“…As long as the accommodation shift remains within the DOF, accommodation is able to focus the reconstituted object sharply on the retina. 46 If screen disparity is increased up to an amount at which the resulting retinal defocus cannot be accounted for by the DOF, negative accommodation feedback directs accommodation and vergence (via accommodative-vergence) towards the display, thus away from the reconstituted object. As such, the accommodation response conflicts with the vergence response.…”

“…The issue of viewer comfort for stereoscopic displays is studied in detail in relatively few human factors publications [16][17][18][19] . However, a similar conclusion is drawn by all the studies: the amount of disparity in stereoscopic images should be limited to be within a defined comfortable range.…”

ABSTRACTStereoscopic images are hard to get right, and comfortable images are often only produced after repeated trial and error. The main difficulty is controlling the stereoscopic camera parameters so that the viewer does not experience eye strain or double images from excessive perceived depth. Additionally, for head tracked displays, the perceived objects can distort as the viewer moves to look around the displayed scene. We describe a novel method for calculating stereoscopic camera parameters with the following contributions:(1) Provides the user intuitive controls related to easily measured physical values. (2) For head tracked displays; necessarily ensures that there is no depth distortion as the viewer moves. (3) Clearly separates the image capture camera/scene space from the image viewing viewer/display space. (4) Provides a transformation between these two spaces allowing precise control of the mapping of scene depth to perceived display depth.The new method is implemented as an API extension for use with OpenGL, a plug-in for 3D Studio Max and a control system for a stereoscopic digital camera. The result is stereoscopic images generated correctly at the first attempt, with precisely controlled perceived depth. A new analysis of the distortions introduced by different camera parameters was undertaken.

“…The complaints of some viewers about visual discomfort such as eyestrain and associated symptoms including nausea and headaches present a barrier in the popularization of stereoscopic 3D technology. Some visual discomfort may occur due to excessive demand on the accommodation-vergence linkage, fast local and global motion, and various stereoscopic distortions [1,2,3,4,5,6].…”

The motion-in-depth is an important factor in measuring visual discomfort when watching stereoscopic 3D video since it changes accommodation and vergence at the same time. In this paper, we examine visual discomfort caused by motion-in-depth in terms of viewing time and display size in watching stereoscopic 3D video. The assessment methods for visual discomfort we used were a subjective test such as a questionnaire, and an objective test such as eye blink rate detection. The experimental results showed that visual discomfort increased in proportion with the speed of motion-in-depth and viewing time. We also found that the viewer's discomfort increased when watching stereoscopic 3D video on the smaller-sized display than on a larger-sized display.
