An Evaluation of Holograms as Training and Job Aids

This study was concerned with an evaluation of holography in training and for job aids. Experimentation comparing holograms, line drawings, and photographs as methods of presenting visual information is reported. It appears that with the tasks used, holograms generally are as good as or better visual aids than either photographs or line drawings. The use of holograms tends to reduce errors rather than speed assembly time in assembly tasks. They also seem to enhance the discovery of errors when the subject is attempting to locate assembly errors in a construction. The results of this experimentation suggest that serious consideration should be given to the use of holography in the development of job aids and in training. Applications in technical documentation and storage relevant to the use of holograms as job aids are also considered.
