Current research on skeleton tracking techniques focus on image processing in conjunction with a video camera constrained by bones and joint movement detection limits. The paper proposed 3D skeleton tracking technique using a depth camera known as a Kinect sensor with the ability to approximate human poses to be captured, reconstructed and displayed 3D skeleton in the virtual scene using OPENNI...

Head-related transfer functions (HRTFs) or impulse responses (HRIRs) capture the acoustic transmission path from an acoustic source to the ears. For ease of illustration we restrict our considerations to HRTFs H{L,R}(α0, R, ω) captured from sources in a plane, were (α0,R) denotes the position of the sound source. Note, the generalization of the proposed technique is straightforward. HRTFs are t...

Fast neutron sources are designed and experimentally tested, based on optimized conversion targets and linear accelerator as electron suppliers. Both gamma radiation and fast neutron emissions are studied, establishing the most effective characteristics of the targets in terms of material, spatial dimensions, relative position of target and source, incident electron energy. A numerical procedur...

On Wendelstein 7-X, electron density and electron temperature profiles are planned to be measured by Thomson scattering. The specific system employs fiber bundles for the scattered light which is detected by means of a five-channel polychromator system. The detection system is assembled and its components are characterized. A calibration technique employing a super-continuum light source is ass...

Interaction in Virtual Reality is accomplished through ”tracking devices”. These devices follow the position and orientation of real life objects, such as the user’s head and hands but also of other objects in order to provide a way to interact with virtual objects through objects in the real world. In this thesis we evaluate an optical tracking system for the Personal Space Station (PSS), a de...

Networked Collaborative Virtual Environments (NCVE) have been a hot topic of research for some time now. However, most of the existing NCVE systems restrict the communication between the participants to text messages or audio communication. The natural means of human communication are richer than this. Facial expressions, lip movements, body postures and gestures all play an important role in o...

background: this study was undertaken to establish the characterization of cultured oral mucosal epithelium and introducing them as an alternative source for reconstruction of ocular surface disease. methods: human oral epithelial cells were cultured on simple media (dmem/hf12) as control and co-cultured on mitomycin c-treated 3t3 feeder layer, on the amniotic membrane (am) without nitrocellulo...

In this paper we argue that the technology to create Virtual Environment (VE) is not yet to the point where we can ignore the effect on the user of the limits of the quality of the simulation. User cannot interact with the virtual world using the same techniques they use in the real world. We firmly believe there is a need to understand the limits and differences of the translation of real-worl...
