Design considerations for combining augmented reality with intelligent tutors.

•The effectiveness of Intelligent Tutoring Systems in psychomotor domains can potentially be enhanced by combining them with Augmented Reality paradigms.•Due to ITS complexity and design, work on the use of ITSs with AR is significantly limited and how these paradigms work together is not well understood.•Existing work shows that combining ITSs with AR enhances significantly enhances performance and learning.•Combining AR with ITS requires a gateway interface and networking capabilities in both the ITS and the AR application, due to non-standardised mechanisms used in these systems.•Additional research on the design of the interface; authoring systems for ITSs in AR and their learning effectiveness is required.
