Evaluación de la accesibilidad en sistemas de teleconferencia para usuarios con baja visión durante la covid-19

The World Health Organization indicates that more than 1 billion people worldwide live with some form of disability; about 200 million people experience significant difficulties in their physical functioning. In the future, disability will be a considerable concern, as it tends to increase as the population ages and the risk of disability is higher in older adults because their vision decreases with age. On the other hand, the COVID-19 has accelerated technology by encouraging teleworking in the areas of education, health, and business. However, not all applications comply with accessibility standards. In this study, the ten most used applications in teleconferencing are taken to evaluate compliance with accessibility guidelines, related to the principles: perceptible, operable, understandable, and robust, proposed in WCAG 2.1 and WCAG 2.2.
