Edge- and Eccentricity-Guided Foveated Path Tracing with Adaptive Russian Roulette
Towards an Augmented Reality System for Obstacle Avoidance in Agricultural Machinery
We present a work-in-progress AR system designed to support obstacle avoidance in agricultural vehicles. Static hazards such as wells, rocks, or ditches are often obscured by tall …
Foveated Path Tracing with Configurable Sampling and Block-Based Rendering
Path tracing offers high-fidelity rendering but remains impractical for real-time applications due to slow convergence and noise. We present a dynamic foveated path tracing …
A Unified Real-Time Spatial and Chromatic Foveated Rendering in VR
We present a real-time, gaze-contingent foveated rendering framework for virtual reality (VR) that integrates variable rate shading (VRS), foveated mipmap, and foveated color …
The Effect of Spatial Reference on Visual Attention and Workload during Viewpoint Guidance in Augmented Reality
Considering human capability for spatial orientation and navigation, the visualization used to support the localization of off-screen targets inevitably influences the …
Virtual Lenses as Embodied Tools for Immersive Analytics
Interactive lenses are useful tools for supporting the analysis of data in different ways. Most existing lenses are designed for 2D visualization and are operated using standard …
Effect of User Roles on the Process of Collaborative 2D Level Design on Large, High-resolution Displays:
Enhancement of Pointing Towards Non-Haptic Augmented Reality Interfaces by Increasing the Arm Position Sense
Interactive user interfaces in head-mounted Augmented Reality environments are not always projected onto a physical surface. However, operating such free-floating interfaces by …
Hybrid Mono-Stereo Rendering in Virtual Reality
Rendering for Head Mounted Displays (HMD) causes a doubled computational effort, since serving the human stereopsis requires the creation of one image for the left and one for the …

gSMOOTH: A Gradient Based Spatial and Temporal Method of Depth Image Enhancement
The depth images from RGB-D cameras contain a substantial amount of artifacts such as holes and flickering. Moreover, for fast moving objects in successive frames, we perceive …
Column Major Pattern: How Users Process Spatially Fixed Items on Large, Tiled Displays
Large, high-resolution displays demonstrated their effectiveness in lab settings for cognitively demanding tasks in single user and collaborative scenarios. The effectiveness is …
Towards Intelligent Interfaces for Mixed-Focus Collaboration
An Efficient Interpolation Approach for Low Cost Unrestrained Gaze Tracking in 3D Space
The Effect of Visual Distractors in Peripheral Vision on User Performance in Large Display Wall Systems
Temporal Filtering of Depth Images Using Optical Flow
We present a novel depth image enhancement approach for RGB-D cameras such as the Kinect. Our approach employs optical flow of color images for refining the quality of …
On Spatial Perception Issues In Augmented Reality Based Immersive Analytics
Beyond other domains, the field of immersive analytics makes use of Augmented Reality techniques to successfully support users in analyzing data. When displaying ubiquitous data …
