Exploring Vibrotactile Intensity Perception with Multiple Waveform Parameters

概要

It is known that by lengthening the duration of a vibrotactile stimulus or applying a damping or an increasing factor to the waveform, the perceived intensity is affected in different ways. This paper presents a vibrotactile presentation system assembled with a software waveform generator that enables comparison of the perceived intensity for different waveforms made by multiple parameters. The adjustable parameters are frequency, amplitude, and wave type for the basic part of the stimuli; in addition, it is possible to apply an exponential decay or increasing factor to the waveform by specifying the duration. Using the presented system, an easy comparison of the influence of different waveform parameters on the perception of intensity is possible. We conducted a preliminary experiment on a variety of waveshapes with and without damping using this system.

  振動知覚メカニズム

  振幅は直接知覚される強度と一対一で対応しているわけではありません。持続時間・減衰・位相スペクトルといった時間的な要因が振動の知覚強度をどう変えるのかを一連の実験で調べています。
