Vehicle Control Device for AR Glasses Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face challenges in specifying the position of AR glasses without attaching a tracking rig or marker, which increases weight and affects the balance and comfort of the glasses.
Innovation Solution
A vehicle control device that includes a storage unit for storing first feature information of AR glasses detected by a sensor and a specifying unit that checks this information against second feature information obtained from AR glasses brought into a vehicle, allowing the device to specify the position of the AR glasses without additional attachments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a tracking rig or marker is attached to the AR glasses to detect the relative position between the vehicle and the AR glasses, then the position specification accuracy is improved, but the weight of the AR glasses increases and the weight balance is lost
Solution Approach 1:
The patent extracts the tracking function from external attachments (rigs or markers) and integrates it into the AR glasses themselves through built-in sensors. This allows the system to detect the relative position between the vehicle and AR glasses without adding external weight, thereby maintaining measurement precision while eliminating the weight penalty of attached components.
Solution Approach 2:
The AR glasses perform self-tracking by using built-in sensors to detect their own position and orientation relative to the vehicle. The glasses independently determine their spatial relationship with the vehicle without requiring external tracking infrastructure, thus avoiding the need for additional weight-bearing attachments while maintaining accurate position specification.
2Measurement precision
If a tracking rig or marker is attached to the AR glasses to detect the relative position, then the position specification capability is improved, but the feeling of wearing the AR glasses is impaired
Solution Approach 1:
The tracking functionality is extracted from external attachments and embedded within the AR glasses structure. This integration eliminates the need for bulky rigs or visible markers that would interfere with the user's field of view and overall comfort, while preserving the ability to accurately specify position for AR content overlay.
Solution Approach 2:
The AR glasses independently perform position detection using internal sensors, eliminating the need for external tracking equipment that would compromise wearing comfort. The self-contained approach allows the glasses to maintain accurate spatial awareness without adding bulk or visual obstructions that would impair the user experience.

AI summary
The storage unit stores first feature point information of the AR glasses obtained by photographing the AR glasses with a camera (tracking camera or camera) and extracting features. Further, the specifying unit combines second feature point information obtained by photographing the AR glasses brought into the car with a tracking camera and extracting features with the first feature point information stored in the storage unit. The position of the AR glasses brought into the vehicle is determined based on the verification results.
