A Study to Representation System of Force Sensation with Object Manipulation in Virtual Space

摘要

Methods of force sensation representation for the virtual object manipulation in virtual space produced by the ordinary computer device environment is investigated. It is considered that there are five main elements of giving the force sensation, when the object in virtual space is manipulated by the virtual hand. The 3-dimensional graphical virtual space in which the virtual hand raise an object where these five elements act independently. Twenty five subjects evaluated the gravity sensation accompanied by the operation. The validity analysis of the five force sensation elements is performed on the evaluated values. The validity and the reliability of each element is examined.
