Solution Overview

Problem

Existing electronic devices with large-sized touch screens lack diversity in single-hand operation methods, making it difficult for users to efficiently interact with the device due to the size of the screen.

Innovation Solution

A device control method that performs a zoom-out process on display content, determines a target region accessible in single-hand mode, and simulates a click action on the last touch position, allowing for single-hand operation by scaling down content to a region that can be reached by the user's thumb.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the touch screen size is increased to provide better display, then the display area is improved, but the ease of operation in single-hand mode deteriorates

Engineering Contradiction:
Improvedisplay areaVSAvoidsingle-hand operation
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the display content scalable and repositionable. The system dynamically adjusts the size and position of content based on user interaction (pinch gesture), transforming from a static full-screen display to a dynamic windowed display that adapts to single-hand operation needs while maintaining large-screen real estate.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the full-screen display into a smaller target region within the single-hand operation area. By extracting and positioning content within this accessible region, users can interact with what was previously distributed across the entire large screen using only one hand.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If traditional multi-step operations are used for activation and clicking, then the operation precision is improved, but the productivity deteriorates

Engineering Contradiction:
Improveoperation precisionVSAvoidoperation efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent merges the activation and clicking operations into a single continuous gesture. Instead of requiring separate actions (activate mode, then click), the system combines both functions into one pinch gesture that simultaneously activates single-hand mode and triggers the click at the gesture's endpoint, reducing steps while maintaining precision through gesture trajectory analysis.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system performs preliminary action by continuously tracking the gesture trajectory and pre-calculating the target position during the drag phase. This allows the system to be ready to execute the click immediately when the gesture ends, eliminating delays between gesture completion and action execution.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If continuous touch operations are required for all interactions, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improveoperation convenienceVSAvoidoperation mode complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements periodic action by allowing users to switch between full-screen mode and single-hand mode through repeated activation of the same pinch gesture. The system periodically toggles between these two operational states, providing consistent and predictable behavior that reduces complexity despite offering multiple interaction modes.

Inventive Principle:
Principle #19Periodic action

AI summary

A device control method, a non-transitory computer-readable storage medium, and an electronic device are provided. The method includes: determining a target region in a touch display screen; displaying, in the target region, the first display content subject to a zoom-out process, the target region being a region that is accessible in a single-hand operation mode; obtaining, in response to monitoring an event of switching from receiving a continuous touch operation to exiting the touch operation in the target region, a first touch position corresponding to the last touch operation before exiting the touch operation, the continuous touch operation being a touch operation having a continuous touch trajectory; and performing a simulated click action on a content displayed at the first touch position corresponding to the last touch operation.
