Cortical activations induced by electrical versus vibrotactile finger stimulation using EEG

NeuroImage
Somatosensory evoked potentials (SEPs) recorded with electroencephalography offer insights into cortical responses to tactile stimulation, typically elicited through temporally precise electrical stimulation.

Spatially-limited attention to vibrotactile stimulation [PDF]

Perception & Psychophysics, 1970
Weak vibrotactile signals were presented to human Os, in some instances to the index finger alone, in other instances to the middle finger alone, and in still other instances to the two fingers simultaneously. When the 0 knew in advance of a trial which finger(s) would be presented a signal, no spatial summation resulted, that is, the sensitivity of ...

Vibrotactile versus visual stimulation in learning the piano

Interacting with Computers
Abstract Vibrotactile stimulation has been explored to accelerate the acquisition of motor skills involving finger movements (Markow et al., 2010; Seim et al., 2017; Gemicioglu et al., 2022). This study evaluates the effectiveness of vibrotactile stimulation compared to visual feedback in learning a 14-note one-handed tune on the piano ...

Design and Modeling of a High‐Displacement, Skin‐Integrated Flexible Electromagnetic Actuator for Haptic Interfaces in Virtual Reality

Advanced Robotics Research, EarlyView.
A flexible, skin‐integrated electromagnetic actuator is developed for wearable virtual/augmented reality (VR/AR) haptic systems. A tunable design model enables control over displacement and resonance frequency. The system is validated through a custom VR application with a 6 × 4 actuator array, demonstrating real‐time, spatially targeted tactile ...

Evaluating the Optimum Distance between Voice Coil Actuators Using the Relative Point Localization Method on the Forearm

Actuators, 2022
While vibrotactile stimulation shows promise for sensory substitution devices, a crucial question concerns vibrotactile spatial resolution. We examined the optimum distance between three voice coil actuators (model: lofeltL5) on the forearm.
