This paper presents a magnetic matching-aided indoor localization system based on a waist-mounted self-contained sensor array. Our purpose is to localize and track the elderly in nursing homes through the proposed wearable device to ensure their safety. The device consists of a low-cost 9-axis self-contained sensor array, a microcontroller, and a WiFi transmission module. This system uses the step length and heading-based pedestrian dead reckoning (PDR) framework as the backbone to estimate the user’s position using the averaged inertial data from the sensor array. A magnetic fingerprint matching (MFM) algorithm is introduced to constrain the drift of the PDR system. Meanwhile, we construct a single-step-based hybrid magnetic fingerprint model to improve the low discernibility of the magnetic field. Finally, we propose an augmented particle filter to fuse the PDR and the MFM algorithms to enhance the system performance further. Experimental results show that 95% of the positioning error after fusion is about 1.47 m, which is 99.3% higher than that of PDR, and the average positioning error after fusion is 0.55 m, which is 61.3% higher than that of PDR. Experimental results have successfully validated the effectiveness and high performance of the proposed magnetic matching-aided wearable indoor localization system.

“…En el segundo sistema, se han diseñado módulos transceptores que se comunican con etiquetas RFID (identificadores por radio frecuencia), las cuales también son instaladas en puntos estratégicos y equidistantes, señalizando la zona o punto específico de su localización [22]. El módulo transceptor también envía comandos de voz a la persona que lo porta proporcionando información precisa para que realice su desplazamiento desde un punto inicial a otro punto final del interior del edificio.…”

La pandemia por la COVID-19 ha evidenciado la necesidad de un desarrollo sostenible de nuestro país e incrementado las desigualdades sociales, implicando que los gobiernos tengan un reto mayor por reducirla. Sin embargo, no solo hay que esperar que el gobierno de turno lo enfrente, sino que todos debemos colaborar en la solución de este problema. De esta manera, las universidades, mediante actividades de investigación y desarrollo también pueden aportar. Este trabajo presenta, de manera resumida, las acciones que ha estado realizando la Universidad Tecnológica de Panamá (U.T.P.) con miras a crear comunidades innovadoras mediante proyectos sostenibles en el tiempo, para el beneficio de sus ciudadanos. Aquí se comparten las características principales de propuestas, proyectos y los diferentes programas de desarrollo comunitario, con el fin de promocionar, divulgar y replicar las buenas prácticas con la premisa de la interacción del conocimiento de los estudiantes en la búsqueda de soluciones a los problemas de las comunidades

“…These devices often rely on ultrasonic sensors or infrared sensors to quickly determine the user's spatial relationship with objects in the surroundings. When it comes to environmental designs for the visually impaired, apart from urban planning initiatives, there are also efforts focused on community redesign and the deployment of radio-frequency identification (RFID) technology [4] to achieve barrier-free mobility. While methods like this have the potential to address the problem fundamentally, they require significant resources and may have slow results, serving as a long-term vision for future smart living.…”

Outdoor navigation has long been a wicked problem for the visually impaired. With the development of technologies, new designs with them are temping to deal with existing obstacles both from within and outside, but still leaving pain points to be solved. Driven by social considerations and user-centred perspectives, we propose an innovative and sustainable design framework for assistive devices catering to the visually impaired in this project. The core implementation layer utilizes Arduino, while the decision-making layer employs the YOLOv5 algorithm for object detection tasks, enabling hardware interaction in response to the detection results. The device successfully provides features such as environmental information feedback, tactile paving search and privacy intrusion warning, transforming necessary visual information into auditory and tactile feedback. By controlling it at a lower cost and simplifying interaction methods, our device offers essential mobility assistance to a broader range of visually impaired users.
