Abstract
A system has short-range transmission devices, each of which corresponds to a range of zones in a three dimensional space. The short-range devices are positioned at various locations within the three dimensional space and periodically broadcast signals. The zones are determined according to a plurality of signal characteristics sensed by client devices proximate to the short-range beacon transmission devices. In addition, the zones are assigned definitions.
Claims28
A method for determining a plurality of zones in a predetermined area associated with a system including a server, a plurality of transponders and a plurality of client devices configured to communicate with the server, the method comprising at least one client device:
- sensing at least one signal characteristic from at least one transponder of the plurality of transponders;
- determining proximity between the client device and the at least one transponder based on the signal characteristics;
- and
- mapping the determined proximity to at least one zone.
A method for determining a plurality of zones in a predetermined area associated with a system including a server, a plurality of transponders and a plurality of client devices configured to communicate with the server, the method comprising the server:
- receiving, from at least one of the client device, a plurality of sensed signal characteristics, derived from signals broadcast by the plurality of transponders;
- determining respective proximities between the at least one client device and the plurality of transponders according to the sensed signal characteristics;
- and
- mapping the proximity determinations to at least one zone.
A method for determining a plurality of zones in a predetermined area associated with a system including a server, multiple transponders and multiple client devices configured to communicate with the server, the steps including:
- communicating a plurality of sensed signal characteristics among the server, the multiple transponders and the multiple client devices;
- determining the plurality of zones corresponding to the plurality of sensed signal characteristics;
- and
- assigning a respective plurality of definitions to the plurality of zones.
A method for automatically estimating a plurality of zones in a predetermined area associated with a system including a server, multiple transponders and at least one client device configured to communicate with the server, the method including:
- sensing at least one signal characteristic associated with at least one of the multiple transponders and the at least one client device;
- processing a current context of the at least one client device;
- combining the current context and the at least one signal characteristic;
- and
- estimating the plurality of zones corresponding to the at least one transponder and the at least one client device.
