Sufficient Time-Frequency Resolution for Reproducing Vibrotactile Sensation
IEEE Transactions on Haptics, 2023 In vibrotactile stimuli, it is essential to reproduce realistic tactile sensations to enhance the immersiveness of applications. To reproduce more realistic tactile experiences, various tools have been proposed to fine-tune and design vibrotactile sensations. Considering the situation where users adjust parameters manually, providing tactile sensations

Resonance frequency selective electromagnetic actuation for high-resolution vibrotactile displays [PDF]
Sensors and Actuators A: Physical, 2020 Abstract Vibrotactile displays offer significant potential for conveying information through the sense of touch in a wide variety of applications. Spatial resolution of these displays is limited by the large size of actuators. We present a new selective electromagnetic actuation technique to control the vibrations of multiple tactile elements using a

Oscillatory Correlates of Vibrotactile Frequency Processing in Human Working Memory [PDF]
The Journal of Neuroscience, 2010 Previous animal research has revealed neuronal activity underlying short-term retention of vibrotactile stimuli, providing evidence for a parametric representation of stimulus frequency in primate tactile working memory (Romo et al., 1999). Here, we investigated the neural correlates of vibrotactile frequency processing in human working memory, using ...

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 ...

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 ...

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-

Modeling and Experimental Evaluation of Haptic Localization Using Electrostatic Vibration Actuators
IEEE Access, 2023 Touch screen devices have become ubiquitous in modern day-to-day lives. While smaller touchscreen devices provide enough user engagement with meaningful haptic feedback, large touch devices still lack meaningful haptic stimulation.

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 ...
