PROBLEM TO BE SOLVED: To automatically evaluate acuity of pseudo force sense which is presented by a pseudo force sense generator.SOLUTION: An evaluation device acquires an estimated value of acuity of pseudo force sense, based on a physical amount corresponding to at least one of change of a position and change of force, by vibration of a vibration part acquired by measuring the vibration part of a pseudo force sense generator which is gripped by a human being or which simulates a state of being gripped by a human being.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】疑似力覚発生装置が呈示する疑似力覚の明瞭度の評価を自動化する。【解決手段】評価装置は、人に把持された状態または人に把持された状態を模した状態の疑似力覚発生装置の振動部を測定して得られた振動部の振動による位置の変化および力の変化の少なくとも一方に応じた物理量に基づき、疑似力覚の明瞭度の推定値を得る。【選択図】図2
