In much the same way that video lagged behind sound on early Blu-ray players, the F-35’s onboard computer takes time to figure out where the pilot is looking and to display the appropriate camera feed. Another problem is “jitter.” Unlike a heads-up display, which is bolted to the airplane, the F-35’s helmet-mounted display is designed to be worn by pilots whose heads bounce around in flight. The image created by projectors on both sides of the helmet shakes in front of the pilot’s eyes.
