Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing information processing devices face inconvenience when automatically changing screen layouts based on device inclination, leading to user dissatisfaction, especially when users change postures, as it can result in unwanted changes to the screen orientation.

Innovation Solution

An information processing device equipped with an inclination detection unit and a display processing unit that generates signals to initiate or cancel changes in screen orientation, allowing users to manually control the screen layout changes through a CANCEL command, and optionally incorporates a rotation detection unit to adjust the rotation setting time based on the rotation axis or angular velocity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the screen layout is automatically changed based on device inclination detection, then the information presentation adapts to device orientation, but the user convenience deteriorates when the user wants to maintain the original screen direction

Engineering Contradiction:

Improvescreen layout adaptationVSAvoiduser convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system provides feedback to the user by displaying a preview of the rotated screen layout before the change is finalized. This allows the user to see the effect of the rotation and decide whether to confirm or cancel it, thereby maintaining user convenience while enabling screen layout adaptation.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary action by showing a preview of the screen layout rotation before actually executing the change. This preliminary display allows the user to anticipate the result and make an informed decision, preventing unwanted automatic changes while still enabling adaptive layout changes when desired.

Inventive Principle:

Principle #10Preliminary action

2Extent of automation

If the screen layout changes automatically upon device rotation, then the display orientation adapts to gravity direction, but the user loses manual control over screen orientation

Engineering Contradiction:

Improveautomatic screen rotationVSAvoidmanual control

Core Design Contradiction:

Extent of automationVSEase of operation

Solution Approach 1:

The system asks for user confirmation before executing automatic screen rotation by displaying a preview and waiting for user input. This feedback mechanism ensures that automatic changes only occur when the user intends them, preserving manual control while maintaining automation capability.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The preview display acts as an intermediary between the automatic rotation detection and the actual screen layout change. It mediates the process by allowing the user to review and approve or cancel the rotation, thus maintaining manual control over the automated process.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the screen layout is rotated to match device inclination, then information is easily readable in most positions, but unwanted rotation occurs when user posture changes

Engineering Contradiction:

Improvescreen readabilityVSAvoidunwanted screen rotation

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The system displays a preview of the rotated screen layout before executing the rotation, giving the user a chance to cancel unwanted rotations caused by posture changes. This preliminary action prevents harmful unwanted rotations while maintaining readability adaptation when desired.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The preview display provides feedback to the user about the intended rotation, allowing them to distinguish between desired rotations (for readability) and unwanted rotations (due to posture changes). This feedback mechanism eliminates unwanted rotations while preserving beneficial ones.

Inventive Principle:

Principle #23Feedback

AI summary

An information processing device is disclosed. The information processing device includes an inclination detection unit configured to generate a first signal regarding inclination of the device. The information processing device also includes a display processing unit configured to, based on the first signal, generate a second signal to initiate a change in orientation of a display of content, and generate a third signal to cancel the change in orientation in response to receipt of a CANCEL command after initiation of the change.
