Multimode input

Multi-mode input provides a hot spot listening interface through which the ability to be pulled is passed.

Multimode input provides the ability to declare the priority of keystroke monitoring on the basis of the existing keystroke monitoring function, which is used for such scenarios that listen to the same key sequence and expect to be processed in sequence. At the same time, it provides an interface for returning the result of keystroke consumption, which is used to decide whether the key sequence needs to be continued to be distributed.

Multi-mode input global shortcut key registration interface, query the interface that applies the registered shortcut key function; if you need to constrain the key combination, you must use the function key as preKey

Multimode input based on touchscreen and stylus driver can simultaneously report events to the application side and distribute touchscreen and stylus events to the application side.

Joystick and game controller devices are connected to the system according to linux input and HDF input framework. After receiving the driving event, the multi-mode input converts and distributes the event according to the event conversion rules defined by the UX platform.

The multimode input obtains the input events of the hardware device through the unified HDI interface provided by the driver, and the multimode input removes the external dependence such as linux input and mtdev to ensure the original function is normal.

Multi-mode input keystroke interception, monitoring, and distribution framework optimization. The currently provided combination key registration interface inputConsumer requires a new combination key consumption return value, which is used for multi-mode input to handle multi-party monitoring and distribution scenarios.

Barrier free characteristic

Accessibility framework optimization, window and node information caching mechanism to improve the performance of extended service queries and support multi-fingered interactive gestures

Accessibility shortcut keys can support the configuration of multiple auxiliary functions at the same time. When triggered, the user selects the auxiliary functions to be turned on / off, and provides color reversal settings, screen touch, and screen magnification.

OpenHarmony version 4.1 will provide users with a more efficient, secure and comprehensive operating system experience to meet the needs of different scenarios.

The basic capability of OpenHarmony 5.0 is designed to further improve system performance, enhance the safety base and expand the distributed base function. In this release, we focus on optimizing the development framework, strengthening the basic platform functions, improving the Ark compilation runtime, and enhancing the driver framework and power management.
