Predictive Tiling for Fast Content Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for handling gestures in application interfaces often result in a poor user experience or excessive use of drawing resources, either by pre-rendering all potentially viewable content, which overwhelms resources, or by leaving areas of the viewport blank until rendering catches up.
Innovation Solution
Predictive tiling techniques that predict and pre-render tiles of content in advance, allowing for fast manipulation without overburdening drawing resources, by determining the optimal tile size and threshold based on viewport and content sizes, and user input velocity, direction, and inertia.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If all potentially viewable content is pre-rendered, then response speed is improved, but drawing resources are overwhelmed
Solution Approach 1:
The patent segments the content into discrete tiles that can be independently rendered and managed. Instead of pre-rendering all potentially viewable content as a single large dataset, the system divides the content space into smaller tile units that can be selectively pre-rendered based on predicted user navigation, resolving the contradiction between response speed and drawing resources by managing content in manageable segments.
Solution Approach 2:
The patent applies preliminary action by pre-rendering only the tiles that are predicted to be needed based on anticipated user gestures and navigation patterns. This selective pre-rendering approach prepares content in advance for expected user actions without overwhelming resources with unnecessary pre-rendering of all possible content, thus improving response speed for predicted interactions while conserving drawing resources.
2Quantity of substance
If content is rendered on-demand without pre-rendering, then drawing resources are conserved, but user experience deteriorates due to blank areas
Solution Approach 1:
The patent uses preliminary action to pre-render tiles that are predicted to be needed for upcoming user gestures. By analyzing gesture patterns and predicting future viewport positions, the system prepares content in advance before the user actually navigates to those areas, ensuring seamless rendering without blank areas while still conserving resources by only pre-rendering predicted content rather than all possible content.
Solution Approach 2:
The patent implements dynamics by continuously adapting which tiles are pre-rendered based on real-time gesture analysis and predicted navigation patterns. The system dynamically adjusts the pre-rendering strategy according to the user's interaction patterns, gesture velocity, and direction, ensuring optimal user experience while efficiently managing drawing resources through adaptive content preparation.

AI summary
This document describes techniques and apparatuses for predictive tiling. These techniques predict tiles of content to pre-render so that an application will be ready to render content quickly in response to a user manipulation. By so doing, these techniques enable fast manipulation of content without unduly impacting drawing resources.
