How should it work for the people using it?
Clinical workflow, interaction design, comfort, and accessibility under real conditions of use.
Unsolved engineering problems at this stage, each linked to work documenting the difficulty.
Visual realism has advanced far faster than touch. Without convincing resistance and texture, a simulator teaches the sequence of a procedure but not the feel of it, which is much of the skill.
Multi-week self-directed therapy works only if patients keep going after the first fortnight, and drop-off is the usual outcome.
Higher fidelity costs more and is assumed to teach better, but which cues change behaviour — and which are decoration — is rarely tested.
The events that most need practice — outbreaks, mass casualties, rare deteriorations — are precisely the ones a rota cannot produce on demand.
Competence is still largely judged by observation, which is expensive, inconsistent between assessors, and hard to schedule.
Moving therapy into the home removes travel but also removes the clinician, leaving technique uncorrected and progress unmeasured.
Demand for responders spikes exactly when trainers are least available, and conventional courses do not scale to meet it.
