- Abstract
This article describes an empirical research on the impact of a computer system called TEVI (Virtual Keyboard) designed to facilitate communication for children with language problems caused by a physical disability. The methodology used in the research was based on four phases: in the first phase, an exploratory research was conducted through surveys and unstructured interviews to authorities and ten teachers from two special education schools in two provinces of Ecuador. In the second phase, the computer system was developed. The system is divided into three modules: input (User interface), data processing (database manager) and output (Natural Language Processing algorithms). In the third phase, a preliminary evaluation of the prototype is made with specialists and a person with motor disabilities. Finally, in the fourth phase was carried out an experimental evaluation in which 75 children of school age, including the 80 % with language problems because of their physical disabilities. The instrument for evaluation has a panel of pictograms and a virtual keyboard with predictive text. The time registered in the activities with teachers was processed with a general linear univariate statistical analysis. The results showed a decrease of 57.3 % of the time in the input of information using the panel of pictograms compared to the virtual keyboard. In addition, a qualitative analysis allowed collecting events and comments from teachers who said that TEVI is a potential tool to develop learning strategies.
