A method of providing help prompts relating to the use of human-machine interfaces within a vehicle, the method comprising: monitoring user interaction with the human-machine interfaces within the vehicle; assessing a monitored user interaction against pre-determined available user interaction options; outputting a help prompt to the user in dependence on deviations between the monitored user interaction and the pre-determined available user interaction options. Aspects of the invention include the pre-determined available user interaction options comprising: optimal routes through a menu hierarchy between interface menu levels; shortcut buttons to jump between interface menu levels; alternative user input interaction methods; swipe gestures versus on-screen scroll buttons; available user-selectable menu options at a given menu level within a menu hierarchy. The help prompt may comprise a visual dialog box on the display screen, text based help message, audio message, icon/graphical based help, and the help prompt may relate to available user input interaction methods, unused user-selectable menu options, unused shortcut functions. Monitoring user interaction may comprise monitoring user workload, wherein the workload is determined via one or more of vehicle speed, acceleration, steering inputs to wheel, traffic density, road situation etc.
