Exploring Situated Instructions for Mixed Reality (MR) Remote Collaboration: Comparing Embedded and Non-Embedded Annotations
Remote collaboration using Mixed Reality (MR) enable off-site experts to assist on-site collaborators needing guidance. Different types of visualizations have been proposed for sharing situated information, e.g., embedded, non-embedded, others. However, the effectiveness of these visualizations have not been compared. This work describes a user study with 16 participants, aimed at comparing two conditions: C1 - Embedded and C2 - Non-Embedded annotations during a real-life scenario of remote maintenance. Two distinct devices were used: Hand-Held Device (HHD) and a Head-Mounted Display (HMD). This last using Embedded annotations was considered the better alternative, while HHD using Non-Embedded annotations were rated lower from all conditions analyzed.
