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...
Abstract art is a powerful medium of expression but simultaneously a very poor means of visual communication. In an effort to physically experiment with symbolic yet innovative thoughts or ideas in geometric, abstraction art, the researcher investigates the potential, value, and uses of building simple three-dimensional (3D) objective interpretations of reality available to touch.
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 poster presents the conceptual process of developing Itapeva 3D, a Virtual Reality (VR) archeology experience. It describes the technical spectrum of cyber-archeology process applied to the creation of a fully immersive and interactive virtual environment (VE), which represents Itapeva Rocky Shelter, a prehistoric archeological site in Brazil. The workflow starts with a real world data capture...
This project investigates the impact of a virtual zero gravity experience on the human gravity model. In the planned experiment, subjects are immersed with HMD and full body motion capture in a virtual world exhibiting either normal gravity or the apparent absence of gravity (i.e. body and objects floating in space). The study evaluates changes in the subjects' gravity model by observing changes on...
Virtual Reality technology has a promising future in the area of living space because of its capacity for deconstructing data of space and visualization. The article is mainly about the brand new ways of space designing and the application of intelligent home system based on virtual reality technologies. It describes the revolution this technology will bring in constructing a humanized, scientific,...
In this study, we investigated the difference of luxuriousness between real model house and web-based model house. Living room as the most important residential space was targeted as an evaluation object. 6 living rooms and 9 elements contained in each living room were evaluated in terms of luxuriousness. Through independent samples t-test, we could examine that there were statistically significant...
In recent years, hand drawn sketch based 3D model retrieval method has become a popular research area due to the rapid growth of available 3D models on the Internet. However, most existing sketch based 3D model retrieval methods only consider using low-level visual features that cannot capture users'search intention. In this paper, we propose a novel sketch-based 3D model retrieval approach by using...
Virtual application and its capabilities are increasing while they are getting easier to use day by day. VR is a term that applies to computer simulated environment that simulate physical presence in place in the real world. This paper describes the virtual system in the field of science and technology that explore the different virtual application and there integration techniques. The idea is to...
During the teleoperation of construction machines, it is highly needed to visualize the machine body itself. This is because the operator needs to perform a visual confirmation of the construction machine. In addition, information of crawler parts' shoe slip is indispensable. Therefore, not only the surrounding environment but also the vehicle body are needed to be visualized. This paper proposes...
In this paper, we address the 3D eye gaze estimation problem using a low-cost, simple-setup, and non-intrusive consumer depth sensor (Kinect sensor). We present an effective and accurate method based on 3D eye model to estimate the point of gaze of a subject with the tolerance of free head movement. To determine the parameters involved in the proposed eye model, we propose i) an improved convolution-based...
In this paper, we propose a saliency detection model for RGB-D images based on the contrasting features of color and depth within a Bayesian framework. The depth feature map is extracted based on superpixel contrast computation with spatial priors. We model the depth saliency map by approximating the density of depth-based contrast features using a Gaussian distribution. Similar to the depth saliency...
Visual texture modeling based on multidimensional mathematical models is the prerequisite for both robust material recognition as well as for image restoration, compression or numerous physically correct virtual reality applications. A novel multispectral visual texture modeling method based on a descriptive, unusually complex, three-dimensional, spatial Gaussian mixture model is presented. Texture...
This poster presents the problem of 3D contact measurements from two co-registered volumetric images (z-stacks). The 3D contact measurement consists of (a) segmenting an object of interest in each z-stack, (b) computing the relative spatial positions of the detected objects to detect contacts, (c) validating the accuracy of segmentation, and (d) visually verifying correct contact detection. The 3D...

This paper proposes a novel method for protein function recognition using deep learning. Recently, deep convolutional neural networks (DCNNs) demonstrated high performances in many areas of pattern recognition. Protein function is often associated with its tertiary structure denoting the active domain of a protein. This investigation develops a novel DCNN for protein functionality recognition based...
Analyze the characteristic of three-dimensional scene visualization and regulation of scene change in flight simulation system, which is the basis of implementation of terrain reconstruction. Give the related mathematics model of terrain visualization. In order to resolve the problem that three-dimensional scene could not be reconstructed fast because of large-scale terrain data, present a procedure...
Concepts of 3-dimensional (3D) Geometry are challenging to grasp for school students. The skill of manipulating 3D objects and interpreting their structure and properties are difficult. Traditionally to teach topics that have three dimensions, 3D artifacts have been used. However the opportunity of the learner to interact during the construction and manipulation of 3D objects is desirable. In this...
We use the high resolution Weather Research and Forecasting (WRF) model to predict the characteristics of an intense cyclone, Chapala, which formed over the Arabian Sea in October/November 2015. The implemented model consists of two-way interactive nested domains of 9 and 3km. The prediction experiment of the cyclone started on 1200UTC of 26 October 2015 to forecast its landfall and its intensity...
In this paper, we present a GPU accelerated volume carving technique, that aims to estimate and render on the fly all visible parts of a visual hull from a novel viewpoint. We have carefully adapted our algorithm implementation to the recent GPU-programming tools: CUDA (NVIDIA Compute Unified Device Architecture) and Modern OpenGL GLSL. We were able to carve out the desired part of the 3D volume,...
