在过去的十年中，多点触摸表面已经变得司空见惯，许多研究人员和从业者描述了其自然的、类似物理的交互的好处。我们提出了一对研究，实证调查的心理物理效应的直接互动与物理和虚拟文物。我们使用的现象，动觉图形后，一个变化的理解后，一个物体的物理大小的一段时间后，暴露在一个物体的大小不同。我们的研究表明，虽然在使用物理文物时这种效果是鲁棒地可重现的，但在直接多点触摸桌面显示器上操作虚拟文物时，这种相同的效果并不表现出来。我们提供了定量的证据，表明我们对物理与虚拟对象的反应存在心理物理差异，并讨论了未来的研究方向，以探索可测量的现象，以评估虚拟屏幕上对象的物理变化的存在。
Over the past decade, multi-touch surfaces have become commonplace, with many researchers and practitioners describing the benefits of their natural, physical-like interactions. We present a pair of studies that empirically investigates the psychophysical effects of direct interaction with both physical and virtual artefacts. We use the phenomenon of Kinesthetic Figural After Effects-a change in understanding of the physical size of an object after a period of exposure to an object of different size. Our studies show that, while this effect is robustly reproducible when using physical artefacts, this same effect does not manifest when manipulating virtual artefacts on a direct, multi-touch tabletop display. We contribute quantitative evidence suggesting a psychophysical difference in our response to physical vs. virtual objects, and discuss future research directions to explore measurable phenomena to evaluate the presence of physical-like changes from virtual on-screen objects.
