This application is the result of the project developed by Guilherme Lima and Jackeline Soares, Internet Systems Technology students at IFRN. The team was guided by Prof. Dr. Bruno Emerson Gurgel Gomes. The aim of the work was to develop an application for mobile devices based on the Picture Exchange Communication System (PECS), known in Portuguese as picture exchange communication system. The application will allow children, with monitoring and teaching dynamics, to choose figures that represent the action they want to express or, upon reaching certain learning levels, to choose images with subtitles that will be sounded by the mobile device.
