Switching Between Objects Improves Precision in Haptic Perception of Softness

Abstract: Haptic perception involves active exploration usually consisting of repeated stereotypical movements. The choice of such exploratory movements and their parameters are tuned to achieve high perceptual precision. Information obtained from repeated exploratory movements (e.g. repeated indentations of an object to perceive its softness) is integrated but improvement of discrimination performance is limited by memory if the two objects are explored one after the other in order to compare them. In natural haptic ex… Show more

B) Normalized observed discrimination performance in instructed explorations (study 2 [22]) as a function of normalized predicted performance. Here brighter colors indicate more number of switches.…”

“…There were four references and for each reference there were two comparisons one softer and the other harder. The compliances of the stimuli were the following: reference r 1 : 0.14 mm/N, comparisons c 1 1 : 0.12 mm/N, c We further took the behavioral data from [22] (later referred to as study 2). Here 11 participants completed a 2AFC task.…”
