Solution Overview

Problem

Users face challenges in effectively operating large-screen terminal devices with one hand, as scaling down the display area compromises user experience and navigating the screen remains inconvenient.

Innovation Solution

An operation method and electronic device that utilizes a first interface with a first window displaying first content, allowing for operations like slide up, double-tap, and slide to facilitate content synchronization and adjustment within the window, enhancing user interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display area is scaled down to facilitate one-hand operation, then ease of operation is improved, but user experience deteriorates due to poor display quality

Engineering Contradiction:

Improveone-hand operationVSAvoiddisplay area

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The display area is segmented into a first area (original content display) and a second area (scaled content display). This allows the screen to simultaneously present both the full-size interface and the one-hand optimized interface, enabling users to choose the appropriate view without compromising either display quality or ease of operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a new spatial dimension by adding a second display area that overlays or coexists with the first area. This dimensional approach allows the system to provide both full-screen and scaled-down views without reducing the original display area, thus maintaining display quality while enabling one-hand operation.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If the screen width is large, then display capability is improved, but ease of operation deteriorates when dragging content downward

Engineering Contradiction:

Improvescreen widthVSAvoidcontent dragging

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The second area acts as an intermediary interface that provides a scaled-down version of the content. Users can interact with this intermediate view more easily with one hand, and the system translates these interactions into corresponding actions in the first area, thus bridging the gap between large screen capabilities and one-hand operation limitations.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

This disclosure provides an operation method. The method is applied to an electronic device, and includes: displaying a first interface, where the first interface includes first content of a first application; detecting a first operation in the first interface; displaying a first window in the first interface in response to the first operation, where a first area in the first window is used to display the first content of the first application; detecting a second operation in the first window; and in response to the second operation, displaying second content of the first application in the first area in the first window, and displaying, in the first interface, content the same as that in the first area in the first window.
