<p>A portable electronic device, like a cellular telephone (100) for example, includes software for executing a method for presenting directional indicator information to a user on a display (102). The device receives geographical information about its location, orientation information of its alignment and geographical information about a landmark of interest. The device then calculates a destination angle relative to the orientation information. The device then presents directional information, for example an arrow (104), to a user. In one exemplary application, Muslims are able to select Mecca (103) as the landmark of interest. The device then uses information about its own location, the orientation of the device and the location of Mecca to present an arrow on the display indicating the proper direction for the Muslim to align themselves for prayer in accordance with the teachings of Islam.</p> |
