This thesis aims to create an easy to play exergame that can be used by office workers in theirday-to-day work to battle the long-term consequences of a sedentary lifestyle. A sedentarylifestyle can lead to serious health risks such as obesity and diabetes. This gives exergames anopportunity to be implemented in the daily life of the affected. Exergames have evolved frombeing solely playable from their own console such as Wii or Xbox Kinect to only needing a webcamera, making it accessible and portable for office workers and others all around the globe. Theonly thing left is the actual exergames themselves. The goal of this thesis is to expand an existinglibrary of exergames with a unique boxing game. The research questions are as follows, 1: Howshould the game be designed to incite large body movements? 2: How will achieving higherscores impact the players' movement? Answering research question one will involve a lot of trialand error and creative thinking to come up with a solution that answers the question but alsofeels good to play. Research question two will require user data collected during the gameplay tobe analyzed to see relations between the total movement and the total score. Tracking elbows todetect whether a cube is hit as well as having cubes always spawn on opposite sides is anefficient way to incite large body movements as the player needs to rotate the entire upper bodyand reach further than tracking the wrists would have required. The analyzed user data showedthat there was a linear relation between achieving a higher score and the total movementexercised during the game. Gaps between the right-hand elbow and left-hand elbows’ totalmovement were also found.
