Apparatus, system, and method for determining a user position and progress along a path
First Claim
1. A position detection device comprising:
- one or more memories that store a set of position points defining assigned locations within one or more physical areas;
a communication interface for communicating with one or more signal sources, wherein each of said one or more signal sources is located at one of the assigned locations proximate to the position detection device, each of the signal sources having information about its assigned location, each of the signal sources comprising at least one radio frequency wireless 1o identification tag that is stimulated by at least one signal sent from the communication interface and that returns the information to the communication interface;
a path process that defines one or more paths connecting one or more of the position points in response to a user query, the path process further accessing the information from one or more, of the signal sources to determine a progress of the position detection device through the physical area as defined by the path; and
an interface that communicates the progress of the position detection device through the physical area to the user.

Abstract
A device has one or more memories that store a set of position points defining respective locations within one or more physical areas. A communication interface on the device communicates with one or more signal sources located at one or more of the respective locations proximate to the position detection device. Each of the signal sources responds to the device with information about the respective location. A path process defines one or more paths connecting one or more of the position points in response to a user query. The path process accesses the information from one or more of the signal sources and determines the progress of the device user through the physical area as defined by the path. A user interface communicates the progress through the physical area to the user.

7. A method for determining a position of a user comprising the steps of:
- storing in a memory a set of position points defining assigned locations within one or more physical areas;
communicating with one or more signal sources, wherein each of said one or more signal sources is located at one of the assigned locations proximate to a position detection device, each of the signal sources having information about the respective assigned location, each of the signal sources comprising at least one radio frequency wireless identification tag that is stimulated by at least one signal sent from the communication interface and that returns the information to the communication interface;
defining one or more paths connecting one or more of the position points in response to a user query;
accessing the information from one or more of the signal sources to determine a progress of the position detection device through the physical area as defined by the path; and
communicating the progress of the position detection device through the physical area to the user. - View Dependent Claims (8, 9)
