How Tactor Size and Density of Normal Indentation Tactile Displays Affects Grating Discrimination Tasks
Found in: IEEE Transactions on Haptics
By Nadia Garcia-Hernandez,Federica Bertolotto,Ferdinando Cannella,Nikolaos G. Tsagarakis,Darwin G. Caldwell
Issue Date:July 2014
pp. 356-366
Tactile fingertip devices of vertically moving tactors have two important design parameters that significantly affect physical feedback and human tactile perception: tactor size and tactor density. However, there are a limited number of research studies th...
A High Performance Tactile Feedback Display and Its Integration in Teleoperation
Found in: IEEE Transactions on Haptics
By Ioannis Sarakoglou,Nadia Garcia-Hernandez,Nikos G. Tsagarakis,Darwin G. Caldwell
Issue Date:July 2012
pp. 252-263
This paper presents the development of a compact tactile display and its integration in teleoperation. The system's operation is based on the display of surface shape to an area of the fingertip through a 4 \times 4 array of tactors moving perpendicularly ...
Haptic-Enabled Multimodal Interface for the Planning of Hip Arthroplasty
Found in: IEEE Multimedia
By Nikolaos G. Tsagarakis, John O. Gray, Darwin G. Caldwell, Cinzia Zannoni, Marco Petrone, Debora Testi, Marco Viceconti
Issue Date:July 2006
pp. 40-48
The authors apply a multimodal interface for preoperative planning of hip arthroplasty with a user interface that integrates immersive stereo displays and haptic modalities. This article overviews this multimodal application framework and discusses the ben...
Human Tactile Ability to Discriminate Variations in Small Ridge Patterns thorugh a Portable-Wearable Tactile Display
Found in: International Conference on Advances in Computer-Human Interaction
By Nadia Garcia-Hernandez, Nikos G. Tsagarakis, Darwin G. Caldwell
Issue Date:February 2010
pp. 38-43
This work presents a quantitative evaluation of subjects’ tactile ability to discriminate small virtual ridge patterns through a portable–wearable tactile device. The virtual patterns have been recreated by controlling the vertically moving pins of the dev...
Integrating Haptics with Augmented Reality in a Femoral Palpation and Needle Insertion Training Simulation
Found in: IEEE Transactions on Haptics
By Timothy R. Coles,Nigel W. John,Derek A. Gould,Darwin G. Caldwell
Issue Date:July 2011
pp. 199-209
This paper presents a virtual environment for training femoral palpation and needle insertion, the opening steps of many interventional radiology procedures. A novel augmented reality simulation called PalpSim has been developed that allows the trainees to...
Anisotropic Contour Completion for Cell Microinjection Targeting
Found in: Pattern Recognition, International Conference on
By Gabriele Becattini, Leonardo S. Mattos, Darwin G. Caldwell
Issue Date:August 2010
pp. 2262-2265
This paper shows a novel application of the diffusion tensor for anisotropic image processing. The designed system aims at spotting and localizing injection points on a population of adherent cells lying on a Petri’s dish. The overall procedure is describe...
A Mixed-Reality Training System for Teleoperated Biomanipulations
Found in: International Conference on Advances in Computer-Human Interaction
By Leonardo Mattos, Darwin G. Caldwell
Issue Date:February 2010
pp. 169-174
This paper presents a mixed-reality system for the training of operators (biologogist/neuroscientists) on fully teleoperated biomanipulations. These tasks are traditionally performed via direct manual control of the biomanipulation equipment while looking ...
