3D Reconstruction of Hand Postures by Measuring Skin Deformation on Back Hand
(The Eurographics Association, 2017)
In this research, we propose a method for reconstructing hand posture by measuring the deformation of the back of the hand with a wearable device. The deformation of skin on the back of the hand can be measured by using ...
Space-Time Maps for Virtual Environments
(The Eurographics Association, 2014)
Terrain image maps are widely used in 3D Virtual Environments, including games, online social worlds, and Virtual Reality systems, for controlling elevation of ground-bound travelers and other moving objects. By making use ...
The Effects of Avatars on Presence in Virtual Environments for Persons with Mobility Impairments
(The Eurographics Association, 2014)
The main question we ask is: How do avatars affect presence specifically for Persons with Mobility Impairments (PMIs)? For example, PMIs' deficits in the proprioceptive sense could affect their body perception in immersive ...
Blurry (Sticky) Finger: Proprioceptive Pointing and Selection of Distant Objects for Optical See-through based Augmented Reality
(The Eurographics Association, 2016)
Most AR interaction techniques are focused on direct interaction with close objects within one’s reach (e.g. using the hands). Interacting with distant objects, especially those that are real, has not received much attention. ...
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 ...
Towards Enabling More Effective Locomotion in VR Using a Wheelchair-based Motion Platform
(The Eurographics Association, 2013)
This paper addresses two questions relevant to the design of effective locomotion methods for VR using a novel wheelchair motion simulation interface. First, we investigate the extent to which people's ability to keep track ...
Evaluating and Comparing Game-controller based Virtual Locomotion Techniques
(The Eurographics Association, 2017)
The incremental hardware costs of virtual locomotion are minimized when the technique uses interaction capabilities available in controllers and devices that are already part of the VE system, e.g., gamepads, keyboards, ...
Short Paper: Comparing Virtual Trajectories Made in Slalom UsingWalking-In-Place and Joystick Techniques
(The Eurographics Association, 2011)
In this paper we analyze and compare the trajectories made in a Virtual Environment with two different navigation techniques. The first is a standard joystick technique and the second is the Walking-In-Place (WIP) technique. ...
Comparison and Evaluation of Viewpoint Quality Estimation Algorithms for Immersive Virtual Environments
(The Eurographics Association, 2015)
The knowledge of which places in a virtual environment are interesting or informative can be used to improve user interfaces and to create virtual tours. Viewpoint Quality Estimation algorithms approximate this information ...
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 ...
