This paper describes the development of an immersive VR application that lets visual artists quickly visualize and prototype their pictorial design ideas in virtual environments. First, the design requirements are outlined and then the implementation of the application prototype in Unreal Engine 4 is explained. We perform preliminary user tests and discuss the feedback, as well as further improvements...
We anticipate advancements in mixed reality device technology which might benefit driver-car interaction scenarios and present a simulated diminished reality interface for car drivers. It runs in a custom driving simulation and allows drivers to perceive otherwise occluded objects of the environment through the car body. We expect to obtain insights that will be relevant to future real-world applications...
Through their experience with the ICERT REU program at the Texas Advanced Computing Center (TACC), two undergraduate students from the University of Puerto Rico and the University of Florida have initiated a collaboration between their home institutions and TACC exploring the possibility of using immersion to simulate perceptual disturbances. Perceptual disturbances are subjective in nature, and difficult...
This paper proposes an interactive annotation technique for 360° videos that allows the use of traditional video editing techniques to add content to immersive videos. Using the case study of immersive journalism the main objective is to diminish the entry barrier for annotating 360° video pieces, by providing a different annotation paradigm and a set of tools for annotation. The spread of virtual...
Modern microprocessors have a number of cores and complicated structures, such as multi-level caches. Behavior analysis of modern complicated processors is important for software performance optimizations, processor architecture researches, and education purposes. Currently, a number of tools are available for checking the behavior of processors such as processor simulators, debuggers and profilers...
In this poster, we introduce the notion of using LCD panels for controlling the level of immersion provided by head-mounted displays (HMDs). We propose replacing the cowling around typical “ski-goggle” type HMDs with LCD panels of the type used in commodity active-stereo glasses used in movie theaters. The panels can be controlled using very simple stand-alone circuitry and/or a micro-controller to...
In this paper, an interactive holographic system, realized with the aim of creating, exchanging, discussing and disseminating cultural heritage information, is presented. By using low-cost and off-the-shelf devices, the system provides the visitors with a 'floating' computer generated representation of a virtual cultural artefact that, unlike the real one, can be examined in detail through a touchless...
For decades Virtual Reality (VR) has remained out of our offices and everyday workflows due to its high cost, its custombuilt nature, and its often narrow design for highly specific tasks. These characteristics create a very high entry barrier for most users to use VR technology. Users typically had to be well funded, possess a high degree of expertise, spend weeks of effort porting VR capable software,...
Layperson's knowledge on climate change is highly relevant for the communication and public acceptance of climate policy. However, international surveys demand considerable efforts. As an alternative, player statistics obtained in games with a purpose may circumvent costly and self-aware survey settings, and allow collecting longitudinal measures. The social media game Climate Quiz is presented as...
Multi-projector systems for VR applications require complex infrastructure composed of several projectors and computers. Management of this complex structure is a challenge and requires expert personnel to keep it operational. In this paper we propose a flexible, mobile, off-the-shelf computing platform, targeted at the development of multi-projector displays algorithms. The goal is to achieve a fast...
Field trip and on-site detection is widely regarded as an important part of the Earth and environmental sciences. However, the real field trips, due to the complexity of the real environment can not be implemented. This article aims to establish a teaching using virtual trips laboratory characteristics of the modelbased on virtual field trips to design appropriate teaching modules, and use java 3d...
The time course and the distribution of visual attention are powerful measures for the evaluation of the usability of products. Eye tracking is thus an established method for evaluating websites, software ergonomy or modern cockpits for cars or airplanes. In most cases, however, the point of regard is measured on 2D products. This article presents work that uses an approach to measure the point of...
Electronic games have an important role in the human development so we can face the world of constantly changing technologies. Considering that the most of games is grounded in the interaction through visual elements and that the most of alternate games for blind is less attractive to non-blind people, we have developed a prototype of a 3D environment with dense sound experience and haptic feedback...
In this paper, we report the first step of our ongoing research toward the creation of an intuitive and interactive environment for manipulating and analyzing geological datasets. This first step of our project aimed at the development of a manipulation system through the employment of haptic sense and gesture detection, into a virtual environment. The developed prototype integrates stereoscopic interactive...
Virtual reality has achieved an adequate level of development for it to be considered in innovative applications such as education, training, and research in higher education. Virtual reality offers both opportunities and challenges for the educational sector. One of the challenges of virtual reality technology is the costs associated which have been unaffordable for educational institutes. However,...
Potential of nonverbal communication as the communication medium between multiuser 3D virtual worlds and real environment are attracting the interest of many researchers around the world. Driven by the motivation, we explored the possibilities of integrating haptic interactions with Linden Lab's multiuser online virtual world, Second Life. We developed an add-on to the Second Life communication channel...
Mixed reality techniques have high potential to support the development of complex systems that operate in a real world environment, especially mechatronic systems. In our paper we present the Mixed Reality in the Loop design process that enables a seamless progression from an initial virtual prototype to the final system along the mixed reality continuum.
Stroke is the number one cause of severe physical disability in the UK. Recent studies have shown that technologies such as virtual reality and imaging can provide an engaging and motivating tool for physical rehabilitation. In this paper we summarize previous work in our group using virtual reality technology and webcam-based games. We then present early work we are conducting in experimenting with...
The Gold Museum, in Bogota, Colombia, displays the largest collection of pre-Hispanic gold artifacts in the world and it has been renovated recently. With funds from the Colombian Government, we have created a multimodal experience that allows visitors to touch, hear, and see small artifacts. Here we present a description of this demo, its functionality, and technical requirements.
The paper calls for further innovations in the field of swarm intelligence, and presents an idea of using virtual flock(s) in a virtual room as a controller. Then, to demonstrate the viability of the idea, a working prototype is constructed where the controller is used to guide a ldquocreaturerdquo through a nontrivial corridor.
