3 results about "Keyboard layout" patented technology

The application relates to the technical field of system input methods, in particular to a dynamic adaptation method and device for an Android system input method, equipment and a storage medium. The method comprises the following steps: in response to a keyboard initialization request, the screen width pixels of a target display screen are acquired, the current keyboard width is determined according to the screen width pixels, and the keyboard visual area is constructed based on the current keyboard width; the keyboard layout is acquired, the layout frame boundary of the window where the keyboard layout is located is acquired, the keyboard interaction area matched with the position of the keyboard visual area is created based on the layout frame boundary; a drag view container is encapsulated in the outer layer of the keyboard layout, and a sliding event listener is added to the drag view container; the sliding offset is acquired in response to the sliding event, the position of the drag view container is adjusted according to the sliding offset, and the keyboard visual area is updated; and the updated keyboard visual area is used to keep the position of the keyboard interaction area and the keyboard visual area synchronous. The application can improve the input efficiency and operation comfort in a large-screen scene.

This invention discloses a method and system for eight-directional gliding Chinese input based on a novel keyboard layout, belonging to the field of human-computer interaction technology for touchscreen devices. Addressing the problems of existing gliding input methods, such as accidental touches during long-distance gliding, inconsistent input, inability to input uppercase letters and tones, and some keys easily sliding off the screen, this invention adopts an innovative matrix-style initial consonant keyboard layout. Through a dynamic initial-final mapping algorithm, gliding determination relies solely on directional changes, unaffected by path length. Simultaneously, dedicated keys are added and their layout optimized to enable uppercase letters and tones input, preventing keys from exceeding the screen and becoming unusable. The system collects the gliding trajectory, performs error correction, matches finals, verifies pinyin, and displays candidate words to complete the input. This invention offers simple and smooth operation, significantly improved input efficiency, greatly reduced accidental touch rate, and stronger error tolerance, making it suitable for efficient Chinese input on touchscreen devices such as mobile phones and tablets.
