Sensory dominance in extended haptics: Applied stochastic method

Abstract

This study measured haptic extra accuracy, that is, judging one hit position in a hand-held object. Primarily, which factors are associated with the estimation of the contact position when an impact is made on the grasped implement. Data were collected from 20 participants and their extended haptic accuracy were analyzed using a discrete numerical state, as well as the stochastic evolutionary possibility. Analyzations proved that perceived accuracy influenced not only the stimulus magnitudes distinguished by the coefficient of restitution, but also the distributions of the encoded impressions by the rotational inertia. In particular, stochastic analysis confirmed that perceiving the location of the effect of grasped objects is more constrained by kinesthetic oriented property than by the cutaneous oriented gain in arbitrarily conflicted circumstances. The results from the analyzations suggest a broader hypothesis for further research into the effects of inertia tensor related to haptic spatial accuracy in a hand-held object.
