It looks like you're having some serious issues detecting tags in the Unity Marker demo scene. While Aruco markers can be useful for augmented reality applications, they can actually cause performance issues under certain conditions.
Here are some suggestions and thoughts:
Optimize marker detection settings. Make sure you configure your marker detection settings in Unity to optimize performance. This may include adjusting thresholds, marker sizes, or other parameters to improve detection reliability and speed.
Check lighting conditions. Inconsistent or poor lighting conditions can significantly affect marker detection. Experiment with different lighting settings to see if there is an optimal configuration that improves detection rates.
Explore alternative marker systems. While Aruco markers are popular and widely used, they may not be the best solution for every scenario. Consider exploring alternative marker systems or tracking methods that may provide better performance for your specific application.
Update your software and libraries. Make sure you are using the latest versions of Unity, Aruco and any associated libraries or plugins. Sometimes software updates include performance improvements and bug fixes that can solve problems like the ones you're experiencing.
Community support and forums. Reach out to the developer community for support and valuable information. Forums, online communities, and developer groups dedicated to Unity and AR development can offer valuable advice, troubleshooting tips, and potential solutions based on the experiences of others.
Consider customized solutions. Depending on the specific requirements of your security training module, you may need to explore custom solutions or additional developments to achieve the desired performance and functionality.
Regarding the development status of a module and whether it is still actively supported, it may be helpful to contact the developers directly or review their documentation and release notes for any updates or announcements.
I hope these suggestions help improve tag detection performance in Unity. Feel free to experiment with different approaches and seek help from the developer community to overcome these problems. Good luck with your safety training!
