Haptic Processing of Facial Expressions of Emotion in 2D Raised-Line Drawings
Found in: IEEE Transactions on Haptics
By Susan J. Lederman, Roberta L. Klatzky, E. Rennert-May, J.H. Lee, K. Ng, Cheryl Hamilton
Issue Date:January 2008
pp. 27-38
Participants haptically (vs. visually) classified universal facial expressions of emotion (FEEs) depicted in simple 2D raised-line displays. Experiments 1 and 2 established that haptic classification was well above chance; face-inversion effects further in...
 
Haptic Classification of Facial Identity in 2D Displays: Configural versus Feature-Based Processing
Found in: IEEE Transactions on Haptics
By Tara A. McGregor, Roberta L. Klatzky, Cheryl Hamilton, Susan J. Lederman
Issue Date:January 2010
pp. 48-55
Participants learned through feedback to haptically classify the identity of upright versus inverted versus scrambled faces depicted in simple 2D raised-line displays. We investigated whether identity classification would make use of a configural face repr...
 
Please Touch: Object Properties that Invite Touch
Found in: IEEE Transactions on Haptics
By Roberta L. Klatzky,Joann Peck
Issue Date:January 2012
pp. 139-147
Touch has received increasing interest in marketing, given research indicating that contact with products influences evaluation and the tendency to purchase. However, little is known from the marketing or psychophysical literature about visible attributes ...
 
Combination and Integration in the Perception of Visual-Haptic Compliance Information
Found in: IEEE Transactions on Haptics
By Martin Kuschel, Massimiliano Di Luca, Martin Buss, Roberta L. Klatzky
Issue Date:October 2010
pp. 234-244
The compliance of a material can be conveyed through mechanical interactions in a virtual environment and perceived through both visual and haptic cues. We investigated this basic aspect of perception. In two experiments, subjects performed compliance disc...
 
Good vibrations: Asymmetric vibrations for directional haptic cues
Found in: World Haptics Conference
By Hanns W. Tappeiner, Roberta L. Klatzky, Bert Unger, Ralph Hollis
Issue Date:March 2009
pp. 285-289
In this paper we present a new concept for haptic guidance in multiple dimensions, in the form of asymmetric vibrations. We show that by adding asymmetry, vibrations from a single source can, like continuous forces, provide effective, high-resolution direc...
 
Psychophysical Evaluation of In-Situ Ultrasound Visualization
Found in: IEEE Transactions on Visualization and Computer Graphics
By Bing Wu, Roberta L. Klatzky, Damion Shelton, George D. Stetten
Issue Date:November 2005
pp. 684-693
We present a novel psychophysical method for evaluating ultrasonography based on Real-Time Tomographic Reflection (RTTR), in comparison to Conventional Ultrasound (CUS). The method measures the user's perception of the location of an ultrasound-imaged targ...
 
How Well Can We Encode Spatial Layout from Sparse Kinesthetic Contact?
Found in: Haptic Interfaces for Virtual Environment and Teleoperator Systems, International Symposium on
By Roberta L. Klatzky, Susan J. Lederman
Issue Date:March 2003
pp. 179
We investigated people?s ability to report the shape and scale of a spatial layout after sparse contact, without vision. We propose that the initial representation of sparsely contacted layout is kinesthetic. From this can be computed a configural represen...
 
Relative Performance Using Haptic and/or Touch-Produced Auditory Cues in a Remote Absolute Texture Identification Task
Found in: Haptic Interfaces for Virtual Environment and Teleoperator Systems, International Symposium on
By S. J. Lederman, Andrea Martin, Christine Tong, Roberta L. Klatzky
Issue Date:March 2003
pp. 151
The current study assessed the relative effectiveness with which unimodal tactile, unimodal touch-produced auditory, and bimodal tactile + auditory cues contribute to the performance of an absolute texture identification task via remote touch. The study co...
 
Search Efficiency for Tactile Features Rendered by Surface Haptic Displays
Found in: IEEE Transactions on Haptics
By John Ware,Elizabeth Cha,Michael A. Peshkin,J. Edward Colgate,Roberta L. Klatzky
Issue Date:May 2014
pp. 1
Haptic interfaces controlled by a single fingertip or hand-held probe tend to display surface features individually, requiring serial search for multiple features. Novel surface haptic devices, however, have the potential to provide displays to multiple fi...
 
Evaluation of spatial displays for navigation without sight
Found in: ACM Transactions on Applied Perception (TAP)
By Ethan L. Smith, Jack M. Loomis, James R. Marston, Reginald G. Golledge, Roberta L. Klatzky
Issue Date:April 2006
pp. 110-124
We report on two route guidance tasks using a highly accurate GPS receiver. Eight participants who were visually impaired or blind traveled two routes, one on a city sidewalk, and one in a city park. We tested and compared two types of spatial output devic...
     
Using psychophysical techniques to design and evaluate multimodal interfaces: psychophysics and interface design
Found in: Proceedings of the 14th ACM international conference on Multimodal interaction (ICMI '12)
By Roberta L. Klatzky
Issue Date:October 2012
pp. 383-384
"Psychophysics" is a an approach to evaluating human perception and action capabilities that emphasizes control over the stimulus environment. Virtual environments provide an ideal setting for psychophysical research, as they facilitate not only stimulus c...
     
The perceived roughness of resistive virtual textures: II. effects of varying viscosity with a force-feedback device
Found in: ACM Transactions on Applied Perception (TAP)
By Cheryl Hamilton, Christine Tong, Roberta L. Klatzky, Susan J. Lederman
Issue Date:January 2006
pp. 15-30
Klatzky and Lederman [2006] have shown that tangential resistive forces may be used to convey roughness in virtual textures using the WingMan force-feedback mouse. Modeling our experiment after this study, we directly examined the effect of viscous resista...
     
The perceived roughness of resistive virtual textures: I. rendering by a force-feedback mouse
Found in: ACM Transactions on Applied Perception (TAP)
By Roberta L. Klatzky, Susan J. Lederman
Issue Date:January 2006
pp. 1-14
In previous work, we demonstrated that people reliably perceive variations in surface roughness when textured surfaces are explored with a rigid link between the surface and the skin [e.g., Klatzky and Lederman 1999; Klatzky et al. 2003]. Parallel experime...
