TechViz has been a supporter of Formula Student at KIT for several years reflecting the companys long-term commitment to enhance engineering and education by providing students with powerful VR system software to connect curriculum to real-world applications. Incorporating immersive visualisation and interaction environment into Formula Student vehicle design is proven to deliver race day success,...
Recent research indicates that users consistently underestimate depth judgments to Augmented Reality (AR) graphics when viewed through optical see-through displays. However, to our knowledge, little work has examined how AR graphics may affect depth judgments of real world objects that have been overlaid or annotated with AR graphics. This study begins a preliminary analysis whether AR graphics have...
In most of today projects, the digital data, knowledge and expertise required are so large that a single person is far from enough to achieve the best decisions. Many critical processes now require several people to share the project specific information as well as their own views to collectively converge towards a right conclusion. Touch tables are promising collaborative work interfaces, but require...
Design and engineering of space vehicles involve several different disciplines, each of which have specific research methodologies and software tools. Interaction among the physical analysis tools, as well as collaboration among teams, is a delicate and difficult subject of collaborative engineering research topics. This paper presents a solution based on a new technical and interaction design. We...
Creating a virtual reality application requires the use of a 3D engine. Most 3D engine don't support virtual reality hardware or have the special features needed to render images for head-mounted displays, stereoscopic walls or CAVEs. MiddleVR is a generic VR toolbox with the following goals: — add support for VR in 3D engines — speed-up the application creation process with high-level building blocks...
Haptic feedback is known to improve 3D interaction in virtual environments but current haptic interfaces remain complex and tailored to desktop interaction. In this paper, we introduce the “Elastic-Arm”, a novel approach for incorporating haptic feedback in immersive virtual environments in a simple and cost-effective way. The Elastic-Arm is based on a body-mounted elastic armature that links the...
In this demo, we share our findings in building real-time 3D experiences with consumer headsets so as to go beyond the first person shooter gaming usage for which they are designed. We address the key problems of such user experiences which are to isolate the user from his own body, have him lose contact with other people in the room and with the real world. To solve those issues we use an off-the-shelf...
The present paper describes the system to present a pseudo-walking sensation to a sitting participant. The vibration was added to the heel and toe to imitate cutaneous sensation of the sole during walking. The sound of footsteps was also provided to the participant through headphones simultaneously. In this sound presentation, we used a spatial sound of footsteps of another walker as well as own footstep...
Communication is a fundamental process in collaborative work. In natural conditions, communication between team members is multimodal. This allows for redundancy, adaptation to different contexts, and different levels of focus. In collaborative virtual environments, however, hardware limitations and lack of appropriate interaction metaphors reduce the amount of collaboration. In this poster, we propose...
We present a novel underwater VR game — Shark Punch — in which the user must fend off a virtual Great White shark with real punches in a real underwater environment. This poster presents our underwater VR system and our iterative design process through field tests with a user with disabilities. We conclude with proposed usability, accessibility, and system design guidelines for future underwater VR...
In this work, we report on a pilot study we conducted, and on a study design, to examine the effects and applicability of rotation gain in CAVE-like virtual environments. The results of the study will give recommendations for the maximum levels of rotation gain that are reasonable in algorithms for enlarging the virtual field of regard or redirected walking.
We draw from the domains of Visual Analytics and Augmented Reality to support a new form of in-situ interactive visual analysis. We present a Situated Analytics model, a novel interaction, and a visualization concept for reasoning support. Situated Analytics has four primary elements: situated information, abstract information, augmented reality interaction, and analytical interaction.
Symptoms of three-dimensional (3D) sickness, such as intoxication and eye fatigue, have been observed in subjects viewing 3D films and vary according to the image quality and visual environment. In addition, the influence of stereoscopic vision on the incidence of 3D sickness has not been explored sufficiently. Therefore, it is important to examine the safety of viewing virtual 3D content. The present...
Virtual reality is a good tool to design and assess urban projects and to study perception in cities. Climate perception significantly influences the perception and use of urban spaces; however, virtual urban environments are scarcely represented with different climatic aspects. In this paper, we study the role that visual cues (sky aspect, shadows, sun location, and light effects) specifically play...
AR (Augmented Reality) technology, which uses actual landscape photography captured with a camera on-site as a base and then overlays virtual objects on that landscape image, is valid for landscape simulation. In this study, we generate nightscape images by superimposing high-luminance segments (virtual objects) over darkening landscape i ages. They are adjusted due to dark adaption modification....
This paper proposes a 3D node localization method that uses cross-entropy method for the 3D modeling system. The proposed localization method statistically estimates the most probable positions overcoming measurement errors through iterative sample generation and evaluation. The generated samples are evaluated in parallel, and then a significant speedup can be obtained. We also demonstrate that the...
This document introduces a new application for rendering massive LiDAR point cloud data sets of interior environments within highresolution immersive VR display systems. Overall contributions are: to create an application which is able to visualize large-scale point clouds at interactive rates in immersive display environments, to develop a flexible pipeline for processing LiDAR data sets that allows...
EVE (Exercise in Virtual Environments) is an operational VR system designed for space, polar and submarine crews. This system allows crewmembers — living and working in artificial habitats- to explore immersive natural landscapes during their daily physical exercise, and experience presence in a variety of alternate environments. Using recent hardware and software, this innovative psychological counter-measure...
