Touchless gesture recognition for elevator service

1. A method for provisioning elevator service, the method comprising:

sensing, by a gesture interface comprising a sensor, a region in proximity to the gesture interface to obtain data;

receiving, by the gesture interface, an identifier associated with the particular user;

determining, by the gesture interface, that a first pattern in the data corresponds to a first gesture based on a comparison of the data to a library of reference gestures, wherein the library of reference gestures comprises a plurality of reference gestures associated with the particular user; and

initiating a request for elevator service in response to determining that the first pattern corresponds to the first gesture.

2. The method of claim 1 , wherein when the first gesture corresponds to an upward motion the request for elevator service corresponds to a request for an elevator car traveling in an upward direction, or wherein when the first gesture corresponds to a downward motion the request for elevator service corresponds to a request for an elevator car traveling in a downward direction.

3. The method of claim 1 , wherein the identifier is based on at least one of: a mobile device

identifier, a radio-frequency identification (RFID) tag, and a facial recognition technique.

4. The method of claim 1 , further comprising:

determining, by the gesture interface, that a second pattern in the data corresponds to a second gesture.

5. The method of claim 4 , further comprising:

initiating, by the gesture interface, at least one door of an elevator car to be controlled based on the second gesture.

6. The method of claim 5 , further comprising:

initiating, by the gesture interface, the at least one door to be at least one of:

opened,

closed, and

stopped in terms of motion of the at least one door.

7. The method of claim 4 , further comprising:

initiating, by the gesture interface, the request for elevator service to be canceled based on the second gesture.

8. A method for provisioning elevator service, the method comprising:

sensing, by a gesture interface comprising a sensor, a region in proximity to the gesture interface to obtain data;

determining, by the gesture interface, that a first pattern in the data corresponds to a first gesture; and

initiating a request for elevator service in response to determining that the first pattern corresponds to the first gesture;

wherein a field of view associated with the sensor is representative to a height of a building in which the elevator system is located, and wherein a destination floor associated with the request for elevator service is selected based on a relative height of a user's hand in connection with the first gesture.

9. An apparatus comprising:

at least one processor; and

memory having instructions stored thereon that, when executed by the at least one processor, cause the apparatus to:

sense a region in proximity to the apparatus to obtain data;

receive an identifier associated with a particular user;

determine that a first pattern in the data corresponds to a first gesture based on a comparison of the data to a library of reference gestures, wherein the library of reference gestures comprises a plurality of reference gestures associated with the particular user; and

initiate a request for elevator service in response to determining that the first pattern corresponds to the first gesture.

10. The apparatus of claim 9 , wherein when the first gesture corresponds to an upward motion the request for elevator service corresponds to a request for an elevator car traveling in an upward direction, and wherein when the first gesture corresponds to a downward motion the request for elevator service corresponds to a request for an elevator car traveling in a downward direction.

11. The apparatus of claim 9 , wherein the instructions, when executed, cause the apparatus to:

determine that a second pattern in the data corresponds to a second gesture.

12. The apparatus of claim 11 , wherein the instructions, when executed, cause the apparatus to:

cause at least one door of an elevator car to be controlled based on the second gesture.

13. The apparatus of claim 12 , wherein the instructions, when executed, cause the apparatus to:

cause the at least one door to be at least one of:

opened,

closed, and

stopped in terms of motion of the at least one door.

14. The apparatus of claim 12 , wherein the second gesture corresponds to a side-to-side sweeping motion that serves to open the at least one door when oriented in a first direction and close the at least one door when oriented in a second direction that is substantially opposite to the first direction.

15. The apparatus of claim 12 , wherein the at least one door comprises two doors arranged as center-opening doors, and wherein the second gesture corresponds to at least one of:

a bringing together or joining of a user's hands to close the two doors, and

a separation of a user's hands to open the two doors.

16. A conveyance system, comprising:

a gesture interface configured to:

obtain data corresponding a region in proximity to the conveyance system by sensing the region;

receive an identifier associated with a particular user;

analyze the data to recognize when patterns in the data correspond to one or more gestures within a threshold based on a comparison of the data to a library of reference gestures, wherein the library of reference gestures comprises a plurality of reference gestures associated with the particular user, the one or more gestures comprising a request for service;

generate a command in response to analyzing the data; and

a controller configured to manage one or more resources associated with the conveyance system in response to the command.

17. The conveyance system of claim 16 , wherein the conveyance system comprises an elevator system, and wherein the one or more gestures comprise an indication of a number corresponding to a destination dispatch request.
