The product designer plays a crucial role in creating products that captivate and fulfill users’ needs in an exceptional way. Based on this, this work aimed to demonstrate how a user-centered product designer can play a crucial role in solving the pains of the target audience. With this in mind, this paper proposes the design of a dashboard for a clinical team to visualize a rehabilitation session, focusing the product on the user experience. Several Deep Learning (DL) algorithms are expected to be used to extract biometric data from the patients, in order to feed a Dynamic Difficulty Adjustment (DDA) module, based on Reinforcement Learning (RL). The method proposed in this study is based on the study of the customer experience. To this end, a roadmap was drawn up with the stages of developing a data visualization platform. Afterward, user satisfaction was assessed using the System Usability Scale (SUS), resulting in a usability score of 81.6 points. It can be concluded that analyzing the data from this study reinforces the ongoing importance of User-Centred Product Design in creating effective and successful digital products.
