Prolonged sedentary behavior is a common issue for the modern population. For office workers, one of the current economic approaches of dealing with prolonged sedentary behavior is to deliver prompts to trigger themselves to take a walk. However, researchers found that more than half of the prompts sent in the workplaces failed to trigger a break, and the two major reasons given were ignorance and refusal. Moreover, successfully functioning to interrupt recipients, the prompts may be too interrupting and annoying to the recipients, leading to future abandonment of the function or app. This study wants to investigate a way to improve user experience while keeping the prompts functional. It proposes to use humor in the content of prompts to investigates how humor can influence behavioral intention and perceived interruption. We conducted an Amazon Mechanical Turk scenario-based survey with 114 participants. This study found the use of humor triggers the behavioral intention of taking a break from prolonged sitting in the workplaces more than the prompts without humor. The findings suggest that a humorous prompt, if appreciated by the recipient, may be an effective method of getting workers to move.
