17Augmented Reality System for maritime navigation

Case Study: AR-Binocular

18Navigation problem: Map adjustmentSource: [Porathe, Shepard]: 2D/3D Reprsentation of navigation maps

2D North-Up2D Head-Up 3D Egocentric 19Study (Porathe, Shepard) reveals: Comparison of map adjustment between navigation officer and Layman:Transformation (Rotation) needs time proportional to rotation angle, can not be trained, navigation officers and Layman indistinguishableNavigation officers value the intuitive use of 3D egocentric maps

Concept AR-Binocular: Direct 3D overlay of map in view with AR (3D Egocentric view)Navigation problem: Map adjustment20

Traditional: 2D Top-ViewNautic chart top view

New: 3D Egocentric view

Potential of AR for maritime Navigation+ AR holds potential for use in maritime navigation+ Map superposition in camera view feasible, head-up projection displays on bridge is an option- Systematic content production (authoring) still missing- Sensors for mobile AR expensive and still in progress+ Integration of AR on Smartphones/I-Pads in the future30Thank you very much
