Beacon-based electronic guide system

An electronic guide system, comprising:

• a movable beacon that (1) determines a current location of the movable beacon to obtain descriptive information of each of a plurality of landmarks associated with the current location, and (2) transmits electronic signals containing the descriptive information of each of the landmarks;
• a client device physically separated from the beacon to receive the electronic signals containing the descriptive information of each of the landmarks when placed by a user within a transmission range of the beacon;
• a relative location sensor that determines relative location of the client device with respect to the movable beacon to cause the client device to selectively provide the user with the descriptive information of some of the landmarks based on the relative location of the client device.

An electronic guide system, comprising:

• a movable beacon that (1) determines a current location of the movable beacon to obtain descriptive information of each of a plurality of landmarks associated with the current location, (2) selects the descriptive information of some of the landmarks based on a relative location of a physical point with respect to the movable beacon, and transmits electronic signals containing the descriptive information of the some of the landmarks;
• a client device that receives the electronic signals containing the descriptive information of the some of the landmarks when the client device is at the relative location of the physical point.
