    Desarrollo de una aplicación de realidad aumentada y visión artificial para el mantenimiento de ventiladores mecánicos
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Maestría en Electrónica y Automatización, 2022) Poveda Ocaña, Héctor Fabián; Galarza Zambrano, Eddie Egberto
    The present work shows the development of a maintenance system for the Savina 300 intensive care ventilator using augmented reality as a guide for the user. The identification algorithm has used a neural network trained with a 3D model of the respirator and the configuration of several relevant details for the training process. The objective execution platform is a mobile device with Android 11 operating system and motion sensors (gyroscope and accelerometer) that allows versatility, mobility and a low-cost implementation of the solution. The detection has been successful in execution times which allows an overlay of the 3D elements on top of the real fan. The proposed structure and work route offers robustness for the implementation of more maintenance tasks in the future. The validation has been carried out using the well-known SUS usability test in which the application reached a value of 82.5, which indicates that it is advisable to make improvements at the user interface and message display level in case of needing a better coefficient.
