Projection-based Augmented Reality in Engineering Applications

Augmented Reality (AR) superimposes computer-generated graphics onto the user's view of the real world. Today, AR applications can occasionally be found in the late phases of the product development process (PDP), such as in training and in maintenance. Head-mounted displays (HMDs) are typically used for AR applications. HMDs still show deficiencies in terms of ergonomics and image quality. Looking at the development of VR technology, it can be stated that VR began its triumphal procession only after replacing HMDs by immersive projection technology (IPT) such as PowerWalls, CAVEs, Virtual Tables. Projection-based Augmented Reality enhances such environments towards augmented reality applications. We believe that this concept opens new application possibilities for AR.
