Large high-resolution displays (LHRDs) provide an enabling technology to achieve immersive, isometrically registered, virtual environments. It has been shown that LHRDs allow better size judgments, higher collaboration performance, and shorter task completion times. This paper presents novel insights into human size perception using large-scale floor displays, in particular in-depth evaluations of size judgment accuracy, precision, and task completion time. These investigations have been performed in the context of six, novel applications in the domain of automotive production planning. In our studies, we used a 54-sqm sized LED floor and a standard tablet visualizing relatively scaled and true to scale 2D content, which users had to estimate using different aids. The study involved 22 participants and three different conditions. Results indicate that true to scale floor visualizations reduce the mean absolute percentage error of spatial estimations. In all three conditions, we did not find the typical overestimation or underestimation of size judgments.

大型高分辨率显示器（LHRD）提供了一种启用技术，可实现沉浸式，等距配准的虚拟环境。研究表明，LHRD可以进行更好的大小判断，更高的协作性能和更短的任务完成时间。本文介绍了使用大型地板显示器对人的大小感知的新颖见解，尤其是对大小判断准确性，精度和任务完成时间的深入评估。这些研究是在汽车生产计划领域的六个新颖应用的背景下进行的。在我们的研究中，我们使用了54平方米大小的LED地板和标准平板电脑来可视化相对缩放和真实缩放的2D内容，用户必须使用不同的辅助工具进行估算。该研究涉及22名参与者和三种不同情况。结果表明，按比例显示地板可视化效果可以减少空间估计的平均绝对百分比误差。在所有这三种情况下，我们都没有发现大小判断的典型高估或低估。
