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

A closed-loop tactor frequency control system for vibrotactile feedback
CHI '05 Extended Abstracts on Human Factors in Computing Systems, 2005In this paper, we address the problem of maintaining a precise frequency in vibrating motors for use as vibrotactile cueing devices. Our solution utilizes a piezoelectric film sensor that measures the motor frequency and uses a feedback-loop circuit to dynamically adjust the motor power to maintain the target frequency. We confirmed the accuracy of the

Vibrotactile Perception: Differential Effects of Frequency, Amplitude, and Acceleration
2006 IEEE International Workshop on Haptic Audio Visual Environments and their Applications (HAVE 2006), 2006High-frequency vibrations are an essential part of numerous manipulation tasks. A promising research area in particular are telemanipulation tasks where vibrations occurring in the remote environment are fed back through tactile displays. Two experiments concerning the perception of vibrations were conducted.

Investigating the Effects of Intensity and Frequency on Vibrotactile Spatial Acuity
IEEE Transactions on HapticsVibrotactile devices are commonly used in applications for sensory substitution or to provide feedback in virtual reality. An important aspect of vibrotactile perception is spatial acuity, which determines the resolutions of vibrotactile displays on the skin.

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 ...
