The state of the art VR/AR devices provide access to completely virtual environments or augment information on the existing world seen by the user. Wearable devices encumber the users, and sometimes even cut them off completely from the real world. Users interact with digital avatars instead of the real people themselves. Spatially augmented reality (SAR) instead focuses on illuminating physical spaces...
Many conventional approaches and treatments being insufficient to restrain the repercussion caused due to disorder and disability have initiated exploration on Virtual Reality for therapy. Experts having done research on efficacy of VR to overcome mental disorders specifically Post traumatic stress disorder (PTSD) and phobias demonstrate the scope of technology to overcome physical illness. Use of...
Content streaming is a mechanism used to distribute static geometry data to users of a virtual environment in real-time. Although most existing content streaming mechanisms have shown to meet their run-time performance requirements, they have an underlying constraint on the quality of 3D data that can be streamed. This restriction stems from the fact that most existing content streaming mechanisms...
In this paper we present a new distributed technique to geometrically calibrate multiple casually aligned projectors on a fiducial free arbitrary surface using multiple casually aligned cameras where every point of the surface is seen by at least one camera. Using a multi-step method that uses binary blob patterns, we estimate robustly the display's 3D surface geometry, the cameras' extrinsic parameters,...
Vibrant lighting of relief maps via high-resolution dynamic projected imagery can be a powerful tool for simulation, augmented reality, and visualization, enabling several scientific, educational and entertainment applications. This is usually achieved via multiple projectors lighting the relief map, which are then sensed by multiple cameras for geometric and color calibration. However, cumbersome...
Simultaneous modification and navigation of massive 3D models are difficult because repeated data edits affect the data layout and coherency on a secondary storage, which in turn affect the interactive out-of-core rendering performance. In this paper, we propose a novel approach for distributed data management for simultaneous interactive navigation and modification of massive 3D data using the readily...
We present a work in progress for a paradigm of wall-top displays for future offices, where instead of a small desktop, we treat the available walls as the desktop. Multiple projector-camera units, mounted on pan-tilt units (PTU), allow for the creation of the conglomeration of one or more high resolution displays, whose position, size, and aspect ratio can be changed by the user. This can be achieved...
In this paper, a stochastic Galerkin formulation for the variability analysis of power distribution network (PDN) structures within a SPICE environment is proposed. The key feature of this work is that the augmented PDN model arising due to the Galerkin projection is realized using a 3D topology of multiconductor transmission lines. Thereafter, a sophisticated delay extraction based modeling technique,...
