Towards smartwatch-driven just-in-time adaptive interventions (JITAI) for building occupants

Abstract

Building occupants are complex in the aspects of the indoor environment that satisfies them. Thermal comfort-driven systems control, office floor plan design, and lighting or acoustics considerations are all driven by conventional understandings of how occupants use spaces. Building operators rely on the use of smart system control; however, these approaches ignore the occupants' ability to make decisions that influence their comfort, satisfaction, and productivity. The future-of-work paradigm shift will introduce more flexibility and behavior-driven opportunities for occupants. The emerging just-in-time adaptive intervention (JITAI) concept is gaining momentum in fields such as mobile health as a means of influencing behavior. This paper outlines a novel methodology using smartwatch-based JITAI combined with micro-ecological momentary assessments (EMA) for field-based data collection and occupant behavior interventions in field-based scenarios. A proof-of-concept deployment of a single user of the methodology is illustrated to set the stage for future data collection. This framework can provide the foundation for techniques to enhance the future of work through behavioral interventions in the built environment.
