Investigating the Learnability of Immersive Free-Hand Sketching
(The Eurographics Association, 2010)Immersive modeling systems which allow for sketching and constructing three-dimensional product models receive growing interest from both academic research and industry [DBWB*00; FASM02; IWMS09; KAMD*08; KAML*01]. The ... -
Investigating the Manual View Specification and Visualization by Demonstration Paradigms for Visualization Construction
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Abstract Interactivity plays an important role in data visualization. Therefore, understanding how people create visualizations given different interaction paradigms provides empirical evidence to inform interaction design. ... -
Investigating the Role and Interplay of Narrations and Animations in Data Videos
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Combining data visualizations, animations, and audio narrations, data videos can increase viewer engagement and effectively communicate data stories. Due to their increasing popularity, data videos have gained growing ... -
Investigating the Role of Locus of Control in Moderating Complex Analytic Workflows
(The Eurographics Association, 2020)Throughout the last decade, researchers have shown that the effectiveness of a visualization tool depends on the experience, personality, and cognitive abilities of the user. This work has also demonstrated that these ... -
Investigating the Structural Validity of Virtual Reconstructions of Prehistoric Maltese Temples
(The Eurographics Association, 2005)The prehistoric temples found on the Maltese islands, dated from 3600 - 2500 BC, are unique examples of truly megalithic complexes. Although the temples can still be viewed today, they are unroofed. One of the major questions ... -
Investigating User Requirements and Usability of Immersive Three-dimensional Sketching for Early Conceptual Design - Results from Expert Discussions and User Studies
(The Eurographics Association, 2008)As immersive 3-d user interfaces reach broader acceptance, their use as sketching media is attracting both commercial and academic research. So far little is known about user requirements and cognitive aspects of immersive ... -
Investigation and Simulation of Diffraction on Rough Surfaces
(Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd., 2023)Simulating light–matter interaction is a fundamental problem in computer graphics. A particular challenge is the simulation of light interaction with rough surfaces due to diffraction and multiple scattering phenomena. To ... -
An Investigation into the design of an Interface for Interaction with a Virtual Environment representing a four-dimensional object
(The Eurographics Association, 2001)Five methods of mapping the input from a six-degrees-of-freedom input device to the set of rotations available in four-dimensional space are evaluated with respect to how well they can be used to perform four-dimensional ... -
Investigation of Dynamic View Expansion for Head-Mounted Displays with Head Tracking in Virtual Environments
(The Eurographics Association, 2014)Head mounted displays (HMD) are widely used for visual immersion in virtual reality (VR) systems. It is acknowledged that the narrow field of view (FOV) for most HMD models is the leading cause of insufficient quality of ... -
An Investigation of Optimal Light Source Setups for Photometric Stereo Reconstruction of Historical Coins
(The Eurographics Association, 2018)In this paper, we address the 3D reconstruction of historical coins by means of Photometric Stereo. We investigate the influence of the number and arrangement of lights to the reconstruction quality by comparing mean angular ... -
Investigative Visual Analysis of Global Terrorism
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Recent increases in terrorist activity around the world have made analyzing and understanding such activities more critical than ever. With the help of organizations such as the National Center for the Study of Terrorism ... -
Invisible Heritage - Analysis and Technology Digital Platform
(The Eurographics Association, 2021)In an era of rapid technological improvements, state-of-the-art methodologies and tools dedicated to protecting and promoting our cultural heritage should be developed and extensively employed to expand and enrich historical ... -
Invisible Interface for the Immersive Virtual World
(The Eurographics Association, 2001)Immersive projection technologies such as CAVE can generate a high presence virtual world. However, it is difficult for the user to experience the immersive virtual world in the real workplace, such as the design room or ... -
Invisible Long Arm Illusion: Illusory Body Ownership by Synchronous Movement of Hands and Feet
(The Eurographics Association, 2018)We feel as if a fake body is our own body by synchronicity between the fake body and the actual body (illusory body ownership) even if the body has a different shape. In our previous study, we showed that illusory body ... -
The Invisible Person - Advanced Interaction Using an Embedded Interface
(The Eurographics Association, 2003)In this paper we describe an advanced user interface enabling even playing games in an immersive virtual environment. There are no common input devices, users presence in the environment, movements, and body postures are ... -
Invisible Seams
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Surface materials are commonly described by attributes stored in textures (for instance, color, normal, or displacement). Interpolation during texture lookup provides a continuous value field everywhere on the surface, ... -
InVITe - Towards Intuitive Visualization of Iterations over Text
(The Eurographics Association, 2016)With InVITe, we are working towards intuitive visualization to support review of iterative modifications on text documents. In order to accomplish this, we perform simple matching of text snippets between the two versions ... -
The InViWo virtual agents
(Eurographics Association, 1999)The InViWo project aims at providing non-computer scientists with high-level tools to create inhabited virtual worlds, i.e. in which autonomous agents and avatars can interact. In this paper, we describe the agent model ... -
iPACKMAN: High-Quality, Low-Complexity Texture Compression for Mobile Phones
