family caregivers structure daily activities and manage these tasks together with professional consultation.
In designing the system, I assumed four stakeholders: patient, family caregivers, occupational therapists, and doctors. These stakeholders act within a practice framework that consists of the following phases: Planning, Initiating, Performing, and Evaluation.
Specifically, the users devise a plan on patient’s daily activities through defining ‘when to do’ and ‘how to do’. Afterward the patient receives a cue from the system suggesting that they start a scheduled activity. While the patient is performing the activity, the system provides prompts corresponding to the present step, by which the patient can complete the task with less cognitive demand and produce fewer errors as a result. The users assess patients’ initiation and performance data to modify the current plan. The below table details each user group's involvement within the framework.
I developed interaction design of the system as illustrated below. View the full storyboard [PDF].
