Durante los años 1999 a 2001 se ha desarrollado una investigación financiada por la O.N.C.E., con el objetivo de aprovechar los recursos que ofrecen las nuevas tecnologías en el ámbito de la estimulación visual. Como resultado se diseñó el programa EVO, mediante el cual la persona que lo maneja puede gestionar los ejercicios del entrenamiento visual, controlar los ajustes realizados sobre el material de trabajo, seguir los avances conseguidos con la intervención del programa. La estructura, dirigida a niños con patologías visuales de 4 a 13 años, es la siguiente: estimulación visual básica, estrategias de exploración y búsqueda, reconocimiento de objetos, manipulaciones espaciales, juegos de repaso
Se analiza el desarrollo y evaluación del sistema informático EVO que, en el ámbito de la estimulación visual, permite la evaluación de capacidades visuales y facilita la aplicación de programas de entrenamiento visual, basados en juegos de ordenador adaptados a las características visuales del usuario. Se refieren los antecedentes de la investigación, se indican las adaptaciones ergonómicas incorporadas al programa, y se describe su estructura funcional. Se presenta la evaluación realizada con 14 niños atendidos en el Centro de Recursos Educativos de la ONCE en Madrid. Los resultados muestran mejoras significativas, que sugieren la conveniencia de utilizar EVO complementariamente con los medios de estimulación tradicionales.

To an extent, vision is a function that can be learned. Broadly speaking, this learning -named visual perceptive development, takes place spontaneously. Nevertheless, it is not the case of a significant number of children who, due to their visual or perceptual impairment, have difficulties either receiving or processing visual stimuli from their environment. In this case, Visual Stimulation programs should be applied to these people so that their visual functions can be developed. The advances developed in last two decades on information and communication technologies, ICT, are not reflected in the existing software tools for the field. As a contribution to solve this problem, we have designed and developed an Interactive Educational System supported on a web platform with the main aim to provide professionals the required mechanisms to perform the basic Visual Stimulation tasks. At the same time, it takes advantage of the several opportunities offered by the Internet. In this paper, we analyze the limitations of previous existing tools and present EVIN (Visual Stimulation on the Internet). The main objective of the EVIN project is the development of a web platform which exploits the potential of ICT along with the experience gained by low vision professionals.
A significant number of children have difficulties either receiving or processing visual stimuli from their environment. To an extent, visual perceptive development can be improved by visual stimulation programs. These programs are usually guided by specialists in low vision that make use of different tools to help stimulation of the child. In addition, to make visual training more successful, the specialist in low vision needs to collaborate closely with parents and teachers taking into account the preferences and characteristics of each child. Traditional materials used in visual training are physical worksheets with special exercises and different colors and forms. Although these traditional worksheets have been recreated in computer programs, they currently have some limitations: (1) require that the specialist works with the child at the same place; (2) have a lack of assessment, monitoring and feedback mechanisms. To overcome these limitations, we have implemented EVIN, a web-based platform that provides games for visual training (among other things). In addition to the specialist, EVIN may and must be used by teachers at school and by parents at home. EVIN has monitoring capabilities and provides reports about children’s performance. In fact, reports of EVIN are to be assessed by the specialist in low vision. EVIN promotes a better integration of visually impaired children in schools and improves the children’s interaction with visual stimulation programs. In this paper, we present the main characteristics of EVIN and we focus on the Explorations game, the most popular game in EVIN.
