Abstract

Augmented reality devices overlay digital content above our visually perceived real world and enable new ways of collaboration, communication, interaction, and perception. Extant research explores the conceptual foundations, technical prerequisites, and actual implementation of augmented reality in various domains. We lack a concept explaining the comprehensive range of digital layers in a holistic extended reality environment to understand how, when, and why users, for example, want to access or share information. This paper presents the extended perception layer (XPL) concept serving as the groundwork for users' interaction with augmented reality. The XPL concept describes the differentiation of three digital layers and suggests how accessing information, sharing content, and interacting with each other can be done within the layers. We contribute with the XPL concept and a corresponding research agenda to further explore the possibilities of augmenting users' visual perception.
