Abstract: A first region of interest is determined by user input to a map interface. A set of locations of items of interest is determined located proximate to the region of interest. A background and a first set of representations are presented against the background on the device display according to a location and an orientation of the device, each representation of a respective item of interest located in the first region of interest.

Abstract: A region of interest is determined by a location and an orientation of a device, wherein the region of interest is proximate to the device. A set of locations of items of interest is determined with respect to the region of interest. A background and a first set of representations against the background is presented on the device display according to the location and orientation of the device. Each representation is of a respective item of interest located in the region of interest. The region of interest is adjusted with a pinch gesture on the background, however, the presenting of the background does not change in response to the pinch gesture. Instead, the set of locations of one or more items of interest is determined with respect to the adjusted region of interest, and a second set of representations is presented against the background. Each representation of a respective item of interest is located in the adjusted region of interest.

Abstract: Presenting locations of individuals on a display of a portable device is described. A region of interest is determined by a location and an orientation of the portable device. The region of interest is a cone of interest radiating away from the location of the portable device in a direction of orientation of the portable device. A set of locations of one or more individuals of interest is determined with respect to the cone of interest. An orienting background and a first set of representations against the orienting background is presented on the display according to the location and orientation of the display. Each representation is of a respective individual of interest located in the cone of interest. The orienting background contains a positional cue of a landmark which the portable device is oriented toward. The cone of interest is adjusted with a pinch gesture on the orienting background.
