发明名称 Beacon-based electronic guide system
摘要 An electronic guide system is described that includes a fixed-location beacon located adjacent to a location which is associated with a plurality of landmarks to transmit electronic signals containing descriptive information of each of the landmarks. The guide system also includes 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 viewing direction sensor is provided to determine viewing direction of the user to cause the client device to provide the user with the descriptive information of one of the landmarks at which the user is looking. An electronic guide system that includes a movable beacon is also described.
