CPR Emergency Assistance Through Mixed Reality Communication
ITS(2023)
摘要
We design and evaluate a mixed reality real-time communication system for
remote assistance during CPR emergencies. Our system allows an expert to guide
a first responder, remotely, on how to give first aid. RGBD cameras capture a
volumetric view of the local scene including the patient, the first responder,
and the environment. The volumetric capture is augmented onto the remote
expert's view to spatially guide the first responder using visual and verbal
instructions. We evaluate the mixed reality communication system in a research
study in which participants face a simulated emergency. The first responder
moves the patient to the recovery position and performs chest compressions as
well as mouth-to-mask ventilation. Our study compares mixed reality against
videoconferencing-based assistance using CPR performance measures, cognitive
workload surveys, and semi-structured interviews. We find that more visual
communication including gestures and objects is used by the remote expert when
assisting in mixed reality compared to videoconferencing. Moreover, the
performance and the workload of the first responder during simulation do not
differ significantly between the two technologies.
