Gaze-based touchdown point selection system and method
First Claim
Patent Images
1. A method of selecting a touchdown point for a vertical takeoff and landing aircraft, comprising the steps of:
- measuring rotational movement of one or both eyes of a user with respect to the user'"'"'s head and relative to an image being rendered on a display screen;
determining an updated touchdown point location from the measured rotational movement;
rendering an updated touchdown point at the updated touchdown point location on the display screen;
receiving input from a user interface;
supplying fine-tuning touchdown point location data in response to the input from the user interface;
determining a further updated touchdown point location in response to the input from the user interface; and
rendering, simultaneously with the updated touchdown point, a further updated touchdown point at the further updated touchdown point location on the display device.

Abstract
Methods and apparatus are provided for selecting a touchdown point for a vertical takeoff and landing aircraft. The eye movements of a user are tracked relative to an image being rendered on a display screen. An updated touchdown point location is determined from the tracked eye movements, and an updated touchdown point is rendered at the updated touchdown point location on the display screen.

8. A vertical takeoff and landing (VTOL) aircraft touchdown point selection and display system, comprising:
-
a display device coupled to receive image rendering display commands and configured, upon receipt of the image rendering display commands, to render an image; an eye tracker configured to (i) measure rotational movement of one or both eyes of a user with respect to the user'"'"'s head and relative to the image being rendered by the display device and (ii) supply eye movement data; a user interface (116) in operable communication with the processor, the user interface adapted to receive user input and configured, upon receipt of the user input, to supply fine-tuning touchdown point location data and a processor in operable communication with the display device and the eye tracker, the processor configured, upon receipt of the eye movement data, to (i) determine an updated touchdown point location and (ii) supply image rendering display commands to the display device that cause the display device to render an updated touchdown point at the updated touchdown point location, and further configured, upon receipt of the fine-tuning touchdown point location data, to (i) determine a further updated touchdown point location and (ii) supply image rendering display commands to the display device that cause the display device to render, simultaneously with the updated touchdown point, a further updated touchdown point at the further updated touchdown point location on the display device. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A vertical takeoff and landing (VTOL) aircraft touchdown point selection and display system, comprising:
-
a display device coupled to receive image rendering display commands and configured, upon receipt of the image rendering display commands, to render an image; an eye tracker configured to (i) measure rotational movement of one or both eyes of a user with respect to the user'"'"'s head and relative to the image being rendered by the display device and (ii) supply eye movement data; a head tracker configured to (i) track head movements of the user and (ii) supply head movement data; a user interface (116) in operable communication with the processor, the user interface adapted to receive user input and configured, upon receipt of the user input, to supply fine-tuning touchdown point location data; and a processor in operable communication with the display device, the eye tracker, and the head tracker, the processor configured, upon receipt of the eye movement data and the head movement data, to (i) determine an updated touchdown point location and (ii) supply image rendering display commands to the display device that cause the display device to render an updated touchdown point at the updated touchdown point location, and further configured, upon receipt of the fine-tuning touchdown point location data, to (i) determine a further updated touchdown point location and (ii) supply image rendering display commands to the display device that cause the display device to render a further updated touchdown point at the further updated touchdown point location on the display device.
