Method and System to Locate and Navigate Amongst Objects in Enclosed Areas

Disclosed is a method and system to locate and navigate amongst objects in enclosed areas. Use of short range wireless networks eliminates dependency on other common location and navigation methods that fail to work within the confines of enclosed areas or around strong electric or magnetic fields.

The method and system to locate and navigate amongst objects in enclosed areas proposes a two coordinate method and system to be implemented on ordinary handheld devices that are short range wireless network compatible. The two coordinate references may be obtained from two kinds of emitters. The first type of emitter refers to a strong signal emitter that can emit across an enclosed area while the second type of emitter is a relatively short ranged and weak signal emitter that can emit signals within its proximity. The ordinary handheld device may be a cell phone or any other mobile hand held device that may be compatible with short range wireless networks such as, but not limited to, Bluetooth or Wi-Fi. The handheld device is enabled via a method or an application to receive signals from the first and second types of emitters and interpret them to locate and navigate through objects within the confines of the enclosed area.

The first emitter emits a signal; for example a macro beacon that emits a macro signal. The second emitter emits a second signal, for example a micro beacon that emits a micro signal. The macro signal contains data and location of all micro beacons within the enclosed area, while the micro signal contains the grid location of corresponding micro beacons and any other data regarding any object of interest within close vicinity of the micro beacon. The handheld device may be enabled with an application to read and interpret the micro and macro signals. The method and system thus provides for locating objects and navigating amongst them in enclosed areas using macro and micro beacons along with any handheld device that may be compatible. The disclosed method and system generates a dynamic map based on the location of a user and the

The signals may contain information on objects of interest as codes that may be read by the application on a handheld device. Likewise, any object other than objec...
