Summary: 
This paper proposed the advantages of using a 2D/3D hybrid imagery system over the use of 3D by itself. A hybrid imagery system was created by projecting a 3D (stereo) image in between and overlapping onto two adjacent 2D images. The negative effect where 2D and 3D images overlap was studied and resolved. Then sensations subject experienced from the visual cues under the different conditions were attained. Participant's sensations while looking at the different forms of imagery on both a flat screen and a flat/inclined screen combination were then attained. The data for the 2D/3D hybrid system were compared with that attained for a 3D image system on its own (without 2D images). Results indicate that there are benefits to using a 2D/3D hybrid system over 3D by itself.
