In-Situ Deployment

A research methodology in which a functional prototype or product is installed on participants' own devices and used in their everyday environment over days, weeks, or months, rather than in a controlled laboratory session. In-situ deployments are especially valuable for accessibility research because they surface how disabled users integrate (or abandon) new tools within existing routines, fatigue budgets, and support networks — insights unavailable from short demo sessions. Typically triangulate behavioural logs with semi-structured exit interviews and experience sampling.
