Item Plataforma de interacción virtual para la navegación de visitantes primarios en los predios de la UTA del Campus Huachi usando un avatar y algoritmos de machine learning(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Sistemas Computacionales e Informáticos, 2023-09) Palate Amaguaña, Alexis Israel; Nogales Portero, Rubén EduardoPeople who do not know a place of interest have problems on their first visit, causing them a bad experience. In this context, a person can look for alternatives to get to know these places virtually, before getting to know them physically. However, most of the options are not a reflection of reality. Basically limiting them to see the exteriors of a place. In this sense, a virtual interaction platform is proposed where the user can control an avatar with hand gestures, to get to know a place virtually before getting to know it physically. In this way you can improve your experience on the first visit to the places that are of interest to you. In this project, a 3D model of the Huachi campus of the Technical University of Ambato (UTA) is proposed. This platform works with two integrated systems, running on the same computer. The first system consists of a hand gesture recognition model. This system uses the Leap Motion Controller sensor to capture the gestures made by the user. These data are sent to the model. This is in charge of processing them using a KNN classifier, to predict a label that represents the gesture. Subsequently, the predicted label is sent through the TCP/IP communication protocol, with the local IP address of the computer where the platform is running. The second system receives the label and interprets it as an instruction that the avatar must comply with by performing an action within its virtual environment. The platform was tested by 15 people. A group of 5 people who do know the UTA, and another group of 10 people who do not know the UTA, giving priority to people who do not know the UTA. The model was tested by the researcher, performing 20 repetitions for each gesture. Finding that, with kn=5 and frames=400, an accuracy percentage of 100% is obtained in the Open Hand gesture, 85% in the Close Hand gesture, 65% in the Wave In gesture, 95% in the Wave Out gesture, and 10% on the Pinch gesture. These gestures are used for the interaction of the avatar with the virtual world. However, the action corresponding to the Pinch gesture is limited, due to its low percentage of accuracyItem Sistema de teleoperación con realidad virtual para la manipulación de un robot móvil(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Telecomunicaciones, 2023-08) Galarza Toapaxi, Bryan Raúl; Ayala Baño, Elizabeth PaulinaDuring the last years the industry has grown significantly to what is now known as Industry 4.0 and all this goes hand in hand with robot automation. Industries began to use mobile robots to optimize certain manufacturing tasks and have the best possible result, avoiding human errors, in addition to ensuring the possibility of carrying out different tasks in areas where people do not have access, since these are areas that are difficult to enter or that are harmful to people's health. The problem with this is the lack of knowledge about the operation and correct use of the robot. Due to these factors, this research project presents the development of a virtual reality teleoperation system, using the HTC Vive Pro 2 virtual reality glasses. This will allow the person to immerse themselves in a completely virtual environment to become familiar with the operation and control of a robot, adapting to their needs, in this case it is the Kuka Youbot which contains ROS as an operating system. The control system of the robot with virtual reality is developed using the Unity 3D graphics engine, allowing it to connect with the robot's ROS operating system and execute movement orders according to the needs of whoever is manipulating it. Also, the control of the robot is carried out through simulation in Gazebo, facilitating the understanding of its operation and preventing possible damage to the real robot. This research work is linked to the research project "Use of deep learning techniques for optimization of autonomous trajectories of mobile robots within an industrial process" and benefits all students who are interested in expanding their knowledge in the world of robotics.Item Sistema electrónico de ayuda pedagógica para niños con necesidades educativas especiales utilizando realidad aumentada.(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Telecomunicaciones, 2023-03) Chisaguano Jácome, Sara Raquel; Manzano Villafuerte, Víctor SantiagoChildren with special educational needs not associated with disability are children who have difficulty accessing common learning according to their age, accordingly, the curriculum was adapted to the level of competence that develops, including specific resources to improve their teaching-learning process, for this reason, the electronic pedagogical aid system for children with special educational needs using augmented reality, in order to improve the learning of children, interacting with new technologies while assimilating information in a visual and auditory way. The system was developed using the recommendations of the teachers and the psychopedagogues of the