Augmenting Collaborative Practices: The Hololiver Case Study.

Advances in Mixed Reality (MR) technologies are reshaping collaborative practices. The seamless integration of physical and virtual elements enhances the perception of the working environment, providing a more enriched collaborative task experience. While revealing intriguing potential across various sectors, wearing head-mounted displays (HMDs) can pose challenges in communication and in understanding others’ behaviours. This paper analyses the main elements of collaborative augmented practices through the case study of Hololiver, a MR system developed to assist surgeons in planning laparoscopic liver surgeries. The work discusses guidelines for designing interfaces to preserve awareness in MR interactions.
