Field Deployment

A research evaluation method where a system or tool is released to real users in their natural environments rather than being tested only in controlled laboratory settings. In accessibility research, field deployments are important because they reveal how assistive technologies perform across diverse real-world conditions — different websites, screen readers, operating systems, and usage contexts that cannot be fully replicated in a lab. Field deployments may involve publishing browser extensions to the Chrome Web Store, hosting web applications on public servers, or distributing tools through disability organizations. They are typically followed by case studies, diary studies, or surveys to gather feedback on real-world utility. Field deployments complement controlled user studies by providing ecological validity at the expense of experimental control.
