Consequences of Incorrect Focus Cues in Stereo Displays.
暂无分享,去创建一个
Conventional stereo displays produce images in which focus cues - blur and accommodation - are inconsistent with the simulated depth. We have developed new display techniques that allow the presentation of nearly correct focus. Using these techniques, we find that stereo vision is faster and more accurate when focus cues are mostly consistent with simulated depth; furthermore, viewers experience less fatigue when focus cues are correct or nearly correct.
