    • Learning Meaningful Representations of Surgical Motion Without Annotations 

      DiPietro, Robert (2019)
      Superior technical skill in the operating room is associated with better patient outcomes [3,18], and at the core of surgical education is the belief that technical skill is improved through deliberate practice and appropriate ...
    • Mobile in-situ visualization 

      Tehrani, Mahdi Abbaspour (2017-09-01)
      In this work we present a new distributed technique to geometrically calibrate multiple projectors on a fiducial free arbitrary surface using multiple casually aligned cameras where every point of the surface is seen by ...
    • Modeling Self-Organization in Human Crowds 

      Wirth, Trenton D. (2020)
      Developing an understanding of human crowd movement is critical for optimizing crowd safety, both on the streets and in buildings. It is well understood from the study of animal collective motion that individuals are ...
    • A New Object Representation For Graphics 

      Thall, Andrew (1999)
      M-reps are a multiscale approach to the modeling and rendering of 30 solid geometry. Traditional geometric models, whether b-reps or CSG, are represented at infinitesimal spatial scale and then require simplification ...
    • A Nonlinear Motion Cueing Algorithm With a Human Perception Model 

      Telban, Robert (2001)
      The objective of a motion system, when used in conjunction with a visual system, is to stimulate the pilot so that he can perceive the required motion cues necessary to fly the simulator within the same performance and ...
    • Physical Modeling for Interaction in Real-Time Simulation 

      Lisle, Curtis (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 

      Daher, Salam (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 

      Kaya, Iihan (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 

      Mark, William R. (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 

      Barbic, Jernej (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 

      Joyce, Richard (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 

      Rivaz, Hassan (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 

      Peck, Tabitha (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 

      Schorr, Samuel (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 

      Franceschini, Robert (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 

      Raskar, Ramesh (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 

      Meenakshisundaram, Gopi (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 ...
