Switching input modalities in microtask crowdsourcing does not affect worker accuracy or perceived cognitive load but influences task completion time; ergonomically informed gestures can integrate effectively without impacting worker experiences.
Methods: A between-subjects study was conducted across 16 experimental conditions with varying input modality sequences to assess impacts on task outcomes and worker experiences.
Key Findings: Effect of switching input modalities on task completion time, accuracy, and perceived cognitive load among crowd workers.
