Vehicle drivers receive tactile feedback from steering-wheel vibration that depends on the frequency and magnitude of the vibration. From an experiment with 12 subjects, equivalent comfort contours were determined for vertical vibration of the hands at two positions with three grip forces. The perceived intensity of the vibration was determined using the method of magnitude estimation over a ra...

Article history: Received: 14.10.2013. Received in revised form: 15.11.2013. Accepted: 09.12.2013. Fire-induced vibration of four panels A-D has been studied and also relevant furnace temperature, temperature gradient, deflections and cracking distributions introduced. Time-domain analysis indicating vibration intensity has important relationships with boundary constraints. According to vibrati...

Whole body vibration (WBV) platforms are currently used for muscle training and rehabilitation. However, the effectiveness of WBV training remains elusive, since scientific studies vary largely in the vibration parameters used. The origin of this issue may be related to a lack in understanding of the training intensity that is imposed on individual muscles by WBV. Therefore, this study evaluate...

In this paper we assess the potential of rich tactile notifications on mobile phones. Many mobile phone users use vibration output for various types of notification on their phone. Currently, tactile output in phones is limited to one single actuator that can potentially present patterns based on different vibration intensity over time. To explore the possible design space, we conducted experim...

A new acoustical parameter, called Intensity of Acoustic Radiation (IAR), was recently defined, and resulted very well related with mechanical vibration of sound source, being able to quantify the sound efficiency of musical Instruments In this paper the IAR was experimentally measured on Persian string musical Instruments. IAR relates mechanical vibration of surface (e.g. soundboards) and soun...

Vibrotactile rendering is one of the most popular means for improving the user interface of a mobile device, but the availability of related perceptual data that can aid vibrotactile effect design is not currently sufficient. The present paper reports data from a series of psychophysical studies designed to fill this gap. In Experiment I, we measured the absolute detection thresholds of sinusoi...
