Abstract: A method for offering services according to facial expressions is provided. The method has an electronic device storing a service database recording at least one user's information. The method activates an offering service function; captures facial expressions of the user; extracting the features of the facial expressions; compares the extracted features with the features in images of the facial expressions stored in the service database, so as to identify a corresponding feature stored in the service database, and determines the type of expression and the service corresponding thereto from images of the user stored in the service database; and activates and provides the determined service. An electronic device using the method is also provided.

Abstract: An electronic reading apparatus comprises an input unit receiving input operations, a detect unit detecting and capturing images reflected by the input unit and a processing unit configured to receive the images to generate interruption signals; determine whether the number of the interruption signals reaches a pre-determined value in a pre-determined time; calculate a movement direction and a distance of the object on the input unit if the number of the interruption signals reaches the pre-determined value in the pre-determined time; determine a cursor displacement on the display unit and display a movement track of the cursor on a display unit. An input method for previewing files is also provided.
