Shiftly: A Novel Origami Shape-Shifting Haptic Device for Virtual Reality.

We present a novel shape-shifting haptic device, Shiftly, which renders plausible haptic feedback when touching virtual objects in Virtual Reality (VR). By changing its shape, different geometries of virtual objects can be approximated to provide haptic feedback for the user's hand. The device employs only three actuators and three curved origamis that can be programmatically folded and unfolded to create a variety of touch surfaces ranging from flat to curved.

Compressing VR: Fitting Large Virtual Environments within Limited Physical Space.

In practice, real-world physical workspaces and technological limitations restrict the free and unlimited exploration of an arbitrary large-scale virtual environment. This article provides an overview of the existing approaches and techniques for enlarging the walkable virtual space. The authors specifically focus on the methods that use spatial manipulation for spatial compression because it is one of the most promising, but underexplored methods for nonintrusive user redirection in a limited physical space.
