Integrating augmented reality in the assembly domain - Fundamentals, benefits and applications

Augmented Reality (AR) is a new form of human-machine interaction which overlays computer-generated information on the real world environment, e.g. through a semi-transparent, head-mounted display. With AR, presented information is derived from the real environment and is thus context-sensitive. Augmented Reality can therefore enhance a user's view with virtual information that is sensitive to the current state of the surrounding real world. While Virtual Reality Technology (VRT) is commonly used in the automotive and aircraft industry, there exists few research approaches in the field of Augmented Reality. This contribution gives a detailed introduction to AR systems, and describes the capabilities and benefits of AR in the field of assembly. As an application, a modular AR system for guiding manual assembly and for use in assembly planning is described. Furthermore, a method for integrating AR into the planning process of manual assembly stations is presented.
