Pen Posture-Based Screen Rotation Without Device Tilting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices require the user to temporarily tilt the device to initiate automatic screen rotation, which impairs usability.
Innovation Solution
An electronic device with a pen sensor that detects the position and posture of an electronic pen, calculating a rotation angle based on detection information and reference information to automatically rotate displayed objects without tilting the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the electronic device is tilted to initiate automatic rotation, then the rotation function can be activated, but the usability of the device is impaired
Solution Approach 1:
The patent replaces the mechanical tilt-detection mechanism with an electronic pen-based detection system. Instead of using sensors to detect device tilting, the system uses a pen sensor to detect the position and posture of an electronic pen, thereby triggering rotation automatically without requiring the user to physically tilt the device.
Solution Approach 2:
The patent introduces an electronic pen as an intermediary tool between the user and the device. The pen serves as a mediator to convey user intent for rotation without requiring direct manipulation of the device itself. The pen's position and posture detection acts as an intermediary mechanism to trigger the rotation function.
2Ease of operation
If the electronic device maintains horizontal placement, then usability is maintained, but automatic rotation cannot be performed
Solution Approach 1:
The patent substitutes the traditional horizontal-tilt detection mechanism with an electronic pen-based system. The pen sensor detects pen position and posture regardless of device orientation, enabling automatic rotation to function while the device remains in a fixed horizontal position, thus maintaining usability.
Solution Approach 2:
The patent introduces dynamic detection of pen position and posture that can trigger rotation in various directions (horizontal and vertical) without requiring the device itself to be tilted. The system dynamically responds to pen orientation changes while maintaining the device in a stable horizontal state.
3Manufacturing precision
If pen position and posture are detected, then accurate rotation angles can be calculated, but the device complexity increases
Solution Approach 1:
The patent makes the electronic pen serve multiple functions: it acts as both an input device for user interaction and as a sensing mechanism for detecting position and posture to trigger rotation. This multi-functionality reduces the need for separate dedicated sensors, thereby limiting the increase in device complexity while achieving accurate rotation.

AI summary
An electronic device includes a display panel that displays a displayed object, and a pen sensor provided to overlap a display area of the display panel and configured to detect a position and a posture of the electronic pen. The electronic device includes a calculation processor that calculates a rotation angle of the displayed object displayed on the display panel on a basis of detection information indicating a state related to the posture of the electronic pen detected by the pen sensor and on a basis of reference information indicating a reference state related to the posture of the electronic pen. The electronic device includes a display controller that controls display of the display panel to rotate the displayed object by the rotation angle calculated by the calculation processor.
