在2D桌面显示器上描绘的3D对象的尺寸的准确感知对于许多应用是重要的。用户是否感知到显示器上描绘的对象与可比较的真实的世界对象具有相同的尺寸还没有很好地理解。我们建议使用启示的判断作为衡量的方式描绘在桌面虚拟环境和真实的世界中的对象的感知大小。该方法涉及指示特定动作是否可以在给定环境中执行，使其成为可以跨不同显示技术使用的灵活措施。在两项研究中，我们通过要求用户在真实的世界和几何匹配的桌面虚拟环境中做出可供性判断来测试他们对尺寸的感知。在第一项研究中，用户判断他们是否可以抓住一个物体，在第二项研究中，他们判断他们是否可以通过一个开口适合他们的手。在这两个实验中，我们表明，用户认为在桌面虚拟环境中的对象的大小要小于在真实的世界。
Accurate perception of the size of 3D objects depicted on 2D desktop displays is important for many applications. Whether users perceive objects depicted on a display to be the same size as comparable real world objects is not well understood. We propose using affordances judgments as a way of measuring the perceived size of objects depicted in desktop virtual environments and the real world. The methodology involves indicating whether or not a particular action can be performed in a given environment, making it a flexible measure that can be used across different display technologies. In two studies, we test users' perceptions of size by asking them to make affordance judgments in both the real world and a geometrically matched desktop virtual environment. In the first study, users judge whether they can grasp an object and in the second study, they judge whether they can fit their hand through an opening. In both experiments we show that users perceive the size of objects in the desktop virtual environment to be smaller than in the real world.
