1 Introducción El uso de videojuegos para propósitos de aprendizaje ha sido uno de los temas de interés que ha surgido entre in-vestigadores y desarrolladores. Las investigaciones se han focalizado en su utilización principalmente en el aula (Fernández-Vara & Tan, 2008). Incluso algunos estudios han determinado que los videojuegos en computador (co...

There is a real need to have systems for people with visual disabilities to be able to improve their orientation and mobility skills, and especially for children to be able to improve their autonomy into the future. However, these systems must be designed according to available objectives, methodologies and resources, as well as by taking the inter...

Concept mapping is a technique that allows for the strengthening of the learning process, based on graphic representations of the learner's mental schemes. However, due to its graphic nature, it cannot be utilized by learners with visual disabilities. In response to this limitation we implemented a study that involves the design of AudiodMC, an aud...

Existe una necesidad real de contar con sistemas para que personas con discapacidad visual mejoren las habilidades de movilidad y orientación, es especial para que los niños puedan mejorar su autonomía en el futuro. Sin embargo, estos sistemas deben ser diseñados acorde a los objetivos, metodologías y recursos disponibles, así como también consider...

We present AudiodMC, an audio-based concept map design program for blind users aimed at virtual training and rehabilitation. We analyze the stages involved in the design of AudiodMC from a user-centered design perspective, considering user involvement and usability testing. The results show a high level of user acceptance, identifying key sound cha...

This study presents the design, implementation, and usability evaluation of AudioNature, an audio-based interface implemented for pocketPC devices to assist science learning in users with visual impairments. The usability evaluation sessions helped to redesign the interface and adjust it to the user's mental model while operating a pocketPC mobile...

Science learning for blind people is limited. For a variety of reasons there is a very low emphasis on science learning for such users, especially those from deprived communities. We have designed, implemented and evaluated the usability of AudioNature, an audio-based interface implemented for pocketPC devices to assist with science learning in use...

Los mapas conceptuales han sido utilizados en las últimas décadas como una técnica efectiva para la construcción de significado. En la educación, por ejemplo, los mapas han sido clave para apoyar el aprendizaje significativo en el aula. Sin embargo, su naturaleza gráfica restringe la utilización por parte de aprendices con discapacidad visual. Por...

A number of studies have proposed interactive applications for blind people. One line of research is the use of interactive interfaces based on sound to enhance cognition in blind children. Even though these studies have emphasized learning and cognition, there is still a shortage of applications to assist the development and use of memory in these...

Diverse studies using computer applications have been implemented to improve the learning of children with visual disabilities. A growing line of research uses audio-based interactive interfaces to enhance learning and cognition in these children. The development of short-term memory and mathematics learning through virtual environments has not bee...

Science learning in blind children is limited. Diverse reasons trigger a very low emphasis on science learning in these users, especially those from deprived communities. We have designed, implemented and evaluated the usability of AudioNature, audio-based interface implemented for pocketPC devices to assist science learning in users with visual im...
