Solution Overview

Problem

Mobile terminals with narrow rims often mistakenly respond to touch operations on the edge areas of the touch screen, leading to unintended tasks and resource wastage, as they cannot accurately differentiate between intended and unintended touches.

Innovation Solution

A touch operation response method that determines two operation areas on the touch screen and evaluates touch operations based on their types (click, slide, long-press) and areas, prioritizing responses to reduce mistaken interactions by adapting to the user's holding mode, display mode, and current usage scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the mobile terminal directly responds to all touch operations on the touch display screen, then the response speed is fast, but the accuracy of operation recognition deteriorates due to mistaken touches on edge areas

Engineering Contradiction:
Improveresponse speedVSAvoidoperation recognition accuracy
Core Design Contradiction:
SpeedVSMeasurement precision

Solution Approach 1:

The touch display screen is segmented into multiple operation areas (first operation area, second operation area, third operation area) with different response priorities. The processor determines the operation area where the touch operation occurs and applies different response strategies to different areas, thereby improving operation recognition accuracy while maintaining fast response speed through area-specific processing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different operation areas are assigned different response priorities and characteristics. The first operation area (edge area) has lower response priority to filter mistaken touches, while the second and third operation areas have higher response priorities for intentional operations. This local differentiation resolves the contradiction by applying appropriate response speed and accuracy characteristics to different regions.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If the mobile terminal responds to all touch operations including those on edge areas, then the ease of operation is improved, but resource wastage increases due to unintended tasks

Engineering Contradiction:
Improvetouch operation convenienceVSAvoidresource consumption
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The processor performs preliminary determination of the operation area before executing the touch operation response. By pre-identifying whether a touch occurs in the first operation area (edge area) or other areas, the system can preemptively filter out potential mistaken touches, preventing unnecessary task execution and reducing resource consumption while maintaining ease of operation for legitimate touches.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from the operation area determination to control whether to respond to the touch operation. When a touch operation is detected in the first operation area, the feedback mechanism determines not to respond, thereby avoiding resource wastage. This feedback-based control maintains ease of operation by still detecting all touches while intelligently filtering responses based on location feedback.

Inventive Principle:
Principle #23Feedback

3Area of stationary object

If the mobile terminal uses narrow rims to increase screen ratio, then the display area is increased, but the probability of mistaken touch operations increases on the edge areas

Engineering Contradiction:
Improvescreen ratioVSAvoidmistaken touch probability
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The touch display screen is divided into distinct operation areas, with the first operation area specifically identifying the edge area where mistaken touches are more likely to occur. This segmentation allows the system to maintain the narrow rim design and high screen ratio while applying specialized processing to the edge area to reduce mistaken touch probability through area-based response priority adjustment.

Inventive Principle:
Principle #1Segmentation

AI summary

A touch operation response method and device in the field of human-computer interaction. The method includes: determining a first operation area and a second operation area in the touch display screen; receiving a first touch operation and a second touch operation acting on the touch display screen within a preset time period; determining an operation area on which the first touch operation acts, where the touch display screen includes the first operation area and the second operation area; determining an operation area on which the second touch operation acts; based on the operation area on which the first touch operation acts and the operation area on which the second touch operation acts, determining whether to respond to the first touch operation and/or the second touch operation.
