Hovering Input Priority Processing for Touch Panel Pointer Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with touch panels often incorrectly sense multiple hovering inputs, leading to an undesired pointer position on the screen due to user hand or finger grip, causing user selection difficulties.
Innovation Solution
An electronic device method that detects and analyzes the priority of hovering inputs based on their location and movement path, determining the position of the hovering pointer from the input with the highest priority, distinguishing between inputs from the sensing region, bezel region, and boundary to accurately place the pointer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the touch panel recognizes hovering inputs from multiple sources (user hand or finger grip), then the sensing capability is improved, but the pointer position accuracy deteriorates
Solution Approach 1:
The patent segments the sensing area into multiple regions (sensing region, bezel region, and boundary) and assigns different priorities to hovering inputs detected in each region. This segmentation allows the system to distinguish between intentional user inputs and spurious signals from hand grip, resolving the contradiction by spatially differentiating input sources while maintaining comprehensive sensing coverage.
2Productivity
If the device processes all sensed hovering inputs equally, then the response comprehensiveness is improved, but the user selection accuracy deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-defining priority levels for different sensing regions before actual input processing occurs. When multiple hovering inputs are detected, the system immediately applies the predetermined priority scheme to identify the most likely intentional input, enabling fast processing without compromising selection accuracy through equal treatment of all inputs.
