Cross-Device Augmented Reality Annotations Method for Asynchronous Collaboration in Unprepared Environments

Augmented Reality (AR) annotations are a powerful way of communication when collaborators cannot be present at the same time in given environment. However, this situation presents several challenges, for example: how to record AR later consumption, align virtual and real world unprepared environments or offer users with different devices. In paper we cross-device annotation method that allows create display asynchronously without need prior preparation (AR markers, point cloud capture, etc.). This is achieved through an easy user-assisted calibration process data model any type stored on device. The experimental study carried out 40 participants has verified our two hypotheses: able visualize indoor regardless device used overall usability system satisfactory.
