Effects of virtual agent and object representation on experiencing exhibited artifacts
- Virtual embodied guides elicit a higher sense of spatial as well as social presence and appear more credible to users than virtual audio guides.
Display Omitted
AbstractWith the emergence of speech-controlled virtual agents (VAs) in consumer devices such as Amazon’s Echo or Apple’s HomePod, we have seen a large public interest in related technologies. While most of the current interactive ...
Blowing in the wind: Increasing social presence with a virtual human via environmental airflow interaction in mixed reality
- Importance of social presence in real-virtual human interactions.
- Physical-...

AbstractIn this paper, we describe two human-subject studies in which we explored and investigated the effects of subtle multimodal interaction on social presence with a virtual human (VH) in mixed reality (MR). In the studies, participants ...
Intelligent interaction and uncertainty visualization for efficient drusen and retinal layer segmentation in Optical Coherence Tomography
- Developed semi-automated tools for correcting retinal layer and drusen segmentation.
Display Omitted
AbstractConvolutional neural networks (CNNs) represent the state of the art for fully automated medical image segmentation. However, few works have combined CNNs with interactive user feedback in order to verify and, where necessary, correct ...

- Early detection of regional anomalies in myocardial motion for patients after the heart-transplant operation.
Display Omitted
AbstractA heart-transplanted patient is at risk of developing several complications such as rejection, which is one of the leading causes of deaths in the first year after the transplant. The regional myocardial motion is known to be depressed ...
Voxel-based edge bundling through direction-aware kernel smoothing
- The 10k edges represented in 10k voxels still allow for an interactive analysis.
Display Omitted
AbstractRelational data with a spatial embedding and depicted as node-link diagram is very common, e.g, in neuroscience, and edge bundling is one way to increase its readability or reveal hidden structures. This article presents a 3D extension ...
Automatic extraction and synthesis of regular repeatable patterns
- Automatic method capable of synthesizing regular repeating patterns in images.
- ...
Display Omitted
AbstractTextures made of regular repeating patterns are ubiquitous in the real world, most notably in man-made environments. They are defined by the presence of a repeating element, which can show a significant amount of random variations, non-...

AbstractInteraction in virtual reality (VR) environments (e.g. grasping and manipulating virtual objects) is essential to ensure a pleasant and immersive experience. In this work, we propose a visually realistic, flexible and robust grasping ...
Fast collision detection between high resolution polygonal models
- We use the EBP-Octree data structure to detect colliding triangles very complex scenarios.
Display Omitted
AbstractIn this paper, we address the problem of collision detection between very high resolution polygonal models. We propose an approach that uses the EBP-Octree data structure in a single-core CPU architecture. The algorithm manages a set ...
Transient instant radiosity for efficient time-resolved global illumination
- We generalize the classic work of instant radiosity, which is very suitable for parallelism in the GPU, to transient state.
