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 robot motion data processing system has a data extraction module for intermittently extracting restoration motion data from a successive input motion trajectory formed for controlling a motion of a robot, and a data restoration module for restoring an output motion trajectory approximate to the input motion trajectory by using restoration motion data extracted from the data extraction module. The output motion trajectory is restored to satisfy a condition that the robot operating according to the output motion trajectory does not exceed a hardware operation limit of the robot.

Abstract: 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.

Abstract: A robot control system includes a detecting device configured to detect an obstacle, and a control device configured to control a robot by planning a driving path of the robot. The control device generates a road map space including nodes containing information about a state of the robot and edges connecting the nodes. Also, the control device checks whether the obstacle detected by the detecting device overlaps with the nodes, removes an overlapped node, generates a driving path by sampling remaining nodes and edges, and checks whether the edges of the driving path overlap with the obstacle. When there is no overlapped edge, the control device determines the driving path on the road map space to plan a path along which the robot drives without colliding with the obstacle.
