Cortez Vallejo created two computer programs so persons with visual disabilities could learn to write well and interact on Twitter. During an interview with the News Agency of Mexico’s National Council of Science and Technology (CONACYT), he described the Natural Intellectual Assisted Typing (DANI) program, a platform that helps users through a screen with a voice system.
The software developer added that his program is designed to help the blind learn to type on a keyboard because it contains timed tests for dictations, and alerts the user of any errors.
Manuel Eduardo said the reason they decided to create DANI was because people with visual disabilities often need to count the letters, which makes the process of learning to write on a computer slower.
Another program design is the TWBlue, which lets the user connect to Twitter, providing a quick and convenient option for users. Aside from facilitating access to the social network, it helps to speed up reading tweets, write more words in a message, and is more comfortable because it streamlines the page and can send messages of up to 10,000 characters with spell-check.
The program comes in 16 languages, thanks to contributions from other users, and has a system that reads the messages. TWBlue uses free software and sustains itself with donations. So far it has 10,000 users.
Cortez Vallejo added that currently he is working on a software upgrade that may be used by people with hearing and mobility disabilities.
