Demo: More Than Just Compressions: Attentional Tunneling in Augmented Reality-Guided Cardiopulmonary Resuscitation
Cardiopulmonary Resuscitation (CPR) is a critical procedure where noticing unexpected patient changes is as vital as performing quality compressions. While Augmented Reality (AR) applications have shown promise in guiding CPR, they often focus on metrics such as compression rate and depth, which can negatively impact rescuers by inducing attentional tunneling - a phenomenon where intense focus on virtual elements causes a user to miss critical events in their physical environment. This demonstration presents an AR-guided CPR system to investigate this effect, using a mannequin with embedded LED lights that illuminate randomly during the task. Attendees will experience two variations of our AR application: one with CPR quality feedback in the form of a speed gauge and related text information, and another that adds a dynamic, in-context compression depth visualizer. By recording the reaction time to the LED stimulus and analyzing gaze allocation on virtual elements in our AR app, we will demonstrate how AR can induce attentional tunneling, even with good design intentions.
