Solution Overview

Problem

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

Innovation Solution

An operation method that includes displaying a first interface with first content, detecting operations to synchronize and scale or move content within a first window, and adjusting the window's size and location to enhance user interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If software is scaled down for one-handed operation, then ease of operation is improved, but user experience deteriorates

Engineering Contradiction:
Improveone-handed operationVSAvoiduser experience
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The screen is divided into a first display area and a second display area. The first display area displays the application interface at normal size, while the second display area displays a scaled-down version of the same interface. This segmentation allows users to access both full-size and one-handed operation modes simultaneously, resolving the contradiction between ease of operation and user experience.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A virtual machine is introduced as an intermediary component that receives touch inputs from the second display area, translates them into corresponding touch events for the first display area, and sends the translated events to the application. This intermediary enables the small-screen interface to control the large-screen application, providing both one-handed operation convenience and full user experience.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Area of stationary object

If screen width is large, then display area is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvedisplay areaVSAvoidone-handed operation
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The solution adds a spatial dimension by creating a separate second display area that is spatially distinct from the first display area. The second display area can be positioned at locations convenient for one-handed operation (such as near the bottom edge of the screen), while the first display area maintains its full size for optimal visual experience. This dimensional separation allows both large display area and ease of one-handed operation to coexist.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

This application 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, so that a user can perform an operation on the content displayed in the first area in the first window, and synchronize the content with the content displayed in the first interface, to improve user experience.
