“…A visually induced effect on precision grip was not elicited despite their ability both to record precision grip with great accuracy and to induce compelling apparent up-down oscillation in their subjects. Our finding that subjects during experienced self-rotation and displacement did not sense the rod as exerting a centrifugal force on their hand is in accord with that of Bringoux and colleagues (Bringoux et al, 2012).…”

“…After 20 perturbed reaches adaptation was approximately 80% complete. It is possible that the effects observed by Dvorkin, et al, 2009 would be even larger if practice trials were not given. Bringoux and colleagues explored whether an object held in a pincer grip at a seated subject’s lap would show systematic anticipatory grip compensations for visually induced oscillatory vection in the absence of real motion (Bringoux et al, 2012, White et al, 2020). Such anticipatory adjustments of grip force rapidly develop during actual exposure to up-down oscillatory motion.…”

Looking at a virtual 3D environment with structural features rotating at 60°/s in a head-mounted display soon elicits an illusion of self-rotation and displacement in the opposite direction. We explored in 75 s long trials the effects of visually induced self-rotation on the head, torso, and horizontally extended right arm of standing subjects. The degree of body and limb movement was contingent on whether the arm was extended out freely or pointing at a briefly proprioceptively specified target position, but did not depend on whether the hand held a rod or not. Most subjects in the Free condition showed significant unintentional arm deviations, which averaged approximately 55° in the direction opposite the induced illusory self-motion, and were more than 150° in some cases. In contrast, on average, the deviations in the Pointing condition were a quarter of those in the Free condition. Deviations of head and torso positions also occurred in all conditions. Total arm and head deviations were the sum of deviations of the arm and head with respect to the torso plus deviations of the torso with respect to space. When given a pointing target, subjects were largely able to detect and correct for arm and head deviations with respect to the torso but not for the parts of arm and head deviation that were due to deviations of the torso with respect to space. In all conditions, the arm, head, and torso deviations occurred before subjects began to experience compelling self-rotation and displacement. This is contrasted with the compensations for expected but absent Coriolis forces that are made when stationary subjects make reaching movements to targets during exposure to structured moving visual scenes. These compensations do not occur until subjects experience self-rotation and spatial displacement. These results have implications for vehicle control and maneuvering in environments that induce illusory motion and displacement, and in situations where there is motion in a large area of the visual field. The impact of these effects on joystick control is described and discussed. We also describe the subjective sense of ownership attributed to hand-held objects when experiencing illusory self-motion and displacement.

“…To date, it is still widely believed that self-motion perception is determined by characteristics of sensory receptors, and it has been shown that vection induces subtle sensorimotor changes in arm movement control (Bringoux et al, 2012). Interestingly, self-motion perception can be modulated by high-level visual input like seeing another person in motion (Lopez et al, 2013, see Deroualle and Lopez, 2014, this issue, for a review on vestibular information in social cognition).…”

A growing number of studies in humans demonstrate the involvement of vestibular information in tasks that are seemingly remote from well-known functions such as space constancy or postural control. In this review article we point out three emerging streams of research highlighting the importance of vestibular input: (1) Spatial Cognition: Modulation of vestibular signals can induce specific changes in spatial cognitive tasks like mental imagery and the processing of numbers. This has been shown in studies manipulating body orientation (changing the input from the otoliths), body rotation (changing the input from the semicircular canals), in clinical findings with vestibular patients, and in studies carried out in microgravity. There is also an effect in the reverse direction; top-down processes can affect perception of vestibular stimuli. (2) Body Representation: Numerous studies demonstrate that vestibular stimulation changes the representation of body parts, and sensitivity to tactile input or pain. Thus, the vestibular system plays an integral role in multisensory coordination of body representation. (3) Affective Processes and Disorders: Studies in psychiatric patients and patients with a vestibular disorder report a high comorbidity of vestibular dysfunctions and psychiatric symptoms. Recent studies investigated the beneficial effect of vestibular stimulation on psychiatric disorders, and how vestibular input can change mood and affect. These three emerging streams of research in vestibular science are—at least in part—associated with different neuronal core mechanisms. Spatial transformations draw on parietal areas, body representation is associated with somatosensory areas, and affective processes involve insular and cingulate cortices, all of which receive vestibular input. Even though a wide range of different vestibular cortical projection areas has been ascertained, their functionality still is scarcely understood.

“…There are many examples in the literature of the dissociation between perception and action during the grasping (Aglioti, DeSouza & Goodale 1995, Haffenden, Schiff & Goodale 2001) and lifting of objects (Flanagan, Beltzner 2000, Bringoux, Lepecq & Danion 2012. The size-weight illusion affects the scaling of grip force in the first trials of a lifting task, but with repeated lifting movements the motor effect fades away, while the illusion persists (Flanagan, Beltzner 2000).…”

We investigated how artificial tactile feedback in the form of a skin-stretch affects perception of stiffness and grip force adjustment. During interactions with objects, information from kinesthetic and tactile sensors is used to estimate the forces acting on the limbs. These enable the perception of the mechanical properties of objects to form, and the creation of internal models to predict the consequences of interactions with these objects, such as feedforward grip-force adjustments to prevent slippage. Previous studies showed that an artificial stretch of the skin of the fingertips can produce a linear additive effect on stiffness perception, but it remains unclear how such stretch affects the control of grip force. Here, we used a robotic device and a custom-built skin-stretch device to manipulate kinesthetic and tactile information. Using a stiffness discrimination task, we found that adding artificial tactile feedback to a kinesthetic force can create the illusion of touching a harder spring which affects both perception and action. The magnitude of the illusion is linearly related to the amplitude of the applied stretch. We also isolated the contribution of tactile stimulation to the predictive and reactive components of grip force adjustment, and found that unlike in other cases of perceptual illusions, the predictive grip force is .

Significance StatementSensing forces, using kinesthetic and tactile modalities, is important for assessing the mechanical properties of objects, and for acting the objects while stabilizing grasp against slippage. A major challenge in understanding the internal representations that allow for a predictive grip force control during contact with objects is to dissociate the contribution of tactile and kinesthetic stimuli. To date, this contribution was investigated only in impaired cases either through local anesthesia or in patients with sensory impairment. Our study demonstrates using a programmable mechatronic device that artificially applied skinstretch creates an illusion of a greater load force that affects grip force control and stiffness perception. These results are applicable in tactile technologies for wearable haptic devices, teleoperation, robot-assisted surgery, and prosthetics.
