Remote guidance on physical tasks is a type of collaboration in which a local worker is guided by a remote helper to operate on a set of physical objects. It has many applications in industrial sections such as remote maintenance and how to support this type of remote collaboration has been researched for almost three decades. Although a range of different modern computing tools and systems have been proposed, developed and used to support remote guidance in different application scenarios, it is essential to provide communication cues in a shared visual space to achieve common ground for effective communication and collaboration. In this paper, we conduct a selective review to summarize communication cues, approaches that implement the cues and their effects on augmented reality based remote guidance. We also discuss challenges and propose possible future research and development directions.
