Cross-reality is a subclass of extended reality (xR) that enables transitions between different manifestations of the reality-virtuality continuum[1]: reality, augmented reality (AR), augmented virtuality (AV), or virtual reality (VR).

Cross-reality systems enable users to different manifestations in various ways, since they enable users to transition between manifestations to according to the user needs [2]. For instance, in multi-user cross-reality systems one user might experience a virtual environment through augmented reality (AR) while another through virtual reality (VR). Another example could be a user first interacting with an cross-reality system through virtual reality using a head-mounted display, and then switching to interact through augmented reality in a mobile phone.

Cross-reality systems are leaning towards ubiquitous computing, since they enable more constant and flexible use, as they can be accessed through a variety of devices from different manifestations[3]. Therefore, researchers assume that in the future, extended reality (xR) will see an increase in cross-reality applications[4].
