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.
