The focus of this thesis is the development of an exergame prototype designed for the rehabilitation and telerehabilitation of the upper limbs. Development focused on creating a game set in a gym environment, using Google's Mediapipe library to detect the user's movements and spatial positioning. The exergame was built using the Unity game engine, based on an existing open source solution that integrates Mediapipe's pose detection via a Python script with a Unity sample scene. From this, the solution was further developed by incorporating a server-side component, consisting of a NodeJS server and a MongoDB database, to store all data collected during the exercises.
