Visually Induced Motion Sickness Estimation and Prediction in Virtual Reality using Frequency Components Analysis of Postural Sway Signal
(The Eurographics Association, 2015)The paper proposes a method for estimating and predicting visually induced motion sickness (VIMS) occurring in a navigation task in a 3D immersive virtual environment, by extracting features from the body postural sway ... -
Global Landmarks Do Not Necessarily Improve Spatial Performance in Addition to Bodily Self-Movement Cues when Learning a Large-Scale Virtual Environment
(The Eurographics Association, 2015)Comparing spatial performance in different virtual reality setups can indicate which cues are relevant for a realistic virtual experience. Bodily self-movement cues and global orientation information were shown to increase ... -
An HMD-based Mixed Reality System for Avatar-Mediated Remote Collaboration with Bare-hand Interaction
(The Eurographics Association, 2015)We present a novel system for mixed reality based remote collaboration system, which enables a local user to interact and collaborate with another user from remote space using natural hand motion. Unlike conventional system ... -
Development of Encountered-type Haptic Interface that can Independently Control Volume and Rigidity of 3D Virtual Object
(The Eurographics Association, 2015)This paper describes the development of an encountered-type haptic interface that can independently present the physical characteristics of 3D virtual objects, such as shape and rigidity, in the real world. This interface ... -
Analysis of Depth Perception with Virtual Mask in Stereoscopic AR
(The Eurographics Association, 2015)A practical application of Augmented Reality (AR) is see-through vision, a technique that enables a user to observe an inner object located behind a real object by superimposing the virtually visualized inner object onto ... -
Hybrid Eye Tracking: Combining Iris Contour and Corneal Imaging
(The Eurographics Association, 2015)Passive eye-pose estimation methods that recover the eye-pose from natural images generally suffer from low accuracy, the result of a static eye model, and the recovery of the eye model from the estimated iris contour. ... -
Ring-shaped Haptic Device with Vibrotactile Feedback Patterns to Support Natural Spatial Interaction
(The Eurographics Association, 2015)Haptic feedback devices can be used to improve usability, performance and cognition in immersive virtual environments (IVEs) and have the potential to significantly improve the user's virtual reality (VR) experience during ... -
An Evaluation of the Effects of Hyper-Natural Components of Interaction Fidelity on Locomotion Performance in Virtual Reality
(The Eurographics Association, 2015)Virtual reality (VR) locomotion techniques that approximate real-world walking often have lower performance than fully natural real walking due to moderate interaction fidelity. Other techniques with moderate fidelity, ... -
Physical Space Requirements for Redirected Walking: How Size and Shape Affect Performance
(The Eurographics Association, 2015)Redirected walking provides a compelling solution to explore large virtual environments in a natural way. However, research literature provides few guidelines regarding trade-offs involved in selecting size and layout for ... -
Fast Robust and Precise Shadow Algorithm for WebGL 1.0 Platform
(The Eurographics Association, 2015)This paper presents fast and robust per-sample correct shadows for WebGL platform. The algorithm is based on silhouette shadow volumes and it rivals the standard shadow mapping performance. Our performance is usually ... -
Effectiveness of Spatial Coherent Remote Drive Experience with a Telexistence Backhoe for Construction Sites
(The Eurographics Association, 2015)In this paper, a spatial coherent remote driving system was designed and implemented to operate a telexistence backhoe over a wireless network. Accordingly, we developed a 6 degrees of Freedom (DOF) slave robot that can ... -
How to Time Travel in Highly Immersive Virtual Reality
(The Eurographics Association, 2015)What would it be like to be able to time travel to the past, meet your previous self, and override your previous actions in order to achieve a better outcome? While we cannot (yet?) achieve physical time travel, digital ... -
Bimanual Haptic Simulation of Bone Fracturing for the Training of the Bilateral Sagittal Split Osteotomy
(The Eurographics Association, 2015)In this work, we present a haptic training simulator for a maxillofacial procedure comprising the controlled breaking of the lower mandible. To our knowledge the haptic simulation of fracture is seldom addressed, especially ... -
Mutual Proximity Awareness in Immersive Multi-User Virtual Environments with Real Walking
(The Eurographics Association, 2015)Are users aware of each other in an immersive multi-user virtual environment if they cannot see or hear each other? We present a study on users' awareness of other users who share the same physical space. The goal of our ... -
Development of Mutual Telexistence System using Virtual Projection of Operator's Egocentric Body Images
(The Eurographics Association, 2015)In this paper, a mobile telexistence system that provides mutual embodiment of user's body in a remote place is discussed. A fully mobile slave robot was designed and developed to deliver visual and motion mapping with ... -
R-V Dynamics Illusion: Psychophysical Phenomenon Caused by the Difference between Dynamics of Real Object and Virtual Object
(The Eurographics Association, 2015)In Mixed-Reality (MR) space, it appeared that the sense of weight can be affected by a MR visual stimulation with a movable portion. We named this psychophysical influence caused by the difference between dynamics of the ... -
Roles in Collaborative Virtual Environments for Training
(The Eurographics Association, 2015)In this paper we present a novel approach to role modelling for Collaborative Virtual Environments with an Action Oriented Scenario Engine. Our role model is able to take into account different data about the actions such ... -
Influence of Path Complexity on Spatial Overlap Perception in Virtual Environments
(The Eurographics Association, 2015)Real walking in large virtual indoor environments within a limited real world workspace requires effective spatial compression methods. These methods should be unnoticed by the user. Scene manipulation that creates overlapping ... -
The Stretchable Arms for Collaborative Remote Guiding
(The Eurographics Association, 2015)The help of a remote expert to guide an agent in performing a physical task can be advantageous in many ways: saving time and money by avoiding travel, and thus increasing the rate of intervention. In many situations, the ... -
Yther: A Proposal and Initial Prototype of a Virtual Reality Content Sharing System
(The Eurographics Association, 2015)There are many virtual reality development tools, but we argue that none has solved the disparate problems of ease of content creation, openness of access for developers and broad support for a variety of immersive and ...
