N2 - Previous work in VR has demonstrated how individual physical objects can represent multiple virtual objects in different locations by redirecting the user's hand. We show how individual objects can represent multiple virtual objects of different sizes by resizing the user's grasp. We redirect the positions of the user's fingers by visual translation gains, inducing an illusion that can make physical objects seem larger or smaller. We present a discrimination experiment to estimate the thresholds of resizing virtual objects from physical objects, without the user reliably noticing a difference. The results show that the size difference is easily detected when a physical object is used to represent an object less than 90% of its size. When physical objects represent larger virtual objects, however, then scaling is tightly coupled to the physical object's size: smaller physical objects allow more virtual resizing (up to a 50% larger virtual size). Resized Grasping considerably broadens the scope of using illusions to provide rich haptic experiences in virtual reality.
