The computer programmed multi-image lecture.

Abstract

Computer programmed multi-image presentations enhance considerably the visual content of an audiovisual presentation. A multi-image production provides ample opportunity to present the pre- and post-operative images simultaneously, enabling the audience to compare and comprehend the results with ease. With more than one image the natural sequence of dissection details can be shown, resulting in continuity of thought. The dissolve mechanism offsets any visual fatigue of the audience. The films contribute animation sequences which cannot be demonstrated well on slides. A presentation of all material provides the lecturer with maximum control with the minimum of effort, utilising one button. A computer programmed multi-image production is a complex medium of audiovisual presentation and needs a great deal of time and experience and is not to be lightly undertaken. With the increased number of slides, images and projectors the margin for error is small. Careful slide assembly and repeated rehearsals are the keys to success. At the moment, its use is recommended for special lectures only with adequate consideration being given for the increased expense of production.
