Abstract : HUD is a visual media technology in which 3D virtual objects are integrated into the real world in less intrusive way. It can provide information about the status and location of the surrounding environment in real time. This paper proposes an AR-HUD system to visualize the “out-of-the-window” scene and spatially align the real and superimposed objects i.e. collimation in accordance with the user’s line of sight. This is achieved through mapping the frames of references of the real site and the HUD system. The interaction between the HUD and the user is provided using an optimized head tracking approach. Observation of the people and vehicle movements in the outside world is dynamically represented in our AR HUD system. The system is further enhanced with the use of transparent projection screen with varying voltage regulation capability to adjust the transparency of the screen for observing distant objects. To evaluate the feasibility of this system, we have considered a construction site scenario which is populated with buildings, equipments, workers, and vehicles. Preliminary evaluation of the initial field tests quantify the performance of our system, compared with the real far view.
