Design and Usability Analysis of a Mixed Reality- based CPR Assistance Prototype for In-flight Medical Emergencies

Abstract

In-flight medical emergencies, especially those requiring Cardiopulmonary Resuscitation (CPR), highlight the need for effective tools that are accessible to assist responders with basic CPR training. This work introduces a prototype of a mixed reality (MR) CPR assistance system using Microsoft Hololens-2, with the objective of guiding flight attendants through CPR procedures with improved accuracy and confidence in high-stress emergency situations. As a first study, it provides a basis for testing MR’s potential in helping non-expert responders follow critical steps during emergencies. This prototype includes step-by-step, on-screen instructions and visual cues to a 2D body model, helping users to understand the correct hand positioning and compression techniques. The study is designed to assess the possibility of a full MR CPR support system to be used for training purposes. The project shows how the system could enhance user’s understanding and potentially improve performance through guided, interactive support in the future. The outcomes of this project focus on the possibilities of further development in this area, that can empower flight attendants to act confidently in life-saving scenarios. While the current model is an initial prototype without integrated hand tracking, or real-time feedback on compression rate and depth, these features are part of future research.
