Gaze-tracking-based interface for robotic chair guidance

This research focuses on finding solutions to enhance the quality of life for wheelchair users, specifically by applying a gaze-tracking-based interface for the guidance of a robotized wheelchair. For this purpose, the interface was applied in two different approaches for the wheelchair control system. The first one was an assisted control in which the user was continuously involved in controlling the movement of the wheelchair in the environment and the inclination of the different parts of the seat through the user’s gaze and eye blinks obtained with the interface. The second approach was to take the first steps to apply the device to an autonomous wheelchair control in which the wheelchair moves autonomously avoiding collisions towards the position defined by the user. To this end, the basis for obtaining the gaze position relative to the wheelchair and the object detection was developed in this project to be able to calculate in the future the optimal route to which the wheelchair should move. In addition, the integration of a robotic arm in the wheelchair to manipulate different objects was also considered, obtaining in this work the object of interest indicated by the user's gaze within the detected objects so that in the future the robotic arm could select and pick up the object the user wants to manipulate. In addition to the two approaches, an attempt was also made to estimate the user's gaze without the software interface. For this purpose, the gaze is obtained from pupil detection libraries, a calibration and a mathematical model that relates pupil positions to gaze. The results of the implementations have been analysed in this work, including some limitations encountered. Nevertheless, future improvements are proposed, with the aim of increasing the independence of wheelchair user

Diseño de una escape room basada en la gestión del ruido ambiental

La era digital trae consigo grandes cambios no solo en las necesidades, sino también en las inquietudes de las personas. Ante estos nuevos escenarios la Educación Técnica Superior se está adaptando, cambiando las metodologías didácticas y de aprendizaje, con el fin de satisfacer las necesidades de sus estudiantes. Hoy en día, uno de los métodos más recientes y recurrentes que se están introduciendo en la enseñanza como complemento a la enseñanza tradicional es el uso de la Escape Room, una técnica de gamificación que coloca al alumnado en el proceso activo del aprendizaje mediante elementos propios de los juegos. El objetivo de este trabajo es diseñar, implementar y evaluar una Escape Room virtual basada en los conocimientos que se imparten sobre Gestión del Ruido Ambiental en la asignatura de Gestión del Ruido Ambiental y de la Industria. La finalidad de esta herramienta es que los estudiantes puedan asentar dichos conocimientos mediante la realización de un caso práctico de forma lúdica, además de aumentar su compromiso y motivación en la asignatura.The digital age brings with it great changes not only in people's needs but also in their concerns. Faced with these new scenarios, Higher Technical Education is adapting and changing teaching and learning methodologies in order to meet the students’ needs. Nowadays, one of the more recent and reoccurring methods in teaching as a complement to traditional teaching is the use of Escape Rooms, a gamification technique that places the student in the active learning process through a series of games. The aim of this work is to design, implement and evaluate a virtual Escape Room in the Environmental and Industry Noise Management subject. The purpose of this tool is that the students, through the realization of a practical case, can consolidate the theoretical knowledge of Environmental Noise Management, as well as increase their commitment and motivation in the subjectDepartamento de Física AplicadaGrado en Ingeniería en Organización Industria
