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.

Method for controlling interaction interface and device for supporting the same

Provided are a user interface device and a control method thereof for supporting easy and accurate selection of overlapped objects. The user interface device is a device for providing a user interface applied to a three-dimensional (3D) virtual space in which a plurality of virtual objects is created, and includes a gaze sensor unit to sense a user's gaze, an interaction sensor unit to sense the user's body motion for interaction with the virtual object in the 3D virtual space, a display unit to display the 3D virtual space, and a control unit to, when the user's gaze overlaps at least two virtual objects, generate projection objects corresponding to the overlapped virtual objects, wherein when an interaction between the projection object and the user is sensed, the control unit processes the interaction as an interaction between the virtual object corresponding to the projection object and the user.

User interface device and control method thereof for supporting easy and accurate selection of overlapped virtual objects

An apparatus for creating virtual joint sensation is provided. The apparatus includes: a controlling part for creating control signals for controlling respective user's joints by referring to information on torques to be applied to the respective user's joints, wherein the information on the torques is acquired by analyzing information on forces to be applied to the user's body contacting a virtual object; and a torque-applying part, including one or more torque-applying units worn on the respective user's joints, for giving the torques to the respective user's joints by using the control signals.
