Mixed Reality Display Control for Head-Compensated Target Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mixed reality environments, the 0-degree-of-freedom display mode leads to a poor user experience due to display information not being fixed, causing it to rotate and move with the user's head, making it difficult to maintain focus and leading to potential dizziness.
Innovation Solution
A display control method and apparatus that communicatively connect a display unit to a processing unit, allowing the user to view a real environment. The method includes displaying a user interface with an image of the real environment and target information, and controlling the target information to rotate relative to the user's head in the opposite direction of the head's rotation, ensuring the target information remains within the user's field of vision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display information is displayed in 0-degree-of-freedom mode, then the display information can be displayed in the extended reality world, but the display information rotates and moves with the user's head, causing poor user experience
Solution Approach 1:
The patent applies dynamics by making the display information dynamically adjust its position and orientation based on head rotation detection. The system transitions from a static 0-degree-of-freedom display to a dynamic display that compensates for head movements, allowing the display information to remain stable relative to the user while the head rotates. This is achieved by detecting head rotation angle and applying opposite rotation to the display information, creating a dynamic compensation mechanism that resolves the contradiction between display flexibility and user experience.
Solution Approach 2:
The patent implements feedback by continuously monitoring head rotation and using this information to adjust the display information accordingly. The system detects the rotation angle of the head and applies a compensating rotation to the display information in the opposite direction. This closed-loop feedback mechanism ensures that the display information remains stable and does not rotate with the head, thereby improving user experience while maintaining display adaptability.
2Adaptability or versatility
If display information is not fixed in the extended reality world, then the display can adapt to head movement, but the display information becomes difficult to focus on and may cause dizziness
Solution Approach 1:
The patent applies preliminary anti-action by detecting head rotation and applying an opposite rotation to the display information before the user can experience disorientation. The system anticipates the instability caused by head movement and preemptively compensates by rotating the display information in the opposite direction. This preliminary counter-action prevents focus instability and dizziness before they occur, maintaining reliability while preserving adaptability.
Solution Approach 2:
The patent uses feedback to continuously monitor head movement and adjust display information in real-time. By detecting the rotation angle and applying compensating rotation, the system maintains stable focus on display information even when the head moves. This feedback mechanism ensures that the display information remains reliably focused while adapting to head movement, preventing dizziness and maintaining user comfort.
3Adaptability or versatility
If the target information rotates with the head, then the display information follows head movement, but the target information may be obstructed by the head movement itself
Solution Approach 1:
The patent applies the inversion principle by rotating the display information in the opposite direction to the head rotation. Instead of allowing the display information to follow head movement in the same direction, the system inverts the rotation direction. This opposite rotation compensates for the head's movement and prevents the target information from being obstructed by the head, maintaining visibility while preserving adaptability to head movement.
Solution Approach 2:
The patent uses feedback to detect head rotation and apply compensating rotation to the display information. By continuously monitoring head movement and adjusting the display information in the opposite direction, the system prevents obstruction of target information. The feedback mechanism ensures that the display information remains visible and is not blocked by head movement, resolving the contradiction between adaptability and obstruction prevention.
