Movie ticket seat picker

It's not easy to touch such a small element as a seat in a movie theater. I came up with an idea of using lower part of the screen as a touchpad and made a prototype.

Unfortunately I was able to do it only with one row, but I guess it conveys an idea, especially that ProtoPie allows to do great things with haptic feedback. Since it's just a video, there's no way you can feel the vibration, so I've made that little ripple effect around the button.

Also, the ticket is moving as you tilt the device. It's a subtle motion, but I like it.

Tell me what you think! Cheers.
