Research on Facts
Shadowing and User Interviews. I spoke to elderly people and their families. Here are few insights from the interviews that validated our assumptions and helped us understand the user. The first 3 are the elderly personas and the next 3 are the family members of the elderly.
System Diagram Based on Research Insights
Interacting with users and empathizing with them helped us in formulating our linkage system diagram. We defined that the elderly would need an efficient less tech savvy device and the family members would need a mobile app which has device compatible features which can be quickly accessed. We strive to solve some of the problems mentioned in the above user quotes.
Information Architecture for the Mobile App
The wireframes depict the entire flow and navigation of the mobile app.
Key Interactions addressing the most prominent user activities on the mobile app
The wearable device has a wrist strap, micro USB charging port, 3.5mm audio port, and an emergency alert button which immediately notifies family members and caregivers with a single press. Additionally, it has a fall detection feature which automatically detects the fall and notifies the family members and caregivers. The wearable continuously monitors the pulse rate. Mobile app receives hourly summary of the pulse rate, and also receives alert when the pulse rate is outside the normal range.
Mobile App + Wearable Device
The upcoming reminders, alerts, messages on the dashboard of the app show up on the wearable screen as transient reminders. The reminders set on the mobile app show up on the wearable as audio visual notifications. The family members and elderly can chat using the messages feature. Messages sent from the mobile app can be heard or read on the wearable. Audio reply can be sent from the wearable.
The wearable can be pinned to clothing, attached to a walking stick wheelchair or can be worn on the hand. It has an elastic strap and a simple magnetic attachment mechanism.
