Reporters obtained the following quote from the background information supplied by the inventors: "As communication technology is developed, portable terminals (e.g., smart phones, tablet PCs, and the like) are being widespread. The portable terminal provides an integrated user's function by adding various functions besides a voice call, a text call, and an image call service. Recently, advances in a portable terminal equipped with a touch screen are being developed. The portable terminal equipped with the touch screen is an input device as well as a display device performing an input and a display of the information in one screen.
"Some portable terminals provide a pen such as a stylus pen as an input tool besides a touch using a user's finger. In operating the portable terminal, the user may use the more detailed touch by using a pen input means. Using a touch pen, a user may select and operate a specific area of a display unit which supports for a touch function more delicately since the pen has a pen tip which is sharper than a finger. Therefore, a method of increasing the user's convenience is developed by providing more various functions by using the touch pen."
In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventor's summary information for this patent application: "To address the above-discussed deficiencies, it is a primary object to provide a method and an apparatus for recognizing a figure which is drawn on a screen, and controlling a figure which can increase fun and convenience to the user as well as increase an operability of the terminal by controlling the recognized figure with various touch pen movements.
"In accordance with an aspect of the present disclosure, a method for controlling a figure includes recognizing a figure which is input by handwriting on a touch screen, displaying one or more variable points to which a controlling function of a figure is mapped on a trajectory of the recognized figure, detecting a touch input that selects one of the variable points, determining whether a controlling function execution request of the recognized figure is detected based on at least one of a pressure information and a touch gesture information corresponding to the detected touch input, and executing the controlling function of the figure corresponding to the selected variable points when the controlling function execution request is detected.
"In accordance with another aspect of the present disclosure, an apparatus for controlling a figure includes: a touch screen configured to detect a handwriting input during operation of an editor mode, and display an input effect corresponding to the handwriting input; and a controller configured to control to recognize a figure input by a handwriting on the touch screen, display one or more variable points to which a controlling function of a figure is mapped on a trajectory of the recognized figure, detect a controlling function execution request of the recognized figure based on at least one of a pressure information and a touch gesture information corresponding to a touch input when a touch input that selects one of the variable point is detected, and execute the controlling function of the figure corresponding to the selected variable point in response to the function execution request.
"Before undertaking the DETAILED DESCRIPTION below, it may be advantageous to set forth definitions of certain words and phrases used throughout this patent document: the terms 'include' and 'comprise,' as well as derivatives thereof, mean inclusion without limitation; the term 'or,' is inclusive, meaning and/or; the phrases 'associated with' and 'associated therewith,' as well as derivatives thereof, may mean to include, be included within, interconnect with, contain, be contained within, connect to or with, couple to or with, be communicable with, cooperate with, interleave, juxtapose, be proximate to, be bound to or with, have, have a property of, or the like; and the term 'controller' means any device, system or part thereof that controls at least one operation, such a device may be implemented in hardware, firmware or software, or some combination of at least two of the same. It should be noted that the functionality associated with any particular controller may be centralized or distributed, whether locally or remotely. Definitions for certain words and phrases are provided throughout this patent document, those of ordinary skill in the art should understand that in many, if not most instances, such definitions apply to prior, as well as future uses of such defined words and phrases.
