One of the latest trends of ubiquitous Information Systems is the use of smartglasses, such as Google Glass or Epson Moverio BT-200 that are connected to the Internet and are augmenting reality with a head-up display. In order to develop recommendation agents (RAs) for the use at the point of sale, researchers have proposed to integrate a portable eye tracking system into such smartglasses (Pfeiffer et al. 2013). This would allow providing the customer with relevant product information and alternative products by making use of the customer’s information acquisition processes recorded during the purchase decision.
