Optimality of multisensory integration while compensating for uncertain visual target information with artificial vibrotactile cues during reach planning

Journal of NeuroEngineering and Rehabilitation
Background Planning and executing movements requires the integration of different sensory modalities, such as vision and proprioception. However, neurological diseases like stroke can lead to full or partial loss of proprioception, resulting in impaired ...

Tactile-Sight: A Sensory Substitution Device Based on Distance-Related Vibrotactile Flow

International Journal of Advanced Robotic Systems, 2013
Sensory substitution is a research field of increasing interest with regard to technical, applied and theoretical issues. Among the latter, it is of central interest to understand the form in which humans perceive the environment.

Biomimetic 3D Tactile Sensor System With Neuromorphic Encoding for Fascicle‐Level Feedback

Advanced Intelligent Systems, EarlyView.
A 3D biomimetic tactile sensor system converts skin‐like mechanical interactions into neural stimulation‐ready spike patterns. Embedded slow‐ and fast‐adapting sensors distinguish sustained pressure from transient touch, while neuromorphic encoding preserves their temporal signatures.

Artificial structures for human‐machine interfaces with closed‐loop interaction

FlexMat, EarlyView.
Artificial structures bridge sensing and feedback in closed‐loop human‐machine interfaces by providing geometry‐enabled mechanical and functional programmability. This review maps the role of artificial structures in diverse sensing modalities and feedback strategies, and illustrates their integration into closed‐loop interaction systems, highlighting ...

A Design Specifications Template for Wearable Haptic Interfaces: A Case Study for Robotic Gripper Applications

Journal of Field Robotics, EarlyView.
ABSTRACT Wearable haptic interfaces are increasingly important for enhancing human robot collaboration, particularly in decision critical tasks that require intuitive and reliable interaction. Despite advances in wearable systems, existing designs often lack a structured framework that systematically integrates sensing, actuation, control, and user ...

Vibrotactile intensity perception: Predominant influence of afferents recruited remote from stimulus site

The Journal of Physiology, EarlyView.
Abstract figure legend We delivered trains of brief mechanical pulses to the fingertips of subjects to investigate vibrotactile intensity perception. Some stimuli consisted of bursts of up to four pulses. Simulated responses of the tactile afferent population across the hand revealed that afferents innervating the skin directly under the probe reliably

Vibrotactile enhancement of musical engagement

Scientific Reports
Sound is sensed by the ear but can also be felt on the skin, by means of vibrotactile stimulation. Only little research has addressed perceptual implications of vibrotactile stimulation in the realm of music.

Acceleration-Dependent Effects of Vibrotactile Gamma Stimulation on Cognitive Recovery and Cholinergic Function in a Scopolamine-Induced Neurotoxicity Mouse Model

Biomedicines
Background: Alzheimer’s disease is a progressive neurodegenerative disorder characterized by cognitive decline and memory loss. Gamma (γ) oscillations are closely linked to learning and memory, and recent interest has grown around Gamma ENtrainment Using

Vibrotactile mapping of the upper extremity: Absolute perceived intensity is location-dependent; perception of relative changes is not

Frontiers in Neuroscience, 2022
Vibrotactile sensation is an essential part of the sense of touch. In this study, the localized vibrotactile sensation of the arm-shoulder region was quantified in 10 able-bodied subjects.
