Abstract: An information entering method for a terminal is provided. The terminal comprises a fingerprint sensor and a motion sensor. The terminal displays an interface, which comprises an information entering box. The terminal collects a first fingerprint using the fingerprint sensor. The terminal obtains motion data of the terminal collected by the motion sensor in a first time period after the terminal determines that the first fingerprint matches a preset fingerprint. The terminal obtains information corresponding to the first fingerprint and the motion data, or obtaining information corresponding to the motion data. The terminal enters-the obtained information into the information entering box.

Abstract: A three-dimensional image displaying system includes a drive controller, a display panel, a refraction variable part, and a lens. The drive controller is configured to display a slice image of a stereoscopic object on the display panel according to a set sequence and control, according to a depth of the slice image in the stereoscopic object, refraction intensity of the refraction variable part for a light ray projected by the display panel when the slice image is displayed on the display panel. A time required for successively displaying all slice images, which are of the stereoscopic object to be imaged and are perpendicular to one visual axis, on the display panel at a time according to the set sequence is less than a time of persistence of vision. The display panel is configured to display the slice image under control of the drive controller. The lens is configured to perform imaging according to a light ray refracted by the refraction variable part.

Abstract: A tapping control method and a terminal, which relate to the communications field and can avoid frequent automatic setting of the terminal caused by an unconscious operation of a user, thereby implementing accurate operation control on the terminal and improving a capability of the terminal to interact with the user. A specific solution is as follows. The terminal detects a tapping trigger signal within a preset frequency range by using a shock sensor; after the tapping trigger signal is detected, identifies a tapping action type corresponding to the tapping trigger signal; acquires a tapping response event that matches the identified tapping action type; and executes the tapping response event. The present disclosure can be used in a process of operation control on the terminal.

Abstract: Embodiments of the present invention provide a method for controlling a system bar of a user equipment, and a user equipment. The method includes: detecting a display status of the system bar; and when the system bar is presented on the screen of the user equipment, and the presented system bar includes a hidden button, receiving a first input used to select the hidden button and input by an input unit to hide the system bar; or when the system bar is not presented on the screen of the user equipment, receiving a second input which is input by the input unit to present the system bar. In the foregoing technical solutions, by flexibly invoking or hiding a system bar integrated with various information and/or convenient buttons, the screen can be used to display content to the greatest extent, so as to improve the utilization rate of the screen.

Abstract: Embodiments of the present invention provide a method and a system for protecting a file, which belong to the field of information security. The method includes: replacing a secure file header of a file to be protected with its original file header to convert the file to be protected to a secure file; and preventing, by the secure file header of the secure file acquired by the conversion, another peripheral from performing an access operation on content of the secure file. By using this method, in a terminal device such as an Android mobile phone or a computer, without affecting normal use by a subscriber, the protection of files such as multimedia files can be realized and content of a protected secure file in a mobile phone is not allowed to be opened on another device to achieve a purpose of avoiding private information leakage and protecting personal privacy.
