Some people with intellectual disability also
present communication deficiencies. Augmentative and
Alternative Communication (AAC) is a strategy to deal with
such deficiencies. AAC exploits more than one communication
channel to send messages. In this paper we develop a
collaborative system that uses AAC in tablets to support the
dialog of these people. This research uses Design Science
Research, Participatory Design and the test case of Nielsen to
evaluate the solution. The results show that the system allows
to accomplish the communication and it can be used in
classrooms to improve the educative ways of people with
intellectual disability.
