Abstract: PURPOSE: A method for providing contact information between a 3D cursor and a virtual object in a 3D virtual environment and an image providing device performing the same are provided to obtain information without a particular eye movement by supplying visual information to a location of an object close to the contact of the 3D cursor. CONSTITUTION: A progress direction of a 3D cursor is predicted, a contact candidate object is selected by considering the predicted progress direction(S11). A ratio of a remaining distance for the 3D cursor to contact the contact candidate object is calculated(S12). Sub devices surrounding a convergent center point of the contact candidate object are displayed. A ratio of a distances between the sub devices and the contact candidate object is variably displayed according to the remaining distance(S30). [Reference numerals] (AA) Start; (BB) End; (S10) Predicting progress direction of 3D cursor; (S11) Selecting contact candidate object by considering predicted progress direction; (S12) Calculating ratio of remaining distance for 3D cursor to contact contact candidate object; (S30) Varying transparency of contact candidate object according to ratio of remaining distance
