Allessandro uses head movement to control a wireless pointing device.

The company will consider customers who received replacements of a “topcase” — which includes the battery, the touch-sensitive pointing device known as a trackpad, the speakers and the keyboard — or of a “keycap,” which refers to the covers for letters on the keyboard.

For the uninitiated, a trackball is a pointing device similar to a mouse, except you use a tiny rolling sphere to move your cursor instead of moving the entire device.

There is no trackpad or pointing device, however.
