Crowdsourcing Accessibility

The practice of using distributed groups of people, often through online platforms, to collect, label, or improve accessibility-related information at scale. Examples include using crowd workers to audit bus stop landmarks via Google Street View, label images for alt text, assess sidewalk accessibility, or transcribe audio content. Crowdsourcing accessibility leverages the scalability of human computation to address information gaps that disproportionately affect people with disabilities, complementing automated approaches with human judgment and perception.
