3D Thumbnail Display with Layered Category Scrolling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thumbnail display systems face difficulties in quickly and reliably selecting a desired thumbnail from a crowded screen, as thumbnails scroll rapidly and are displayed in small sizes, making it hard to identify and access content without complex operations.
Innovation Solution
A 3D thumbnail screen is designed with layers of categories in the Z-axis direction and thumbnails in the X-axis direction, featuring a category name display part and operation means for scrolling and focusing, allowing easy selection by Z-axis and X-axis direction scrolling, with automatic cycling when no input is given.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If thumbnails are arranged in a 3D space with multiple categories simultaneously displayed, then the quantity of content that can be displayed is improved, but the size of individual thumbnails decreases and identification becomes difficult
Solution Approach 1:
The display is segmented into multiple layers corresponding to different categories, with each layer containing thumbnails for a specific category. This segmentation allows the system to display many thumbnails across multiple categories while maintaining larger individual thumbnail sizes within each layer, resolving the contradiction between quantity displayed and identification accuracy.
Solution Approach 2:
The patent transitions from a traditional 2D flat display to a 3D layered display structure where categories are arranged along the Z-axis (depth direction). This dimensional change enables simultaneous display of multiple categories with sufficient thumbnail sizes by utilizing the depth dimension, thereby increasing content quantity without sacrificing thumbnail identification quality.
2Quantity of substance
If thumbnails scroll continuously to display more content, then the quantity of content accessible is improved, but the ease of selecting a specific thumbnail deteriorates
Solution Approach 1:
The patent implements dynamic scrolling behavior where thumbnails automatically scroll horizontally within their category layers, and the entire category layers can scroll vertically along the Z-axis. This dynamic movement allows continuous access to large quantities of content while maintaining ease of operation through automatic presentation and simple navigation commands.
Solution Approach 2:
The scrolling operation follows a periodic pattern where thumbnails automatically advance at regular intervals, allowing users to observe multiple thumbnails sequentially without continuous input. This periodic action improves content accessibility while reducing operational complexity, as users only need to initiate scrolling or select from periodically presented options.
3Measurement precision
If the viewpoint is brought closer to a thumbnail to enlarge it, then the measurement precision of thumbnail viewing is improved, but the device complexity increases due to viewpoint change operations
Solution Approach 1:
Instead of changing the viewpoint position in 3D space to enlarge thumbnails, the patent maintains a fixed viewpoint and achieves thumbnail enlargement by selecting a specific category layer and displaying its thumbnails in a focused manner. This approach improves thumbnail viewing clarity without adding the complexity of dynamic viewpoint adjustment mechanisms.

AI summary
In a thumbnail screen, categories and category thumbnails are disposed and displayed in the depth (Z-axis) direction and in the horizontal (X axis) direction, respectively. When focus is given by a focus to any of upper and lower category thumbnails, which are displayed on the most front side, and a category name display part, the row (layers) of the thumbnails scrolls in the horizontal direction. When the right and left direction keys of a remote controller are operated while the category name display has focus, the scroll in the depth direction is performed, thus enabling the specification of a desired category. This three-dimensionally displays the thumbnails and facilitates the operation for viewing information.
