VRScenarioBuilder: Free-Hand Immersive Authoring Tool for Scenario-based Testing of Automated Vehicles

Sevinc Eroglu, Arthur Voigt, Benjamin Weyers, Torsten Wolfgang Kuhlen
2024 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)

Virtual Reality has become an important medium in the automotive industry, providing engineers with a simulated platform to actively engage with and evaluate realistic driving scenarios for testing and validating automated vehicles. However, engineers are often restricted to using 2D desktop-based tools for designing driving scenarios, which can result in inefficiencies in the development and testing cycles. To this end, we present VRScenarioBuilder, an immersive authoring tool that enables engineers to create and modify dynamic driving scenarios directly in VR using free-hand interactions. Our tool features a natural user interface that enables users to create scenarios by using drag-and-drop building blocks. To evaluate the interface components and interactions, we conducted a user study with VR experts. Our findings highlight the effectiveness and potential improvements of our tool. We have further identified future research directions, such as exploring the spatial arrangement of the interface components and managing lengthy blocks.

Design and Evaluation of a Free-Hand VR-based Authoring Environment for Automated Vehicle Testing

IEEE Conference on Virtual Reality and 3D User Interfaces 2021

Virtual Reality is increasingly used for safe evaluation and validation of autonomous vehicles by automotive engineers. However, the design and creation of virtual testing environments is a cumbersome process. Engineers are bound to utilize desktop-based authoring tools, and a high level of expertise is necessary. By performing scene authoring entirely inside VR, faster design iterations become possible. To this end, we propose a VR authoring environment that enables engineers to design road networks and traffic scenarios for automated vehicle testing based on free-hand interaction. We present a 3D interaction technique for the efficient placement and selection of virtual objects that is employed on a 2D panel. We conducted a comparative user study in which our interaction technique outperformed existing approaches regarding precision and task completion time. Furthermore, we demonstrate the effectiveness of the system by a qualitative user study with domain experts.

Rilievo: Artistic Scene Authoring via Interactive Height Map Extrusion in VR

Sevinc Eroglu, Patric Schmitz, Carlos Aguilera Martinez, Jana Rusch, Leif Kobbelt, Torsten Wolfgang Kuhlen
ACM SIGGRAPH 2020 Art Papers. Published in Leonardo Journal.

The authors present a virtual authoring environment for artistic creation in VR. It enables the effortless conversion of 2D images into volumetric 3D objects. Artistic elements in the input material are extracted with a convenient VR-based segmentation tool. Relief sculpting is then performed by interactively mixing different height maps. These are automatically generated from the input image structure and appearance. A prototype of the tool is showcased in an analog-virtual artistic workflow in collaboration with a traditional painter. It combines the expressiveness of analog painting and sculpting with the creative freedom of spatial arrangement in VR.

Fluid Sketching — Immersive Sketching Based on Fluid Flow

Sevinc Eroglu, Sascha Gebhardt, Patric Schmitz, Dominik Rausch, Torsten Wolfgang Kuhlen
Proceedings of IEEE Virtual Reality 2018

Fluid artwork refers to works of art based on the aesthetics of fluid motion, such as smoke photography, ink injection into water, and paper marbling. Inspired by such types of art, we created Fluid Sketching as a novel medium for creating 3D fluid artwork in immersive virtual environments. It allows artists to draw 3D fluid-like sketches and manipulate them via six degrees of freedom input devices. Different sets of brush strokes are available, varying different characteristics of the fluid. Because of fluid's nature, the diffusion of the drawn fluid sketch is animated, and artists have control over altering the fluid properties and stopping the diffusion process whenever they are satisfied with the current result. Furthermore, they can shape the drawn sketch by directly interacting with it, either with their hand or by blowing into the fluid. We rely on particle advection via curl-noise as a fast procedural method for animating the fluid flow.

Fluid Sketching: Bringing Ebru Art into VR

Sevinc Eroglu, Benjamin Weyers, Torsten Wolfgang Kuhlen
Mensch und Computer 2018 - Workshopband

In this interactive demo, we present our Fluid Sketching application as an innovative virtual reality-based interpretation of traditional marbling art. By using a particle-based simulation combined with natural, spatial, and multi-modal interaction techniques, we create and extend the original artistic work to build a comprehensive interactive experience. With the interactive demo of Fluid Sketching during Mensch und Computer 2018, we aim at increasing the awareness of paper marbling as traditional type of art and demonstrating the potential of virtual reality as new and innovative digital and artistic medium.
