Solution Overview

Problem

On curved screens, electronic devices struggle to accurately detect user inputs when selecting text content near the screen edge, leading to poor integrity and accuracy of text selection and a degraded human-computer interaction experience.

Innovation Solution

A method and apparatus that involves displaying a target information input box for key information entry, followed by showing sequence number identifiers corresponding to detected text content, allowing users to select required text content by inputting sequence number identifiers without sliding on the screen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional text selection method is used on curved screen, then text selection operation can be performed, but text selection integrity and accuracy deteriorates when text is located at screen edge

Engineering Contradiction:
Improvetext selection accuracyVSAvoidtext selection operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent segments the text selection process into distinct phases: initial selection phase where user performs sliding input to select text, and confirmation phase where system presents sequence number identifiers for precise selection. This segmentation allows the system to handle curved screen detection limitations by breaking down the continuous selection process into discrete, manageable steps with clear transition points.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary detection of user input on curved screens before final text selection is confirmed. By detecting sliding input events and determining their validity in advance (presenting sequence number identifiers as confirmation), the system proactively addresses potential selection inaccuracies caused by curved screen geometry, allowing users to correct unintended selections before they are finalized.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If user slides finger from main screen area to curved surface part, then text selection can be attempted, but input detection completeness deteriorates causing selection integrity to worsen

Engineering Contradiction:
Improvetext selection integrityVSAvoidinput detection completeness
Core Design Contradiction:
ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent implements feedback by presenting sequence number identifiers to the user after detecting sliding input on a curved screen. This feedback mechanism allows the system to communicate detected input events to the user and confirm whether the intended text selection is accurate. Users can verify the selection through the presented identifiers and provide corrective input if the detection was incomplete or inaccurate due to curved screen geometry.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The sequence number identifiers serve as an intermediary between the user's sliding input and the final text selection. Rather than directly mapping finger movement to text selection boundaries (which fails on curved screens), the system introduces this intermediate confirmation step that bridges the gap between imprecise curved screen input detection and accurate text selection, allowing users to mediate and correct the selection process.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If traditional sliding selection is used on curved screen, then text selection operation can be performed, but selection accuracy deteriorates at screen edge

Engineering Contradiction:
Improvetext selection accuracyVSAvoidtext selection integrity
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The system performs preliminary detection and validation of text selection intent before finalizing the selection. By detecting sliding input events and presenting sequence number identifiers for confirmation, the system proactively identifies and corrects potential selection inaccuracies caused by curved screen geometry, ensuring both accuracy and integrity of the final text selection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by presenting sequence number identifiers to the user after detecting sliding input on a curved screen. This feedback mechanism allows the system to communicate detected input events to the user and confirm whether the intended text selection is accurate, thereby ensuring both measurement precision and reliability of the selection process.

Inventive Principle:

AI summary

This application discloses a text content selection method and apparatus, where the method includes: receiving a first input of a user for target text in a first interface; in response to the first input, displaying a target information input box on the first interface, where the target information input box is used for the user to input key information; receiving a second input of the user, where the second input is an input of the user for at least one piece of key information in the target information input box; in response to the second input, displaying N sequence number identifiers on N pieces of content, where the N pieces of content are pieces of content corresponding to the at least one piece of key information in the target text, the N pieces of content are in a one-to-one correspondence with the N sequence number identifiers, and N is a positive integer; receiving a third input of the user for M sequence number identifiers among the N sequence number identifiers, where M is a positive integer less than or equal to N; and in response to the third input, selecting, from the target text, and marking target content based on pieces of content corresponding to the M sequence number identifiers.
