A similar issue arises in aviation. In the cockpit, airspeed and altitude used to be presented on a dial like a watch (one hand in the case of airspeed, two hands or even three in the case of altitude). In modern cockpits with screens, they could be presented like that, or just as numbers, but they are presented as infinite bands that move up and down. One sees the number on it, but also perceives movement (and how fast it moves) "out of the corner of an eye". Maybe it combines the advantages of both. See here, for example, for both styles: https://www.flight-mechanic.com/pitot-static-pressure-sensing-flight-instruments-part-one/ https://www.flight-mechanic.com/pitot-static-pressure-sensin... I wonder what studies were made regarding this design.
