Teaching medical students can be expensive and time-consuming—and, in the COVID-19 era, risky. The new application HoloScenarios, released in June, allows students wearing a mixed-reality headset to interact with holographic patients who have common respiratory conditions, including asthma, anaphylaxis, and pneumonia, and monitor how they react to treatments. Dr. Arun Gupta, a consultant at Cambridge University Hospitals who helped create the learning tool’s Respiratory Module, says the program will expand access to training by allowing students to practice remotely. “The ability to simulate real-life responses allows you to train on more complex conditions—and also to fail safely,” Gupta says.
