- Determining the features of human binocular vision according to given disparity information has gained signicant interest with regard to 3-D-relevant elds. However, subjectively distinguishing the features is internally ambiguous owing to personal factors and external susceptibility due to viewingenvironmental factors. Moreover, high cost and low reproducibility of the subjective assessment method restricts its usability in numerous practical applications. To alleviate these problems, this paper presents a novel visual stimulus, namely layered random dot stereogram (LRDS), and hierarchical paradigm for vote ratings. Based on the guide depth information in LRDS, viewers could recognize considerably obvious feature points, and our two-step rating strategy enhanced the reliability and efciency of the viewing tests. The experiments prove that our approach successfully reects the effects of not only personal factors but also display factors on depth perception. Our approach would be benecial to the 3-D elds of human factor, viewer-interactive systems, and product performance evaluation.
