Scroll-Following Advertisement Frame Switching Control

The patent divides the advertisement display into multiple separate advertisement frames (first advertisement frame, second advertisement frame, etc.) arranged vertically on the web page. Each frame can independently follow scrolling, allowing advertisements to be segmented across different spatial locations rather than competing in a single frame. This segmentation makes switching noticeable because each frame maintains its position and the viewer can perceive changes in each distinct location.

The patent transitions from a single-frame advertisement system to a multi-frame system arranged in the vertical dimension. By distributing advertisements across multiple vertical positions on the page, the system adds a spatial dimension to advertisement presentation. This dimensional expansion allows simultaneous display of multiple advertisements in different locations, making transitions more perceptible as viewers scroll through the vertical space.

The patent establishes predetermined follow-start positions for each advertisement frame before scrolling begins. These positions are set in advance based on the web page layout, so when scrolling occurs, each frame knows its designated position to follow. This preliminary configuration simplifies real-time control during scrolling, as the system only needs to maintain frames at their pre-determined positions rather than calculating dynamic positions on the fly.

The patent implements dynamic following behavior where advertisement frames automatically adjust their positions based on scrolling progression. Each frame follows scrolling dynamically after its specific follow-start position is reached, creating adaptive display behavior. This dynamic approach allows the system to respond to user scrolling actions in real-time while maintaining controlled transitions between advertisements based on predefined triggers.
