Abstract— Dissemination of handheld systems, binary technologies and branch of communication suppliers and organization structure greatly assists on modes of medium and activities among members everywhere the globe. This Revolution in modes of medium could provide a good chance for those that use supportive systems because of some sorts of incapacity, but it had become a binary severe barrier at an equivalent space-time. Supportive systems provides individuals with dysfunctions is a action gadget to boost their involvement, incorporation, and self-rule, in particular for individuals with dysfunctions that involve additional senses, such as deaf-dumb, that is that the combination of dumb and deaf. Sign Language has become a medium of communication with dumb persons. Gesture dialect are employed by dysfunctions individuals to speak among them however those Gesture dialect vary from country to country as yank signing, Britain signing, Chinese signing etc. The proposed system has supported Indian gesture languages. The challenge here involves many cases: (i) initial case could be a handicapped person sometimes doesn’t speak so as a deaf man to listen to him/her; (ii) second case is once a deaf man speaks another deaf person cannot hear; (iii)third case is once a dumb person makes signing a deaf man cannot understand them. Thus, this paper presents a study on multi-modal interfaces, problems and issues for establishing communication and interaction between dumb and deaf persons through sign languages and hand gestures using IOT.
