“…The processing of both stimuli are always combined during haptic sensation, regardless of whether those information are relevant in a particular task [40]. It has been found in a previous study on the human's haptic perception [41] that the small number of different sensory stimuli (single channel of tactile and single channel of proprioception) is preferred over a large number of the same type of sensory stimuli (multiple channels of tactile) alone.…”

Abstract-When humans are asked to palpate a soft tissue to locate a hard nodule, they regulate the stiffness, speed, and force of the finger during examination. If we understand the relationship between these behavioral variables and haptic information gain (transfer entropy) during manual probing, we can improve the efficacy of soft robotic probes for soft tissue palpation, such as in tumor localization in minimally invasive surgery. Here, we recorded the muscle co-contraction activity of the finger using EMG sensors to address the question as to whether joint stiffness control during manual palpation plays an important role in the haptic information gain. To address this question, we used a soft robotic probe with a controllable stiffness joint and a force sensor mounted at the base to represent the function of the tendon in a biological finger. Then, we trained a Markov chain using muscle co-contraction patterns of human subjects, and used it to control the stiffness of the soft robotic probe in the same soft tissue palpation task. The soft robotic experiments showed that haptic information gain about the depth of the hard nodule can be maximized by varying the internal stiffness of the soft probe.

“…They also showed that object recognition can be impaired when these exploratory movements are constrained (Lederman & Klatzky, 2004). Overvliet, Smeets, and Brenner (2008) found, in a search task in which items were 3-D shapes fixed in a grid, that search times were greatly reduced when the subjects were allowed to enclose the items, as compared with when they were allowed only to explore them with one finger, showing the effect of constraining exploratory strategies on haptic search times. Therefore, when human performance needs to be optimal, one should be cautious as to the constraints that are put on exploratory movements.…”

Shape is an important cue for recognizing an object by touch. Several features, such as edges, curvature, surface area, and aspect ratio, are associated with 3-D shape. To investigate the saliency of 3-D shape features, we developed a haptic search task. The target and distractor items consisted of shapes (cube, sphere, tetrahedron, cylinder, and ellipsoid) that differed in several of these features. Exploratory movements were left as unconstrained as possible. Our results show that this type of haptic search task can be performed very efficiently (25 msec/item) and that edges and vertices are the most salient features. Furthermore, very salient local features, such as edges, can also be perceived through enclosure, an exploratory procedure usually associated with global shape. Since the subjects had to answer as quickly as possible, this suggests that speed may be a factor in selecting the appropriate exploratory procedure.

“…While some studies have investigated tactile search on a behavioural level (e.g. Overvliet, Smeets and Brenner, 2008), the neural correlates of tactile search (when a tactile target needs to be identified amongst tactile distractor items) remain unexplored.…”
