In this interdisciplinary essay, Jef Raskin drew unexpected parallels between nursing theory and interface design. Both fields, he argued, share a fundamental concern with understanding and responding to the needs of the person being served — the patient in nursing, the user in computing.
The Connection
Nursing theory emphasizes the importance of understanding the whole patient — their physical condition, mental state, emotional needs, and environment. Similarly, Raskin argued that interface design must account for the whole user: their cognitive limitations, their goals, their level of expertise, and the context in which they work.
Shared Principles
- Do no harm — both disciplines prioritize avoiding negative outcomes, whether medical complications or data loss
- Evidence-based practice — both fields benefit from grounding decisions in measured outcomes rather than tradition or intuition
- Patient/User autonomy — the professional’s role is to empower the person they serve, not to impose control
- Holistic assessment — effective practice requires understanding the complete context, not just the immediate symptom or task
Significance
This essay exemplified Raskin’s characteristic approach of finding insights in unexpected fields and applying them to interface design. His willingness to look beyond computer science for design principles was one of the qualities that distinguished his work from mainstream HCI research.
