Proto’s holographic tech makes it feel like a remote doctor is sitting in the same room.

On a recent weekday, I stood in front of a phone-booth-sized box—seven feet tall, four feet wide, and two feet deep—talking to a life-sized, three-dimensional image of a doctor who was 2,000 miles away in Tennessee. This wasn’t a Zoom call: It felt like he was in the room.
