What I learned from Apple TV HIG:
1.Difference between the three gestures
a)swipe – directions, going through large volumes of content.
b)click – triggering actions.
– hold + click = enter an edit mode.
c)tap – directions, going through content one by one.
2.Design for different focusable item states.
3.Parallax is a subtle visual effect used throughout the system to convey depth and dynamism when an element is in focus. Through image layering, transparency, scaling, and motion, parallax produces a 3D effect with a sense of realism and vitality.