educational institution, based on the psychopedagogical report submitted by the District Unit of Support for Inclusion, in which the degree of curricular adaptation is specified, the level of competence according to each academic area, the student's learning style and the strategies to be followed by teachers, parents and psycho-pedagogues. The system is based on the interaction of the child with an augmented reality application performed on an Android device, which shows 3D models and interactive videos related to the subjects of Natural Sciences, this is stimulated when the application recognizes a marker and performs a process of detection and tracing of images, which was developed by the graphical engine of Unity 3D together with the SDK ARCore, in turn, are reproduced descriptive audios and environmental sounds. After, the child interacts with the system hardware by observing pictograms and answering questions that the device generates about what is learned, this by communicating between the Arduino Mega development board and the prototype pencil that simulates the crushing of a button. This system allows the student with special educational needs, to strengthen their knowledge, associating sounds and images, which has an impact on the development of their cognitive abilities, such as attention and concentration, influencing the improvement of their academic levelItem Sistema de realidad aumentada para el entrenamiento de estudiantes en el manejo de instrumentación Hart de la Facultad de Tecnologías de la Información, Telecomunicaciones e Industrial de la Universidad Técnica de Ambato(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial en Procesos de Automatización, 2020-01) Bologna Coronel, Jenniffer Kimberley; García Sánchez, Marcelo VladimirLos equipos programadores de dispositivos industriales permiten realizar un diagnóstico preciso del funcionamiento de los equipos de campo y de los segmentos de comunicación, sin embargo es fundamental crear nuevas estrategias de aprendizaje para el correcto uso de estos dispositivos. Así pues se considera a la RV (Realidad Virtual) como una herramienta de entrenamiento en el campo industrial, porque brinda experiencias virtuales que son imposibles en un entorno real, en términos de seguridad y costo. Por estas razones, la investigación realizada presenta un sistema de realidad aumentada que brinda a los usuarios una experiencia más real con complementos virtuales, para el entrenamiento en el manejo de instrumentación HART, utilizando la plataforma de desarrollo de entornos virtuales Unity 3D, que ofrece un enfoque en el que las demandas modernas de capacitación y los requisitos necesarios que debe cumplir para la utilización de dispositivos de campo, se pueden integrar en una sola aplicación, ofreciendo una tremenda ventaja para los usuarios, ya que pueden operar equipos costosos en su propia computadora en un entorno que perdona los errores. La validación del sistema se realiza mediante un módulo de evaluación, que le permite al usuario determinar el nivel de entrenamiento y construir de manera autónoma su propio aprendizaje, obteniendo respuestas positivas que evidencian que alrededor del 82% de los individuos evaluados tanto profesionales como estudiantes percibe un aprendizaje satisfactorio luego del entrenamiento, y una mejora del tiempo empleado en capacitación de un 55%. Por lo tanto el sistema propuesto es capaz de optimizar el proceso de entrenamiento y capacitación del usuario, en tiempo real, de manera eficiente, y con alto nivel de inmersión y comprensión del contenido. ABSTRACT The use of problem-detecting devices in the industry is increasingly necessary to provide intrinsically safe environments within processes. Industrial device programmers allow technicians to solve problems while they continue working, making an accurate diagnosis of the operation of equipment and communication segments, however, it’s essential to create new learning strategies for the correct use of these devices. So VR (Virtual Reality) is considered as a training tool in the industrial area, because it provides virtual experiences that are impossible in a real environment, in terms of safety and cost. For these reasons, the research carried out presents an augmented reality system that provides users a more real experience with virtual add-ons, for training in the HART instrumentation handling, using the Unity 3D virtual environment development platform, which offers an approach where modern training demands and the necessary requirements that must be done to the use of field devices can be integrated into a single application, offering a tremendous advantage for new engineers because they can operate expensive equipment on their own computer in an environment that forgives mistakes. System validation is done through an evaluation module, which allows the user to determine the level of training and autonomously build their own learning, obtaining positive responses that show that about 82% of the people evaluated, both professionals and students perceive satisfactory learning after training, and an improvement of the time spent in training of 55%. So that, the proposed system is capable of improving the process of user training, in real time, efficiently, and with a high level of immersion and content understanding.
