“…2) suggest the involvement of the Pacinian channel in the mediation of perception of vibration at the foot, as found in studies of absolute thresholds at the palm of the whole hand [6,[23][24]. The perception thresholds for the foot determined in Experiment 1a have been compared with perception thresholds for the hand and the seat in Morioka and Griffin [25]; it was suggested that the thresholds at the hand, the foot and the seat at frequencies greater than 80 Hz were mediated by the same psychophysical channel.…”

“…Figure 16 shows a comparison between the annoyance ratings measured in this pilot test and the ratings predicted using the model in equation (11). The Pearson's correlation coefficient between the measured and predicted annoyance ratings shown in this figure is 0.91 (p < 0.0001).…”

“…In the model relating the positions of the stimuli on the four perceptual dimensions to the Perceived Annoyance Ratings [see equation (11)], it can be noted that each of the coefficients in the model reached statistical significance. This suggests that further work is needed to find objective correlates which better describe the third and fourth perceptual dimensions.…”

“…As is the case for environmental noise, this may be due to both factors not related to the vibration exposure [8,9] and an inadequacy in the single figure vibration exposure descriptors to describe human response. Although a substantial amount of fundamental psychophysical work has been conducted for the human response to vibration such as investigations into subjective magnitude [10], perception thresholds [11], and equal comfort contours [12], there is a lack of understanding regarding the perception of complex vibration from real sources.…”

This paper presents a study investigating seated subjects' perception of railway induced groundborne vibration in the vertical direction. Previous studies into the perception of railway induced vibration have treated this phenomenon as a unidimensional problem. The aim of the study detailed in this paper is to determine if the perception of railway induced groundborne vibration is multidimensional in nature and if the resulting perceptual dimensions can be related to a measure of annoyance. Twenty-one subjects took part in paired comparison tests of similarity and annoyance. These tests were conducted using fourteen measured vibration stimuli selected to be representative of groundborne vibration induced by railway activities in the United Kingdom. Through multidimensional scaling analysis, it is shown that the perception of railway induced vibration is dependent on up to four perceptual dimensions. These dimensions relate to energy in the 16 Hz 1/3 octave band (a 16Hz ), energy in the 32 Hz 1/3 octave band (a 32Hz ), the duration of the train passage (T 10dB ), and the modulation frequency of the envelope of the signal (f mod ). These perceptual dimensions are shown to be related to single figure Perceived Annoyance Ratings (A) by the following relationship: A = −0.40 + 4.57a 16Hz + 3.18a 32Hz + 0.02T 10dB + 0.02f mod . Finally, the single figure Perceived Annoyance Ratings are related to categorical ratings of annoyance via a logistic regression model. These findings 1 confirm the hypothesis that the perception of complex vibration stimuli is multidimensional and can be described by a small number of perceptual dimensions.

Vibrotactile pedals: provision of haptic feedback to support economical driving

2013

The use of haptic feedback is currently an underused modality in the driving environment, especially with respect to vehicle manufacturers. This exploratory study evaluates the effects of a vibrotactile (or haptic) accelerator pedal on car driving performance and perceived workload using a driving simulator. A stimulus was triggered when the driver exceeded a 50% throttle threshold, past which is deemed excessive for economical driving. Results showed significant decreases in mean acceleration values, and maximum and excess throttle use when the haptic pedal was active versus a baseline condition. As well as the positive changes to driver behaviour, subjective workload decreased when driving with the haptic pedal verses when drivers were simply asked to drive economically. The literature suggests that the haptic processing channel offers a largely untapped resource in the driving environment, and could provide information without overloading the other attentional resource pools used in driving.Keywords: Driving; haptic feedback; eco-driving; acceleration; vibrotactile; workload Statement of RelevanceOverloaded or distracted drivers present a real safety danger to themselves and others. Providing driving related feedback can improve performance but risks distracting them further, however giving such information through the underused haptic processing channel can provide the driver with critical information without overloading the driver's visual channel.
