Developing novel visual messages for a video screen hand sanitizer: a co-design study with students

This paper reports on the results of a series of co-design workshops devised to generate new messaging ideas for a novel hand sanitizer unit that features a video screen and feedback system. Students of different nationalities, ages and genders were involved in the process either to prime design sessions, or devise/evaluate new ideas for the screen to display in a university setting. The project aimed not only to produce animated designs for subsequent testing but also to elicit key preferences for hand hygiene message tone, content and visual appearance. Research findings revealed a clear preference in the student community for positive, caring and playful approaches to hand hygiene messaging in contrast to many messaging approaches featured in previous studies. In terms of visual approach, students expressed a preference for colourful illustrations rather than photographs or word-based messages. The paper highlights some particularly rich ideas developed to exploit the novelty of the device, such as specific animated sequences or immediate visual rewards of internet memes as ways to engage the student audience. Co-design proved valuable in devising new insights for the hygiene communication community.
