| Video: Inside the tech: Visual positioning as enabler of Augmented Reality | Video courtesy of NavVis YouTube Channel | 3 August 2021 Video: Visual Positioning/Tracking Enables AR Within a 3D Tour (Hint/Magic) Hi All, NavVis Co-Founder and Head of Positioning & Mobile Sebastian Hilsenbeck explains Visual Positioning/Tracking enabling Augmented Reality (AR) within a 3D Tour. Your thoughts? Best, Dan Transcript (Video above) AR or augmented reality ultimately tries to achieve a new form of user interface. And that is an interface where the real surroundings that a user perceives are overlaid with digital content that either enable the user to play games, mixing real and virtual content or to solve tasks more efficiently or safely. That is the user interface part and in order to enable that under the hood augmented reality requires a technology that's called visual tracking. And that technology understands in real time how the AR device is being moved around and rotated. And the purpose of that is to keep the reality and the virtual content precisely in sync. Visual tracking by itself only understands how the AR device is being moved around. It does not understand where in the world this is happening. So it happens kind of in a vacuum from the perspective of the visual tracking system. Visual positioning on the other hand is the technology that then relates this to a global coordinate system, so that the AR experience as a whole understands also where in the world this is happening. Without positioning an AR experience can only understand relative motion and it cannot decide for the user what virtual content is useful for the user. So the user is always the one who has to decide and place virtual content in the AR scene and the AR session can only keep it in sync. But to be truly helpful and meaningful the AR session should be able to anticipate what the user wants to accomplish. And one way of achieving this is to use visual positioning to relate the AR session with a global coordinate system. In this way be able to pull in all kinds of digital information that is relevant to the current location of the user. |

| I like this. If I was working on an aircraft, I could walk to the aircraft, go to the position for which I'm working at, and pull up all relevant information(maintenance, etc) to work on it and view the manual either on an ipad or VR. AR would make it easier to get to the information faster. Wendell |
