Holovision (www.holovision.com) is a patented technology that can create high-resolution, large-scale, moving three-dimensional images that can be viewed with full parallax by people in different locations without special eyewear.
Further, Holovision does not have a very restrictive viewing zone, does not produce only transparent images, does not require coherent light, and does not require liquid movement to adjust lens shape. In this section, we first provide a conceptual overview of Holovision and then discuss the details of alternative means for operationalizing Holovision .
Figure 1, below, provides a conceptual overview of how a screen using HolovisionTM technology can replicate the light beam content and angles that two viewers would see from real-world objects. The left side of Figure 1 shows a top-down cross-sectional perspective of the two viewers, represented by two pairs of eyes, who are observing two three-dimensional spheres.
Approximate representations of the views seen by each of the four eyes are shown as dotted-line images above each eye. The combination of the two different perspectives for different eyes, from slightly-different angles, is called binocular disparity. Binocular disparity is an important cue for three-dimensional perception.
