Unity tutorial: AR Indoor Navigation with Vuforia Engine - Localisation & Navigation

This 2nd tutorial covers localisation and navigation with multiple Area Targets (point clouds). We created the Vuforia Area Targets via Matterportport API using a Matterport Pro2 camera and the Vuforia Area Target Creater app on iPad Pro 12.9" 2020. For navigation we use the Navigation system of Unity.

The project was my colleagues and my Bachelor of Science in Medical Informatics thesis. The prototype was implemented in the college building of the Medical Informatics study course at the Bern University of Applied Sciences. Due to the Covid-19 pandemic we could not implement it in the hospital. Our vision is to improve way finding in hospitals to support health personell at their working space and patients.
