Dynamic Video Thumbnail Scrolling and Perspective Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User interface designers face challenges in effectively presenting video content in a manner that is engaging and informative, particularly in displaying video thumbnails on video hosting sites and embedded players.
Innovation Solution
A system that generates key frames from uploaded videos to create thumbnails, which are displayed in a user interface that allows interaction, featuring horizontal or vertical alignment, scrolling effects, and mouse-over enhancements, with thumbnails rolling in and out of view to replace each other, creating a dynamic and attention-catching presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional static video thumbnail displays are used, then the implementation is simple, but user engagement and attention are reduced
Solution Approach 1:
The patent implements dynamic thumbnail displays that automatically scroll, pan, and zoom to create an engaging viewing experience. Thumbnails transition between different states (scrolling horizontally, panning vertically, zooming in/out) to maintain user attention while keeping the underlying data structure simple and manageable.
Solution Approach 2:
The system employs periodic scrolling and panning actions where thumbnails automatically cycle through display states. The thumbnails scroll horizontally for a duration, then pan vertically, then zoom, creating a rhythmic pattern that engages users without requiring complex real-time processing.
2Loss of information
If multiple video thumbnails are displayed simultaneously, then content discovery is improved, but the display space requirements increase
Solution Approach 1:
The patent utilizes multiple spatial dimensions for thumbnail arrangement - horizontal scrolling for primary navigation, vertical panning for secondary access, and zoom levels for detail viewing. This multi-dimensional approach allows many thumbnails to be accessible within a limited two-dimensional display area by navigating through different spatial layers.
Solution Approach 2:
The thumbnail collection is segmented into multiple groups that can be independently scrolled and displayed. Instead of showing all thumbnails at once, the system divides them into manageable segments that are cycled through sequentially, allowing comprehensive content display while maintaining a compact visual footprint.
3Ease of operation
If dynamic scrolling and animation effects are added to thumbnails, then user attention is captured, but the processing requirements increase
Solution Approach 1:
The dynamic effects are implemented as periodic, pre-programmed sequences rather than continuous real-time processing. Thumbnails scroll horizontally for a set duration, then pan vertically for another set duration, then zoom for a third duration, creating energy-efficient periodic cycles that engage users without sustained high processing demands.
Solution Approach 2:
The system uses CSS transforms and transitions to create visual effects that are computationally lightweight. Rather than generating new image data for each animation frame, the system applies transformation matrices to existing thumbnail images, significantly reducing processing energy while maintaining engaging visual dynamics.
Data Source
AI summary
Video thumbnails are presented on the web page of a video hosting site, or an embedded player, or a client device. Uploaded videos are examined by a thumbnail generator, which generates thumbnails from each. A presentation engine displays the generated thumbnails, which allows interaction by the user of the client. Thumbnails are displayed at rest, in horizontal or vertical alignment. Arrows or other selectors are displayed in one embodiment, and when selected cause the displayed thumbnails to appear to move in the appropriate direction, with new video thumbnails appearing on one end to replace those that travel off-screen. In one embodiment, video thumbnails appear to roll on to and off of the display using a perspective view. In one embodiment, moving a selecting device over one of the video thumbnails causes it to be accentuated, for example by appearing to move toward the viewer and appearing to increase in size.
