Perceptual Issues in Haptic Digital Watermarking
Found in: IEEE Multimedia
By Domenico Prattichizzo, Mauro Barni, Gloria Menegaz, Alessandro Formaglio, Hong Z. Tan, Seungmoon Choi
Issue Date:July 2007
pp. 84-91
The growing interest in haptic applications suggests that haptic digital media will soon become widely available, and the need will arise to protect digital haptic data from misuse. In this article, we present our study and findings on psychophysical exper...
 
Perceptibility of Haptic Digital Watermarking of Virtual Textures
Found in: World Haptics Conference
By Domenico Prattichizzo, Mauro Barni, Hong Z. Tan, Seungmoon Choi
Issue Date:March 2005
pp. 50-55
Digital watermarking refers to the process of embedding a digital code into an image, video, printed document or audio media. The code should not interfere with the normal use of the media but can be recovered later. With the growing interest in haptic int...
 
Effects of Transcranial Magnetic Stimulation of the Primary Motor Cortex on the Grip and Net Forces in the Tripod Grasp
Found in: World Haptics Conference
By Gabriel Baud-Bovy, Simone Rossi, Domenico Prattichizzo
Issue Date:March 2005
pp. 120-125
Transcranial magnetic stimulation (TMS) is a tool of choice to study the functionality of the corticospinal pathway in the intact human. In this study, we used TMS to stimulate the hand area of the primary motor cortex (M1) and measured TMS-evoked forces i...
 
Real-Time Soft-Finger Grasping of Physically Based Quasi-rigid Objects
Found in: World Haptics Conference
By Maurizio de Pascale, Gabriele Sarcuni, Domenico Prattichizzo
Issue Date:March 2005
pp. 545-546
This paper describes the implementation of a demo that will be shown at the conference site. The demo of
   
Dynamic Local Models for Stable Multi-Contact Haptic Interaction with Deformable Objects
Found in: Haptic Interfaces for Virtual Environment and Teleoperator Systems, International Symposium on
By Federico Barbagli, Kenneth Salisbury, Domenico Prattichizzo
Issue Date:March 2003
pp. 109
This paper describes a nw technique for allowing multiple users to haptically interact with a set of deformable slowly-simulated objects in a stable manner. Stability has been approached in the past by various researchers using passivity theory in order to...
 
Teleoperation of steerable flexible needles by combining kinesthetic and vibratory feedback
Found in: IEEE Transactions on Haptics
By Claudio Pacchierotti,Momen Abayazid,Sarthak Misra,Domenico Prattichizzo
Issue Date:February 2015
pp. 1
Needle insertion in soft-tissue is a minimally invasive surgical procedure that demands high accuracy. In this respect, robotic systems with autonomous control algorithms have been exploited as the main tool to achieve high accuracy and reliability. Howeve...
 
Human-robot formation control via visual and vibrotactile haptic feedback
Found in: IEEE Transactions on Haptics
By Stefano Scheggi,Fabio Morbidi,Domenico Prattichizzo
Issue Date:June 2014
pp. 1
In this paper we present a new visuo-haptic interaction mechanism for human-robot formation control. The formation setup consists of a human leader and multiple follower robots. The mobile robots are equipped only with RGB-D cameras, and they should mainta...
 
Effects of Kinesthetic and Cutaneous Stimulation During the Learning of a Viscous Force Field
Found in: IEEE Transactions on Haptics
By Giulio Rosati,Fabio Oscari,Claudio Pacchierotti,Domenico Prattichizzo
Issue Date:April 2014
pp. 251-263
Haptic stimulation can help humans learn perceptual motor skills, but the precise way in which it influences the learning process has not yet been clarified. This study investigates the role of the kinesthetic and cutaneous components of haptic feedback du...
 
Towards Wearability in Fingertip Haptics: A 3-DoF Wearable Device for Cutaneous Force Feedback
Found in: IEEE Transactions on Haptics
By Domenico Prattichizzo,Francesco Chinello,Claudio Pacchierotti,Monica Malvezzi
Issue Date:October 2013
pp. 506-516
Wearability will significantly increase the use of haptics in everyday life, as has already happened for audio and video technologies. The literature on wearable haptics is mainly focused on vibrotactile stimulation, and only recently, wearable devices con...

Vibrotactile haptic feedback for human-robot interaction in leader-follower tasks
Found in: Proceedings of the 5th International Conference on PErvasive Technologies Related to Assistive Environments (PETRA '12)
By Domenico Prattichizzo, Francesco Chinello, Stefano Scheggi
Issue Date:June 2012
pp. 1-4
In this paper we explore a vibrotactile feedback paradigm which allows the human to intuitively interact in human-robot applications. In particular we focus on a haptic bracelet which helps the human to move along trajectories that are feasible for the lea...
     
A framework for bounded-time collision detection in haptic interactions
Found in: Proceedings of the ACM symposium on Virtual reality software and technology (VRST '06)
By Domenico Prattichizzo, Maurizio de Pascale
Issue Date:November 2006
pp. 305-311
In this paper we present the V-GRAPH, a framework for bounded-time collision detection for point-like haptic interactions. This frame-work employs strategies similar to those used by the Lin-Canny and Dobkin-Kirkpatrick algorithms but, differently from the...
