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.
Claims17
A navigation method for a mobile terminal supporting a route guidance service, comprising:
- outputting, by a display unit, map data for route guidance;
- measuring a slope of the mobile terminal;
- and
- outputting, by the display unit, in response to a determination to activate a heads-up display (HUD) function based on comparison of the slope of the mobile terminal to a value, preset guidance information in an upside-down reversed form,
- wherein the preset guidance information is extracted from the map data, and
- wherein outputting the preset guidance information comprises converting and outputting a background color to a color contrasted with a color presenting the preset guidance information.
A navigation apparatus for a mobile terminal supporting a route guidance service, comprising:
- a display unit configured to output map data for route guidance, and to output, in response to a heads-up display (HUD) function being selected, preset guidance information in an upside-down reversed form, wherein the preset guidance information is extracted from the map data;
- a sensor unit configured to measure a slope of the mobile terminal;
- and
- a control unit configured to determine to activate the HUD function in response to the input signal for selecting the HUD function being generated and based on comparison of the slope of the mobile terminal to a value;
- and to convert and cause the display unit to output a background color to a color contrasted with a color presenting the preset guidance information.
A non-transitory computer readable medium containing software instructions operable when executed for supporting a route guidance function in a mobile terminal, the software instructions when executed perform a method comprising:
- providing map data for route guidance when the route guidance function is enabled;
- and
- outputting, in response to a determination to activate a heads-up display (HUD) function based on comparison of the slope of the mobile terminal to a value, preset guidance information in an upside-down reversed form,
- wherein the preset guidance information is extracted from the map data, and
- wherein outputting the preset guidance information comprises converting and outputting a background color to a color contrasted with a color presenting the preset guidance information.
