Abstract
La integración de tecnologías digitales en la vida cotidiana ha generado una brecha significativa para el segmento de la tercera edad. Los controles remotos modernos, caracterizados por una alta densidad de botones e interfaces complejas, imponen una carga cognitiva excesiva que limita la autonomía de los adultos mayores en actividades de ocio básicas. Esta memoria presenta el diseño, implementación y validación del Sistema de Asistencia IR Configurable (SAIC), una solución tecnológica híbrida que desacopla la complejidad de la configuración y variedad de operaciones de controles remotos de la simplicidad de las operaciones de uso diario. El sistema consta del dispositivo SAIC basado en el microcontrolador STM32L476RG, diseñado con una interfaz minimalista de botones grandes, y una aplicación móvil Android (“IR-Link Admin”) que permite a un administrador configurar de manera inalámbrica las funciones y macros del dispositivo vía Bluetooth. La implementación técnica destaca por el desarrollo de un firmware Bare-Metal eficiente, utilizando una arquitectura no bloqueante basada en interrupciones para la síntesis precisa de protocolos infrarrojos (NEC y RC5) y un protocolo de comunicación serie robusto (MTR-Link). Asimismo, se incorpora un sistema de persistencia de datos en memoria Flash. Los resultados de la verificación demuestran que el dispositivo SAIC garantiza un alcance superior a 5 metros y una autonomía estimada de 50 horas en uso continuo, validando su viabilidad como herramienta de asistencia tecnológica efectiva y replicable.
The integration of digital technologies into daily life has created a significant gap for the elderly population. Modern remote controls, characterized by high button density and complex interfaces, impose an excessive cognitive load that limits the autonomy of older adults in basic leisure activities. This thesis presents the design, implementation, and validation of the Configurable IR Assistance System (SAIC), a hybrid technological solution that decouples configuration complexity from operational simplicity. The system consists of a physical hardware device based on the STM32L476RG microcontroller, designed with a minimalist interface of large buttons, and an Android mobile application (“IR-Link Admin”) that allows an administrator to remotely configure device functions and macros via Bluetooth. The technical implementation features the development of efficient Bare-Metal firmware, utilizing a non-blocking interrupt-based architecture for the precise synthesis of infrared protocols (NEC and RC5) and a robust serial communication protocol (MTR-Link). Furthermore, a data persistence system is incorporated using EEPROM emulation in Flash memory. Verification results demonstrate that the device guarantees a range exceeding 5 meters and an estimated autonomy of 50 hours in continuous use, validating its viability as an effective and replicable assistive technology tool.
