One possible but not yet very established input method is eye gaze. The present article investigates a gaze-controlled interface in the context of manual assembly tasks, where it provides a language-free and at the same time hands-free input alternative. To this end, we implemented a gaze-controlled instruction prototype and compared its efficiency, usability, and user experience to that of an established paper manual. Both instruction forms were assessed on subjective measures (NASA-TLX, UEQ, and USE) as well as on an objective measure (assembly time). Albeit being prototypical and novel to the participants, the usability of the gaze-based instruction form was at least comparable to that of the paper manual and on some scales even better. Further, the gaze-based interface yielded similar assembly times and was rated preferable in terms of user experience. Taken together, our results suggest that gaze-based instructions can be a valuable alternative to previously used instruction forms in the work context.enGaze-controlled InterfaceManual Assembly TaskUsabilityUXText/Conference Paper10.1145/3543758.3547537
