Abstract

A method and implementing computer system are provided in which an interface device is designed to provide an interface between a remote controller (RC) device for controlling the operation of a vehicle, and a computer system such as a personal computer. The interface device is enabled to receive RC signals from the RC device and convert those RC signals to input signals which are input to a computer system. The interface device builds a translation table for converting the RC or joystick signals to appropriate input signals for the type of vehicle in a particular application. A user is thereby enabled to manipulate an RC device such as a joystick and observe how the user'"'"'s input joystick movement affects the movement of a simulated controlled vehicle which is displayed on a display screen of the computer system.

Claims

1. An interface circuit for use in coupling a remote control (RC) device and a computer system, said RC device including at least one joystick by which a user is enabled to input selected control functions, said computer system having a computer input port for receiving input signals from said interface circuit, said computer system further including a display device, said computer system further including means responsive to said input signals for effecting changes in a displayed image presented on said display device, said interface circuit comprising:

RC signal receiving means arranged for receiving RC signals transmitted from said RC device, said RC signals being representative of said selected control functions;

interface circuit output terminal means arranged for providing said input signals to said computer system; and

signal converter means connected between said RC signal receiving means and said interface circuit output terminal means, said signal converter means being selectively operable for converting said RC signals to said input signals to effect display changes to said displayed image based upon said input signals, said interface circuit further including a memory device, said computer system being selectively operable for building a correlation database for storage in said memory device, said correlation database including information correlating said control functions and said display changes.

2. The interface circuit as set forth in claim 1 wherein said control functions include movements of said joystick, and said display changes include changes of vehicle images presented on said display screen corresponding to said movements of said joystick.

3. The interface circuit as set forth in claim 2 wherein said vehicle images comprise images representative of predetermined aircraft types.

4. The interface circuit as set forth in claim 2 wherein said vehicle images comprise images representative of predetermined automobile types.

5. The interface circuit as set forth in claim 2 wherein said vehicle images comprise images representative of predetermined boat types.

6. The interface circuit as set forth in claim 2 and further including means for supporting a number of different types of said joystick, said interface circuit being operable to build said correlation database based upon a particular type of joystick being used.

7. The interface circuit as set forth in claim 6 wherein said interface circuit is selectively operable for receiving movement limit signals from said RC device, said movement limit signals being representative of limits of mechanical movement of said joystick being used, said interface circuit being further selectively operable for correlating said movement limit signals to a screen size of said display device.

9. The interface circuit as set forth in claim 1 wherein said interface circuit is solely connected to said computer system by a Universal Serial Bus (USB) connector device wherein input signals related to each of said control functions are transmitted over a predetermined different ones of connector pins of said USB connector device.

10. The interface circuit as set forth in claim 9 wherein said connector device is an RS232 connector device.

11. The interface circuit as set forth in claim 1 wherein said interface circuit is included on a circuit board within said computer system.

8. The interface circuit as set forth in claim 8 wherein said correlating is accomplished each time said computer system is started-up.

12. A method for initializing a joystick-controlled computer system in which mechanical movements of said joystick are translated into corresponding movements of an image presented on a display screen, said method comprising:

powering-up said computer system;

receiving control signals from said joystick, said control signals being identified with a particular type of joystick;

building a correlation table based upon control signals received from said joystick, said correlation table including information relating physical movements of said joystick to corresponding movements of said image on said display screen.

14. The method as set forth in claim 13 and further including:

sending test signals to said joystick after said power-up, said test signals being effective to test the operability of a communication channel between said joystick and said computer system;

determining status of said operability; and

providing an indicium representative of said status.

15. The method as set forth in claim 14 wherein said indicium is located in said computer system to be perceived by a user of said joystick.

16. The method as set forth in claim 15 wherein said indicium is a light-emitting diode (LED).

17. A storage medium including machine readable coded indicia, said storage medium being selectively coupled to a reading device, said reading device being selectively coupled to processing circuitry within a computer system, said reading device being selectively operable for initializing a joystick-controlled computer system in which mechanical movements of said joystick are translated into corresponding movements of a vehicle image presented on a display screen, said method comprising:

powering-up said computer system;

receiving control signals from said joystick, said control signals being identified with a particular type of joystick;

building a correlation table based upon control signals received from said joystick, said correlation table including information relating physical movements of said joystick to corresponding movements of said vehicle image on said display screen.

18. The medium as set forth in claim 17 wherein said vehicle image comprises an image of a selected type of aircraft.

19. The method as set forth in claim 18 and further including:

sending test signals to said joystick after said power-up, said test signals being effective to test the operability of a communication channel between said joystick and said computer system;

determining status of said operability; and

providing an indicium representative of said status.
