Abstract

A system and method for providing directional information to a user using existing infrastructure elements (150) is disclosed. The method comprising determining a route of infrastructure elements (150) between a current location and a remote location, wherein the current location is associated a first element in the route and the last element in the route being closest to the remote location, wherein each of the elements in the route are identified by at least one of: a physical identification and a data identification, and providing a visual indication, progressively, to each of the infrastructure elements in the route at a predetermined time and for a determined period, wherein the progressive display of the visual indication provides for direction control information.

Claims

1. A system for providing directional information comprising:

a plurality of infrastructure elements arranged in at least one network configuration, said infrastructure elements having at least one of a physical location identification and a data identification;

an interface connected to each of the plurality of infrastructure elements, said interface including at least one of;

an input device and a visual output device;

a central controller, in communication with said infrastructure elements, responsive to a input received from an input device associated with one of said plurality of infrastructure elements regarding a remote location,

assigns a visual indicator to the input received,

determines a route of selected ones of said plurality of infrastructure elements between a position associated with the input device providing the input received and an infrastructure element close to the remote location, wherein the selected ones of said plurality of infrastructure elements are generally adjacent infrastructure elements; and

provides the assigned visual indicator progressively to each of the selected ones of said plurality of infrastructure elements in the route at a predetermined time for a predetermined period; and

wherein the predetermined time is based on a walking speed interval to a next one of said selected infrastructure elements in the route, wherein the walking speed is initially set to a predetermined walking speed and thereafter an average walking speed interval is dynamically determined, based on actual walking speeds of previous walking speed intervals.

2. The system of claim 1, wherein the input device further comprises:

means for providing at least one predetermined remote location.

3. The system of claim 2, wherein the central controller:

determines a route to one of said at least one predetermined remote location; and

causes said lighting element associated with said infrastructure elements to progressively light along said route at a predetermined time for a predetermined period.

4. The system of claim 3, wherein said predetermined time and said predetermined period are selected to provide the illusion of motion.

5. The system of claim 1, wherein each of the infrastructure elements has a physical address.

6. The system of claim 1, wherein each of the infrastructure elements includes a GPS receiver.

7. The system of claim 1, wherein the step of determining the route comprises:

determining a geographical difference between the positions associated with the input device providing the input received and the remote location;

determining an infrastructure element closest to said remote location; and

determining each infrastructure element between the infrastructure element associated with input device providing the input received and the infrastructure element closest to the remote location, wherein each infrastructure element is identified by at least a corresponding physical identification or data identification.

8. The system of claim 1, wherein the input device includes wireless communication protocols.

9. The system of claim 8, wherein the input device is one of:

Bluetooth, Near Field Communication, and cellular communication.

10. The system of claim 1, wherein said infrastructure element is at least one of:

a streetlamp including a lighting element, a telephone pole including a lighting element, and an indoor lighting system including a plurality of lighting elements.

11. The system of claim 10, wherein the lighting elements are turned on and turned off at a pre-determined rate to provide the visual indicator.

12. The system of claim 11, wherein the lighting elements associated with said infrastructure elements are repeatedly operated.

13. A method for providing directional control comprising:

in a controller,

receiving, a remote location from a current location;

determining a route from said current location to said remote location, wherein said route is determined from selected ones of a plurality of infrastructure elements arranged in a network of infrastructure elements, said current location being associated with an infrastructure element first in said determined route and a last infrastructure element being associated with an infrastructure element closest to said remote location;

providing a visual indication, progressively, on each of said selected infrastructure elements, wherein said visual indication is progressively provided on a next infrastructure element in said route at a predetermined time and for a determined period; and

wherein the predetermined time is based on a walking speed interval to a next one of said selected infrastructure elements in the route, wherein the walking speed is initially set to a predetermined walking speed and thereafter an average walking speed interval is dynamically determined, based on actual walking speeds of previous walking speed intervals.

14. The method of claim 13, wherein the visual indication is provided by one of:

a lamp associated with a corresponding one of the plurality of infrastructure elements, a lighting system, and a display associated with a corresponding one of the plurality of infrastructure elements.

15. The method of claim 13, wherein each of said plurality of infrastructure elements is identified by at least one of:

a physical network identification and a data network identification.

16. The method of claim 13, wherein the visual indication is flashed at a current infrastructure element at a known rate.

17. The method of claim 13, wherein the progressive display of said visual indication is selected to provide an illusion of motion of said visual indication.
