Abstract

An aircraft control system for a user of a simulated aircraft. The system includes input devices for controlling the simulated aircraft, a video display having three-dimensional graphics, modeling software for determining position and orientation information based on desired direction of flight obtained through the input devices. User controls desired direction of flight through the input devices, thus controlling aircraft. The aircraft control system may be embodied as a flight game.

Claims

a video device for presenting the user with a view of a simulated environment;

a processor executing a model of aircraft parameters, wherein the model is responsive to the desired direction of flight for determining position and orientation of the simulated aircraft;

wherein the processor analyzes rotation moments needed to be applied to the simulated aircraft to fly along the desired direction of flight and modifies a simulated aircraft state to align the aircraft with the desired direction of flight; and

at least one input device for controlling the desired direction of flight.

2. The system of claim 1, further comprising showing a graphical element on the video device corresponding to the desired direction of flight.

3. The system of claim 2, wherein the graphical element is a circle.

5. The system of claim 2, wherein in response to the graphical element moving on the video device, parameters of the simulated aircraft, including its ailerons, elevator and rudder are changed so as to bring a direction of flight of the simulated aircraft aligned with the desired direction of flight.

6. The system of claim 1, further providing a camera view of the simulated aircraft such that the desired direction of flight is in a center of the camera view.

7. The system of claim 1, wherein the system provides, as its outputs, an aileron control value, and elevator control value, and a rudder control value, which correspond to physical parameters of the simulated aircraft.

8. The system of claim 1, wherein the at least one input device is any of a mouse, a touch screen, a touchpad, a gamepad, a virtual reality glove or virtual reality headtracker, a WiiMote, a PS Move, a Razer Hydra, a Kinect, a gesture recognition device, a trackball, a keyboard, and a joystick.

9. The system of claim 1, wherein the rotational moments are calculated based on a full aerodynamic model of the simulated aircraft.

10. The system of claim 1, wherein the model receives, as its inputs, current aircraft linear speed, current aircraft linear acceleration, current aircraft angular speed, current aircraft angular acceleration, current aircraft orientation, and the desired direction of flight.
