Evaluating Signage Accessibility for Individuals with Visual Impairments: A Case Study in Ecuador

2024 , Arias Flores, Hugo Patricio , Valencia-Aragón, Kevin , Sandra Sanchez-Gordon , Tania Calle-Jimenez

A signage system is a visual design consisting of identification, guidance, explanation, warning, and other functions through a combination of text, graphics, and color that facilitates the orientation and movement of occupants in buildings by representing explicit information about the configuration and overall structure of the building. In this sense, well-placed signage provides information and significantly influences the search for paths in public spaces, but not all of these spaces meet the conditions of accessibility and inclusion. From this perspective, the general objective of this research is to identify, analyze, and evaluate the shortcomings of signage for individuals with visual impairments based on the requirements and legal regulations in Ecuador. The methodology was based on collecting photographs of signage located in a higher education institution. These photographs were selected in a way that they encompass the most important characteristics of informative signage. The results show that 44.44% comply with the current regulations in Ecuador, and 66.66% comply with the regulations for the inclusion of individuals with low vision. In the future, it is considered to propose a signage system that incorporates technology.

Learning Through Play: Implementing an Educational Escape Room for Teaching Traditions and Culture

2025 , Valencia-Aragón, Kevin , Arias Flores, Hugo Patricio , Zapata, Mireya , Luis Aguirre-Morales , Sandra Sanchez-Gordon

This study explores the implementation of an educational Escape Room as a pedagogical strategy to teach tangible cultural heritage to students in Ecuador. This Escape Room was designed using the ADDIE model (Analysis, Design, Development, Implementation and Evaluation) and integrated into the basic education curriculum for Ecuadorian schools. The primary objective was to enhance students’ engagement and understanding of Ecuador’s cultural heritage through an interactive and gamified learning experience. The Escape Room was structured around five missions, each focusing on different aspects of the cultural heritage of five parishes in Ecuador. Students were required to solve puzzles, answer questions, and complete challenges to progress through the game. The results of the implementation, evaluated through observation and student feedback, indicated a high level of student engagement, improved problem-solving skills, and a deeper appreciation for Ecuador’s cultural heritage. The study concludes that Escape Rooms can be an effective tool for teaching cultural heritage, fostering teamwork, creativity, and critical thinking among students. This innovative approach not only makes learning more dynamic and enjoyable but also aligns with modern educational trends that emphasize active and experiential learning.

Artificial Intelligence and Assistive Technologies: A Systematic Review of Educational Applications for Disabilities

2025 , Arias Flores, Hugo Patricio , Valencia-Aragón, Kevin , Tania Calle-Jimenez , Sandra Sanchez-Gordon

The global population of individuals with disabilities, representing 15% of the world’s people, faces significant challenges in accessing higher education due to insufficient accessibility and persistent discrimination. This paper aims to evaluate the integration of artificial intelligence (AI) and assistive technologies in higher education to improve learning experiences for students with disabilities. Despite advancements in AI, only a small proportion of students with disabilities report satisfaction with existing inclusion efforts. Through a systematic review of the scientific literature from 2019 to 2023, this study examines the current use of AI in higher education, focusing on its application to enhance accessibility, personalized learning, and support for students with disabilities. The research highlights key areas such as intelligent tutoring systems, adaptive learning, and the role of educational technologies in fostering inclusion. While AI and assistive technologies hold great potential, challenges including ethical concerns, biases, and the low adoption rate of assistive technologies remain. The findings emphasize the need for further research to ensure that AI fosters genuine inclusion rather than exacerbating exclusion, urging continued efforts in developing more accessible educational environments for all students.

Eye-Tracking and Pictograms: Improving Communication and Accessibility for Senior Adults

2024 , Arias Flores, Hugo Patricio , Valencia-Aragón, Kevin , Sandra Sanchez-Gordon

An important factor in exploring the world around us and understanding the cognitive process of individuals is analyzing the characteristics and behavior of the eyes, as they provide reliable information. Improving communication processes with users through visual communication environments can create an accessible environment for virtual interaction. In this context, the global population is aging at a faster rate, leading to social transformation. This population segment may face challenges with language skills, health issues, psychological disorders, and traumas that can limit their ability to speak or move. The purpose of this study is to investigate whether eye-tracking, using the eye-tracking device, will enable senior adults to interact with their caregivers through a pictogram-based interface, allowing them to generate messages and communicate their needs. The research method involves the conceptual development of an experiment designed for senior adults, including the use of an eye-tracking device, calibration tests, and interface responses. This research aims to better understand and promote the importance of meeting the needs and expectations of the elderly segment.
