CareMate Emergency Response Platform
CareMate is a healthcare emergency response platform designed for elderly users and the ecosystem that supports them. The system enables elders to trigger emergency assistance while coordinating caregivers, emergency officers, response centers, ambulance services, and sponsors through a single structured workflow.
I led the UX and service design across the elder facing mobile app and supporting operational interfaces, focusing on accessibility, clarity, and coordination during high stress situations where speed and trust are critical.

Challenge
Elder Accessibility
Elderly users faced difficulty interacting with complex mobile interfaces, small touch targets, and unclear feedback during emergencies, leading to hesitation and failed actions when help was needed most.
Multi Stakeholder Coordination
Emergency events required seamless coordination across multiple independent actors with different goals, tools, and response times. Existing workflows were fragmented and heavily manual.
High Stress Decision Making
Emergency scenarios left no room for ambiguity. Delays, unclear system feedback, or missed notifications directly impacted safety outcomes.
Solution
Emergency First Interaction Model
Designed a simplified emergency trigger optimized for elderly motor and cognitive limitations, providing clear confirmation, immediate feedback, and minimal steps under pressure.
Service Design Across Roles
Mapped and designed end to end service flows connecting elders, emergency officers, central response units, ambulance networks, and sponsors, ensuring each actor received the right information at the right time.
Progressive Information Disclosure
Structured information delivery so responders saw critical data first, with secondary details revealed only when needed, reducing cognitive load during emergencies.
Accessibility Driven Design
Applied WCAG aligned contrast, typography, and interaction patterns to support aging users, low vision scenarios, and high stress usage conditions.
Impact
Increased Elder Confidence
Usability testing showed improved confidence and reduced hesitation among elder users when triggering emergency assistance.
Faster Response Coordination
Clear role based workflows reduced confusion and handoff delays between response teams during simulated emergency scenarios.
Measurable Satisfaction Improvement
Post testing showed a 30 percent increase in elder user satisfaction after addressing accessibility, clarity, and trust gaps in the experience.
