Análisis, diseño y desarrollo de un ambiente virtual de aprendizaje accesible para estudiates con discapacidad visual para la Universidad Politécnica Salesiana, Sede Quito.

Abstract

The prototype of AVIDA virtual environment was developed for collaboration with students with visual impairment in their learning process. Prototype was built using Java, MySQL, Apache and Netbeans because it is not proprietary software and therefore there will be no problems with future licensing. First usability that was delivered in the prototype is the use of the fingerprint as an alternative method for entering the application U.are.u 4500 sensor was used due to its ease of installation, being a plug&play USB device that is compatible with the Windows operating system since the 2003 version. Second usability of the application has is voice recognition through API Speech Recognition that transforms the voice captured by the computer microphone into text, which can be sent as a message in the chat that the application has. Use of this API resulted in the tool being dependent on an internet connection for its operation, using the mouse as a trigger for this usability. Third usability that was given is the possibility that the application in the form of audio indicates the menu options available to the user, usability is also used in the repository that reads the contents of the local and remote folder. This one is also used in it sent tasks when reading the screen indicating us that it is pending, using the keyboard as trigger for this usability.
