Virtual Replicas for Remote Assistance in Virtual and Augmented Reality
TLDR
Two approaches that use Virtual Reality (VR) or Augmented Reality (AR) for the remote expert, and AR for the local user, each wearing a stereo head-worn display are introduced.
ParaFrustum: visualization techniques for guiding a user to a constrained set of viewing positions and orientations
TLDR
Two visualization techniques for virtual or augmented reality that guide a user to assume one of the poses defined by a ParaFrustum are described, and the results of a user study measuring the performance of these techniques are presented.
Remote collaboration in AR and VR using virtual replicas
TLDR
This work demonstrates an approach that uses Virtual Reality (VR) or Augmented Reality (AR) for the remote expert, and AR for the local user, each wearing a stereo head-worn display (HWD).
Travel in large-scale head-worn VR: Pre-oriented teleportation with WIMs and previews
We demonstrate an interaction technique that allows a user to point at a world-in-miniature representation of a city-scale virtual environment and perform efficient and precise teleportation by
A user interface for assistive grasping
TLDR
A user interface which allows the user to combine the speed and convenience of offline preplanned grasps with the versatility of an online planner, and only four commands are necessary to control the entire grasping pipeline.
Hands-Free Interaction for Augmented Reality in Vascular Interventions
TLDR
This work demonstrates hands-free interaction techniques that use voice and head tracking to allow the physician to interact with 3D virtual content on a head-worn display while making both hands available intraoperatively.
Providing Assistance for Orienting 3D Objects Using Monocular Eyewear
TLDR
A novel visualization approach and three additional visualizations representing different paradigms for guiding unconstrained manual 3DOF rotation, targeting smaller field-of-view lightweight monoscopic HWDs, such as Google Glass, are designed and implemented.
[POSTER] Interactive Visualizations for Monoscopic Eyewear to Assist in Manually Orienting Objects in 3D
TLDR
This work describes four interactive rotation guidance visualizations for tracked objects intended for monoscopic head-worn displays, such as Google Glass, and explores alternatives to registered overlays.
Collaborative Virtual Reality for Low-Latency Interaction
TLDR
This work presents a multi-user virtual reality system that supports interactions of both symmetric and asymmetric users, and is currently applying this approach to motor rehabilitation, in which a therapist and patient work together.
Towards a Platform for Smart City-Scale Cognitive Assistance Applications
TLDR
CognitiveAR is described, a system that seamlessly interfaces AR devices with smart city environments that enable multi-user cognitive assistance applications that require real-time sensor data from the environment and computing resources for low-latency video processing.
