目的：我们的目标是评估显示技术对图像大小感知的影响程度。背景：研究表明，图像是否立体显示、用户的视角是否被跟踪以及给定显示器的视野等因素都会影响用户对显示图像中尺度的感知。方法：参与者通过将他们的手之间的距离与差距宽度相匹配来直接估计间隙的大小，并判断他们在三种显示技术的五种常见实现方式之一中畅通无阻地通过差距的能力结果：两个头戴式显示器[HMD]和一个背投影屏幕的间隙宽度的两个措施是类似的两个HMD条件和背投影与立体和跟踪。对于没有跟踪的显示器，立体和单眼条件彼此不同，单眼观看显示低估的size.Conclusions：显示技术，能够立体显示和跟踪用户的观点是有益的，因为感知的大小并不不同于现实世界的估计。随着显示条件的变化和不同显示技术的可用性不断增长，对不同显示技术的评估是必要的。应用：这些发现对于那些使用显示技术进行研究、商业和培训的人来说很重要，因为显示图像在预期的尺度上被感知是很重要的。
Objective: Our goal was to evaluate the degree to which display technologies influence the perception of size in an image.Background: Research suggests that factors such as whether an image is displayed stereoscopically, whether a user's viewpoint is tracked, and the field of view of a given display can affect users' perception of scale in the displayed image.Method: Participants directly estimated the size of a gap by matching the distance between their hands to the gap width and judged their ability to pass unimpeded through the gap in one of five common implementations of three display technologies (two head-mounted displays [HMD] and a back-projection screen).Results: Both measures of gap width were similar for the two HMD conditions and the back projection with stereo and tracking. For the displays without tracking, stereo and monocular conditions differed from each other, with monocular viewing showing underestimation of size.Conclusions: Display technologies that are capable of stereoscopic display and tracking of the user's viewpoint are beneficial as perceived size does not differ from real-world estimates. Evaluations of different display technologies are necessary as display conditions vary and the availability of different display technologies continues to grow.Applications: The findings are important to those using display technologies for research, commercial, and training purposes when it is important for the displayed image to be perceived at an intended scale.
