Abstract:
Methods, systems, and devices for guiding a subject back within the recognizable visual range of a multimedia system are described. According to one of the described methods, when it is determined that the target has left the recognizable range of the multimedia system, sensor information is acquired from a portable electronic device (or controller) the user has been using to control the multimedia system, and the acquired sensor information is used to determine where the user is, relative to the recognizable range. In one example, the user is asked to make a gesture with the portable electronic device, and the sensor information concerning that gesture is used to determine the user's relative location. In another example, the sensor information recorded at the time the user left the recognizable range is used to determine the user's relative location.
Abstract:
A method and an apparatus for controlling a display in order to secure an appropriate viewing distance between a digital device and a user who is viewing the digital device is provided. Accordingly, the method determines whether an object exists within a hazardous viewing distance using a 3D camera function provided in the digital device. If it is determined that an object exists within the hazardous viewing distance, the digital device detects a face or eyes from 2D images photographed by the camera. Next, the direction of the face is determined on the basis of the detected results, and it is determined whether a user is viewing a display screen of the digital device based on the determination. If it is determined that a user is viewing a display screen of a digital device, the digital device generates a warning that the user is positioned within a hazardous viewing distance.
Abstract:
A method for controlling a user interface of an apparatus to enable intuitive manipulation for an object included in an image is provided. An object with deeper depth in a rear image of the apparatus may become selectable when the user holds a user input means close to the apparatus, while an object with shallower depth in the rear image may become selectable when the user draws the user input means away from the apparatus, thereby allowing the user to intuitively select an object in the rear image.
Abstract:
A camera apparatus and method enabling a user to conveniently control an operation of the camera apparatus according to a gesture of a subject for photography input through a lens of a camera, and a method of controlling the camera apparatus are provided. The method includes generating a current frame by receiving an image input through a camera; comparing the current frame and one or more previous frames stored before the current frame and detecting a gesture of a subject for photography included in the current frame and the one or more previous frames; determining whether the gesture is a gesture UI; and when the gesture is the gesture UI, executing an operation corresponding to the gesture UI.
Abstract:
A method and apparatus for setting a font size in a mobile terminal having a touch screen. During a font size setting mode, an area of a region where a user's finger touches the screen is detected. A font size corresponding to the detected area is determined from among preset font sizes, and the determined font size is displayed in a specific region on the touch screen. If a font size setting request to the displayed font size is received from the user, the displayed font size is stored for a subsequent display on the touch screen.
Abstract:
A method and an apparatus are provided for providing additional information service in a mobile communication terminal. A microphone receives a sound signal including an audible frequency band and an inaudible frequency band. Additional information related to the service is detected in the inaudible frequency band included in the sound signal. The detected additional information is extracted from the sound signal. Data for providing the service is acquired based on the extracted additional information. A service screen is displayed based on the acquired data.
Abstract:
A method and apparatus for extracting three-dimensional distance information from a recognition target is provided, which enables a gesture input from a user to be correctly recognized using distance information from the recognition target, and at the same time makes it possible to efficiently save power required for detection of the gesture input. The method includes determining if a recognition target exists within a predetermined range; when the recognition target exists within the predetermined range, generating a 3D image for the recognition target; and calculating a distance to the recognition target by using the 3D image.
Abstract:
A portable terminal and a method for protecting a displayed object on a screen of a portable terminal are provided. The method includes detecting an input on the screen; forming an area corresponding to a position of the detected input; and displaying a part of an object corresponding to the formed area differently from another part of the object in an area outside of the formed area.
Abstract:
An apparatus and method of a portable terminal outputting a sound effect are provided. An operation method of the portable terminal includes sensing an input, identifying a handwriting tool used for the input and a handwriting face displayed, and outputting a sound that mimics an actual handwriting operation of the portable terminal.
