Apparatus, comprising:

• a processor;
• computer memory holding computer program instructions executed by the processor for presenting locations of individuals on display of a portable device, the computer program instructions comprising:
• program code, operative to determine a region of interest by a location and an orientation of the portable device, wherein 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;
• program code, operative to determine a set of locations of one or more individuals of interest with respect to the cone of interest;
• program code, operative to present an orienting background and a first set of representations against the orienting background on the display according to the location and orientation of the portable device, each representation of a respective individual of interest located in the cone of interest, the orienting background containing a positional cue of a landmark which the portable device is oriented toward;
• program code, operative to adjust the cone of interest with a pinch gesture on the orienting background;
• program code, operative to determine a set of locations of one or more individuals of interest with respect to the adjusted cone of interest;
• and
• program code, operative to present a second set of representations against the orienting background.
