Stabilized Annotations for Mobile Remote Assistance
summary
Compares anchored stabilized annotations (AR targets) with non‑stabilized overlays across tablets and head‑mounted displays, running two user studies (16 pairs first study, 6 pairs second). Finds stabilized annotations are preferred but not faster, and 61% of marks are ephemeral—mostly procedural and pointers—so a simple freeze-frame (F2)—freezing video for two seconds while drawing—is easy to implement and surprisingly effective, though it causes temporary loss of context that can be mitigated with a live thumbnail.
