Augmented Reality Smart Glasses are an emerging new wearable technology that integrates virtual information in a user’s view-field. In this article, the authors discuss the opportunities of smart glasses in the context of Enterprise Social Networks (ESN). A proposed conceptual model is developed that demonstrates the underlying mechanisms that drive smart glasses ESN adoption on a firm level. Furthermore, on the individual employee level, the authors propose the antecedents to active and passive use. The theoretical contribution is a comprehensive hierarchical model that extends prior technology acceptance and ESN research. On the managerial front, the article provides guidance to managers who aim at achieving competitive advantages by improving knowledge management through the use of new wearable Augmented Reality technologies.
