AR Location Filtering for Stable Digital Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality applications on mobile devices face challenges due to unstable location detection, causing digital objects to move erratically, which disrupts the user experience and makes it difficult to accurately interact with or retrieve digital elements.
Innovation Solution
A system that filters and stabilizes the location data of mobile devices by averaging consecutive location readings and limiting the movement rate of digital objects, ensuring they remain within a predetermined area, thereby enhancing user interaction and stability in augmented reality environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If GPS location positioning technology is used to determine the location of a mobile device, then location-based capabilities such as route guidance and searching can be provided, but the location data becomes unstable and erratic due to natural and artificial errors and interferences
Solution Approach 1:
The system performs preliminary filtering of location readings before they are used for rendering digital elements. By pre-processing the GPS data through filtering operations, the system prepares stable location information in advance, preventing erratic movements of augmented reality objects before they occur.
Solution Approach 2:
The patent introduces an intermediary filtering mechanism between the GPS receiver and the augmented reality rendering system. This intermediary layer processes raw location data through filtering operations, transforming unstable GPS readings into stable location information that controls digital element positioning.
2Reliability
If consecutive location readings are filtered by averaging, then location stability improves, but the responsiveness to actual movement may be reduced
Solution Approach 1:
The filtering system dynamically adjusts its behavior based on the detected movement pattern. When movement is detected, the filter allows faster response; when stationary, it applies stronger smoothing. This dynamic adaptation resolves the contradiction between stability and responsiveness by changing filter characteristics in real-time.
Solution Approach 2:
The system changes the filtering parameters based on the state of the device. By adjusting filter strength or response time according to whether the device is moving or stationary, the system optimizes both location stability and movement responsiveness under different operating conditions.

AI summary
Improving a perception of an augmented reality object is disclosed. A new location of an observing platform is received. A filtered location of the observing platform is determined based at least in part on the new location in a manner that reduces a rate of change of a rendering location of the augmented reality object. A new relative position of the augmented reality object is calculated based at least in part on the filtered location. A display of the observing platform is updated using the new relative position.
