This is particularly pronounced among office workers. Sitting breaks can attenuate some of these detrimental health effects. Thus, our goal was to design a persuasive system to prompt frequent sitting breaks in the office. With our system we want to address two key issues of existing approaches: low compliance due to lack of motivation, and user annoyance with frequent prompts. Based on a literature review, we developed four design concepts each using a different prompt modality (appearance, audio, light, movement) and evaluated them qualitatively by conducting a focus group interview with a panel of workplace health management experts (N=5) and quantitatively in an explorative online study with our target demographic (N=39) rating the concepts’ perceived persuasiveness and obtrusiveness. Based on our findings, we derive design implications for researchers and practitioners, and demonstrate their technical feasibility by providing a proof-of-concept implementation.encalm technologyofficepersuasive technologysedentary behaviorText/Conference Paper10.1145/3670653.3670681
