Abstract: | Perceived heaviness has been shown to be specific to an object’s rotational inertia (I ), its resistance to rotational acceleration.
According to the kinematic specification of dynamics (KSD) principle, we hypothesized that I is optically specified by rotational
kinematics. Using virtual depictions of wielded objects, we investigated whether the visually detected rotational kinematics
of wielded objects would influence perceived heaviness in a manner consistent with the inertial model of heaviness perception.
We scaled the virtual object’s movement so that it rotated more or less than its wielded counterpart, specifying lower and
higher I, respectively. Perceived heaviness was inversely related to the rotational scaling factor, consistent with a KSD
interpretation of the inertial model. |
