Abstract:
An apparatus and method for reducing power consumption of a portable terminal are provided. More particularly, an apparatus and method for reducing power consumption generated in an idle state in order to solve a power consumption problem in a portable terminal are provided. The apparatus includes a state determination unit which is configured independently from an application processor for controlling applications and which wakes up when entering an idle mode to allow the application processor to sleep, and thereafter determines a state of the portable terminal, and if it is determined that the portable terminal escapes from the idle mode, allows the application processor to wake up.
Abstract:
Provided is a method and apparatus for executing a function based on a user input. The method of executing a function in an electronic device includes: sensing a user input for selecting an object in a first area; recognizing a surface pattern of an input unit used for providing a user input in a third area when the user input is sensed in the third area; and executing a related function, based on a surface pattern recognition result in the third area when the user input of the first area and the user input of the third area are associated with each other. Accordingly, a function desired by a user may be readily executed.
Abstract:
A method of providing a user interface of a portable terminal includes receiving a mode switching request into a handwriting input mode from a user during executing an application, switching into the handwriting input mode according to the mode switching request, recognizing handwritten data received from the user, converting the recognized handwritten data to data with a preset format, processing the converted data through a preset scheme and displaying a result of the processing on a touch screen.

Abstract:
Methods and apparatus are provided for controlling a mobile terminal including a touch screen supporting a multi-touch input. The method includes: determining a number of one or more points inputted as a first touch input on the touch screen; when the number is 3, determining the first touch input as a three-point input; determining a size of a largest internal angle of a triangle generated by connecting points of the three-point input on the touch screen; displaying one of a linear tool and a circular tool based on a size of the largest internal angle of the triangle; receiving a second touch input; generating a line corresponding to the second touch input by interworking with one of the linear tool and the circular tool; and displaying the generated line on the touch screen.

Abstract:
A portable terminal and a method for controlling locking and unlocking of a touch screen are provided. The method of unlocking a portable terminal includes displaying a three dimensional (3D) lock screen recognized in 3D on a screen, and determining a locking state of the portable terminal based on a spatial gesture input when the spatial gesture input is detected on the 3D lock screen.
