    Haptically perceived space was investigated in eight experimental conditions. The task of the subjects was to make an extensive field of bars parallel to another at a variety of fixed positions, either on a horizontal plane or on the midsagittal plane, and either with their right hand or with their left hand. Settings were correlated with the orientations of the hand when placed at the same locati... View full abstract»

    Interest in the use of tactile information displays has grown rapidly in recent years. However, relatively little research has been conducted to explore any cognitive and/or attentional limitations that may be inherent when using the body as a receptor surface for the transmission of information. In the present study, participants attempted to detect changes to tactile patterns presented sequentia... View full abstract»

    In this paper we report on results of a psychophysical experiment in which the optic illusion of Ouchi is reproduced in the tactile domain. In the vision field, when eyes scan over a texture grid, consisting of two rectangular checkerboard patterns oriented in orthogonal directions, the inset pattern appears to move relatively to the surrounding grid. A simplified 3D version of this pattern was re... View full abstract»

    The addition of force feedback to virtual environments and teleoperators provides many benefits to the user. However, the mechanisms by which force feedback improves performance remain unknown. We present an experiment demonstrating that force feedback can provide a physical constraint to an operator's motion, passively restraining the hand and reducing error even before the operator can voluntari...

    A layered protocols interaction model to describe haptic communication between two persons over a network is presented. This approach allows to consider all aspects of the haptic communication process: the intention to do an action, limitations of the human body, the communication device, and the network. The goal of the model is threefold, firstly it is a tool to identify problems and opportuniti... View full abstract»

    The increasing complexity and pervasiveness of handheld devices is demanding the development of interaction techniques explicitly tailored for mobile scenarios. This paper examines one such technique: the use of device orientation to navigate through one dimensional lists or menus. We describe a novel input mapping, directly relating list position to device orientation, and two studies quantifying... View full abstract»

    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 interactions for training and museum displays, it is only a matter of time that haptic digital media become available on the Internet. For example,...

    A wearable haptic interface has been developed to impart vibrotactile information to its user with the goal of improving situation awareness. The effectiveness of the haptic interface has been evaluated in three experiments aboard the NASA KC-135A reduced gravity aircraft. During the third flight, subjects identified the locations of tactors embedded in the haptic display in a microgravity environ... View full abstract»

    People rely on tactile edge localization to ascertain the location and structure of edges. When pressure is applied to the skin, skin mechanoreceptors convert compressive stress/strain into neural signals. Many attempts to model this conversion neglect intermediate ridges, on the inside of the stiff epidermis. The receptors associated with detecting compressive and shear stresses reside at the tip...

    Although many robots and haptic interfaces are of the impedance type, admittance-type devices offer distinct advantages, such as high damping and stiffness display, particularly in applications requiring precise motion control. This study seeks to quantify human force control limitations in admittance control systems, where robot velocity is controlled to be proportional to the force applied by a ... View full abstract»

    The processing of spatio-temporal vibrotactile patterns by the torso was examined in two experiments. The first investigated the spatial acuity as function of location on the torso. A uniform acuity between 2 and 3 cm was found, except on the body midline where acuity was about 1 cm. This favorable effect was hypothesized to be caused by specific processing characteristics of the central nervous s... View full abstract»

    In a series of three experiments, participants were asked to match the sizes of spheres presented in the haptic and visual modalities. Stimuli were either real or virtual. Real spheres were sets of ball bearings of various sizes that could be both viewed and touched. Virtual spheres were presented using a Phantom for the haptic presentations or a 4D screen for the visual presentations. Comparing t... View full abstract»

    A tactile display for use in navigation has been designed and evaluated. In these experiments, the ability of subjects to identify patterns of vibrotactile stimulation was tested using tactile displays mounted on the arm and torso. The performance of two types of motors (pancake and cylindrical) was also compared at both sites. The results indicated that identification of the vibrotactile patterns... View full abstract»

    This paper investigates spatiotemporal tactile perceptive characteristics and biomechanical properties of human skin and considers their implications for the design of tactile displays. Three separate experiments were conducted. First, we measured vibrotactile thresholds as a function of frequency of vibration, using a cylindrical contactor of 0.7 mm diameter. The results of our experiment showed ... View full abstract»

    In this research, we propose a method for a quantitative evaluation of the variation and the similarity of manipulation among the subjects. The evaluation is performed by observing the contact state transition on the palm surface and by using continuous DP matching. Using this method, the individual variation and the level of familiarization of manipulative skills can be evaluated. The evaluation ... View full abstract»

    Active subjects freely explored virtual three-dimensional geometric shapes using a phantom force-feedback device. Each active subject's movements were used to guide a passive subject over the same stimuli. In experiment 1 the active subject's movements were recorded and "played back" to the passive counterpart at a later time - a delayed yoking. Two phantoms were used in experiment 2 so that as th...

    This paper addresses the discriminability of virtual haptic textures rendered with different update rates. Two psychophysical experiments were conducted. In the first experiment, we examined the pairwise discriminability of textured surfaces rendered with different update rates. In the second experiment, we measured the discrimination threshold of update rate for a reference textured surface rende... View full abstract»

    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 (Ml) and measured TMS-evoked forces in a multi-fingered grasp. This short report aims at presenting the experimental setup and some preliminary results. The analysis of the data fro... View full abstract»

    We perform experiments to investigate how humans acquire an internal representation of virtual objects through the execution of reaching movements across the object surface. Subjects were instructed to make reaching movements between points lying on the boundary of a planar virtual surface of varying stiffness. Results suggest two types of internal representation: force perturbations and object bo... View full abstract»
