A glass slab you trained yourself to feel buttons that were never there.
means A flat touch-sensitive surface, usually on a laptop, that translates the movement and taps of your finger into cursor control instead of using a separate mouse.
from A plain compound of "track" — to follow a moving thing — and "pad," a flat cushiony surface. The "track" half is the older idea: pointing devices were called trackballs because you literally tracked a rolling ball. When engineers flattened that ball into a sensing plate in the late 20th century, the name followed the form: a pad you track on. "Trackpad" and "touchpad" grew up side by side, with "trackpad" leaning toward Apple's branding and "touchpad" the more generic term.
