Augmented reality (AR) is increasingly considered to support scenarios of co-located and remote collaboration. Thus far, the core goal has been advancing the supporting technologies and assessing how they perform to inform design and development, thus providing support toward their maturity. Nevertheless, while understanding the performance and impact of supporting technology is indisputable groundwork, we argue that the field needs to adopt a framework that moves from answering questions about the proposed methods and technologies to a more holistic view, also encompassing collaboration. However, moving toward this goal challenges how evaluations are designed, adding complexity and raising several questions about what needs to be considered. In this article, we briefly examine the different dimensions entailed in collaborative AR and argue in favor of a distinctive evaluation framework that goes beyond current practice and sets its eyes on the elements that allow judging how collaboration unfolds while informing the role of the supporting technology.
