System and method for calibration and mapping of real-time location data
First Claim
1. An apparatus comprising:
- a scanning device that scans a signal of decodable indicia on an area of a physical object wherein decoding said decodable indicia results in a message that contains information describing said physical object;
a memory;
a motion sensing device;
wherein a point of origin of said apparatus described by information in the message at said area of said physical object is stored into memory; and
wherein, responsive to the physical movement of said apparatus, a spatial position of said apparatus is determined relative to said point of origin based on a plurality of values received from said motion sensing device.

Abstract
A method of mapping the location of at least one object in three dimensional space, relative to an initial point in three dimensional space by an EIR terminal which contains a microprocessor, memory, a scanning device, a motion sensing device, and a communication interface. The method includes scanning a signal of decodable indicia located at a pre-defined area of a physical object, locating the decodable indicia within this signal, decoding the decodable indicia into a decoded message. The decoded message is an identifier for said physical object, which is then displayed. After receiving an interface command, the EIR terminal is placed in mechanical contact with the pre-defined area of the physical object and a first spatial position is stored as a point of origin in the EIR terminal.
