Continuous patient surveillance for faster intervention.
Standard vital-sign checks occur every 4–6 hours, leaving gaps that risk delayed detection of critical events. Sotera required a system that delivers high-fidelity, wireless monitoring to identify early signs of sepsis and cardiorespiratory decline while preserving patient mobility. RKS addressed usability, reliability, and emotional trust to help drive earlier intervention and improved outcomes.
Research Insights & Discovery
Key Outputs
- User Personas
- Psycho-Aesthetics® 2.0 Map
- Benchmarking
- Opportunity Areas & Design Criteria
- How We Used Psycho-Aesthetics™ to Identify Unique Opportunities in the Project.
RKS conducted in-depth field studies in hospital wards with physicians and nurses, analyzing current pain points: intermittent monitoring, alarm fatigue, device usability, and clinical workflow interruption. Through Psycho‑Aesthetics®, we positioned ViSi Mobile within the empowerment/empathy quadrant, focusing on trust, continuous oversight, and patient dignity.
How We Used Psycho-Aesthetics™ to Identify Unique Opportunities in the Project.
Using our proprietary Psycho-Aesthetics® 2.0 framework, we conducted in-depth interviews and ethnographic observation in diverse lab settings. We identified key emotional and usability pain points, such as intimidation with complex interfaces, workspace clutter, and trust in precision. These insights guided both the form and interface strategy, ensuring approachability and confidence in operation.
Industrial Design Concept Development
Key Outputs
- Form Factor Concepts
- CMF Strategy
- Refined Industrial Design Language
Our team designed a patient-worn module with ergonomic shape, secure attachment, and lightweight materials. The wearable form enables continuous data capture without restricting movement, featuring visual status indicators and streamlined form for bedside handling.
UI/UX Design Development
Key Outputs
- Information Architecture
- Touchscreen Interface Design
- Custom Iconography & Visual System
- Interactive Prototypes
We created intuitive UI for both the wearable device and web dashboards. Interfaces prioritize rapid access to vital-sign trends, alerts, and analytics, minimizing cognitive load and enabling swift clinical decisions. Touchscreens and web platforms were tailored to nurse workflow, physician rounds, and telemetry integration.
Product Engineering & Development
Key Outputs
- Engineering Evaluation Prototypes
- Tolerance Analysis & DFM Refinements
- Validation Reports
RKS collaborated closely with engineering partners to integrate sensors, wireless transmission, and data analytics into a robust system. Prototyping cycles validated durability, battery life, fit, and network interoperability.
Key Outcomes and Results
Key Accomplishments
- Over 35,000 patients monitored across 45 hospitals, amassing over 1 million hours of continuous vital-sign data.
- Early FDA clearance and broad clinical deployments validated the system’s usability
RKS Design’s end‑to‑end collaboration on Sotera’s ViSi Mobile represents a design-enabled breakthrough in patient surveillance. By unifying emotional insight, form-based ergonomics, intuitive interface, and reliable engineering, we helped transform intermittent vital-sign checks into continuous, wearable monitoring, empowering clinicians to act earlier, with confidence, and without compromising patient mobility.
