US Patent 10254544 Head tracking accuracy and reducing latency in dynamic environments

A display system includes a transparent display configured to be worn by a pilot of an aircraft and configured to display information from an image source while allowing the pilot to view a scene, and one or more sensors configured to acquire sensor data indicative of a current orientation and motion of at least one of an eye, a head, and a body portion of the pilot. The display system also includes a controller configured to determine the pilot's current viewpoint of the scene based on the sensor data; determine the pilot's future viewpoint of the scene based on the sensor data and the pilot's current viewpoint of the scene; and cause the image source to provide the display information to the transparent display based on the pilot's determined future viewpoint of the scene to allow the pilot to view the display information and the scene together.
