Abstract: Disclosed are an electronic system for controlling a memo object in a virtual space and an operating method thereof. The disclosed electronic system comprises: an electronic device, which detects, on the basis of an input from a user, the motion of writing on a reference object in a virtual space; and a display device, which displays a scene in the virtual space corresponding to the viewpoint of the user and provides the scene to the user and, in response to the case where the reference object is included in the scene, displays on the reference object the writing corresponding to the writing motion, on the basis of information transmitted from the electronic device, wherein the reference object in the virtual space is disposed on the surface of the electronic device, at least one of the two hands of the user is tracked and displayed in the virtual space, and the tracked hand of the user controls one or more objects in the virtual space.

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.
