Travelers on a public transport system such as metro rail are often engrossed in viewing content on their mobile devices and may forget the route segment they are currently on and can miss an upcoming transfer point, leading to time-consuming re-routing. This disclosure describes techniques that provide, via a mobile device and/or a wearable computer, subtle visual hints to a traveler regarding their current location on a multi-hop public transport system such as metro rail and upcoming transfers. The visual hints can be provided by matching the color of operating system controlled user interface elements such as wallpaper, status indicators, notification panels, etc. or via application UI. Application behavior can also be updated to account for the traveler’s present location and travel route, e.g., by displaying search results that match the route, displaying search results with a similar color as a route segment that it is close to, etc.
