• On the uncertain future of the volumetric 3D display paradigm.

      Blundell, Barry G.; University of Derby (Springer, 2017-03-16)
      Volumetric displays permit electronically processed images to be depicted within a transparent physical volume and enable a range of cues to depth to be inherently associated with image content. Further, images can be viewed directly by multiple simultaneous observers who are able to change vantage positions in a natural way. On the basis of research to date, we assume that the technologies needed to implement useful volumetric displays able to support translucent image formation are available and so primarily focus on other issues that have impeded the broad commercialization and application of this display paradigm. This is of particular relevance given the recent resurgence of interest in developing commercially viable, general purpose, volumetric systems. We particularly consider image and display characteristics, usability issues and identify several advantageous attributes that need to be exploited in order to effectively capitalize on this display modality.
    • Volumetric 3D displays.

      Blundell, Barry G.; Auckland University of Technology (Springer, 2016)
      Volumetric displays enable electronically processed images to be depicted within a transparent volume, and so they are able to occupy three spatial dimensions. A broad range of depth cues are inherently associated with such images, including the parallax and oculomotor cues. Accommodation-convergence breakdown and depth cue conflict are avoided. Here we review aspects of this display modality, identify various key characteristics, and refer to a number of exemplar technologies. Brief consideration is given to the formation of opaque images and the implementation of an ethereal form of image space.
