Adaptation of existing technologies and design of new digital document technologies should be undertaken with an understanding of the role these technologies can play in the affective, cognitive, and social processes of learning, and with sensitivity to the subculture of the communities expected to adopt them. Relevant work is being undertaken in many diverse communities of researchers and practitioners. Video Use in the Office and Education Video use in the office and classroom is increasing.
