Edge Gesture Control for Information Element Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for scrolling through long lists or documents on touchscreens require multiple movements or separate control fields, making it difficult and unintuitive to navigate to the beginning or end of information elements without losing precision or valuable display space.
Innovation Solution
A method that allows users to perform a single, intuitive swipe gesture to jump to any edge of an information element by generating control signals based on the direction and speed of the motion, enabling direct navigation to the top, bottom, left, or right edge of the information element, without the need for multiple actions or separate control fields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple movements or separate control fields are used for scrolling, then navigation to beginning or end of information element is achieved, but display space is lost and operation complexity increases
Solution Approach 1:
The patent merges the information display area with the control input area by enabling edge-based gestures directly on the displayed content. The control functionality is integrated into the display itself, eliminating the need for separate control fields or scrollbars that would consume additional display space.
Solution Approach 2:
The patent introduces a new dimension for control by utilizing the spatial edges of the display area as control zones. Instead of adding control elements within the existing 2D display space, the solution extends control functionality to the boundaries/edges of the display, effectively using the perimeter space for control purposes without reducing the central information display area.
2Measurement precision
If multiple movements are used for scrolling, then navigation precision is maintained, but operation time and complexity increase
Solution Approach 1:
The patent implements preliminary action by detecting when the user's gesture reaches the edge of the information element and automatically completing the navigation to the target edge (beginning or end). This eliminates the need for users to perform multiple incremental scrolling actions, as the system anticipates the user's intent upon reaching the edge and completes the navigation automatically.
Solution Approach 2:
The patent enables skipping by allowing users to jump directly to the beginning or end of an information element through a single edge-reaching gesture. Instead of requiring sequential scrolling through intermediate content, the system permits direct navigation by detecting the edge gesture and immediately transporting the view to the target location, significantly reducing navigation time.
3Ease of operation
If separate control fields are provided for scrolling, then navigation control is simplified, but valuable display space is consumed
Solution Approach 1:
The patent merges the information display area with the control input area by enabling edge-based gestures directly on the displayed content. The control functionality is integrated into the display itself, eliminating the need for separate control fields or scrollbars that would consume additional display space.
4Ease of operation
If traditional swipe gestures are used for scrolling, then operation simplicity is maintained, but navigation to extreme edges becomes inefficient
Solution Approach 1:
The patent implements preliminary action by detecting when the user's gesture reaches the edge of the information element and automatically completing the navigation to the target edge (beginning or end). This eliminates the need for users to perform multiple incremental scrolling actions, as the system anticipates the user's intent upon reaching the edge and completes the navigation automatically.

AI summary
A device and a method for controlling a display device such that a section of an information element presented on the display device, where a first edge is not presented and a first edge section is presented that includes the first edge of the information element as well as the region of the information element that is adjacent to the first edge. A translation of the presented section of the information element in a first direction can be actuated via a control motion.
