VIRTUAL FORCE SENSE PRESENTATION DEVICE AND VIRTUAL FORCE SENSE PRESENTATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To virtually present an arrangement and a shape of a three dimensional virtual object according to a tactile sense and a force sense.;SOLUTION: A virtual power sense presentation device for presenting positional information on a virtual space of a hand of a user as an object to which a sense is transmitted and a power sense by giving a load of the power sense on the hand of the user comprises feature extracting means for extracting feature information on a shape of the virtual object, parameter setting means for setting a parameter for presenting the virtual object, finger position detecting means for detecting positional information of a virtual pointer for a finger of the user, three dimensional coordinate analyzing means for analyzing a positional relationship on a three dimensional space coordinate including a minimum distance and a unit direction vector on the basis of three dimensional positional data of the virtual object included in the parameter and the positional information of the virtual pointer, and presentation force computing means for computing presentation force information for presenting by a tactile sense and a power sense on the basis of a predetermined presentation condition corresponding to movement information of the virtual pointer based on the positional relationship between the virtual pointer and the virtual object and the feature information.;COPYRIGHT: (C)2012,JPO&INPIT
