Hybrid digital—analog time displays
Abstract:
Hybrid digital-analog time displays are provided to tell time with digital hour and minute values, as well as simultaneous analog tracks that are coordinated in lengths with the minute values. These displays are shown in four successive quadrants and enable users to view current time exactly from the digital values and approximately from the analog tracks.
