Digital images obtained through medical imaging techniques are viewed using different visualization applications (methods). Also with the help of these applications, the three dimensional (3D) models of the images are created. Usually, the visualization and modelling processes are executed by medical staff, using general purpose applications. Via the same applications operation planning is made, after...
Equipment such as head-mounted displays are now available for the average consumer at affordable prices. This promotes the usage of this equipment for content consumption and demonstrations, thus it becomes important to establish the best practices for using this technology, namely guidelines in what concerns the recommended exposure time. Therefore, the purpose of this work is to study the impact...
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...
Synesthesia is the act of experiencing one sense modality as another, e.g., a person may vividly experience flashes of colors when listening to a series of sounds. Recent technological advances in the Virtual and Augmented Reality field allow to induce such experiences due to the effect of presence achieved in the virtual environment. In this paper, we present initial results related to a particular...
In discussing the rationale behind the vision for JPEG Pleno and how the new standardization initiative aims to reinvent the future of imaging, the authors review plenoptic representation and its underlying practical implications and challenges in implementing real-world applications with an enhanced quality of experience.
Robotics is the field currently taking its place as a leading candidate for dramatic changes in everyday life. Advances in the past 10 years in sensing, actuator and power technologies have fuelled an explosion of opportunities in this exciting, and surprisingly affordable domain. Small Unmanned Aircraft Systems (drones) are being rapidly developed for research, public service, and commercial applications,...
This Keynote Paper provides overview of recent work in the areas of Augmented Cognition, Inclusive Design and Creative Technology Innovation conducted by SMARTlab and the Inclusive Design Research Centres of Ireland and Canada. Projects underway, including several Marie Curie Post-Doctoral projects in the area of Assistive Technologies for People with Intellectual Disabilities-Autism, have applied...
The aim of the proposed 360-degree virtual reality (VR) documentary explores questions of identity in the multi-ethnic environment of Taiwan, the connection to perception, tradition, and globalization, as well as how these in turn characterize culture in Taiwan as distinct in the region. The VR framework presented here was conceived by Richard Cornelisse for providing an installation of multi-dimensional...
This paper introduces a case in which cultural heritage is communicated by combining historical narrative with Mixed Reality (MR) technology. The art of representing intangible heritage and making abstract and complex transformations comprehensible with MR technology is being discussed through a case example. MR application Sanan seppä (“Wordsmith”) represents the history of the Protestant Reformation...
In this paper, we propose a novel method for image based object relighting through patch match warping and color transfer. According to our method, a pair of reference object images (A and B), without any knowledge of the 3D geometry or material information of the input object image, are needed. The input image has similar illumination condition as that of the reference image A. The reference image...
During the past couple years, several Chinese and Latin American research communities have established and strengthened notable collaborative ties, in the fields of urban computing, virtual reality and visualization. These endeavors culminate in 2016 as the Sino-Latin America Birds of a Feather (SLA-BOF) event at the International Conference on Virtual Reality and Visualization (ICVRV). In this event...
The aim of this paper is to reduce simulator sickness caused by the low refresh rate of display in smartphone-based VR system. Without regard to the improvement of hardware, the method proposed in this paper reduces simulator sickness by adding static symbol on the screen of the smartphone. A series of user-participation experiments were done to validate the effectiveness of the method. Participants'...
Hair is one of the most recognizable parts of a human body, which is essential for the digitization of compelling virtual avatars but also one of the most challenging to create. In this paper, we present a single-view hair modeling technique for generating visually plausible strand-based 3D hair models. This is made possible by an effective high-precision 2D strand tracing algorithm, which explicitly...
So far, recent local feature learning methods mainly concentrate upon gradient based image features (e.g., SIFT), lacking of necessary color information, which debases the accuracy with limited matching power and thus results in many false positive matches. Besides, the discriminative power of common color description methods is hampered by vast variations, typically illumination changes, partial...
This paper introduced a novel method for stereoscopic image creation in virtual reality system. In our method, the left and right images are created in a single camera space, and the image disparities are produced by a pair of matrices. Based on the analysis on the relations among disparity, perceived depth and deformation of perceived objects in a single camera space, disparity and perceived deformation...
This paper introduces a unique type of mixed reality system based on passive-haptic feedback, which enables its user to manipulate real objects with bare hands while seeing its counterpart in the HMD with more information attached. The system provides users in MR systems with a more realistic sense of touch and costs less money comparing to the active force feedback devices. In this paper, accuracy...
A major challenge in developing Mixed Reality (MR) applications is the lack of a generic framework that can be used for easy development of MR applications employing multimodal user interaction techniques. The main objective of having such framework is that, whenever needed, it should be possible to simply design and develop a complete MR application to provide an immersive user experience based on...
We present a new mixed reality approach to achieve tangible object manipulation with a single, fully portable, and self-contained device. Our solution is based on the concept of a “tangible volume.” We turn a tangible object into a handheld fish-tank display. Our approach, however, goes beyond traditional fish-tank VR in that it can be viewed from all sides, and that the tangible volume represents...
Cinematic virtual reality (VR) aims to provide immersive visual experiences of real-world scenes on head-mounted displays. Current cinematic VR systems support stereo cues, but not focus cues that are important for depth perception and comfortable viewing. We propose a new content representation, depth augmented stereo panorama (DASP), which permits generating light fields (LFs) across the observer's...
Falls are a leading cause of injury and mortality among adults over the age of 65 years. Given the strong relation between fear of falling and fall risk, identification of the mechanisms that underlie anxiety-related changes in postural control may pave the way to the development of novel therapeutic strategies aimed at reducing fall risk in older adults. First, we review potential mechanisms underlying...
