    • Kane's Equations for Haptic Display of Multibody Systems 

      Gillespie, R. Brent (Haptics-e, The electronic journal of haptics research, 2003-08-18)
      The design of a general-purpose multibody simulator that runs in real-time and features haptic display is presented. The repertoire of this simulator includes systems subject to holonomic con-straints, nonholonomic ...
    • Perceiving Surface Roughness via a Rigid Probe: Effects of Exploration Speed and Mode of Touch 

      Lederman, S.J.; Klatzky, R.L.; Hamilton, C.L.; Ramsay, G.I. (Haptics-e, 1999-10-07)
      Two experiments investigated the psychophysical consequences for roughness perception of altering the speed of motion with which textured surfaces are explored using a rigid probe. Two speed ranges were used: a 10-fold ...
    • Personal Responsibility in the Age of User-Controlled Neuroprosthetics 

      Brown, Timothy || Moore, Patrick || Herron, Jeffrey || Thompson, Margaret || Bonaci, Tamara || Goering, Sara || Chizeck, Howard Jay
      Deep-brain stimulation systems are an accepted and clinically effective form of neuroprosthetic treatment for a variety of common and debilitating neurological movement disorders
    • Short Time Fourier Analysis of the Electromyogram 

      Hannaford, Blake || Lehman, Steven
      We applied short-time Fourier analysis to surface electromyograms (EMG) recorded during rapid movements, and during isometric contractions at constant forces. We selected a portion of the data to be transformed by multiplying ...
    • Synchronization analysis of the uterine magnetic activity during contractions 

      Ramon, Ceon; Preissl, Hubert; Murphy, Pam; Wilson, James D.; Lowery, Curtis; Eswaran, Hari (2005)
      Background: Our objective was to quantify and compare the extent of synchronization of the spatial-temporal myometrial activity over the human uterus before and during a contraction using transabdominal magnetomyographic (MMG) ...
    • A Unified Treatment of Elastostatic Contact Simulation for Real Time Haptics 

      James, Doug; Pai, Dinesh (Haptics-e, The electronic journal of haptics research, 2001-09-27)
      We describe real-time, physically-based simulation algorithms for haptic interaction with elastic objects. Simulation of contact with elastic objects has been a challenge, due to the complexity of physically accurate ...
    • UW Sinus Surgery Cadaver/Live Dataset (UW-Sinus-Surgery-C/L) 

      Lin, Shan; Qin, Fangbo; Bly, Randall A.; Moe, Kris S.; Hannaford, Blake (2020)
      This dataset was developed at the University of Washington's BioRobotics Lab (http://brl.ee.washington.edu). It has endoscopic sinus surgery images with manual annotations for surgical instrument segmentation task. The ...
    • Virtual Training for a Manual Assembly Task 

      Adams, R.J.; Klowden, D.; Hannaford, Blake (Haptics-e, The electronic journal of haptics research, 2001-10-17)
      This paper describes an experiment, conducted to investigate the benfits of force feedback for virtual reality training of a real task. Three groups of subjects received different levels of training before completing a ...
    • Voxel-Based 6-DOF Haptic Rendering Improvements 

      McNeely, W.A.; Puterbaugh, K.D.; Troy, J.J. (Haptics-e, The electronic journal of haptics research, 2006-01-19)
      An approach is presented for realizing an order-of-magnitude improvement in spatial accuracy for voxel-based 6-DOF haptics. It trades constant-time performance for greater spatial accuracy. This helps to make 6-DOF haptics ...
