In large software projects, it can be hard to understand the actual architecture of the implemented software systems if current design documents are outdated or do not exist at all. For systems based on the OSGi component specification, which are used to build quite large applications with back-end and front-end services, tools for visualizing the actual architecture can help to understand the system...
In recent years, Japanese tea ceremony has become increasingly popular outside of Japan. In Japan, there are many tea ceremony facilities (called chashitsu). However, there is not enough number of both chashitsu, and tea masters outside of Japan. In this paper, we propose virtual chashitsu that allows remotely located tea masters and students to practice Otemae (tea-serving manners) by using a common...
Digital recreations of historical sites and events are important tools both for academic researchers [6,7] and for public interpretation [7,9]. Current 3D visualization and VR technologies enable these recreations to be increasingly immersive and engaging [10,14]. This poster describes a case study based on a mid-twentieth century Chester dance hall, examining the possibilities and limitations of...
As everyone knows, the time of virtual reality has come, how to control and correct use of VR has become a significant topic. "In the era of virtual reality better humancomputer interaction", "virtual reality interactive context and traditional context where is the difference in space", "touch interactive virtual reality experience what? Through the manmachine interface design,...
This paper investigates the relationship between audio models for Virtual Reality (VR) video with respect to the senses of immersion and realism that each model delivers. Mono, Stereo, 5.1 Surround Sound, and a Virtual Spatialised Position configuration was developed for testing in a VR music video and evaluated with a user study. Participants experienced the VR video with these differing audio models...
In this paper we describe a cyberspace of scientific papers, in which the most cited and significant documents are represented by a large size and the distance between documents is proportional to their semantic similarity. A new measure of semantic similarity of documents is proposed that is determined by the maximum correlation between explicit and implicit connectivity of the documents. A new science...
This work brings a Systematic Review on the use of Virtual Reality in Fetal Medicine in order to recover the state of the art on the use of Virtual Reality tools in Fetal Medicine and also which Fetal Medicine areas has been focus of Virtual Reality application. The keywords “Virtual Reality” and “Fetal Medicine”, “Virtual Reality” and “Fetus” were used in both Portuguese and English and the “And”...
The appearance of MOOCs brings a lot of attentions. Although MOOCs provide the people with more learning opportunities and conditions, there are some disadvantages, such as the practice of the skills and the difficulties in the understanding of the key notes due to the lack of the interaction between the teacher and the students. Virtual reality technology brings the chance to solve these problems...
Normal adult becomes memory decline when increasing age. Memory decline can change from normal aging to mild cognitive impairment (MCI) and then Alzheimer's disease dementia. In order to reduce the risk of dementia, the cognitive training or brain training is needed. Cognitive training can stimulate the ability of normal person's memory for keeping ability of memory prompt when increasing age. Virtual...
This paper presents a framework which allows urban planners to navigate and interact with large datasets fused with social feeds in real-time, enhanced by a virtual reality (VR) capability, which further promotes the knowledge discovery process and allows to interact with urban data in natural yet immersive way. A challenge in urban planning is making decisions based on datasets which are many times...
Fluid dynamics simulation is often repeated while changing conditions, and therefore we need to compare a large amount of results. In order to compare results under different conditions, it is effective to overlap the streamlines generated from each condition in a single 3D space. Streamline is a curved line which represents a wind flow. This paper presents a technique to automatically select and...
360° video, supporting the ability to present views consistent with the rotation of the viewer's head along three axes (roll, pitch, yaw) is the current approach for creation of immersive video experiences. Nevertheless, a more fully natural, photorealistic experience — with support of visual cues that facilitate coherent psycho-visual sensory fusion without the side-effect of cyber-sickness — is...
Augmented feedback has been shown to improve interaction in virtual environments and to facilitate motor learning. Recent studies proposed this type of feedback to guide users, to highlight specific areas or to help them to perform a specific task. They can follow a path, pass through specific waypoints or even mimic an avatar. However these approaches do not show the gap between learners' performance...
According to the latest trends, users prefer to acquire knowledge through unconventional streams, using cumulative senses (hearing, viewing, sensing). Access to informational data should be characterized through its ease of use, consistency and reliability. Libraries have become target spaces for the deployment of applications for Augmented and Virtual Reality worlds, due to their complexity of information...
This paper presents software visualization tool that utilizes the modified city metaphor to represent software system and related analysis data in virtual reality environment. To better address all three kinds of software aspects we propose a new layouting algorithm that provides a higher level of detail and position the buildings according to the coupling between classes that they represent. Resulting...
This work consists of the study of techniques of robotics and virtual reality to develop a simulator that can be used in robotics schools, having an adequate visualization and a simple and intuitive way of interaction. For this, a 3D virtual environment for robotics was developed. Virtual reality resources have been incorporated to improve the visualization and to facilitate the user interaction with...
Gait asymmetry, one of the hallmarks of post-stroke locomotion, often persists despite of gait rehabilitation interventions and negatively affects functional mobility. This pilot study examines the feasibility and instantaneous effects of real-time visual feedback provided in the form of a virtual avatar replicating on gait symmetry after stroke. Based on the results obtained from one chronic stroke...
This study explores the relationship between the visual feedback of one's own limb and the own-body perception. Several studies have shown the importance of visual mirror feedback in remitting pain and restoring the sense of body ownership in some phantom limb pain patients. Using mixed reality, own limb visual feedback is removed and body perception and thermal sensitivity is probed in order to investigate...
Hemispatial neglect is common after stroke and associated with poor functional recovery and social return. Among various possible treatments for neglect, prism adaptation therapy has been known to be effective to promote the recovery from neglect. However, the conventional prism therapy using a prism glass and real object has a few shortcomings. Prism lens has to be changed to adjust the degree of...
Virtual Reality applications for integrated cognitive and motor stroke rehabilitation show promise for providing more comprehensive rehabilitation programs. However, we are still missing evidence on its impact in comparison with standard rehabilitation, particularly in patients with cognitive impairment. Additionally, little is known on how specific stimuli in the virtual environment affect task performance...
