AR Orientation Cues Using Image Sensors and Map Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems in devices like smartphones and smartwatches struggle to accurately determine the user's orientation without user movement, leading to potential travel in the wrong direction until the device orients itself.
Innovation Solution
A system utilizing one or more processors to determine a user device's location within a discrete area, identify non-visible and visible orientation cues, and provide an output indicating the device's orientation, without requiring user movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the device waits for user movement to determine orientation, then the orientation accuracy is improved, but the response time and navigation efficiency deteriorate
Solution Approach 1:
The system performs preliminary actions by using image sensors to capture and analyze the environment before the user actually moves. It pre-determines orientation cues from visible objects and pre-calculates the device orientation, so that when movement occurs, the orientation is already known and can be immediately displayed without waiting for motion to trigger the measurement.
2Measurement precision
If the device requires user movement to orient itself, then the orientation determination becomes possible, but the ease of operation deteriorates as users may travel in the wrong direction
Solution Approach 1:
The device performs self-service by automatically capturing images with its sensors, automatically identifying visible objects and orientation cues, and automatically calculating its orientation without requiring any user action. The system serves itself to determine orientation, eliminating the need for users to move the device or provide input to initiate the orientation process.
3Device complexity
If the device uses only visible objects for orientation cues, then the system complexity is reduced, but the reliability of orientation determination deteriorates in environments with limited visible landmarks
Solution Approach 1:
The system achieves universality by using the same image sensor to serve multiple functions: capturing visible objects for traditional orientation cues, and simultaneously capturing environmental features that can serve as orientation references even when not clearly visible or when the user is stationary. This multi-functional use of the sensor system maintains reliability across different scenarios without adding separate hardware systems.

AI summary
The present disclosure provides systems and methods for determining the orientation of a device based on visible and/or non-visible orientation cues. The orientation cues may be a geographically located objects, such as a park, body of water, monument, building, landmark, etc. The orientation cues may be visible or non-visible with respect to the location of the device. The device may use one or more image sensors to detect the visible orientation cues. Non-visible orientation cues may be associated with map data. Using the location of the orientation cue and the distance of the orientation cue to the device, the orientation of the device may be determined. The device may then provide an output indicating the orientation of the device.
