Display Orientation via Image Sensor Reference Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display orientation systems often incorrectly change due to physical orientation changes, leading to misalignment when users interact with devices like tablets, as sensors detect movement rather than intended user presence.
Innovation Solution
A display system with an image sensor that acquires electronic images and a processor controlling the display orientation based on reference images, such as body parts or objects, to align the screen with the user without physical movement, using CMOS or CCD sensors and computer vision for accurate image processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If physical orientation sensors are used to control display orientation, then the display can automatically adjust to device movement, but the display orientation becomes incorrect when physical orientation does not reflect intended user interaction
Solution Approach 1:
The patent replaces mechanical orientation sensors (accelerometers, gyroscopes) with an optical image-based detection system. The processor captures images using an image sensor, detects reference images (such as hands, faces, or objects) in the field of view, and determines display orientation based on the spatial position of these reference images rather than physical device movement. This substitution resolves the contradiction by making display orientation independent of physical orientation while maintaining automatic adaptation capability.
Solution Approach 2:
The patent introduces reference images as an intermediary between the user and the display system. Instead of directly sensing device physics, the system detects the presence and position of reference images (hands, faces, objects) in the user's interaction space. This intermediary allows the display to orient toward the user's intent rather than following device movement, improving reliability while preserving adaptability.
2Ease of operation
If the display follows physical movement, then automatic orientation control is achieved, but accidental misalignments occur during user interaction
Solution Approach 1:
The system replaces mechanical motion sensing with optical field-of-view analysis. By capturing images and detecting reference image positions, the system determines orientation based on user presence and intent rather than device physics. This maintains automatic control ease while eliminating accidental misalignments caused by unintended device movement.
Solution Approach 2:
The system implements feedback through continuous image capture and reference image detection. The processor monitors the field of view for reference images and adjusts display orientation based on detected user position. This feedback loop ensures the display responds to intentional user interaction rather than accidental movement, improving reliability while maintaining ease of operation.
