✦ OVERVIEW
Designing for the emotional cost of waiting
CalmER is a mobile companion app for older adults during ER waits, built for the Michigan Tech Innovation Jam in 6 weeks. The average ER wait is 6.5+ hours — for seniors who arrive alone, that time is filled with confusion, anxiety, and isolation. We weren't trying to shorten the wait. We were designing to reduce its emotional cost.
The problem we focused on
- • 33 million senior ER visits/year — often alone
- • No clear updates → anxiety compounds over time
- • "Left without being seen" rate doubled to 2.1%
- • Staff too busy to provide reassurance
Our design constraints
- • Can't predict or control medical timelines
- • AI cannot give medical advice
- • Must not add burden to already-stretched staff
- • Accessible for seniors with vision/motor impairments
✦ RESEARCH
What shaped the design
Given the 6-week timeline, we combined secondary literature (ACEP data, hospital satisfaction studies), expert consultation with a team member's medical contacts, and competitive analysis of existing patient apps — synthesized via affinity mapping.
Reassurance matters more than information
Older adults don't want a data dashboard — they need a gentle reminder they haven't been forgotten.
Uncertainty is the real stressor, not the wait itself
Not knowing what's coming next creates more anxiety than the wait time. Transparency is therapeutic.
Seeing a familiar face outperforms any status update
Family connection — even remote — significantly reduces isolation. This shaped our One-tap Family Link feature.
✦ DESIGN FRAMEWORK
The 3C Framework: Clarity · Calmness · Connection
Clarity
Stage-based progress instead of unpredictable countdowns. Clear language at every step.
"When I know what's next, I feel less afraid."
Calmness
Soft colors, breathing guides, and an AI companion that supports — not advises medically.
"It feels like someone is there with me."
Connection
One-tap family video call. Real-time status updates for remote family members.
"I can see my son's face. That helps more than anything."
✦ KEY FEATURES
Four features, one goal: make waiting feel human
AI Emotional Companion
Calming conversations, breathing guides, medical term explanations — voice or text.
Smart Hospital Sync
Live triage updates, stage-based timeline, simple language explanations of what's next.
Instant Family Link
One-tap video call + automatic status sharing so remote family stays informed.
Resource Hub
Breathing exercises, ER FAQs, social worker access — turning wait time into grounding time.

Health Track Top 3 — Innovation Jam
CalmER was recognised as a Top 3 project in the Health track at the Michigan Tech Innovation Jam. The judges highlighted the emotional design approach — specifically the 3C framework and the decision to prioritise video calling over text updates — as standout contributions.

✦ REFLECTION
What I learned
This project changed how I think about emotional design — it's not decoration, it's a functional requirement when users are scared or in pain. Three decisions stood out:
Stage-based timeline over countdown
"Triage Complete → Lab Results Pending" reduces anxiety more than "est. 2 hours" — predictable process beats unpredictable time.
AI as companion, not doctor
Positioning the AI as emotional support rather than medical advisor maintained user trust while keeping us within safe, honest boundaries.
Video over messaging
Seeing a familiar face has disproportionate emotional impact compared to text updates — so we built one-tap video instead of a status dashboard.
Next step: usability testing with actual seniors in ER waiting rooms, and piloting the AI companion with real hospital system integration.
