Humans have become exponentially more productive at work due to advances in technology. However, these advances are spurred by a desire to increase output, often without considering wellbeing. Consequently, modern knowledge workers (i.e., occupations primarily involving applying information rather than physical tasks) experience unhealthy conditions such as sedentary behavior, social isolation, and excessive screen time. The consequences of chronic exposure to such conditions can be drastic for users' mental and physical wellbeing. Even when users make efforts to increase healthy behaviors in the workplace, such as by installing standing desks, uptake remains low in practice due to the intention-behavior gap. Technology designers have an opportunity to combat the negative effects of the modern workplace, but they should not degrade productivity for their solutions to be accepted in industrial practice.
Thus, the problem is two-fold: (1) the modern office prioritizes productivity at the expense of wellbeing, and (2) users have difficulty changing their behaviors even when healthy interventions are available. These factors reveal a spectrum of influence connected to both if and how people are motivated to change their behaviors. This thesis navigates along this spectrum by conducting studies and evaluating prototypical systems to build an understanding of this motivation. Consequently, this thesis outlines a vision for a healthy future of work through two approaches. First, we investigate how to design technology to make healthy ways of working a more attractive choice for users. Second, we explore active behavior change technologies that aim to overcome the intention-behavior gap and ethically nudge users to behave according to their own goals.
In the first series of explorations, we investigate technology that inspires users to incorporate movement in the workplace. The works in this section use passive behavior change approaches, aiming to make movement an attractive option that users will choose of their own volition. We used ethnographic methods to understand the needs of users who regularly integrate physical activity into their work routines. Drawing from this knowledge, we developed a tangible prototype to explore technology-supported walking meetings. Finally, we explored using physical exertion as a design element to generate mindful experiences. Overall, these investigations provide a new understanding of how technology can seamlessly integrate physical activity into work routines while creating positive user experiences.
Next, we explore active approaches that nudge users to act in alignment with their own goals. We designed and implemented functional prototypes and conducted mixed-methods evaluations on interventions to increase movement, foster social connectedness, and manage excessive screentime, all of which are issues in the modern office. To increase ecological validity, we conducted three of the studies in the field, including one large-scale longitudinal study. These investigations provide insights into how technology can support users in overcoming intention-behavior gaps to achieve their own behavior goals in the real world.
Based on our investigations, we propose a design framework for behavior change technologies that promote a healthy workplace. The framework draws from related work and incorporates theoretical concepts from physiology and nudge theory. We designed the framework to be beneficial for researchers and technology designers in creating behavior change technologies.
In all, this thesis contributes the following: (1) prototypical systems to facilitate improvements in physical activity, mindful screen time, and social interactions, (2) field evaluations of workplace behavior change technologies, (3) an actionable design framework highlighting important design dimensions and categorizing literature for future developers of ethical behavior change technologies, and (4) a reflection on ethical behavior change. Finally, we discuss open challenges for the field and deploying research in practice. This thesis demonstrates the potential for technology to support healthier workplaces without sacrificing productivity by providing concrete solutions and ecologically validated field evaluations. By advocating for the integration of wellbeing principles into workplace design and emphasizing user-centered approaches to behavior change technologies, our work lays the groundwork for creating healthier and more productive workplaces in the future.
