Google Tango Outdoors. Augmented Reality for Underground Infrastructures
(The Eurographics Association, 2017)
Underground infrastructures, which support much of the services provided to citizens, have the peculiarity of not being directly visible. This leads to problems when making incursions for maintenance or creating new ...
A 3 Cent Recognizer: Simple and Effective Retrieval and Classification of Mid-air Gestures from Single 3D Traces
(The Eurographics Association, 2017)
In this paper we present a simple 3D gesture recognizer based on trajectory matching, showing its good performances in classification and retrieval of command gestures based on single hand trajectories. We demonstrate that ...
Single-Handed vs. Two Handed Manipulation in Virtual Reality: A Novel Metaphor and Experimental Comparisons
(The Eurographics Association, 2017)
In this paper we present a novel solution for single-handed deviceless object manipulation (e.g. picking/translating, rotating and scaling) in immersive visualization environments. The new method is based on degree of ...
User Interaction Feedback in a Hand-Controlled Interface for Robot Team Tele-operation Using Wearable Augmented Reality
(The Eurographics Association, 2017)
Continuous advancements in the field of robotics and its increasing spread across heterogeneous application scenarios make the development of ever more effective user interfaces for human-robot interaction (HRI) an extremely ...
Data Painter: A Tool for Colormap Interaction
(The Eurographics Association, 2017)
The choice of a mapping from data to color should involve careful consideration in order to maximize the user understanding of the underlying data. It is desirable for features within the data to be visually separable and ...
Exploring Online Learners' Interactive Dynamics by Visually Analyzing Their Time-anchored Comments
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
MOOCs (Massive Open Online Courses) are increasingly prevalent as an online educational resource open to everyone and have attracted hundreds of thousands learners enrolling these online courses. At such scale, there is ...
Watercolor Woodblock Printing with Image Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Watercolor paintings have a unique look that mixes subtle color gradients and sophisticated diffusion patterns. This makes them immediately recognizable and gives them a unique appeal. Creating such paintings requires ...
Flexible Live-Wire: Image Segmentation with Floating Anchors
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
We introduce Flexible Live-Wire, a generalization of the Live-Wire interactive segmentation technique with floating anchors. In our approach, the user input for Live-Wire is no longer limited to the setting of pixel-level ...
Interactive Generation of Time-evolving, Snow-Covered Landscapes with Avalanches
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
We introduce a novel method for interactive generation of visually consistent, snow-covered landscapes and provide control of their dynamic evolution over time. Our main contribution is the real-time phenomenological ...
Rendering and Extracting Extremal Features in 3D Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Visualizing and extracting three-dimensional features is important for many computational science applications, each with their own feature definitions and data types. While some are simple to state and implement (e.g. ...
