The objective of this article is to demonstrate how the experience of engineering students engaging directly with users, in this case patients with Parkinson's disease, in brigades and on Saturdays in Motion allows them to understand the problem and convert it to software technical requirements, with a direct impact on their engineering learning process; which is not just about data and numbers, but with human beings and all the complexity that this entails. The criterion beyond the professional competence itself by direct experience and rotation of tasks in the brigades, evidence the technical requirements of usability and the persistence of data, which makes the difference between an appropriate application or a big failure.
