The feature under discussion pertains to a visual setting within a navigation application designed for in-vehicle infotainment systems. This setting alters the color palette of the map interface, shifting from a predominantly light theme to a darker one. An example includes a Google Maps interface on an Android Auto system where the map background changes from white or light gray to black or dark gray.
Implementation of this function is significant for several reasons. First, it reduces eye strain, particularly during nighttime driving, by minimizing the amount of bright light emitted from the screen. Second, it enhances visibility of the map details, making roads, points of interest, and other crucial information easier to discern. Historically, demand for this feature grew as users increasingly used in-car navigation systems during all hours of the day and night, leading developers to prioritize user comfort and safety.
