Defining the problem
Notice
Disclaimer
All of the concept, research, and original drawings created for the Oculus Kiosk is owned by Camille Dorset (MS, Applied Health Informatics at Fordham University). The Oculus Kiosk was a collaboration project between Camille Dorset (owner of the Oculus Kiosk), John Chelsom (CEO of Seven Informatics Ltd.), and myself (a contract UX Designer).
The Problem
Seven Informatics Ltd., a research consultancy, recently explored integrating cityEHR into ophthalmology triage. A student researcher, also an SME and former ophthalmology MOA, created proof-of-concept sketches based on clinic care pathways. My task was to refine these sketches into an accessible and UX-driven prototype that would accommodate ophthalmology patients of all backgrounds.
The Solution
Design Decisions
Improvement 01
Inspired by an SME’s anecdote of a patient without fingers, the Oculus Kiosk prioritizes larger touch targets for accessibility. Digitizing intake removes the struggle of holding a pencil for physically or cognitively impaired patients. With oversized buttons exceeding WCAG 2.1’s 44x44 px standard, even those with limited dexterity can navigate the interface with ease.
Improvement 02
Intuitive Iconography
An SME from a New York City ophthalmology clinic stressed the need for clear visuals to simplify complex medical jargon. Since most patients struggle with clinical terms, large images and icons aid recognition, especially for the visually impaired. Condition names were simplified, and visuals were designed for key medical conditions.
Usability testing showed 80% of participants used icons as helpful secondary aids, using them to confirm their choice after first referring to the text. Icons were placed on a dark yellow (#FFB81C) background for contrast, avoiding red-green combinations to accommodate patients with deuteranopia.
Improvement 03
High Contrast UI
To enhance accessibility, I tested the Oculus Kiosk’s color palette with a color-blind peer and incorporated their feedback. I also referenced WCAG 2.1 contrast guidelines to ensure high-contrast colors that accommodate all users, including those with visual impairments like color blindness.
Improvement 04
Readability
Sans-Serif. I used two sans-serif fonts—Cal Sans for titles and buttons, and Manrope for labels and body text—to enhance readability by eliminating extra strokes.
Text Size. Larger, bolded text with wider line spacing improves glanceability and lexical decision-making (NNG). Following APH ConnectCenter guidelines, text is at least 18pt (24px) for low-vision users.
Sentence Case. Using sentence case improves legibility by creating distinct word shapes, aiding those with visual impairments. Unlike title case, which appears block-like, sentence case enhances readability—an approach supported by Google's Material Design.
Improvement 05
Ergonomic Hardware Experience
40% of participants preferred scanning their health insurance card over manual entry, improving accessibility for physically impaired patients. This feature requires integrating a card scanner into the kiosk or tablet, along with an intuitive onboarding experience to guide users through the process.
The instructional graphics should be self-explanatory and provide users with system feedback and progress of their card scan. There are 3 distinct phases with 2 edge case for statuses:
Enter your card
Scanning your card
Remove your card
Scan success
Card error
Results & Next Steps
Impact
Results
Our conference paper 'A Health Records Kiosk, Using an Ontology-Based Information Architecture' (J. Chelsom, C. Dorset, W. Lee, 2025) was published by Springer Nature as part of the book 'Health Informatics and Medical Systems and Biomedical Engineering'; a collection of papers submitted for the HIMS 2024 Conference.
Future
Develop the Oculus Kiosk
The Oculus Kiosk is currently being developed and it will soon be prepared for deployment to real-world clinics. The Oculus Kiosk uses the cityEHR created by Seven Informatics Limited as a backbone for its back-end.
Deploy to a Real-World Clinic
Once the Oculus Kiosk is fully developed, we have plans of piloting it in either the New York clinic our SME works at or in Oxford, close to where Seven Informatics Limited operates. Though it was originally designed for an American healthcare system, depending on where we decide to ship, we will make slight adjustments to the workflow.
Pilot Testing
Once we have implemented and deployed the Oculus Kiosk to a real-world clinic, we plan on doing a second round of testing with both patients along with care providers and MOAs and continue to iterate and improve the user experience.
