Abstract: A method for smart icon selection of a graphical user interface which is adapted to an electronic device displaying a plurality of icons on a screen. Each of the icons is corresponding to an application program. The method includes: detecting a movement of a cursor when the location of the cursor is not located over any of the icons; selecting an icon among the icons based on an algorithm; and generating a noticeable indicator to the selected icon. The algorithm is in accordance with parameters of the execution times of each of the application programs respectively corresponding to each of the icons, the distance between the locations of the cursor and each of the icons, the moving tendency of the cursor, and an icon corresponding to an application program being preset by a user.

Abstract: A method for composing an authentication password associated with an electronic device is implemented by a password composing system including a display, a receiving unit, and a processing unit. In the method, the display is configured to display a start point, and a plurality of displayed paths. The receiving unit is configured to detect a set of user-input movements of a contact point at the display. The processing unit is configured to determine whether the user-input movements conform with a predefined valid user-input gesture, store a plurality of codes corresponding to the valid user-input gestures, and to compose the authentication password according to valid ones of the series of the user-input movements.
