Devices and methods are disclosed for generating input. In one implementation, a stylus is provided for generating writing input. The stylus includes an elongated body having a distal end, and a light source configured to project coherent light on an opposing surface adjacent the distal end. The stylus further includes at least one sensor configured to measure first reflections of the coherent light from the opposing surface while the distal end moves in contact with the opposing surface, and to measure second reflections of the coherent light from the opposing surface while the distal end moves above the opposing surface and out of contact with the opposing surface. The stylus also includes at least one processor configured to receive input from the at least one sensor and to enable determining three dimensional positions of the distal end based on the first reflections and the second reflections.

An input display device includes: a processor to execute a program; and a memory to store the program which, when executed by the processor, results in performance of steps including: receiving an input of a track by a receiving unit; generating a track image showing the track; acquiring a character string; and displaying the character string acquired in the acquiring to be superimposed on the track image. When the character string is acquired in the acquiring before the track image is generated, the displaying the character string is stood by.

This application relates to an electronic device and an inter-device screen coordination method. The method includes: A first electronic device in a screen coordination system displays a first interface that includes first content and has a first display parameter; and when projecting the first interface to a second electronic device in the screen coordination system, the first electronic device modifies a display parameter of the first interface to be the same as a display parameter of a second interface displayed on the second electronic device, so that content display styles of the two electronic devices that are cooperatively displayed on the second electronic device are consistent. According to the method in this application, content of the first electronic device that is cooperatively displayed by the second electronic device is consistent with a content display style of the second electronic device.

A display device includes a main body configured to have a display module to which a user interface is output, a bending module located at a center of a back surface of the main body, and a controller. The controller controls the bending module to change a curvature of the display module to any one of a flat mode in which the display module is flat, a first bending mode in which the display module has a first curvature, and a second bending mode in which the display module has a second curvature, wherein the second curvature is a maximum curvature of the display module. Then, the controller changes at least one of a size and a position of a display region to which the user interface is output, according to whether a mode is the flat mode, the first bending mode, or the second bending mode.

A method for adjusting a display attribute, and a related device, to make a display effect of an element on a page more prominent. The method includes obtaining a first luminance and a second luminance on a page, where the first luminance is a luminance of an element on the page, and the second luminance is a luminance of a background region in which the element is displayed; determining a first contrast ratio between the element and the background region based on the first luminance and the second luminance; and adjusting a display attribute of the element when the first contrast ratio is less than a preset contrast ratio.

A video processing system (100) comprises at least one controller (102) configured to receive a plurality of video data from a respective plurality of video data sources (106, 208). The system can assign one of a plurality of hierarchical display layers to each of the plurality of video data, and generate an output video for display, the output video comprising at least a portion of each of the plurality of video data layered according to the assigned hierarchical display layers. The plurality of hierarchical display layers is based on a respective plurality of safety/security levels defined in a safety/security standard.

A mobile terminal for automatically adjusting a text size and a related method are provided. The mobile terminal includes a display screen, a 3D camera module, a motherboard, and a processor. The mobile terminal may be a mobile phone or a tablet. The display screen is used for displaying a text according to a text size. The 3D camera module is disposed on a top of the display screen, and is used for timely capturing a 3D image information of a human face of a user. The processor is disposed on the motherboard, and is used for calculating a distance between eyes of the user and the display screen according to the 3D image information of the human face of the user, and for timely adjusting the text size of the display screen according to the distance between the eyes of the user and the display screen.
