Designing and evaluating a free weight training application

Abstract: Physical activity plays a significant role in people's health, and the market for fitness apps is today a large growing market. This thesis work was conducted in conjunction with Advagym, Sony's connected gym solution that tracks activity using IoT sensors mounted on fitness machines to log detected exercises in a smartphone app. This work examines how to extend Advagym to include free weight training using multi-camera positioning. A human-centred design process has been applied to study use situations and create prototypes through several iterations, finally resulting in three smartphone apps. The apps are structured in three different ways regarding the amount of interaction, control and accuracy they provide when tracking and logging training with free weights. Lastly, comparative usability testing was performed with 18 participants to examine how fitness data is valuable to users and what level of interaction provides the best user experience.
