ASUR++ helps a designer to specify the key characteristics of such systems and to focus on the relationship between physical objects and actions and digital information exchanges. Following a brief introduction to the notation, we illustrate its potential usefulness via examples based on the design of an augmented museum gallery. We conclude with a consideration of the integration of ASUR++ into the system development process and its augmentation via associated methods and tools. </ABSTRACT></RECORD></RECORDS></XML>
