Active Portable Anchor for Augmented Reality Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality systems face challenges in maintaining accuracy when the augmented reality device is positioned farther than five meters from fixed anchors, requiring excessive anchors and time-consuming programming, and are unsuitable for dynamic environments where both objects and operators move.
Innovation Solution
The implementation of active portable anchors that output their current physical position relative to an object, allowing the augmented reality device to dynamically update its model anchor position, thereby maintaining accuracy and enabling operation in dynamic environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fixed anchors are used in augmented reality systems, then the system can provide stable reference points for displaying augmented reality information, but the accuracy decreases when the device is positioned more than five meters from the anchor
Solution Approach 1:
The patent transforms fixed, static anchors into dynamic, portable anchors that can be moved and repositioned. The active portable anchor includes positioning sensors and communication modules that enable it to dynamically update its location and maintain accurate spatial relationships with the augmented reality device, resolving the accuracy degradation issue at distances exceeding five meters.
Solution Approach 2:
The active portable anchor serves as an intermediary between the augmented reality device and the environment. It actively communicates its position data to the device through wireless communication modules, enabling the device to accurately locate and orient itself relative to the anchor regardless of distance, thus maintaining measurement precision beyond the traditional five-meter limit.
2Measurement precision
If multiple fixed anchors are deployed to maintain accuracy over larger distances, then the measurement precision improves, but the device complexity and setup time increase
Solution Approach 1:
The active portable anchor is designed as a universal, multi-functional device that combines positioning sensors, communication modules, and processing capabilities in a single unit. This eliminates the need for multiple specialized fixed anchors, reducing system complexity while maintaining accuracy. The portable anchor can serve multiple purposes including location reference, spatial mapping, and device orientation.
Solution Approach 2:
The patent extracts the anchoring function from fixed environmental structures and consolidates it into a single portable device. This extraction eliminates the need for deploying multiple fixed anchors throughout the environment, reducing device complexity and setup requirements while maintaining the necessary measurement precision through the portable anchor's active positioning and communication capabilities.
3Measurement precision
If fixed anchors are programmed into the system model, then the augmented reality device can be oriented accurately, but the programming process is time-consuming
Solution Approach 1:
The active portable anchor performs self-service by automatically determining its own position through integrated sensors and communicating this information wirelessly to the augmented reality device. This eliminates the manual programming process entirely, as the anchor autonomously provides its location data, reducing setup time to minimal configuration while maintaining orientation accuracy.
Solution Approach 2:
The active portable anchor performs preliminary positioning actions before the augmented reality device needs to orient itself. The anchor continuously determines and maintains its position data in advance, so when the device queries for orientation information, the data is already prepared and available, eliminating time-consuming programming operations.
4Stability of the object's composition
If permanent fixed anchors are used, then the system provides stable reference points, but it cannot adapt to dynamic environments where objects and operators move
Solution Approach 1:
The patent replaces static fixed anchors with dynamic portable anchors that can move and adapt to changing environmental conditions. The active portable anchor continuously updates its position through sensors and communication modules, maintaining stable reference functionality while adapting to dynamic environments where objects and operators move, thus resolving the contradiction between stability and adaptability.
