Press the red button: A user study comparing notification placement with augmented and non-augmented tasks in AR

Visual notifications are omnipresent in applications ranging from smart phones to Virtual Reality (VR) and Augmented Reality (AR) systems. However notifications can cause disruptive effects on task performance and different notification placements have been shown to have an influence on response times, as well as e.g. on user per-ceived intrusiveness and disruptiveness. We investigated the effects and impacts of four visual notification types in AR environments where a card game task was performed in AR or the real world. In a user study, we interrupted the execution of the main task with one of the AR notification types.
