Hearing impairment may constitute a barrier for accessing to information and communication in public places. Since the oral communication forms the basis of the learning process, this problem becomes of particular relevance at schools and universities. To cope with this situation is not enough to provide a textual translation for people with hearing disabilities, society via educational authorities must facilitate alternatives that improve access to information and education to this collective. According to this reality, the possibility of having an alternative tool of communication based in the Spanish Sign Language (SSL) emerges as a contribution to help overcoming the communication obstacles that the students with this difficulty usually find. The Spanish law 27/2007 recognizes and regulates that the sign language has to be used as the means of support for oral communication for deaf, hearing disability and deaf-blind people. It also determines the rights of the people to decide loosely how to communicate, to not to be discriminated because of it and lays different application areas. According to this law, the design of a communication system based on SSL is proposed, with the aim of contributing to the Universal Accessibility as indicated by the International Convention on the Rights of the Persons with Disability.
