BLIND PEOPLE CAN ALREADY DIRECT-VIRTUALLY
A computer engineering student at the engineering university of Colombia in the United States has created a system of sound indicators for racing games called Racing Auditory Display (RAD). The technology allows blind people to have fun at the wheel of a video game racing car.The RAD operates through a sound texture associated with the vehicle engine placed in front of the player and is applied in two different sectors. The first concerns the positioning of the car on the track and is associated with the steering wheel. The sound of the vehicle will move to the left and right as it approaches the ends of the circuit. In the background, when the player turns the wheel, he is controlling the sound directly.



That is, when you hear the sound moving too far to the left, you will have to compensate the car to the right, to keep it in the center and avoid collision. The second sector refers to the understanding of the speed of the car and the trajectory in the track to anticipate the curves.

Although the system sounds simple, to maintain the fluidity of a competitive race, distinct sounds are debited simultaneously. With practice the player will be able to keep the car on the track at a considerable speed, managing to overcome all the obstacles of the road, namely more open or closed curves, where it is necessary to slow or cut the corners.
