Human Intelligence Task

A unit of work on a crowdsourcing platform, particularly Amazon Mechanical Turk, that requires human judgment to complete. HITs typically involve tasks that are difficult for computers but straightforward for humans, such as image labeling, transcription, content moderation, or survey completion. In accessibility research, HITs have been studied both as a source of accessible content (e.g., generating image descriptions) and as potential employment for people with disabilities, with findings suggesting that task design — including simplification and step-by-step decomposition — is critical for making HITs accessible to workers with cognitive disabilities.
