Solution Overview

Problem

Conventional mobile devices lack an efficient method for users to easily select text in e-book content, especially in environments where the device may be moved or swayed, limiting user convenience and accuracy in text selection.

Innovation Solution

A mobile device with a display unit, storage unit, and controller that displays e-book content, receives anchor interactions, and determines candidate anchors to form a block enclosing selected text, allowing users to easily and accurately select text through guide items and interaction-based candidate anchor selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional text selection methods are used in mobile devices, then text selection is possible, but text selection accuracy deteriorates in dynamic environments where the device may be moved or swayed

Engineering Contradiction:
Improvetext selection accuracyVSAvoiduser convenience
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent introduces guide items as intermediary elements that appear between the user's initial touch point and the actual text selection boundaries. These guide items (candidate anchors) serve as mediators to help users accurately define selection start and end points even when the device is moving, resolving the contradiction by providing visual guidance without requiring precise manual control

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary action by displaying candidate anchor points at estimated text boundaries before the user finalizes the selection. This allows users to see potential selection boundaries in advance and adjust their input accordingly, improving accuracy in dynamic environments without sacrificing ease of use

Inventive Principle:
Principle #10Preliminary action

2Productivity

If manual text selection is required in e-book content, then text can be selected, but the operation becomes complex and time-consuming

Engineering Contradiction:
Improvetext selection efficiencyVSAvoidselection operation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system applies self-service by automatically estimating text boundaries and generating candidate anchor points based on the user's initial touch location. The system performs the complex boundary detection and candidate generation tasks automatically, while the user only needs to select from the provided options, thereby improving efficiency without increasing operational complexity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback by displaying candidate anchor points in response to user input, allowing users to see the system's estimation of text boundaries and adjust their selection accordingly. This feedback loop enables efficient text selection by guiding users through the process with visual information about potential selection boundaries

Inventive Principle:
Principle #23Feedback

AI summary

A touch device is provided that allows users to easily select text in an Electronic Book (e-book), based on a touch interaction. A method is also provided that operates an e-book function in the touch device which includes displaying e-book content, receiving an anchor interaction at a location in text of the e-book content, displaying a number of candidate anchors, based on the location where the anchor interaction is input, determining two selected candidate anchors as definite anchors, and forming a block of text in the definite anchors.
