Terminal Device Screen Rotation Suppression via Touch Position Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal devices require permanent setting changes to temporarily suppress automatic screen image rotation, which is inconvenient for users who need to temporarily disable this feature, such as when changing from a sitting to a lying position.
Innovation Solution
A terminal device with an inclination detection unit, touched position detection unit, comparison unit, and suppression unit that compares the user's touch position before and after a change in inclination state, allowing temporary suppression of screen image rotation without altering device settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the automatic screen image rotation function is permanently suppressed by changing device settings, then the screen orientation remains stable during position changes, but the user convenience deteriorates because the setting cannot be temporarily adjusted
Solution Approach 1:
The patent applies dynamics by making the screen image rotation suppression state changeable based on user interaction. The suppression unit suppresses rotation only when the touched position remains substantially unchanged during inclination change, allowing dynamic adaptation between rotation and non-rotation states based on real-time user behavior, rather than fixed permanent settings.
Solution Approach 2:
The system enables self-service by automatically detecting user intent through touch position monitoring. The comparison unit compares touched positions before and after inclination change, and the suppression unit automatically activates suppression when the position remains substantially unchanged, eliminating the need for users to manually change device settings.
2Object-affected harmful factors
If the automatic screen image rotation function is permanently suppressed, then the inconvenience of improper screen orientation is eliminated, but the loss of time and convenience occurs when the user needs to restore rotation functionality
Solution Approach 1:
The patent applies preliminary action by detecting touch position before inclination change occurs and preparing to suppress rotation based on this pre-captured information. The comparison unit has the touched position data ready before the inclination change happens, enabling immediate suppression activation without requiring users to spend time changing settings after the problem arises.
Solution Approach 2:
The system implements feedback by continuously monitoring touch position during inclination change and using this information to control screen rotation. The comparison unit provides feedback about position changes to the suppression unit, which adjusts rotation suppression in real-time based on whether the user is holding the device at a substantially unchanged position.
3Adaptability or versatility
If the screen image rotates automatically during inclination change, then the screen orientation adapts to different holding positions, but the harmful effect occurs when the user lies on the sofa causing improper screen orientation
Solution Approach 1:
The patent applies local quality by making screen rotation suppression localized to specific user situations. The suppression unit activates rotation suppression only when the touched position remains substantially unchanged during inclination change, which specifically addresses the sofa-lying scenario while preserving normal rotation adaptability for other holding position changes.
Solution Approach 2:
The system uses dynamics to enable the screen rotation function to adapt its behavior based on real-time user interaction patterns. The comparison unit detects whether the user is holding the device at a substantially unchanged position, and the suppression unit dynamically adjusts rotation suppression accordingly, allowing the system to distinguish between intentional position changes and situations like lying on the sofa.

AI summary
An inclination detection unit detects an inclination of the terminal device. A screen image rotation unit rotates a screen image when an inclination state of the terminal device detected by the inclination detection unit becomes a predetermined state. A touched position detection unit detects a position touched by a user. A comparison unit compares the position touched by the user before the inclination state of the terminal device becomes the predetermined state and the position touched by the user when or after the inclination state of the terminal device becomes the predetermined state. A suppression unit suppresses a rotation of the screen image by the screen image rotation unit, based on a result of comparison by the comparison unit.
