| description | Visual impairment affects individuals with complete or partial loss of vision. Visually impaired students in Colombian educational institutions face challenges when navigating indoors due to the lack of braille signage. This paper presents the development, implementation, and testing of an augmented reality (AR)-based mobile app that uses rMQR codes to play acoustic descriptions of locations. The application enhances the independence and mobility of visually impaired students in academic spaces. The process involved designing a navigation system, developing software using Unity and Vuforia, and evaluating the application's functionality, accuracy, stability, and performance. A group of thirty-six (36) students validated the software, and their feedback was gathered through a questionnaire using a 5-Likert scale. The results showed that the app had an accessible interface, provided useful information about spaces, and improved autonomy and safety. The app demonstrated fast and accurate code scanning, and its effectiveness in promoting independence, meeting expectations, and not interfering with mobility was validated. The findings emphasize the potential of AR-based applications in supporting visually impaired individuals and fostering social inclusion. |

La discapacidad visual afecta a personas con pérdida completa o parcial de la visión. Los estudiantes con discapacidad visual en instituciones educativas de Colombia enfrentan desafíos para navegar en interiores debido a la falta de señalización en braille. Este artículo presenta el desarrollo, implementación y prueba de una aplicación móvil basada en realidad aumentada (RA) que utiliza códigos rMQR para reproducir descripciones acústicas de ubicaciones. La aplicación mejora la independencia y movilidad de los estudiantes con discapacidad visual en espacios académicos. La metodología incluyó el diseño de un sistema de navegación, el desarrollo de software utilizando Unity y Vuforia, y la evaluación de la funcionalidad, precisión, estabilidad y rendimiento de la aplicación. Un grupo de treinta y seis (36) estudiantes validaron el software, y se recopilaron sus comentarios a través de un cuestionario utilizando una escala de Likert de 5 puntos. Los resultados mostraron que la aplicación tenía una interfaz accesible, proporcionaba información útil sobre los espacios, mejoraba la autonomía y la seguridad. La aplicación demostró un escaneo rápido y preciso de los códigos. Validamos la efectividad de la aplicación para promover la independencia, cumplir con las expectativas y no interferir con la movilidad. Los hallazgos resaltan el potencial de las aplicaciones basadas en realidad aumentada en el apoyo a personas con discapacidad visual y fomentar la inclusión social.
