An Activity Classification for Vibrotactile Phenomena [PDF]

, 2006
We observe that the recent availability of audio-haptic actuators allow richer vibration content to be available in commercial devices. However, we note that consumers are unable to take advantage of these rich experiences, mainly due to the lack of a descriptive language for vibration. We analyze the current methods for classifying vibrations.

The influence of prior experience and expected timing on vibrotactile discrimination

Frontiers in Neuroscience, 2013
Vibrotactile discrimination tasks involve perceptual judgements on stimulus pairs separated by a brief interstimulus interval (ISI). Despite their apparent simplicity, decision making during these tasks is biased by prior experience in a manner that is ...

A psychophysical investigation on vibrotactile sensing for transradial prosthesis users

Cogent Engineering, 2018
The absence of tactile sensory feedback in transradial prosthetic hands is one of the major contributing factors for these devices to be rejected by users.

Vibrotactile signals can aid recognition of spectrally degraded speech signals [PDF]

JASA Express Letters
The potential utility of providing low-frequency portions of speech signals through vibrotactile stimulation as an aid to speech recognition by cochlear implant recipients was examined. Sixty-five young adults with normal hearing heard four-channel noise-

Discriminating Vibrotactile Signals: The Relative Roles of Amplitude and Frequency

Actuators
Vibrotactile interfaces commonly encode information using changes in stimulus amplitude and frequency, yet it remains unclear how reliably these parameters can be distinguished when spatial cues are unavailable.

Continuous Vibration-Driven Virtual Tactile Motion Perception Across Fingertips

Sensors
Motion perception is a fundamental function of the tactile system, essential for object exploration and manipulation. While human studies have largely focused on discrete or pulsed stimuli with staggered onsets, many natural tactile signals are ...

Identification of anatomical locations: its relevance for vibrotactile perception of individuals with Parkinson's disease

BioMedical Engineering OnLine
Background Vibrotactile input is a useful sensory cue for individuals with Parkinson's Disease (PD) to overcome freezing of gait (FoG). For this input to serve as a cue, its accurate perception is required.
