Vibrotactile adaptation enhances frequency discrimination
The Journal of the Acoustical Society of America, 1994Human vibrotactile frequency discrimination (with respect to a 25-Hz standard stimulus, 20 dB above unadapted detection threshold) was measured on the thenar eminence and index fingerpad, using two-interval forced-choice tracking. Measurements were made in the unadapted state and following exposure to 25-Hz adapting stimuli of various amplitudes.

Vibrotactile Alphabets: Time and Frequency Patterns to Encode Information
IEEE Transactions on Haptics, 2021Although many tactual communication methods have been developed over the past decades, few of them have been widely adopted in everyday lives. In this paper, we investigate the ability to deliver text messages using patterns of vibrations. By manipulating the duration and frequency of vibrations, we designed two vibrotactile alphabets, i.e.

Vibrotactile frequency for encoding a speech parameter
The Journal of the Acoustical Society of America, 1977Frequency of vibration has not been widely used as a parameter for encoding speech-derived information on the skin. Where it has been used, the frequencies employed have not necessarily been compatible with the capabilities of the tactile channel, and no determination was made of the information transmitted by the frequency variable, as differentiated ...

Vibrotactile amplitude and frequency discrimination in temporomandibular disorders
Pain, 1998The purpose of this study was to determine whether the elevation in vibrotactile detection threshold, found in many individuals with temporomandibular disorders (TMD), is paralleled by suprathreshold impairments. Participants with TMD were compared with pain-free control subjects in their ability to discriminate on the basis of differences in amplitude

Discrimination of Vibrotactile Stimuli: Effects of Frequency Variation
Volume 1: Acoustics, Vibration, and Phononics, 2023Abstract This paper reports on an empirical study that investigated the effect of frequency on the acuity of spatial localization on the skin of the forearm, as well as differences in localizability at different locations on the forearm.

The localization of low- and high-frequency vibrotactile stimuli
The Journal of the Acoustical Society of America, 1990Four experiments were conducted to determine whether spatial localization on the skin varied in acuity as a function of frequency of vibratory stimulation. The glabrous skin of the palm over the hypothenar eminence was selected as the site for stimulation by two frequencies, one at 25 Hz to stimulate non-Pacinian receptors, and one at 250 Hz to excite ...

Vibrotactile Frequency Discrimination in Human Hairy Skin
Journal of Neurophysiology, 2006The human capacity for vibrotactile frequency discrimination has been compared directly for glabrous and hairy skin regions by means of a two-alternative, forced-choice psychophysical procedure in five subjects. Sinusoidal vibratory stimuli, delivered by means of a 4-mm-diam probe, were first used to obtain detection threshold values for the two skin ...

Is there low frequency vibrotactile temporal summation?
Scandinavian Journal of Psychology, 1981Reaction times of subjects to threshold vibratory stimuli of various durations and frequencies were measured simultaneously with the thresholds in order to test whether more time is needed for the detection of stimuli of long than short duration at threshold intensities.

Contribution of within- and cross-channel information to vibrotactile frequency discrimination
Brain Research, 2013Vibrotactile stimuli normally activate multiple information-processing channels starting from different types of mechanoreceptors, and the most sensitive channel alternates depending on the range of vibration frequency. How the tactile system encodes vibration frequency using within-channel information (e.g., the temporal pattern of neural activity of ...

The effects of duration and frequency on the perception of vibrotactile stimulation on the neck
2016 IEEE Haptics Symposium (HAPTICS), 2016The aim of this current study is to determine whether the neck is a viable location to receive tactile directional information to substitute a vestibular loss. While wearing a vibrotactile neck device with 14 motors equally positioned around the neck, participants were asked to detect the exact location of the delivered stimulus delivered.
