Fitness tracker are very popular these days. They are used as an app on the mobile phone, on the Smartwatch or integrated into a fitness bracelet. With the help of such apps, you can record your own fitness activity and, depending on the device, also measure the number of steps, heart rate, distance traveled and speed. But how do these fitness apps work? And what does that have to do with math?

The mathematical steps that lie behind the fitness apps will be experienced at first hand and interactively in the fitness tracker CAMMP day. Using simple MATLAB codes, students will discover the mathematical basics of activities (walking, running, sprinting) and the mathematical tools for the evaluation of such activities - Fourier analysis. In this action-oriented module, students will collect their own activity data and use mathematical modelling to develop a model for measuring the completed steps. This only requires prior knowledge of functions.
