We present a complete hardware and software solution for integrating binocular eye tracking into current state-of-the-art lens-based Head-mounted Displays (HMDs) without affecting the user's wide field-of-view off the display. The system uses robust and efficient new algorithms for calibration and pupil tracking and allows realtime eye tracking and gaze estimation. Estimating the relative gaze direction...
We propose a system that enables dynamic 3D interaction with real and virtual objects using an optical see-through head-mounted display and an RGB-D camera. The virtual objects move according to physical laws. The system uses a physics engine for calculation of the motion of virtual objects and collision detection. In addition, the system performs collision detection between virtual objects and real...
We present a general toolbox for virtual reality (VR) research in the field of psychology. Our aim is to simplify the generation and setup of complicated VR scenes for researchers. Various study protocols about perception, attention, cognition and memory can be constructed using our toolbox. Here we specifically showcase a fully functional demo for change blindness phenomena.

In this study, we propose a VR system for allowing various types of interaction with virtual objects using an autostereoscopic mobile display and an accelerometer. The system obtains the orientation and motion information from the accelerometer attached to the mobile display and reflects them to the motion of virtual objects. It can present 3D images with motion parallax by estimating the position...
Marioneta is an installation for the Children's Museum of Pittsburgh which uses the Microsoft Kinect v2 to allow guests to embody a collection of antique puppets in a virtual environment. Final installation in the museum is shown in Fig 1. The focus is on creating an experience wherein elements in the world react to the users' actions through these puppets[1]. Puppet models in the experience are based...
Head-up displays (HUDs) have become common equipment in aircraft cockpits. One of the uses of HUDs is to provide a specific visual interface for pilots in the form of what is called a "tunnel-in-the-sky" (i.e. 3D geometry for the navigation path displayed on a flat screen). According to recent studies the "tunnel-in-the-sky" approach does not provide crucial advantages in comparison...
Effectively evaluating optical see-through (OST) head-mounted display (HMD) calibration is problematic and largely relies on feedback from the user. Studies evaluating OST HMD calibration, such as those by McGarrity, Tang, and Navab et al. [2, 3, 1], utilize user interaction methods, such as touch pads, to facilitate on-line evaluation and correction of calibration results. In all of these studies,...
3D applications appear in every corner of life in the current technology era. There is a need for an ubiquitous 3D input device that works with many different platforms, from head-mounted displays (HMDs) to mobile touch devices, 3DTVs, and even the Cave Automatic Virtual Environments. We present 3DTouch [1], a novel wearable 3D input device worn on the fingertip for 3D manipulation tasks. 3DTouch...
The long term objective of this research is to enable persons with disabilities to play VR games during aquatic rehabilitation [2] sessions. Unfortunately, there have been only a few research projects that have explored VR underwater use [3][1][4], and none of these have addressed rehabilitation. This research focuses on understanding and mitigating the associated usability, accessibility, and system...
Hearts and Minds: The Interrogations Project is an interactive Virtual Reality narrative performance developed in Unity for the CAVE2™ large-scale 320-degree panoramic virtual reality environment at the Electronic Visualization Lab (EVL) at the University of Illinois Chicago (UIC). The work provides an experience of true stories of abusive violence, battlefield torture and post-traumatic stress during...
A glove box simulator is presented for a safe and cost-effective training of the operators in the nuclear industry. The focus is on learning of the proper safety procedures and correct maintenance of a glove box in the presence of potentially radioactive substances. Two common situations are explored — operator working in the glove box and operator performing maintenance on it.
OSVR is a new open-source virtual reality platform that builds on and extends existing libraries. It provides a common ground for university and commercial research and development, enabling new development at any level to be rapidly tested and deployed in a full application stack. Devices are discovered and enumerated, with self-description data made available to applications for use in sensible...
Industry and services have a growing interest in prevention through design with regard to safety of machinery to avoid redesign after construction. A VR planning model of a future river lock has been developed and investigated for risk assessment support. Inspections using the model in 1:1 scale promoted safety analyses of the operational concept, identified hazards and planning flaws, and triggered...
An Augmented Reality (AR) composite layup tool was created using lo cost, off the shelf co ponents and software to prove and demonstrate the application of AR in a manufacturing environment. The project tested different tracking technologies in order to ascertain their practicality within an industrial environment. By developing an understanding of the challenges faced in implementing such an application,...
Rewarded at Laval Virtual 2014, the AccesSim project aims to develop a wheelchair simulator based on Virtual Reality (VR) and a dynamic force-feedback platform, which allows to experience and to evaluate the accessibility in complex urban or property environment. In order to address this issue, the dynamic force-feedback platform should provide haptic and vestibular feedback to various user profiles:...
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...
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...
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,...
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...
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...
