How We Used Psycho-Aesthetics™ to Identify Unique Opportunities in the Project.

The Hamilton HF90 was developed to deliver high-flow oxygen therapy in a compact, intuitive system tailored for modern clinical environments. RKS Design partnered with Hamilton Medical to translate complex respiratory technology into a clear, approachable user experience—balancing performance, ergonomics, and visual simplicity. Guided by Psycho-Aesthetics®, the HF90’s form, interface, and interaction design reduce cognitive load for clinicians while supporting accurate, efficient care delivery across acute and non-acute settings.

Ethnographic research grounded the HF90 in real-world clinical environments, revealing how respiratory therapists and clinicians interact with high-flow therapy systems throughout a shift. Observations focused on setup, adjustment, cleaning, and mobility uncovered friction points and behavioral patterns that informed usability, ergonomics, and interface clarity—ensuring the HF90 integrates seamlessly into daily clinical practice.

Ethnographic Research

KEY OUTPUTS

In-context observation of clinicians in respiratory care settings
Workflow mapping across setup, use, and maintenance
Identification of usability pain points and opportunity areas
Behavioral insights informing ergonomic and interface decisions
A collage of photos shows people assembling, adjusting, and testing medical ventilators and related equipment in a clinical setting, along with labeled ventilator diagrams and prototypes on desks.
RKS provided innovation consulting to align Hamilton Medical’s technical capabilities with unmet clinical needs and future-focused care models. Strategic guidance ensured the HF90 addressed not only functional performance requirements but also differentiation through usability, form factor, and system integration—supporting adoption across diverse care settings.

Prototyping for the Hamilton HF90 centered on a series of appearance model iterations used to refine form, proportion, and visual clarity. These models allowed the team to evaluate how the device would be perceived in clinical environments, balancing approachability with precision and performance. Through iterative refinement, design decisions around scale, surface transitions, component integration, and overall presence were tested and evolved—ensuring the final design communicated confidence, cleanliness, and clinical reliability before advancing to production.

Prototyping

KEY OUTPUTS

Multiple appearance model iterations exploring form, scale, and proportion
Refinement of surface geometry and transitions for visual clarity
Evaluation of component integration and overall product architecture
Validation of clinical presence and approachability through physical models
