I. Introduction and Problem Statement
The need and the benefits of learning a sign language are growing in popularity. People not only learn sign language as a response to their hearing impairment, or to communicate with their deaf family member/s, a growing proportion of hearing people want to be able to communicate with those of the deaf community [1]. The American Sign Language (ASL) is among the five most-used languages in the United States behind Spanish, Italian, German, and French, and has become one of the most popular language classes in colleges and universities. Many schools in the UK teach at least the British Sign Language (BSL) alphabet and there is an ongoing debate in the parliament for BSL to be a part of the national curriculum. Learning a sign language is as hard as learning any other foreign language, especially past the age of optimal language learning (around the onset of puberty) [2].
