Surgical Video Summarization: Multifarious Uses, Summarization Process and Ad-Hoc Coordination

While surgical videos are valuable support material for activities around surgery, their summarization demands great amounts of time from surgeons, resulting in the production of very few videos. We study the practices involving surgical video to motivate and inform the future design of tools for their summarization. Through interviews and observations in a feld study, we fnd that (1) video summaries provide an important support for surgery, being used for self-improvement, education, discussing cases, scientifc research, patient communication and as legal resources; (2) video summarization follows a process hindered by the loss of knowledge that originates during recording; and, (3) surgeons develop ad-hoc coordination strategies which involve using the video itself for articulation work, making it both the feld of work and coordination artifact. We discuss ways in which tools can facilitate capturing knowledge during live action using these strategies.
