A communication method implemented in an environment of an elevator communication system inside a building is intended to realize a communication between a first terminal corresponding to a visitor and a second terminal corresponding to a to-be-visited target object inside the building, and the communication method includes the steps of: determining the to-be-visited target object by the first terminal from the elevator communication system; initiating, via the elevator communication system, a request to establish communication with the second terminal by the first terminal; accepting the request by the second terminal, and transmitting its second indoor positioning information to the first terminal by the second terminal via the elevator communication system; and presenting the second indoor positioning information by the first terminal.

A method of reassigning an elevator call for an elevator car comprising: receiving an elevator call from a mobile device, the elevator call including a destination request to travel from a boarding floor to a destination floor; assigning a first elevator car to the elevator call; activating an alert on the mobile device that the first elevator car has been assigned to the elevator call; determining that the first elevator car cannot serve the elevator call; assigning a second elevator car to the elevator call; and activating an alert on the mobile device indicating that the second elevator car has been assigned to the elevator call.

A method of operating an elevator call control system including: receiving an first elevator call from a first individual carrying a first mobile device, the first elevator call including a destination request to travel from a first boarding floor to a destination floor; assigning a first elevator car to the first elevator call; detecting a location of the first mobile device; detecting a location of a second mobile device; and determining that a second individual carrying the second mobile device intends to board the first elevator car with the first individual carrying the first mobile device in response to determining the location of the first mobile device and the location of the second mobile device.

According to an aspect, a method of priority-based adjustment to display content is provided. The method includes determining a position of a first observer relative to a display device and determining a position of a second observer relative to the display device. A first content screen associated with the first observer is displayed on the display device based on determining that the first observer has a greater display priority than the second observer based at least in part on the position of the first observer and the position of the second observer. A second content screen associated with the second observer is displayed on the display device based on determining that the second observer has a greater display priority than the first observer based at least in part on the position of the first observer and the position of the second observer.

Disclosed is an elevator system in a building for transporting a passenger with a mobile device between a plurality of levels including a first level having lobby, the system comprising an elevator including an accessibility implement, and a controller that communicates with the elevator and the mobile device, the controller configured to render a plurality of determinations including: a first determination that the passenger requires service from an elevator with an accessibility implement, a second determination that the elevator includes an accessibility implement and is available to service the passenger, and the controller configured to transmit instructions to the elevator whereby the elevator effects the second determination.

Disclosed is an elevator system for a building, the system including a first elevator for transporting a passenger with a first mobile device between a plurality of lobbies, the system comprising a controller that communicates with the first mobile device renders a plurality of determinations including: a first determination that the passenger is seeking to engage a tenant, whom is a building tenant, a second determination to provide directional information between a current location of the passenger and a first lobby on the first level, a third determination to assign the first elevator to transport the passenger from the first lobby to a second lobby on the second level to engage the tenant, the controller being configured to effect a plurality of transmissions including: a first transmission to the first mobile device to effect the second determination, and a second transmission to the first elevator to effect the third determination.

A method is provided for displaying information in an elevator arrangement including an elevator car that is movable, as controlled by an operating panel, between landing zones that communicate traffic to and from the elevator car through a doorway, and one or more light sources. In the method, visible objects are defined for guiding traffic of the elevator arrangement. A destination landing zone is obtained by the operating panel. A current occupancy and current destination landing zone of the elevator car are determined. The light sources are set to illuminate at least one of the defined visible objects on a remote surface on the basis of the determined current occupancy and current destination landing zone of the elevator car and the destination landing zone obtained by the operating panel.

An elevator controller according to the present disclosure includes: a communication unit that receives, from a mobile terminal, signals each including information about elevator halls; and a determination unit that makes a determination for guiding a user on a basis of the information about the elevator halls received by the communication unit. The communication unit receives, from the mobile terminal, a first signal including floor registration elevator hall information, and after that, receives, from the mobile terminal, a second signal including registered floor return elevator hall information. On a basis of the first signal and the second signal, the determination unit determines whether or not an elevator at a registered floor return elevator hall is an elevator that goes to a floor registration elevator hall and, when the elevator is the elevator that goes to the floor registration elevator hall, notifies the mobile terminal the determination result.

According to an aspect, a method includes receiving a passenger request to reserve an elevator car of an elevator system to travel to a targeted destination. At least two different travel options to the targeted destination are determined based on a plurality of elevator car travel plans comprising at least two elevator cars having different travel ranges. The at least two different travel options are output to an interactive display. At least one of the at least two elevator cars is reserved responsive to a user selection of one of the at least two different travel options.

A system to determine a location of a signal emitting device is provided. First, second, and third data is received from at least one movable communication device. Each of the first, second, and third data include a unique identifier of the signal emitting device, a signal strength of a signal received by the at least one movable communication device from the signal emitting device, and a location of the at least one movable communication device when it received the signal. Each of the first, second, and third data include different locations of the at least one movable communication device. A location of the signal emitting device is computed based at least in part on the received first, second, and third data.
