Abstract : A review of volumetric and stereoscopic display devices revealed no commanding reasons for their adoption in complex man-machine data processing systems. Claimed advantages are specific to particular system tasks, and no set of requirements has yet been identified that requires the 3-D displays. Methods of presenting multidimensional information on 2-D surfaces appear to be generally satisfactory and far less expensive. Certain specific disadvantages of the new 3-D displays have been considered. Many persons would have difficulty in their use from imperfect stereoscopic vision. The display equipment itself would have to be built to closer and more costly tolerance to provide increased registration to overcome certain inherent weaknesses, such as difficulty in generating suitable symbols in a volume, and to meet problems of reading out target data.
