Abstract

A vehicle simulation such as for example a driving game can be provided by displaying an image of a steering wheel on a touch sensitive screen. Touch inputs are used to control the rotational orientation of displayed steering wheel. The rotational orientation of the displayed steering wheel is used to apply course correction effects to a simulated vehicle. Selective application of driver assist and different scaling of touch inputs may be provided.

Claims

1. A method of simulating a vehicle control comprising:

displaying an image of a vehicle control device on a touch screen;

detecting positional changes in a touch input provided to the touch screen; and

rotating the displayed device image by an amount and in a direction detetermined at least in part in response to the detected touch input positional changes,

wherein said rotation amount and direction is used to change the course of a simulated vehicle displayed on a further screen.

2. The method of claim 1 wherein said touch input is used to define an initial vector and a final vector relative to a predetermined point, and wherein said rotating comprises rotating said device image by an amount responsive to the angle between said initial vector and final vector.

3. The method of claim 1 further including applying selectively the user assist in response to detection of said touch input within a predetermined zone on said touch screen.

4. The method of claim 1 further including contacting the touch screen with a stylus to provide said touch input.

5. The method of claim 1 further including contacting said touch screen with a wearable thumb pad to provide said touch input.

6. The method of claim 1 further including simulating vibration of said displayed device.

7. The method of claim 1 further including changing the scaling of said touch input depending at least in part on type of input device used to contact said touch screen.

8. The method of claim 1 wherein said device comprises a steering wheel.

9. A method of providing a simulated vehicle control input comprising:

contacting a touch sensitive surface at a first point;

moving said touching contact from said first point to a second point;

calculating the angle between a first vector defined between a predetermined point and said first point, and a second vector defined between said predetermined point and said second point; and

applying a simulated steering correction to a simulated vehicle at least in part in response to the angle formed between said first and second vectors.

10. A vehicle simulation apparatus comprising:

a portable handheld housing including first display screen, a second display screen and at least one control input;

a first graphics processing unit that displays an image of a simulated control device on said first display;

a second graphics processing unit that displays an image of a simulated vehicle on said second display;

a processor, coupled to said first and second graphics processing units and to said control input device, said processor changing said displayed image of said control input device in a predetermined manner by a predetermined amount responsive to said user input, and applying a corresponding course correction to said simulated vehicle displayed on said second display.

11. The apparatus of claim 10 wherein at least one of said displays with a touch screen, and said processor is adapted to receive touch inputs and provide said display changes at least in part in response thereto.

12. The apparatus of claim 10 further comprising means for selectively providing vehicle control assist and blending said assist with said control input to generate said corresponding course correction.

13. The apparatus of claim 10 wherein said simulated control device comprises a steering wheel.

14. The apparatus of claim 10 wherein said simulated control device comprises a visual target.

15. The apparatus of claim 10 wherein said processor reduces course correction amount over time in response to detecting the absence of a touch input.

16. The apparatus of claim 10 wherein said processor calculates a delta steering value based on scaled left/right movement of a touch input.

17. The apparatus of claim 10 wherein said processor calculates an angle that the simulated vehicle should be pointed to be aligned with a track.
