Description

Technical Field

[0002] With the rapid development of application scenarios such as remote office, industrial monitoring, intelligent interaction and distributed collaboration, remote control of multi-screen computer systems has become a key technical means to improve operational efficiency and user experience. Especially in the context of widespread deployment of high-resolution multi-screen terminals, users need to achieve seamless switching and precise control between different screens during remote control to meet the actual needs of cross-screen data interaction, task allocation and interface synchronization. Therefore, building a remote control method that supports cross-screen intelligent prediction and precise control has become a research hotspot in the field of human-computer interaction systems.

[0003] Existing multi-screen remote control methods generally rely on static screen mapping rules and fixed coordinate conversion methods, making it difficult to perceive dynamic factors such as physical differences, environmental interference, and network jitter in real time across multiple screen devices. This leads to problems such as decreased accuracy, response delays, or target misalignment in operation trajectories in cross-screen scenarios. In addition, although some solutions introduce image stream compression or frame synchronization mechanisms to improve transmission efficiency, they often lack dynamic prediction mechanisms and error pre-compensation strategies for user intentions, and are unable to achieve high-precision, low-error operation control under complex heterogeneous screen layouts.
