Patent ID: 8754866

Claim:
A system comprising: a plurality of mobile devices including a first mobile device and a second mobile device, the mobile devices configured to communicate on a wireless network, and the mobile devices stationed to define a detectable region based on respective locations of the mobile devices so that objects within the detectable region are detectable by each of the plurality of the mobile devices; and a processor configured to: communicate with the mobile devices; define a detection area within the detectable region based on detection criteria; detect entry and removal of a detectable object into the detection area; define a coordinate system for the detection area; determine a set of coordinates for the detectable object within the coordinate system, the set of coordinates indicative of a location of the detectable object in the detection area, the set of coordinates determined based on: a distance between the first mobile device and the second mobile device, a distance between the first mobile device and the detectable object, and a distance between the second mobile device and the detectable object; and control an application based on the set of coordinates determined for the detectable object.
