Pegasos: a framework for the creation of direct mobile coaching feedback systems

Feedback is essential for athletes in order to improve their sport performance. Feedback systems try to provide athletes and coaches not only with visualisations of acquired data, but moreover, with insights into—possibly—invisible aspects of their performance. With the widespread adoption of smartphones and the increase in their capabilities, their use as a device for applications of feedback systems is becoming increasingly popular. However, developing mobile feedback systems requires a high level of expertise from researchers and practitioners. The Direct Mobile Coaching model is a design-paradigm for mobile feedback systems. In order to reduce programming efforts, PEGASOS, a framework for creating feedback systems implementing the so-called Direct Mobile Coaching model, is introduced. The paper compares this framework with state-of-the-art research with regard to their ability of providing different variants feedback and offering multimodality to users.
