Display Orientation Control via Camera Reference Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices struggle to automatically control the orientation of an image correctly when the device is positioned horizontally, leading to confusion about the image's alignment with the user.
Innovation Solution
An apparatus and method that utilize a camera and orientation sensor to capture an image of a reference feature, such as the user's face, and adjust the image display area to align with the user's perspective, using facial recognition and orientation sensors to determine the correct orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If auto rotation function is designed to function while user is standing or sitting up right, then the device can correctly display image orientation in vertical positions, but the device becomes confused and cannot correctly display image orientation when the device is horizontal to the ground
Solution Approach 1:
The system dynamically adjusts the image display orientation based on real-time detection of device position and user orientation. The computing device continuously monitors orientation sensor data and camera images, then dynamically rotates the image display area to maintain correct alignment with the user's viewing direction, whether the device is held vertically or horizontally.
Solution Approach 2:
The system implements a feedback loop where the orientation sensor and camera continuously provide information about device position and user orientation. The computing device processes this feedback and automatically adjusts the image display orientation accordingly, creating a closed-loop control system that adapts to changing conditions in real-time.
2Device complexity
If the device uses orientation sensor alone to control image display, then the system remains simple, but the device cannot correctly determine user orientation when held in unexpected positions
Solution Approach 1:
The system merges the functionality of the orientation sensor with the camera and facial recognition system. By combining these components, the device achieves more precise user orientation detection than any single component could provide alone, while maintaining reasonable system complexity through integrated processing in the computing device.
Solution Approach 2:
The computing device acts as an intermediary that processes data from the orientation sensor and camera, then synthesizes this information to determine the correct image display orientation. This intermediary processing layer allows the system to overcome the limitations of individual sensors and achieve more accurate orientation detection.

Data Source
AI summary
An electronic device includes a display with an image display area configured to change orientation based on a change of position of the device. Upon detection of the position change, a camera may capture an image adjacent the device. The orientation of the image display area may be moved relative to a reference feature captured in the image.
