Abstract

We developed a device that presents information through modulated vibrations. No previous studies evaluating the human cognition of tactile-based modulated vibrations have, to our knowledge, been conducted before. We propose evaluating cognitive discrimination of modulated vibration stimuli based on event related potential (ERP). Modulated vibrations consist of high f_H (40-500Hz) and low f_L (2-20Hz) band components, and are represented as points on the f_H vs. f_L plane. We measure discrimination threshold distribution on the f_H vs. f_L plane using ERP-based evaluation. An experiment we conducted identify discrimination thresholds in four directions about a reference (nontarget) point.
