Passive, active and intra-active (self) touch.
A series of experiments are described in which magnitude estimates of the perceived size of steel balls were made when the balls were actively rolled between the fingertip and several other body sites (thumb, thenar eminence, forearm). This movement, called scripting, involves actively moving an object by a touching surface over another surface of the body which is passively being touched. We d...
متن کاملPassive and Active Touch – Preliminary Report
The TOUCH-HapSys collaborative project investigates the psychophysical basis of human tactual perception in order to improve the efficiency and reliability of haptic displays. The present deliverable reports on the progress made in investigations on the basic tactual modes of active and passive touch. In psychophysical experiments MPI-T started to examine the principles of cue integration for a...
متن کاملAn fMRI study on cortical responses during active self-touch and passive touch from others
Active, self-touch and the passive touch from an external source engage comparable afferent mechanoreceptors on the touched skin site. However, touch directed to glabrous skin compared to hairy skin will activate different types of afferent mechanoreceptors. Despite perceptual similarities between touch to different body sites, it is likely that the touch information is processed differently. I...
متن کاملThe relative timing of active and passive touch.
Tactile stimulation usually occurs as a combination of an active movement (reaching out to touch a surface) and a sensation (actually feeling the surface against the skin). The brain has information about the active component (the motor command) before it occurs because of efference copy, while the passive component must be transduced before it can be processed. Since the active and passive tac...
متن کاملPerception of simulated local shapes using active and passive touch.
This study reexamined the perceptual equivalence of active and passive touch using a computer-controlled force-feedback device. Nine subjects explored a 6 x 10-cm workspace, with the index finger resting on a mobile flat plate, and experienced simulated Gaussian ridges and troughs (width, 15 mm; amplitude, 0.5 to 4.5 mm). The device simulated shapes by modulating either lateral resistance with ...
