It’s a knob that spring back to its origin when let go, that can move ~45 degrees or ~1/4” each axes(subjectively). It feels a bit like those old bobbing dashboard toy in hand. Mechanically, it’s something like an Rx/Rz two-axis joystick with sliding knob part on top that can be slid in X/Y, pushed/pulled in Z and twisted in Ry as well. All axes are spring centered.
