Abstract

The invention relates to a method of display adjustment (49) for a video game system (1, 3). The system comprises a remotely-controlled vehicle (1) with a sensor (31) for sensing the attitude of the vehicle (1), and an electronic entity (3) including a display unit, the electronic entity (3) serving to control the vehicle (1) on a circuit, remotely. The method comprises the following steps: using the sensor (31) to acquire the instantaneous attitude of the vehicle (1) dynamically; dynamically estimating at least one inclination parameter of the circuit (57) from instantaneous attitude values delivered by the sensor (31); and adjusting the display (49) of the electronic entity as a function of the estimated values for the inclination parameter(s) of the circuit (57).

Claims

1. A method of display adjustment (49) for a video game system (1, 3), the system comprising:

a remotely-controlled vehicle (1) with a sensor (31) for sensing the attitude of the vehicle (1); and

an electronic entity (3) including a display unit, the electronic entity (3) serving to control the vehicle (1) on a circuit (57) remotely;

the method being characterized in that it comprises the following steps;

using the sensor (31) to acquire the instantaneous attitude of the vehicle (1) dynamically;

dynamically estimating at least one inclination parameter of the circuit (57) from instantaneous attitude values delivered by the sensor (31); and

adjusting the display (49) of the electronic entity as a function of the estimated values for the inclination parameter(s) of the circuit (57).

2. A method according to claim 1, the display (49) of the electronic entity being constituted by a video image coming from a video sensor (19) arranged on the remotely-controlled vehicle (1), with virtual elements (51) being encrusted in the video image.

3. A method according to claim 2, adjustment of the display (49) including adjusting virtual markers (51) encrusted in the display of the electronic entity, the markers (51) serving to define the circuit (57).

4. A method according to claim 1, further including a training routine having the following steps:

storing estimated inclination parameter values corresponding to a lap around the circuit (57); and

using the stored values to refine the estimate of the inclination parameter(s) of the circuit (57).

5. A method according to claim 1, wherein the circuit inclination parameter(s) are estimated by a Kalman filter.

6. A method according to claim 1, wherein dynamically estimating comprises taking a first average of the instantaneous attitude over a long term and/or a second average of the instantaneous attitude over a short term to estimate respectively a first inclination parameter of the circuit (57), and/or a second inclination parameter of the circuit, wherein the first inclination parameter comprises a slope and the second inclination parameter comprises a roughness.

7. A method according to claim 1, wherein the remotely-controlled vehicle (1) is a land vehicle, in particular a race car.

8. A method according to claim 1, wherein the electronic entity (3) is a portable unit, in particular a portable game console or a mobile telephone.

9. A method according to claim 1, wherein communication between the electronic entity (3) and the remotely-controlled vehicle (1) takes place by short-range radio transmission (5), in particular by Bluetooth or WiFi protocol.
