AR Map Perception Inclination Adjustment for Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality (AR) navigation systems fail to effectively adjust the perceived inclination of maps on devices to match the user's physical orientation, leading to disorientation and confusion when exploring AR environments.
Innovation Solution
The method involves continuously monitoring the physical inclination of a device using sensors like image sensors and inertial measurement units, adjusting the perception inclination of the map to match the physical inclination, and maintaining a constant perception inclination when the physical inclination exceeds a threshold, ensuring that the forward direction is consistently represented on the map regardless of the device's orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the map perception inclination is adjusted to match the device's physical inclination, then the user's spatial orientation and correlation between map directions and physical movements is improved, but the system complexity increases due to continuous sensor monitoring and dynamic rendering adjustments
Solution Approach 1:
The system continuously monitors the device's physical inclination using sensors (accelerometer, gyroscope) and uses this feedback to dynamically adjust the map's perception inclination in real-time, creating a closed-loop system that maintains accurate spatial correlation between the map and the physical environment
Solution Approach 2:
The system automatically adjusts the map perception inclination based on sensor data without requiring manual user input, and autonomously maintains the semantic significance of direction by comparing forward directions in the physical environment with corresponding map directions
2Measurement precision
If the perception inclination is continuously adjusted based on physical inclination, then the directional correlation accuracy is improved, but the processing energy consumption increases
Solution Approach 1:
The system performs perception inclination adjustments at periodic intervals rather than continuously, updating the map rendering based on sampled sensor data, which reduces processing energy consumption while maintaining adequate directional correlation accuracy for navigation
3Stability of the object's composition
If the forward direction is consistently represented on the map regardless of device orientation, then the semantic significance of direction is maintained, but the map rendering complexity increases
Solution Approach 1:
The system dynamically adjusts the map's perception inclination based on the device's physical inclination to maintain the semantic significance of direction, where the forward direction on the map consistently corresponds to the forward direction in the physical environment regardless of how the user holds the device
