Choi, Woohyeok has Ph.d in Industrial and System Engineering (Graduate School of Knowledge Service Engineering), Korea Advanced Institute of Science and Technology (KAIST). My research interest focuses on building interactive applications that promote physical health, including exertion-based games, physical activity promotion at work, and mobile-based health intervention. Throughout my studies, I have had a variety of expertise: front-/back-end development, hardware prototyping, machine learning, and statistical analysis.

Even people perform a sufficient amount of physical activities, uninterrupted sedentary behavior would cause increased waist circumference. This work explores how to provide Just-in-Time support for prevention of prolonged sedentary behavior, including (1) when to deliver JIT support, and (2) how to…

As prolonged sedentary behavior causes early mortality, there has been increasing interest in active workstations, which allow workers to simultaneously perform both office tasks and physical activities; but, it is unknown how office workers actually use in real world. This research is the first…

Group fitness is one of the most representative social exercises and includes any forms of fitness exercises performed by a group of people led by an instructor. By leveraging unique characteristics of group fitness, this work explores how to design social exergames which provide similar experience…
