摘要

The Portable Presentation Package is a prototype of a self-contained package of audio and visual equipment designed to facilitate technical training particularly in (a) remote areas, (b) situations in which written communications are difficult, and (c) situations requiring rapid on-the-spot preparation of instructional material. The package contains the essential components required in preparing and giving visual and audio-visual presentations to small groups. The major criteria employed in developing the package were that (a) the equipment be easily portable by one man, (b) it utilize off-the-shelf items presently available through established commercial channels, and (c) components be. assembled as modules to allow replacement or substitution as units without interference with other components. The Portable Presentation Package is only slightly larger than an attaché case, weighs 23 pounds, includes camera with light meter, projector with remote controls and supplementary lenses, projection screen, tape recorder and the necessary power cords and mirrors, and additional film and magnetic tapes. Descriptions and drawings are presented in the report.
