Effects of Digital Vibrotactile Speech Feedback on Overt Stuttering Frequency
Perceptual and Motor Skills, 2009Fluency-enhancing speech feedback, originating from internally or externally generated sources via auditory or visual sensory modalities is not restricted to a specific sensory modality or signal origination. Research suggests that externally generated digital vibrotactile speech feedback serves as an effective fluency enhancer. The present purpose was

Coding of vibrotactile stimulus frequency by Pacinian corpuscle afferents
The Journal of the Acoustical Society of America, 1991Psychophysical and electrophysiological techniques were used to study the encoding and processing of information about the frequency content of vibrational stimuli applied to glabrous skin in humans and cats. Trained human subjects were asked to discriminate changes in stimulus frequency and harmonic content for pairs of mono- and diharmonic sinusoidal

The role of frequency selectivity in measures of auditory and vibrotactile temporal resolution
The Journal of the Acoustical Society of America, 1992The purpose of this study was to compare the role of frequency selectivity in measures of auditory and vibrotactile temporal resolution. In the first experiment, temporal modulation transfer functions for a sinusoidally amplitude modulated (SAM) 250-Hz carrier revealed auditory modulation thresholds significantly lower than corresponding vibrotactile ...

Vibrotactile Frequency Recognition: Forward and Backward Masking Effects
The Journal of General Psychology, 1986Forward and backward vibrotactile recognition masking was investigated in 4 subjects with 240-Hz and 160-Hz targets of 20 ms duration and four 200-Hz masks, using interstimulus intervals (ISIs) ranging from -500 to 500 ms. Two of the masks (short) were 20 ms and two (long) were 200 ms in duration.

Vibrotactile masking: Effects of stimulus onset asynchrony and stimulus frequency
The Journal of the Acoustical Society of America, 1989Vibrotactile thresholds for the detection of a 50-ms vibratory stimulus on the thenar eminence of the hand were measured in the presence of and in the absence of a 700-ms suprathreshold vibratory masking stimulus. When thresholds were measured in the presence of the masking stimulus, stimulus onset asynchrony (SOA) was varied so that backward ...

Perceived Frequency of Aperiodic Vibrotactile Stimuli Depends on Temporal Encoding
2018Mechanical transients and events arising during dexterous manipulation are detected by tactile afferents. Naturally occurring vibrotactile stimuli have a mix of frequencies, which creates complex afferent discharge patterns. Psychophysical correlates of these complex discharge patterns could be useful tools to gain greater insights into tactile coding ...

Vibrotactile rendering is an emerging interaction method for information transmission in mobile devices, replacing or supplementing visual and auditory displays. To design effective vibrotactile actuators or display algorithms, an understanding of the perceived intensity (strength) of their vibrations is essential.

Vibrotactile temporal summation: effect of frequency.
Sensory processes, 1977Temporal summation of vibrotactile stimuli was measured at four frequencies (25, 40, 80, and 160 Hz) using a large contactor. Stimulation at 160 Hz gave temporal summation comparable in amount to that reported in previous studies. Stimulation at 25, 40, and 80 Hz gave less summation. The presence of summation at low frequencies is unexpected in view of
