Abstract
Esta memoria de título presenta un análisis de la experiencia de usuario de DialogApp, una aplicación móvil diseñada para mediar la comunicación entre pacientes Sordos y profesionales de la salud en Chile. A través de una metodología de Diseño Centrado en la Persona, que incluye la creación de dos perfiles de usuario comparables, pruebas de usabilidad moderadas y el análisis de métricas cuantitativas y cualitativas, se identifican problemas críticos de interacción y se propone un rediseño de interfaz fundamentado en la evidencia. El estudio concluye que la viabilidad de las tecnologías de asistencia como DialogApp no reside únicamente en su precisión algorítmica, sino, de manera fundamental, en una experiencia de usuario que sea confiable y adaptada a las necesidades de la población Sorda. Asimismo, se determina que elementos como la expresividad no manual del avatar y la retroalimentación visual constituyen componentes funcionales esenciales para la usabilidad y la aceptación por parte de la comunidad Sorda, sentando las bases para una herramienta con el potencial de mejorar significativamente la autonomía y la calidad de la atención sanitaria.
This thesis presents a comprehensive analysis of the user experience of DialogApp, a mobile application designed to mediate communication between Deaf patients and healthcare professionals in Chile. Through a Person-Centered Design methodology, which includes the creation of user personas, moderated usability testing, and the analysis of quantitative and qualitative metrics, critical interaction issues are identified, and an evidence-based interface redesign is proposed. The study concludes that the viability of assistive technologies like DialogApp does not rely solely on algorithmic accuracy, but fundamentally on a user experience that is intuitive, reliable, and culturally resonant. It is demonstrated that elements such as the avatar's non-manual expressiveness and visual feedback are essential functional components for the usability of DialogApp by the Deaf community, laying the groundwork for a tool with the potential to significantly improve autonomy and the quality of healthcare.
