Touchscreen Area Segmentation for Accidental Edge Touches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals with narrow rims are prone to misjudging accidental touch operations on the edge areas, leading to unintended tasks and resource wastage due to the inability to differentiate between intentional and accidental touches.
Innovation Solution
A method and device for a mobile terminal that determines the operation area of touch operations and applies response rules based on predefined areas to differentiate between intentional and accidental touches, reducing resource wastage by prioritizing responses to intentional touches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal directly responds to all touch operations on the touch screen, then the responsiveness and user experience are improved, but the mobile terminal will mistakenly respond to accidental touches on the edge area, causing resource wastage and unintended tasks
Solution Approach 1:
The touch screen is segmented into multiple operation areas (first operation area and second operation area) with different response characteristics. The edge area is identified as a separate second operation area where accidental touches are more likely to occur, allowing the system to apply different response strategies to different regions, thereby reducing resource wastage from mistaken responses while maintaining reliability in the main operational area.
Solution Approach 2:
Different response qualities are applied to different regions of the touch screen. The first operation area (main area) receives full responsiveness, while the second operation area (edge area) receives restricted or conditional responsiveness. This local differentiation allows the system to maintain high reliability where needed while avoiding resource wastage in areas prone to accidental touches.
2Loss of energy
If the mobile terminal restricts response to touch operations in the edge area to avoid accidental touches, then resource wastage is reduced, but the responsiveness and user experience in the edge area deteriorates
Solution Approach 1:
The response behavior in the edge area is made dynamic rather than statically restricted. The system dynamically evaluates touch operations in the second operation area by comparing them with reference touch operations or analyzing touch patterns over time. This dynamic approach allows the system to maintain resource efficiency by default while still enabling legitimate edge area interactions when they match expected patterns, thus preserving ease of operation for valid gestures.
Solution Approach 2:
The system uses feedback mechanisms to distinguish between accidental and intentional touches in the edge area. By analyzing touch characteristics, duration, pressure, and patterns, the system provides appropriate feedback responses only for valid operations. This feedback-based approach reduces resource wastage from accidental touches while maintaining responsiveness for intentional user actions in the edge area.

AI summary
A method and a device for responding to a touch operation are provided, relating to the field of human-computer interaction. The method includes the following. Receive a first touch operation and a second touch operation which act on a touch screen for a preset time period (701). Determine an operation area where the first touch operation occurs, where the touch screen includes a first operation area and a second operation area, and the operation area where the first touch operation occurs is the first operation area or the second operation area (702). Determine an operation area where the second touch operation occurs, where the operation area where the second touch operation occurs is the first operation area or the second operation area (703). Determine whether to respond to at least one of the first touch operation and the second touch operation according to the operation area where the first touch operation occurs and the operation area where the second touch operation occurs (704). According to the method, the probability of responding of a mobile terminal to an accidental operation can be reduced.
