Abstract:The One Health Hub, a question and answer website for the general public and healthcare professionals’ questions about zoonoses, was usability tested by the general public. 37 members of the general public participated in the One Health Hub usability tests, carried out in a mobile test environment, the Experivan. The usability test involved execution of six scenario based tasks, a User Experience Questionnaire and a retrospective think aloud sessions with either video- or gaze video cues. The identified usability problems, effective user interaction, and added value of a gaze cue in usability testing were analysed. The One Health Hub’s user experience was positively evaluated by the participants who identified 149 usability problems whilst interacting with the One Health Hub with a success rate of 61.3%. The gaze video cue evoked identification of more layout- and total number of usability problems with a higher severity level, verbalisation of more words and manipulative and cognitive operational comments, as compared to a video cue. A prototype was developed with implemented recommendations to enhance the One Health Hub’s usability. The overall consistency and navigational elements of the One Health Hub should be improved to ensure faster and more successful goal achievement by users.
