Bullet-screen Comment Multi-direction Display

The patent applies dynamics by enabling bullet-screen comments to move along multiple preset trajectories (horizontal, vertical, diagonal directions) instead of a fixed single direction. The system dynamically selects and executes different movement paths based on comment attributes, transforming the static display into a dynamic interactive experience that adapts to user engagement needs.

The patent changes the movement parameter of bullet-screen comments from a fixed single direction to multiple variable directions. By introducing trajectory type as a changeable parameter and selecting different movement paths based on comment characteristics, the system increases adaptability while managing complexity through parameterization rather than structural overengineering.

The patent segments the movement control into discrete preset trajectories (horizontal, vertical, diagonal directions) rather than implementing continuous arbitrary motion. By dividing the movement space into distinct trajectory types and assigning them to different comment categories, the system achieves display variety while keeping the control logic modular and manageable.

The patent implements a universal motion control mechanism that handles multiple movement directions through a single integrated system. The same motion control framework supports various trajectory types by selecting different preset paths, eliminating the need for separate control mechanisms for each direction and thus managing complexity while providing diverse display options.
