GURU: a multimedia distance-learning framework for users with disabilities

GURU is a distance-learning environment that renders multimedia information to users with disabilities in an accessible manner. It is an implementation framework developed as part of an effort to provide accessible multimedia information to end users with perceptual (visual and auditory), cognitive or motor impairments. GURU is based on the MPEG-4 standard, and it modifies MP4 content and the presentation of the different objects in the scene dynamically based on users' visual, auditory and motor abilities. This paper briefly describes the implementation of the prototype framework and illustrates sample adaptations as implemented in this framework.
