Though the degree varies , deaf people in differentiates of the world are facing challenges to communicate wit h hearing people. The situation in Ethiopia is similar' except there has been no remedy tried to bridge the gap. As per the investigation of this research, deaf people face communication problems of various kinds in perusing their day to day activities with their herring acquaintances. It has been observed that the deaf people are denied so many advantages because of the communication gap they have with the hearing people. The problem was more serious in public service rues leek e hospitals , police stations , etc . In other countries, different options have been suggested and used to resolve communication gap between the deaf and herring people. Teaching sign language to herring people has been considered as one of those ways of bridging the communication gaps between the hearing and the deaf people. Beru'ing in mind that Ethiopian Sign Language (ESL) is used as an effective mode of communication for deaf people in Ethiopia, the main aim of this study was intended to bridge minimize the existing communication gap between deaf and herring people (taking health environment as a case) , by creating hypermedia software that can be used to teach ESL. The software is supposed to help health professionals to learn basic health related Ethiopian Sign Language, so that they can communicate to their deaf customers. In order to achieve the aim of the study, this reserpine first reviews the Various related literature. Then user research was done using questionnaire in order to have a good input to the design of appropriate tool. Based on the analysis of the user research, a prototype of the hypermedia tool was developed. The tool was designed using a UML based hypermedia designing methodology . The whole process of developing the tool , including the design, was based on the ISO-13407 standard for user centered design The prototype was developed based on continuous evaluation of the in tended users. More over final evaluation was done using a co-discovery method of usability testing and it has been observed that, the tool was developed to the appropriate skill and need of the intended users
