A first-aid kiosk connecting item search, guided questions, safety information, and a physical service.
Opportunity
At entertainment venues, finding supplies can mean leaving a crowd, locating a medical tent, and waiting. Research with approximately 30 participants informed a service for visitors who know what they need and those who need guidance. Interview insights emphasized clear product instructions, emergency assistance, and item search. Field observations at Petco Park explored entrances, exits, and other potential kiosk locations.
System
I led UI/UX work within the team. The physical prototype connects the touchscreen with an emergency button, cash and contactless payment touchpoints, and a dispensing bay. Form studies explored the enclosure before the full-scale build. Screen and enclosure belong to one journey: understand the route, select an item, review information, then collect supplies.
Flow
Known-item search and a guided questionnaire offer different starting points. The questionnaire asks about responsiveness before symptoms and recommendations. Search results allow visitors to inspect product information or add items to a cart. Both routes lead toward checkout.
WelcomeThe welcome screen provides one entry point into the service.
Decisions
Testing identified three priorities for the next iteration: simplify emergency questions, make symptom choices easier to distinguish, and provide richer item information. These findings guide the proposed revisions below.
Decision / Why: The flow includes a responsiveness question before product recommendations.
Evidence: Testers were unclear about emergency actions. Double-negative wording caused confusion; the team recommended simpler questions and reordered hierarchy.
Decision / Why: The screen requires acknowledgement of dosage and allergy information before payment.
Decision / Why: Visitors can choose a direct item route or a questionnaire instead of following one path.
Evidence: Search was described as quick to use. The questionnaire could feel long and stressful; symptom choices were difficult to distinguish.
Outcome
More than 10 users tested the connected experience. Search was described as quick to use, while the questionnaire exposed confusing wording, unclear emergency actions, and difficult-to-distinguish symptoms. Item descriptions also needed more detail. The next iteration would reorder questions, clarify emergency routing, simplify symptom choices, and expand product information, followed by another round of testing.
As project lead and UI/UX designer on a four-person team, I led the interface work connecting item search, guided questions, review, and checkout with the physical kiosk experience.
The testing findings made the next design priorities clear: question wording, distinguishable symptom choices, and explicit emergency actions matter as much as connecting the screens. The proposed revisions still need implementation and another round of testing.
