Physical Modeling for Interaction in Real-Time Simulation
(1996)The goal of this project was to model objects in a simulated environment with a method which allows physically-correct behavior to be calculated in real-time. Our approach studied the interaction between differing object ... -
Physical-Virtual Patient Bed
(2017-08-28)Currently healthcare practitioners use patient simulators such as actors, mannequins, and computer based simulations for learning and training.I am exploring effects of co-locating sensory cues (i.e. visual and haptic) vs ... -
A Physics-based Modeling and Real-time Simulation of Biomechanical Diffusion Process through Optical Imaged Alveolar Tissues on Graphical Processing Units
(2009)Tissue engineering has broad applications fro1n creating the much needed engineered tissue and organ structures for regenerative medicine to providing in vitro testbeds for drug testing. In the later, application domain, ... -
Post-Rendering 3D Image Warping
(1997)A pair of rendered images and their Z-buffers contain almost all of the information necessary to re-render from nearby viewpoints. For the small changes in viewpoint that occur in a fraction of a second, this information ... -
Pre-computation Approach to Nonlinear Simulations of Deformable Objects
(2005)My research area involves building real-time interactive simulations of solid deformable objects. For example, liver tissue should defo1m realistically during a vi1tual surgery simulation. A virtual assembly simulation ... -
The Rapidly Reconfigurable Research Cockpit
(2015-09-01)The goal of the Rapidly Reconfigurable Research Cockpit (R3C) project is to create and evaluate a novel approach for aviation simulators. Our concept combines a virtual reality visual environment with the tactile feedback ... -
Real-Time Regularized Ultrasound Elastography
(2009)This paper introduces two real-time elastography techniques based on analytic minimization (AM) of regularized cost functions. The first method (1D AM) produces axial strain and integer lateral displacement, while the ... -
Redirected Free Exploration with Distractors
(2009)Users in virtual environments often find navigation n1ore difficult than in the real world, Our new locomotion interface, Redirected Free Exploration with Distractors (RFED), enables users to walk in larger-than-tracked ... -
Skin Deformation Feedback for Force Sensory Substitution in Teleoperation and Virtual Reality Training
(2017-08-28)For this work, we developed a wearable skin deformation device that is worn on the tip of the finger. The devices have two separate components, the first of which is a finger grounding interface that straps to the medial ... -
Software Tools for Solid Freeform Fabrication
(1998)A structured design methodology played a key role in the VLSI (Very Large Scale Integration) revolution. In this methodology, the design is abstracted at different levels (viz. system, function, logic, circuit, and layout) ... -
Spatially Augmented Reality
(1999)To create an effective illusion of virtual objects coexisting with the real world, see-through HMD-based Augmented Reality techniques supple1nent the user's view with images of virtual objects. We introduce here a new ... -
Surface Reconstruction based on Lower Dimensional Localized Delaunay Triangulation
(2000)We present a fast, memory efficient algorithm that generates a manifold triangular mesh S passing through a set of unorganized points Pc R3. Nothing is assumed about the geometry, topology or presence of boundaries in ... -
Using Advanced Driving Simulation and Vibrotactile Cues to Train Drivers to Interact with Next-Generation Autonomous Vehicles
(2021-07)There are six levels of vehicle automation, from Level 0 – no automation to Level 5, fully autonomous [1]. According to several projections, the majority of vehicles on the road will be at intermediate levels for the next ... -
Using immersive virtual reality to assess context-dependency of locomotor skill learning in people with Parkinson's disease
(2019)Parkinson’s disease (PD) is a progressive neurodegenerative disorder resulting from a loss of multisystem degenerations and neurotransmitter deficiencies such as dopaminergic and cholinergic degenerations [1]–[4]. The ... -
The Vacuum Buffer
(2001)Image-based rendering (IBR) techniques have the potential of alleviating some of the bottlenecks of traditional geometry-based rendering such as modeling difficulty and prohibitive cost of photorealism. One of the most ... -
A vision-based model of crowd navigation
(2019)Humans navigate crowds daily. This can range from quick interactions between pedestrians on the sidewalk to jostling through a busy train station. Research in fields diverse as computer graphics, physics, evacuation planning, ... -
Vision-Based Tracking with Dynamic Structure Light
(1998)The term virtual reality (VR) has been used in the popular press to describe systems that completely replace the user's view with computer graphics, a view of a synthetic world. Such systems allow building designers to ... -
Vortex Generated Rotor Wake Model for Real-Time Simulation
(1999)The University of Alabama Flight Dynamics Laboratory (UA FDL) has been simulating helicopters since 1981. The real-time, man-in-the-loop, simulator was developed locally and is continuously being upgraded. The hardware, ... -
A Wavelet-Based Approach to Dynamic Environments
(1998)This paper demonstrates a new approach for terrain representation: multiresolution surfaces based on wavelets and the process of multiresolution analysis. Because they are based on mathematical surfaces, multiresolution ...
