Problem The hearing impaired have a difficult time communicating with individuals that do not know sign language. These difficulties can cause a hearing impaired individual to limit their activities in order to avoid frustrations and embarrassment. Ten million Americans are hard of hearing and one million are functionally deaf. (Mitchell 2005)

Existing Solutions Issues Human Interpreter Written Communication Verbal and Signed Communication Dependency Cost Time Consuming Awkward Frustrating Awkward
