  <!-- The noise floor (px) for predicted distances.

       As the model is trained stochastically, there is some expected minimum

       variability in its output. This can be a UX issue when the input device

       is moving slowly and the variability is large relative to the magnitude

       of the motion. In these cases, it is better to inhibit the prediction,

       rather than show noisy predictions (and there is little benefit to

       prediction anyway).

       The value for this parameter should at least be close to the maximum

       predicted distance when the input device is held stationary (i.e. the

       expected minimum variability), and perhaps a little larger to capture

       the UX issue mentioned above.
