Offering better opportunity for Deaf and Hard of Hearing students in learning Science, Technology, Engineering and Mathematics (STEM) has always been a top priority in the world in particular United States. As a consequence, American Sign Language (ASL) has improved drastically in recent years. For instance, the ‘Shodor Education Foundation’ has developed some technical sign language materials for the study of computational science. However it still lacks most of the signs related to the Computer Science. In addition, the need of an interpreter in ASL creates another challenge for Deaf and Hard of Hearing students in learning. There are software tools developed based on the Signing Avatar as interpreter that help for greater understanding of the concept with significant access to the curriculum. However, most of these tools perform just a direct translation from English Language which makes it difficult for Deaf and Hard of Hearing students to understand since their primary language is ASL. The main objective of this project is to design and implement a system that involves American Sign Language Dictionary (ASLD) consisting of all the necessary Computer Science terminologies in ASL for course work, a Parser that translates the English Language to ASL Text and a Signing Animation System to perform sign language gestures. Furthermore a Java based tool with Graphical User Interface (GUI) was developed. It embeds the teaching course materials such as Microsoft© Power Point slides in English and videos of avatar showing corresponding gestures of the course in ASL. An immediate benefit of this project is that, our tool will assist the teaching of Computer Science oriented courses for Deaf and Hard of Hearing Students in an effective manner.
