Abstract: Disclosed are an electronic device for carrying out three-dimensional sketching, an electronic device, and an operating method thereof. The disclosed electronic device comprises at least one processor which arranges a reference plane onto a three-dimensional virtual space including an object expressed by a plurality of lines, and generates a joint, which applies to a first part of the object, on the basis of repetitive movement of the first part overlapping with the reference plane, while a first touch input by a user on the reference plane is being maintained. The joint is determined according to the component type of the reference plane to which the first touch input is inputted, and the number of second touch inputs, of the user, for controlling the repetitive movement of the first part.

Abstract: Disclosed are an electronic system for performing control over a virtual reality space, an electronic device, and a method for operating same. The disclosed electronic system comprises: an electronic device which receives, as one or more touch gestures, control of a virtual reality space and/or an object within the virtual reality space and displays a first screen according to a corresponding first view frustum within the virtual reality space; and an HMD which is worn on the user's head and displays a second screen of the virtual reality space according to the head direction of the user at a time point corresponding to the second view frustum within the virtual reality space.
