We developed a novel interaction technique that allows virtual reality (VR) users to experience “weight” when hefting virtual, weightless objects. With this technique the perception of weight is evoked via constraints on the speed with which objects can be lifted. When hefted, heavier virtual objects move slower than lighter virtual objects. If lifters move faster than the lifted object, the object will fall. This constraint causes lifters to move slowly when lifting heavy objects. In two studies we showed that the size-weight illusion (SWI) is evoked when this technique is employed. The SWI occurs when two items of identical weight and different size are lifted and the smaller item is perceived as heavier than the larger item. The persistence of this illusion in VR indicates that participants bring their real-world knowledge of the relationship between size and weight to their virtual experience, and suggests that our interaction technique succeeds in making the visible tangible.

使视觉有形：在 VR 中用提升速度限制代替物体重量

我们开发了一种新颖的交互技术，可以让虚拟现实 (VR) 用户在举起虚拟的失重物体时体验“重量”。通过这种技术，可以通过对物体举起速度的限制来唤起对重量的感知。举重时，较重的虚拟对象比较轻的虚拟对象移动得慢。如果提升者的移动速度比被提升的物体快，物体就会下落。这种限制会导致举重者在举重物时移动缓慢。在两项研究中，我们表明当采用这种技术时会引起大小重量错觉 (SWI)。当两个重量相同但尺寸不同的物品被提起并且较小的物品被认为比较大的物品重时，就会发生 SWI。
