Holograms trained medical students and stroke victims used robotic legs; many life-changing health developments happened in 2022.

Cambridge University Hospital and Los Angeles-based tech company GigXR developed an application called HoloScenarios to train medical students. It uses holograms to replace actors who pretend to be sick, which allow trainee doctors to assess patients’ symptoms and treat them without a hospital.

The Da Vinci Xi robot helps doctors perform surgeries in South Africa. An immersive 3D console controls the robot’s four arms in real time for complex procedures such as colorectal and gynaecological surgeries.

A driving simulator teaches teens with ADHD to keep their eyes on the road, which causes safer driving. Participants wear eye-tracking glasses that monitor head and eye movements, and they are alerted when they look away from the road for two or more seconds. At the start, they averaged 22 long glances away from the road per 15-minute drive. Months later, the number dropped to about 15 long glances in the trained group.

Difficult words: hologram (a laser makes this image that looks solid or real), console (the control unit of a computer), colorectal (the body’s large bowel and its lowest parts).
