The spinners are weighted knobs that you can spin freely in either direction. Inside, a rotary encoder produces two square wave signals (A and B) that are 90 degrees out of phase. By counting the edges and checking which signal leads, you can determine both the speed and direction of rotation. We sample these at 1kHz in firmware and report the accumulated counts as an axis value in the HID reports.
