Problem with sliding over buttons.

Hey there, I built a LED-Matrix (10x6 ws2812b leds) and connected it with bluetooth to my arduino. Now I placed buttons like the Matrix. When I press the first button the first led going to blink for a half second..when I press the second button the second led ist going to blink for a half second and so on. 

Now I want that the leds going to blink when I slide over the screen. But when I for example slide over the first button to the second, the second button dont work because I did not lift up my finger from my screen. The first button is still active till i lift up my finger from the screen. Is there other ways to do it? I need something that deactivate a button when my finger is not longer touching it but without to lift up my finger only to slide the finger away from it. SORRY FOR MY VERY BAD ENGLISH.

try the canvas and use image sprites as buttons instead
