Solution Overview

Problem

Users face difficulty in selecting distant icons or hard keys on electronic devices with large-screen displays while holding the device with both hands, leading to undesirable movement and accuracy issues.

Innovation Solution

The electronic device employs a processor to display first and second user interface components, where the second UI component shows a specific image of the area where the first UI component is located, allowing users to select icons without detaching their hands by displaying the second UI component based on the location of the first input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a large-screen display is used to provide highly readable contents, then content readability is improved, but portability deteriorates and user manipulation difficulty increases

Engineering Contradiction:
Improvecontent readabilityVSAvoiduser manipulation difficulty
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The display area is segmented into a main display area and a sub-display area. The sub-display area provides a magnified or alternative view of specific content regions, allowing users to read detailed content in the sub-display while maintaining overall context in the main display. This segmentation enables effective use of the large screen without requiring users to reach across the entire display area.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a spatial dimension by adding a sub-display area that can be positioned independently from the main display. This creates a multi-layered display structure where content can be viewed at different scales and positions simultaneously, enabling users to access distant icons or content without physical hand movement.

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

2Measurement precision

If a user detaches one hand from the electronic device to select a displayed icon, then selection accuracy is improved, but device stability deteriorates

Engineering Contradiction:
Improveselection accuracyVSAvoiddevice stability
Core Design Contradiction:
Measurement precisionVSStability of the object's composition

Solution Approach 1:

The sub-display area acts as an intermediary between the user's hand and the main display content. Users can interact with the sub-display using their thumb or finger while the other hand stabilizes the device. The sub-display translates touch inputs into selections on the main display, eliminating the need to detach hands while maintaining both stability and selection accuracy.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The sub-display creates a copy or representation of specific content from the main display area. This copied view allows users to select icons or content by touching the sub-display, which then maps the selection back to the corresponding location in the main display. This copying mechanism enables accurate selection without requiring direct interaction with the distant main display area.

Inventive Principle:
Principle #26Copying

3Ease of operation

If a user detaches both hands to select hard keys, then selection capability is improved, but operational convenience deteriorates

Engineering Contradiction:
Improveselection capabilityVSAvoidoperational convenience
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The sub-display area serves multiple functions: it acts as a magnifying glass for small icons, provides alternative content views, and functions as a touch interface for selecting hard keys. This multi-functionality allows users to perform various selection tasks without detaching hands, maintaining operational convenience while improving selection capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An electronic device is provided. The electronic device includes a display for receiving a user's touch input and at least one processor electrically connected to the display. The at least one processor is configured to display, on the display in response to a first input, a first user interface (UI) component for distinguishing at least part of an entire display area of the display from the entire display area, and a second UI component for displaying a specific image of an area where the first UI component is located. The processor is further configured to determine a location of the second UI component displayed on the display, based on a location of the first input.
