trackpady

Trackpady is a term used to describe a class of input surfaces that extend conventional trackpads with additional sensing and input modalities. It is not tied to a single product, but rather a design concept used in hardware and software discussions to denote trackpad-like devices that offer features beyond basic cursor control, such as pressure sensitivity, haptic feedback, tilt sensing, and enhanced gesture sets.

Typical trackpady hardware combines a capacitive multi-touch surface with one or more sensing layers for force or pressure, some form of haptic actuator for tactile feedback, and sometimes tilt or azimuth sensing for stylus-like input. They are produced as built-in laptop touchpads or as external USB-Bluetooth devices and vary in size from compact palm-size pads to large external surfaces.

Software support usually includes driver layers that expose gestures (for example, multi-finger swipes, pinch-to-zoom, or force-press menus) and configuration utilities for sensitivity and mapping. Many implementations rely on standard HID (human interface device) profiles augmented by vendor-specific extensions and have partial cross-platform support via open-source libraries.

Trackpady is used by graphic designers, software developers, and accessibility advocates who need finer control or more expressive input than a traditional trackpad offers. Reception is mixed: the term covers a wide range of technologies, so capabilities depend on the specific device and software ecosystem.
