Controlling by using phone numbers ?

Hi …

I wanna make a game (car racing) for TV show .
when the child call to the TV, he will be able to controlling his car by using the phone numbers ( 0-9 ).

2 = up

4 = left

6 = right

8 = down

Can I do that with unity and how ?

thanks …

Sure. You just need a hardware/software interface to map the DTMF signals corresponding to the 2, 4, 6, 8 buttons to the Up, Left, Right, and Down axes defined in Unity’s Input Manager.
