I want to write a app to imitate Braille code. But I don't know how to handle multi touch button at the same time.
Can someone help me a simple like: click button 1, button 2 at the same time, it'll print "a". click button 1,2,3 at the same the it'll print "c".
My idea that: I'll put some button clicked in the amount of time in an array . then I'll process this array. But i don't know how to do that.
