Augmented Reality Display Positioning for Movable Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality display systems struggle to accurately position and display AR objects when the arrangement of objects in a space changes, particularly with movable objects, leading to user discomfort due to misalignment or inappropriate placement.
Innovation Solution
An augmented reality display device equipped with a camera, distance measuring sensor, position and orientation sensor, and a controller that recognizes real objects, determines their movability, and adjusts the position of AR objects accordingly to match the current position of the real objects, ensuring proper alignment and minimizing user discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the AR object is arranged based on the initial position of a real object, then the AR object can be displayed at a fixed position initially, but the AR object becomes misaligned when the real object moves
Solution Approach 1:
The patent applies the dynamics principle by transitioning from a static AR object positioning system to a dynamic one. The controller continuously monitors the position of real objects and updates the AR object positions in real-time based on detected movements. This allows the AR objects to dynamically follow their associated real objects, maintaining positioning accuracy even when objects move, thus resolving the contradiction between initial positioning reliability and adaptability to movement.
2Device complexity
If the system treats all objects as stationary, then the system complexity is reduced, but the AR display becomes inaccurate when objects are actually movable
Solution Approach 1:
The patent applies parameter changes by introducing a movability parameter that objects can possess. The system detects whether an object is movable or stationary and adjusts its behavior accordingly. For stationary objects, the system uses simple fixed-position tracking, while for movable objects, it activates continuous position monitoring and dynamic repositioning. This selective approach maintains low system complexity for stationary objects while achieving high measurement precision for movable objects.

Function Achieved in This Case
The system effectively maintains the appropriate positioning of AR objects relative to movable objects, providing a comfortable user experience by dynamically adjusting the display based on the real-time position and movement of objects in the environment.

AI summary
An augmented reality (AR) display device includes a camera that captures a background image; a distance measuring sensor that measures a distance to a real object in the background image; a position and orientation sensor that detects the position of the camera and the shooting direction of the camera; a controller that recognizes the real object from the background image captured by the camera and associates the predetermined AR object with the recognized real object; a display displaying an image of the associated AR object; and a memory that stores data of the real object and the AR object associated with each other. The controller determines whether or not the real object is movable from the measurement result of the distance measuring sensor, and arranges the AR object according to the current position of the real object when the position of the real object associated with the AR object moves.
