“…Figure 3 illustrates the approach that we (Henriques and Soechting 2003) used to address these questions. Similar procedures were used by Hogan and colleagues (Fasse et al 2000;Hogan et al 1990). To determine one of the geometric parameters, subjects moved the manipulandum in the horizontal plane as often as they liked along a haptic boundary that was about 15 cm long.…”

“…More precisely, by combining results from 2 orientations, they predicted that an ellipse with an aspect ratio of 1.29 and a major axis oriented 17°to the x-axis should be sensed as circular. This size distortion depends on the location in the workspace, increasing with distance from the shoulder (Hogan et al 1990). We found a slightly smaller effect than that reported by Fasse et al (2000); on average subjects reported an ellipse with an aspect ratio of 1.07 (i.e., a wide ellipse) to be circular, and mistook a circle for a slightly tall ellipse (Henriques and Soechting 2003).…”

“…In this scenario, deviations from a planned trajectory along a constraint would generate variations in the normal component of the force and these variations could be used to identify the curvature of the contour. More generally, because subjects are able to discriminate variations in compliance (Hogan et al 1990;Hunter 1989, 1990), surface compliance could introduce a bias in the haptic perception of curvature. To investigate this possibility, we varied the stiffness of the contour as subjects determined whether it curved in or out (Song et al 2004).…”

“…Slowly adapting type II (SAII) afferents also responded to these stimuli, but provided much coarser resolution. Hogan and colleagues (Fasse et al 2000;Hogan et al 1990) developed a different experimental paradigm that permits the study of haptic sensing on a larger spatial scale. In their studies, subjects grasped the handle of a robotically controlled manipulandum and explored the contours of virtual objects with movements that primarily involved the proximal arm.…”

Henriques, Denise Y. P. and John F. Soechting. Approaches to the study of haptic sensing. J Neurophysiol 93: 3036 -3043, 2005; doi:10.1152/jn.00010.2005. This review surveys results from a new approach to the problem of haptic sensing, in which subjects use primarily proximal arm movements to explore the shapes of virtual objects. These shapes are generated using a robotically controlled manipulandum. We begin by summarizing distortions of simple geometric properties (such as the length and orientation of lines) in the haptic perception of space. We then consider the extent to which the sense of more complex shapes (such as quadrilaterals) can be explained by these geometric distortions, i.e., the extent to which the shape of a complex object is synthesized from simpler constituent elements, and some of the sensory cues that may be important in this process. Haptic and visual processing of shapes appear to lead to some similar illusions. However, we argue that the processing of haptic information differs fundamentally from visual processing in that the former requires the integration of information that evolves in time as well as in space.

“…Davidon and Cheng reported that subjects consistently overestimated the lengths of objects when using a radial movement rather than a lateral one, but disputed analogy with visual effects [17]. In any case, this type of effect invariably involves the performance of significant movement by the limbs, fingers or arms [13,42,3].…”

This paper surveys more than twenty types of tactile illusions and discusses several of their aspects. These aspects include the ease with which they can be demonstrated and whether they have clear visual analogs. The paper also shows how to construct equipment made of simple supplies able to deliver well controlled tactile signals in order to conveniently demonstrate four different tactile illusions.
