Open AccessIncreased temporal binding during voluntary motor task under local anesthesia
Temporal binding refers to a systemic bias in the perceived time interval between two related events, most frequently voluntary motor actions and a subsequent sensory effect. An inevitable component of most in...

Open AccessArtificial fast-adapting mechanoreceptor based on carbon nanotube percolating network
Most biological sensors preferentially encode changes in a stimulus rather than the steady components. However, intrinsically phasic artificial mechanoreceptors have not yet been described. We constructed a ph...

Human Self-touch vs Other-Touch Resolved by Machine Learning
Using a database of vibratory signals captured from the index finger of participants performing self-touch or touching another person, we wondered whether these signals contained information that enabled the a...

Harnessing tactile waves to measure skin-to-skin interactions
Skin-to-skin touch is an essential form of tactile interaction, yet there is no known method to quantify how we touch our own skin or someone else’s skin. Skin-to-skin touch is particularly challenging to meas...

“HaptiComm”, a Haptic Communicator Device for Deafblind Communication
When people are deaf and blind, daily life is made difficult owing to the lack of linguistic communication that is normally mediated by sight and hearing. The project described herein aims at hel** deafblind...

Review of Anthropomorphic Head Stabilisation and Verticality Estimation in Robots
In many walking, running, flying, and swimming animals, including mammals, reptiles, and birds, the vestibular system plays a central role for verticality estimation and is often associated with a head stabili...

Open AccessConfidence is higher in touch than in vision in cases of perceptual ambiguity
The inclination to touch objects that we can see is a surprising behaviour, given that vision often supplies relevant and sufficiently accurate sensory evidence. Here we suggest that this ‘fact-checking’ pheno...

Open AccessRadial trunk-centred reference frame in haptic perception
The shape of objects is typically identified through active touch. The accrual of spatial information by the hand over time requires the continuous integration of tactile and movement information. Sensory inpu...

Sensing with tools extends somatosensory processing beyond the body
The ability to extend sensory information processing beyond the nervous system1 has been observed throughout the animal kingdom; for example, when rodents palpate objects using whiskers2 and spiders localize prey...

Electromagnetic Actuator for Tactile Communication
Fingerspelling is a tactile code that enables linguistic communication with people who are Deafblind. We describe and undertake initial testing of a crucial component of a device that is designed to perform ta...

A Case of Perceptual Completion in Spatio-Temporal Tactile Space
We reproduced a perceptual phenomenon where a tactile stimulus moving on the fingertip jumps instantly over a gap but is felt as if the space of the gap was perceptually obliterated. This phenomenon was recent...

A Brief Overview of the Human Somatosensory System
This chapter provides an overview of the human somatosensory system. It is the system that subserves our sense of touch, which is so essential to our awareness of the world and of our own bodies. Without it, w...

Self-adjustment mechanisms and their application for orthosis design
Medical orthoses aim at guiding anatomical joints along their natural trajectories while preventing pathological movements, especially in case of trauma or injuries. The motions that take place between bone su...

Open AccessTouch uses frictional cues to discriminate flat materials
In a forced-choice task, we asked human participants to discriminate by touch alone glass plates from transparent polymethyl methacrylate (PMMA) plastic plates. While the surfaces were flat and did not exhibit...

Open AccessHaptic Edge Detection Through Shear
Most tactile sensors are based on the assumption that touch depends on measuring pressure. However, the pressure distribution at the surface of a tactile sensor cannot be acquired directly and must be inferred...

Dual Stage Options for Interface Designs Suitable for Haptic Interaction at the Micro-Nano Scales
Direct, manual interaction with the micro/nano scales is not straightforward because the objects at this scale obey unituitive physics. For instance, in ambient conditions at the micro-scale, capillary forces ...

Tactile Illusions
Tactile illusions are found when the perception of a quality of an object through the sense of touch does not seem to be in agreement with the physical stimulus.

Open AccessIllusory Tactile Motion Perception: An Analog of the Visual Filehne Illusion
We continually move our body and our eyes when exploring the world, causing our sensory surfaces, the skin and the retina, to move relative to external objects. In order to estimate object motion consistently,...

Recording Device for Natural Haptic Textures Felt with the Bare Fingertip
The perception of haptic textures depends on the mechanical interaction between a surface and a biological sensor. A texture is apprehended by sliding one’s fingers over the surface of an object. We describe h...

Haptic Shape Constancy Across Distance
To explore haptic shape constancy across distance, we measured perceived curvature thresholds of cylindrical shapes, cut out of acetal resin blocks. On each trial, blindfolded observers used their bare finger ...
