“…Drewing and colleagues (Drewing & Ernst, 2006;Drewing & Kaim, 2009;Kaim & Drewing, 2010) proposed that a maximum likelihood estimation combination of cues explains haptic perception of shape properties. Conceivably, some similar combination of influences affected IFD judgments under the conditions tested in the present experiments.…”

“…Drewing and colleagues (Drewing & Ernst, 2006;Drewing & Kaim, 2009;Drewing et al, 2008;Kaim & Drewing, 2010) pointed out that some haptic spatial perceptual effects (i.e., surface curvature judgments) apparently depend on an amalgam of information from changing finger position and force change, both available as the finger moves across a curved surface. Robles-de-la-Torre and Hayward (2001) demonstrated that when force and geometry (essentially, finger position) conflict, force relationships take priority in categorizing curved versus flat surfaces.…”

“…Drewing and colleagues (Drewing & Ernst, 2006;Drewing & Kaim, 2009;Drewing, Wiecki, & Ernst, 2008;Kaim & Drewing, 2010) have documented the utility of hand-arm position information along a curved path as a basis for haptic discrimination of (typically, Gaussian) curves. A number of other studies examining haptic curvature perception (e.g., Kappers, Koenderink, & Lichtenegger, 1994) have implicated finger-hand-arm position information as a basis for discrimination of curvature differences.…”

Haptic distal spatial perception mediated by strings: Size at a distance and egocentric localization based on ellipse geometry

Participants explored ellipse perimeters defined by fixed-length strings, held taut by their moving finger, with ends attached to two fixed hooks (foci). Participants haptically judged ellipse interfocal distance (IFD; in effect, exocentric separation, or size at a distance) or location of ellipse major axes (i.e., egocentric localization relative to the moving finger). In Experiment 1A, perceivers made reliable and accurate multialternative forced choice IFD judgments. Experiment 1B showed similar reliability for direct estimations but showed greater scaling error. In Experiment 2, perceivers reliably localized ellipse major axes. Both experiments derived from a priori geometrical analysis, consistent with the Gibsonian perceptual research program and previous string-mediated haptic distal spatial studies. Results are discussed with respect to haptic perception as a telemodality and to dynamic touch.

“…Already mentioned was Drewing and Ernst's (2006) research, which demonstrated that the vertical force that a perceiver exerts in exploratory rubbing of a surface differentially weights cues in haptic shape perception. Kaim and Drewing (2010) went on to demonstrate that an exploration-based integration model accounted for results that could not be accounted for by cognitive integration of individual cues using a maximum likelihood estimation model (e.g., Ernst & Banks, 2002). …”

“…In other words, we deny that cues are combined. Drewing and colleagues (Drewing & Ernst, 2006;Kaim & Drewing, 2010) have made an analogous argument for haptic exploration, asserting that the modulation of exploratory force functionally weights the cues of position and force in haptic shape perception.…”

Information space is action space: perceiving the partial lengths of rods rotated on an axle

In a single experiment, perceivers held unseen rods at some position along their lengths and reported the two partial lengths-to the left and to the right of the hand. Wielding was mechanically limited to a vertical plane. Previous research suggested that the information exploited for this task is captured in a space created from the moment of inertia and gravitational torque. The experiment reported here attempted to replicate the relevance of that space and to ask how exploration might access it. Perceivers were given feedback on accuracy on Blocks 2 and 3 of a fourblock experiment, and their performance and position in information space were monitored. Exploratory movements were recorded. Judgments were shown to depend on inertial and gravitational torques, as expected. Analysis of exploratory movements suggested that occupying a locus in information space is equivalent to exploring at some angular acceleration. The apparent weighting of cues (gravitational and inertial torque), which might be interpreted as a cognitive process, was instead interpreted as a consequence of manner of exploration.
