Abstract: Provided is a method for controlling an interaction undo/redo interface. The method for controlling an interaction undo/redo interface includes causing interaction to be performed between a plurality of virtual objects created in a three-dimensional virtual space and a user, wherein the interaction is performed by recognition of the user's gesture, and activating the interaction undo interface or the interaction redo interface in response to a gesture not corresponding to the user's interaction gesture.

Abstract: A method and apparatus for motion capture interface using multiple fingers are disclosed. The method includes measuring a position of an end of a middle finger of an actual hand in a state in which the actual hand is spread, deriving a starting reference position of the middle finger of the actual hand, and calculating a length of the middle finger of the actual hand. The method further includes recognizing a relationship between starting reference positions of a thumb, an index finger, a middle finger, and a wrist based on using a virtual hand reference model that models a virtual hand to be controlled.
