As the spacemouse is velocity based, there is inertia when it comes to changing direction, meaning that it's easy to overshoot or overcorrect and undershoot a UI target.
A proposed idea is to create a look-ahead buffer of the last 5 complete mouse positions, and the actual mouse position is the oldest element. If the average decerases beond a set limit, stop sending new cursor events.
I say "complete", as 3DxPoint receives X-axis and Y-axis events at different times, but always receives 0 as the last event on that axis. For example, the received values could be:
These should be put in the buffer like so: (4, 12) (15, 12) (18, 30) (0, 12) (0, 4) (0, 0). This is also for #1.
The movement in the absolute zone is quite choppy. Some sort of smoothing should be applied.
