Supporting Deaf Adult Learners Training in Computer Literacy Classes.

While Deaf learners are fluent in a signed language they need to know a written language when acquiring computer literacy skills. We aim to allow Deaf people learn at their own pace and in turn reduce the need to interpret written text. Classroom dynamics and teaching method were studied to extract how lessons were conducted. We then implemented our solution: an authoring tool to structure lesson content and a mobile prototype. The prototype uses South African Sign Language videos arranged according to pre-existing lessons exported by the authoring tool. Results from the user testing showed a reduction in number of representational states which instructions appear in as well as allowing Deaf learners to learn at their own pace.
