8. The method of claim 7 , wherein the haptic output causes a deformation of the first haptic output region but not the second haptic output region or the third haptic output region.
9. The method of claim 7 , wherein:
the first haptic output region is a palm rest area; and
the second haptic output region receives the input.
10. The method of claim 7 , wherein the first haptic output region receives the input.
11. The method of claim 10 , wherein the haptic output occurs while the input is received.
12. A laptop computing device, comprising:
an upper portion;
a display housed in the upper portion;
a lower portion hingably coupled to the upper portion and comprising:
a top case defining an outer surface;
a bottom case coupled to the top case;
a keyboard on or extending through the top case; and
a trackpad region defined along the outer surface of the top case and defining:
a first haptic region;
