Transparent Display Virtual Info Alignment via Predictive Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transparent display technologies struggle to maintain real-time alignment of virtual information with dynamically moving physical objects, leading to discomfort and readability issues due to unpredictable movements.
Innovation Solution
An information display system comprising a light transmissive display, a first information extraction device for user spatial position, a second information extraction device for target object spatial position, and a processing device that determines and updates the display position of virtual information based on the distance between reference positions at previous and current times to ensure accurate and stable superimposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual information is displayed based on real-time object recognition, then the virtual information can follow the movement of the physical object, but the virtual information becomes shaken or stacked making it difficult to read
Solution Approach 1:
The patent applies preliminary action by predicting the future position of the physical object based on its current movement state (velocity, acceleration) before displaying the virtual information. This allows the system to pre-calculate where the object will be, rather than reacting to its current position, thereby preventing the shaking and stacking effects that occur with real-time recognition alone.
Solution Approach 2:
The patent implements dynamics by continuously updating the prediction model based on the object's changing movement state. The system adapts to variable and unpredictable movements by adjusting prediction parameters in real-time, maintaining accurate alignment despite the object's dynamic behavior.
2Speed
If the virtual information is updated in real-time, then it follows the object movement, but the unpredictable movement causes shaking or stacking of virtual information
Solution Approach 1:
By predicting future positions based on current movement states, the system maintains fast response speed while avoiding the instability caused by reacting to unpredictable real-time movements. The prediction buffer smooths out erratic movements.
Solution Approach 2:
The patent applies beforehand cushioning by using prediction algorithms to anticipate and compensate for unpredictable movements before they affect display stability. This predictive buffering prevents the shaking and stacking effects that would otherwise occur during real-time updates.
3Adaptability or versatility
If a light transmissive display is used, then the user can view the physical object and virtual information simultaneously, but the virtual information deviates from the physical object when it moves dynamically
Solution Approach 1:
The patent implements feedback by continuously monitoring the physical object's position, velocity, and acceleration, then using this information to update the prediction model and adjust the virtual information positioning accordingly. This closed-loop feedback ensures accurate alignment despite the transparency of the display.
Solution Approach 2:
The system uses dynamic prediction that adapts to the object's movement characteristics, maintaining high positioning accuracy on the transparent display regardless of how the object moves. The prediction model adjusts to variable movements in real-time.

AI summary
A method, a processing device, and a system for information display are provided, and the system includes a light transmissive display. A first information extraction device extracts spatial position information of a user, and a second information extraction device extracts spatial position information of a target object. The processing device performs the following steps. Display position information of virtual information of the target object on the display is determined according to the spatial position information of the user and the spatial position information of the target object. The display position information includes a first display reference position corresponding to a previous time and a second display reference position corresponding to a current time. An actual display position of the virtual information on the display corresponding to the current time is determined according to a distance between the first display reference position and the second display reference position. The virtual information is displayed on the display according to the actual display position.
