  • Patent number: 9285236
    Abstract: A navigation method, apparatus, and a computer readable medium for a mobile terminal support a display mode that provides a good field of view and enhanced readability. An input signal for enabling a route guidance function is received. Map data for route guidance is outputted when the route guidance function is enabled. Whether to activate a heads-up display (HUD) mode is determined. When the HUD mode is activated, only preset guidance information items that are extracted from the map data are displayed. Hence, the driver does not have to look away from the road to view the map on the screen, significantly reducing the risk of traffic accidents. Simplified route guidance information is provided to solve poor map readability due to screen size limitations of a mobile terminal.
