Solution Overview

Problem

Electronic devices with touch screens face challenges when there is no more content to display, as users need to intuitively recognize and execute subsequent functions without additional input.

Innovation Solution

The device displays an edge of the layout corresponding to user input, followed by a first visual effect indicating no more content, and a second visual effect showing a changing UI object for a predetermined period, ultimately executing the subsequent function.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the electronic device displays content and waits for user input to execute functions, then the device operates efficiently with minimal resource usage, but the user experience deteriorates when there is no more content to display as users cannot intuitively recognize or execute subsequent functions

Engineering Contradiction:
Improveuser operation intuitivenessVSAvoidcontent display completeness
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent applies preliminary action by displaying visual effects (edge indication and UI object changes) before the user actually needs to execute the next function. When content reaches the display boundary, the system proactively shows edge indicators and transforming UI objects that preview available functions, allowing users to understand and prepare for next actions without needing to guess or search for options.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent utilizes color changes and visual transformations as UI objects transition between states. The UI object changes its appearance (color, shape, or other visual properties) during the transformation period to indicate different functional states, making it intuitively clear to users what functions are available and what will happen upon interaction.

Inventive Principle:
Principle #32Color changes

2Speed

If the electronic device provides immediate feedback for user input, then the responsiveness improves, but the complexity of the interface increases with multiple visual effects and transformation sequences

Engineering Contradiction:
Improvesystem responsivenessVSAvoidinterface complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The patent segments the feedback process into distinct phases: edge indication phase, UI object transformation phase, and function execution phase. Each phase has its own visual effect and timing, breaking down the complex interaction into manageable, sequential steps that are easier to process and implement while maintaining high responsiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs periodic action through the predetermined transformation period of the UI object. The UI object transforms over a specific time interval, creating a rhythmic, predictable feedback pattern that informs users about the system's state and upcoming actions, making the interface feel responsive and controlled rather than chaotic or overly complex.

Inventive Principle:
Principle #19Periodic action

AI summary

An electronic device and a method of executing a function of an electronic device are provided. The method includes displaying a portion of a layout containing at least one content and a user interface (UI) object corresponding to at least one function of the electronic device through a touch screen, detecting a user input through the touch screen while a portion of the layout is being displayed, displaying an edge of the layout corresponding to the movement direction of the user input in response to the user input, as the user input is continuously detected while the edge of the layout is being displayed, displaying a first visual effect and displaying a second visual effect, and displaying an execution screen of the at least one function if the predetermined period of time has elapsed.
