Discriminating Vibrotactile Signals: The Relative Roles of Amplitude and Frequency
ActuatorsVibrotactile 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.

Integration of vibrotactile frequency information beyond the mechanoreceptor channel and somatotopy. [PDF]
Sci Rep, 2017 AbstractA wide variety of tactile sensations arise from the activation of several types of mechanoreceptor-afferent channels scattered all over the body, and their projections create a somatotopic map in the somatosensory cortex. Recent findings challenge the traditional view that tactile signals from different mechanoreceptor-channels/locations are ...

The Vibrotactile Working Memory for Frequency [PDF]
, 2021 Abstract A hallmark of working memory (WM) is its limited capacity. While visual and verbal domains of WM are able to store multiple items, the capacity of parametric vibrotactile WM (vtWM) has not yet been established for supra-threshold, one-dimensional sensory vibrotactile frequencies. The present study extends the standard delayed match-to-

Vibrotactile frequency discrimination [PDF]
Perception & Psychophysics, 1975 Thresholds for vibrotactile discrimination of pulse interval were determined for pulse frequencies between 1 and 384 Hz. The results point to a temporal resolution significantly more accurate than that demonstrated in earlier studies. Although touch as a vibratory sensor is in general much inferior to audition, the present results show a striking ...

Integration of auditory and vibrotactile stimuli: Effects of frequency [PDF]
The Journal of the Acoustical Society of America, 2010 Perceptual integration of vibrotactile and auditory sinusoidal tone pulses was studied in detection experiments as a function of stimulation frequency. Vibrotactile stimuli were delivered through a single channel vibrator to the left middle fingertip. Auditory stimuli were presented diotically through headphones in a background of 50 dB sound pressure ...

Impaired vibrotactile sense in children and adolescents with type 1 diabetes - Signs of peripheral neuropathy. [PDF]
PLoS ONE, 2018 To investigate whether multi-frequency vibrometry can identify individuals with elevated vibration perception thresholds (VPTs), reflecting impaired vibrotactile sense, among children and adolescents with type 1 diabetes.In 72 pediatric patients with ...

Vibrotactile frequency for encoding speech parameters [PDF]
The Journal of the Acoustical Society of America, 1976 Frequency 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 ...
