2P1-O12 情報圧縮から振動触覚素材テクスチャの知覚特性を知る : 第二報:主観的品質を説明する客観指標の開発(触覚と力覚(2))

Abstract

This study develops an objective index that well describes vibrotactile material textures' quality changes caused by data compression processes. We introduce a linear combination of the power and amplitude spectra that are weighted by the inverse of a detection threshold curve of vibrotactile stimuli. This combination describes the quality deterioration of compressed textures to an accuracy of approximately 80%. These objective indices enhance the development of the lossy data compression algorithms and assist the search for physical quantities that affect perception of vibrotactile textures.
