DESCRIPTION
Although recording classroom presentations and tutorials for ordinary learners is not a new idea, little effort has been applied to provide simple solutions to prepare complementary video materials to deaf/hearing impaired students or those with learning or auditory perceptual disability who tend to be visual learners and have difficulty in watching a teacher and take notes from a screen or blackboard simultaneously. RealShow automates the process of producing effective video materials for those learners and provides functions that combine popular PowerPoint slides, freehand drawings and illustrations, screen typing, and teacher’s video sign language translation in one single window.

Background: Video
In conclusion There is increasing
interest in providing students with recorded class materials and multimedia content.
