AR Virtual Object Position Stabilization via Distance-Based Noise Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Augmented Reality (AR) systems, noise in the recognition of object positions leads to fluctuations in the display of virtual objects, causing user displeasure, especially when the virtual objects are farther from a reference point.
Innovation Solution
An information processing device and method that estimate and correct noise effects by adjusting the display of virtual objects based on their distance from a reference point, using a control unit with components like image acquisition, recognition, noise estimation, and display control to stabilize the position and posture of virtual objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the virtual object is displayed farther from the reference point to expand the display area, then the display area is increased, but the position fluctuation due to noise becomes more significant
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the display parameters (position, size, orientation) of the virtual object based on its distance from the reference point. When the virtual object is far from the reference point, the system modifies display parameters such as reducing size or adjusting position to minimize the impact of noise, thereby maintaining measurement precision while still utilizing the expanded display area effectively.
2Measurement precision
If the virtual object follows the recognized object position precisely to maintain accuracy, then the position accuracy is improved, but the user experience deteriorates due to visible fluctuations caused by noise
Solution Approach 1:
The patent implements beforehand cushioning by pre-establishing compensation mechanisms that counteract the visible fluctuations caused by noise. The system predicts or anticipates the fluctuation effects and applies compensatory adjustments to the virtual object's display parameters in advance, cushioning the user from experiencing disruptive movements while maintaining the underlying accurate position data.
Solution Approach 2:
The system employs feedback mechanisms where the display of the virtual object is continuously adjusted based on the recognized object's position and the calculated distance from the reference point. This feedback loop allows the system to maintain position accuracy while dynamically adapting the display to minimize noise-induced fluctuations, thereby improving user experience without sacrificing measurement precision.
