Edge Region Touch Input Filtering for Curved Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with touch screens, especially those featuring curved or edge displays, face issues with unintended touch inputs when gripped, leading to malfunction in handling multi-touch gestures due to accidental touches in edge regions.
Innovation Solution
A touch processing method that differentiates between intended and unintended touch events by storing initial touch inputs in specific edge regions and only processing them as valid inputs when a drag input exceeds a defined threshold, thereby reducing false triggers and enhancing user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display is extended toward the edge region to provide a curved or edge display, then the display area is increased, but unintended touch inputs occur when the user grips the device
Solution Approach 1:
The display is divided into a first region (main display area) and a second region (edge/curved display area). The system segments touch event processing by location, applying different handling rules to each region. Touch events in the second region are processed differently to prevent unintended inputs while maintaining functionality in the first region.
Solution Approach 2:
Different touch event processing rules are applied to different regions of the display. The first region uses standard touch processing, while the second region uses specialized processing that considers grip patterns and distinguishes between intentional and unintentional touches based on local characteristics.
2Adaptability or versatility
If multi-touch gesture support is added to handle two different touch points, then gesture capability is improved, but the device becomes unable to properly handle touch input when unintended touch occurs in the edge region
Solution Approach 1:
A touch event processing system acts as an intermediary between the touch screen and applications. This intermediary layer analyzes touch events, determines their origin (intentional vs. unintentional), and selectively processes or discards them before they reach the application layer, enabling reliable multi-touch handling despite edge region challenges.
Solution Approach 2:
The system uses feedback from touch event analysis to dynamically adjust processing. By analyzing the pattern, location, and characteristics of touch events, the system determines whether a touch is intentional or unintentional and adjusts its processing accordingly, maintaining reliability while supporting multi-touch gestures.
3Speed
If touch input in the edge region is immediately processed as valid input, then response speed is improved, but false triggers from gripping occur
Solution Approach 1:
The system performs preliminary analysis of touch events in the second region before processing them as valid inputs. By pre-evaluating touch characteristics, location, and patterns, the system filters out potential false triggers before they can cause incorrect actions, while still maintaining fast response for legitimate touches.
Data Source
AI summary
Methods and apparatuses for touch event processing are provided. A touch input is received in a designated region of a touchscreen display of the electronic device. The touch input is stored in a memory of the electronic device without providing the touch input as input to an application of the electronic device, upon reception of the touch input in the designated region. A drag input is received on the touch screen display as a continuation of the touch input. A processor of the electronic device determines the touch input and the drag input as input for the application upon the drag input exceeding a threshold.
