Touch Screen Content Fixing for Multi-Window Comparison

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users face difficulties in comparing multiple contents on a user terminal due to restricted screen size and the need to activate multiple windows, making it hard to selectively fix and compare desired content areas.

Innovation Solution

A method and device for controlling contents on a touch screen that allows users to fix specific content areas by detecting touch positions, keeping the touch state during content conversion, and converting other areas using touch gestures, enabling easy comparison of multiple contents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple windows are activated to compare contents, then content comparison capability is improved, but device complexity and ease of operation deteriorate due to needing to manage multiple separate windows

Engineering Contradiction:

Improvecontent comparison capabilityVSAvoidwindow management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple content display functions into a single window by allowing a first content to occupy a predetermined area while a second content simultaneously occupies the remaining area of the same window, eliminating the need for separate window management

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the single window into multiple display areas, where different contents can be displayed in different regions (e.g., first content in a predetermined area, second content in the remaining area), enabling content comparison without requiring multiple windows

Inventive Principle:

Principle #1Segmentation

2Area of stationary object

If the screen size is increased to display multiple contents, then content display capacity is improved, but device portability and compactness worsen

Engineering Contradiction:

Improvecontent display areaVSAvoidportability

Core Design Contradiction:

Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The patent utilizes the spatial dimension of the existing screen by allowing overlapping or adjacent display areas within the same window, effectively increasing the usable display area without physically enlarging the device

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Speed

If all contents are converted simultaneously, then content update speed is improved, but the ability to reference fixed content during conversion deteriorates

Engineering Contradiction:

Improvecontent conversion speedVSAvoidcontent reference capability

Core Design Contradiction:

SpeedVSEase of operation

Solution Approach 1:

The patent establishes a predetermined area for the first content before the second content is displayed, creating a stable reference region that exists in advance and remains fixed during the content conversion process

Inventive Principle:

Principle #10Preliminary action

AI summary

The present invention provides a method and a device for controlling contents of a user terminal having a touch screen, a recording medium therefor, and a user terminal having the same. The present invention relates to a method for controlling the contents of a user terminal having a touch screen, wherein, when a touch is detected on the touch screen while executing contents conversion, a part of the contents gets fixed on the basis of the detected location of the touch. Therefore, two or more contents can be easily compared using the fixed contents region as reference contents.
