Methods of determining the location of a user in an area, and user location systems
A method of determining the location of a user in an area. A user requests a transmitting device from a transmitter providing device. The transmitter providing device associates an identification code with the user, and the transmitting device transmits that identification code. One or more of receiving devices receive the identification code transmitted by the transmitting device, and send details of the received identification code to the user location determining device. The user location determining device then determines the location of the user, using the received details from the one or more receiving devices.
1. A method of determining the location of a user in an area, using:
a transmitter providing device located at a first location, the transmitter providing device further comprising a store of a plurality of transmitting devices, wherein the transmitter providing device generates a magnetic field that is above a predetermined threshold at locations within the store of transmitting devices, and the transmitting devices are arranged to transmit an identification code only when not within a magnetic field that is above the predetermined threshold;
a plurality of receiving devices distributed in different locations within the area; and
a user location determining device in communication with the plurality of receiving devices;
wherein the method comprises the steps of:
a user at the first location requesting a transmitting device from the transmitter providing device;
the transmitter providing device associating an identification code with the user;
the transmitter providing device providing the user with a transmitting device and communicating the identification code associated with the user to the transmitting device, wherein the transmitting device transmits the identification code associated with the user;
the user moving to a second location with the transmitting device, the second location being within the area;
one of more of the receiving devices receiving the identification code transmitted by the transmitting device;
the one or more receiving devices sending details of the received identification code to the user location determining device; and
the user location determining device determining the location of the user, using the received details from the one or more receiving devices.
2. A user location system for determining the location of a user in an area, comprising:
a transmitter providing device located at a first location, the transmitter providing device further comprising a store of a plurality of transmitting devices, wherein the transmitter providing device generates a magnetic field that is above a predetermined threshold at locations within the store of transmitting devices, and the transmitting devices are arranged to transmit an identification code only when not within a magnetic field that is above the predetermined threshold;
a plurality of receiving devices distributed in different locations within the area; and
a user location determining device in communication with the plurality of receiving devices;
wherein the transmitter providing device is arranged, in response to a request from a user for a transmitting device, to associate an identification code with the user, and to provide the user with a transmitting device and to communicate the identification code associated with the user to the transmitting device;
wherein the transmitting device is arranged to transmit the identification code associated with the user;
wherein the plurality of receiving devices are arranged to receive the identification code transmitted by the transmitting device, and to send details of a received identification code to the user location determining device;
and wherein the user location determining device is arranged to determine the location of a user using received details from the one or more receiving devices.
