Haptic PIVOT: On-Demand Handhelds in VR

We present PIVOT, a wrist-worn haptic device that renders virtual objects into the user’s hand on demand. Its simple design comprises a single actuated joint that pivots a haptic handle into and out of the user’s hand, rendering the haptic sensations of grasping, catching, or throwing an object – anywhere in space. Un…

Mise-Unseen: Using Eye Tracking to Hide Virtual Reality Scene Changes in Plain Sight

Creating or arranging objects at runtime is needed in many virtual reality applications, but such changes are noticed when they occur inside the user’s field of view. We present Mise-Unseen, a software system that applies such scene changes covertly inside the user’s field of view. Mise-Unseen leverages gaze tracking…

DualPanto: A Haptic Device that Enables Blind Users to Continuously Interact with Virtual Worlds

We present a new haptic device that enables blind users to continuously interact with spatial virtual environments that contain moving objects, as is the case in sports or shooter games. Users interact with DualPanto by operating the me handle with one hand and by holding on to the it handle with the other hand. Each…

iTurk: Turning Passive Haptics into Active Haptics by Making Users Reconfigure Props in Virtual Reality

We present a system that complements virtual reality experiences with passive props, yet still allows modifying the virtual world at runtime. The main contribution of our system is that it does not require any actuators; instead, our system employs the user to reconfigure and actuate otherwise passive props. We demons…

Scenograph: Fitting Real-Walking VR Experiences into Various Tracking Volumes

When developing a real-walking virtual reality experience, designers generally create virtual locations to fit a specific tracking volume. Unfortunately, this prevents the resulting experience from running on a smaller or differently shaped tracking volume. To address this, we present a software system called Scenogra…

VirtualSpace - Overloading Physical Space with Multiple Virtual Reality Users

Although virtual reality hardware is now widely available, the uptake of real walking is hindered by the fact that it requires often impractically large amounts of physical space. To address this, we present VirtualSpace, a novel system that allows overloading multiple users immersed in different VR experiences into t…
