Overscroll Visual Effects for Edge Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices often have limited viewing regions, leading to user frustration when they cannot visually indicate the reach of content edges during scrolling, rotation, or scaling, as existing systems fail to provide adequate feedback.
Innovation Solution
A computer-implemented method and system that applies a stretch effect to the displayed content when an edge is reached, increasing blank space between content items based on the distance from the edge, providing visual feedback to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If content is displayed within a limited viewport, then the device can display content, but the user cannot visually indicate the reach of content edges during scrolling
Solution Approach 1:
The patent applies visual effects that change the appearance of content near edges, making them appear to stretch or distort. This visual transformation provides feedback to users about reaching content boundaries without requiring additional space in the viewport.
Solution Approach 2:
The patent implements a feedback mechanism where the display provides visual feedback (stretch effects) when the user reaches content edges during scrolling. This feedback loop informs users about content boundaries, addressing the information loss problem while maintaining the limited viewport area.
2Ease of operation
If visual feedback is provided when content edges are reached, then user experience is enhanced, but the display complexity increases
Solution Approach 1:
The patent uses dynamic visual effects that activate only when needed (when content edges are reached). The stretch effect is applied conditionally based on user interaction state, providing enhanced user experience without requiring complex display mechanisms to be always active.
Solution Approach 2:
The patent changes visual parameters (such as scaling or positioning) of content elements dynamically based on their proximity to edges. This parameter-based approach provides sophisticated feedback while maintaining relatively simple implementation through standard display operations.

AI summary
Methods for providing visual feedback when an end area of content is reached are provided. In one aspect, a method includes receiving an input in a first direction to at least one of scroll, rotate, or scale a portion of content provided for display, and determining whether an edge of the content in the first direction is reached in response to the input. The method also includes applying a stretch effect to the displayed portion of content when the determination indicates an edge of the content in the first direction is reached. Systems and machine-readable media are also provided.
