Exploratory Movement Parameters Vary with Stimulus Stiffness

چکیده
This study investigates the influence of stimulus properties on explorative movement parameters in active touch. Using a PHANToM force-feedback device we generated virtual stimuli with different stiffness values. Participants freely explored pair-wise presented stimuli and were asked to select the softer one. Afterwards we analyzed their explorative movements considering the parameters velocity, pressure and the indentation depth. We found a systematic influence of stimulus stiffness on pressure/indentation depth and velocity. We conclude that observers adapted the movement parameters depending on stiffness variations.

Methodological Aspects of Cognitive Rehabilitation with Eye Movement Desensitization and Reprocessing (EMDR)
A variety of nervous system components such as medulla, pons, midbrain, cerebellum, basal ganglia, parietal, frontal and occipital lobes have role in Eye Movement Desensitization and Reprocessing (EMDR) processes. The eye movement is done simultaneously for attracting client's attention to an external stimulus while concentrating on a certain internal subject. Eye movement guided by therapist i...
متن کاملStress Analysis of Two-directional FGM Moderately Thick Constrained Circular Plates with Non-uniform Load and Substrate Stiffness Distributions
In the present paper, bending and stress analyses of two-directional functionally graded (FG) circular plates resting on non-uniform two-parameter foundations (Winkler-Pasternak foundations) are investigated using a first-order shear-deformation theory. To enhance the accuracy of the results, the transverse stress components are derived based on the three dimensional theory of elasticity. The s...
متن کاملPerception of Delay in Haptic Telepresence Systems
Time delay is recognized as an important issue in haptic telepresence systems as it is inherent to long-distance data transmission. What factors influence haptic delay perception in a time-delayed environment are, however, largely unknown. In this article, we examine the impact of manual movement frequency and amplitude in a sinusoidal exploratory movement as well as the stiffness of the haptic...
متن کاملLocalized cell stiffness measurement using axial movement of an optically trapped microparticle.
A simple optical tweezers design is proposed to manipulate particles in the axial direction and estimate particle position with nanometer sensitivity. Balb3T3 cell is probed using two different-sized particles, and the localized cell stiffness is evaluated using Hertz model. A series of experiments are performed to obtain the necessary parameters for the cell stiffness computation: particle dis...
متن کاملPostural constraints on movement variability.
Movements are inherently variable. When we move to a particular point in space, a cloud of final limb positions is observed around the target. Previously we noted that patterns of variability at the end of movement to a circular target were not circular, but instead reflected patterns of limb stiffness-in directions where limb stiffness was high, variability in end position was low, and vice ve...
