Abstract

Elevator systems having an elevator car having a first elevator car door and an audio orientation system. The audio orientation system includes an audio system controller, at least one first speaker positioned proximate the first elevator car door, and at least one second speaker positioned in the elevator car opposite the first elevator car door. When the first elevator car door opens, the audio system controller controls the at least one first speaker and the at least one second speaker such that an audio orientation output is generated at at least one of the speakers to indicate that the first elevator car door is open.

First claim

What is claimed is:

1. An elevator system comprising:
an elevator car having a first elevator car door; and
an audio orientation system, the audio orientation system comprising:
an audio system controller;
at least one first speaker positioned proximate the first elevator car door;
at least one second speaker positioned in the elevator car opposite the first elevator car door; and
at least one detector arranged to detect the presence of a sight impaired user, the at least one detector in communication with the audio system controller such that the audio orientation system is activated when the at least one detector detects the presence of the sight impaired user,

wherein, when the first elevator car door opens, the audio system controller controls the at least one first speaker and the at least one second speaker such that an audio orientation output is generated at at least one of the speakers to indicate that the first elevator car door is open, and
wherein the at least one detector is configured to detect a user device of the sight impaired user.

2. The elevator system of claim 1 , wherein, when a request is made at a landing of the elevator system and when the first elevator car door opens, the audio system controller controls the at least one second speaker to generate an audio orientation output indicating that the first elevator car door is open.

3. The elevator system of claim 1 , wherein, when a request is made within the elevator car to travel to a landing of the elevator system and when the first elevator car door opens, the audio system controller controls the at least one first speaker to generate an audio orientation output indicating that the first elevator car door is open.

4. The elevator system of claim 1 , wherein the elevator car comprises a second elevator car door opposite the first elevator door and wherein the at least one second speaker is positioned proximate the second elevator car door.

5. The elevator system of claim 4 , wherein, when the second elevator car door opens, the audio system controller controls the at least one first speaker and the at least one second speaker such that an audio orientation output is generated at at least one of the speakers to indicate that the second elevator car door is open.

6. The elevator system of claim 5 , wherein, when a request is made at a landing of the elevator system and when the second elevator car door opens, the audio system controller controls the at least one first speaker to generate an audio orientation output indicating that the second elevator car door is open.

7. The elevator system of claim 5 , wherein, when a request is made within the elevator car to travel to a landing of the elevator system and when the second elevator car door opens, the audio system controller controls the at least one second speaker to generate an audio orientation output indicating that the second elevator car door is open.

8. The elevator system of claim 1 , wherein the audio orientation system comprises four speakers and the elevator comprises four corners, wherein a speaker is positioned in each of the corners.

9. The elevator system of claim 1 , wherein the user device is at least one of a smartphone, an RFID device, and a Bluetooth enabled device.

10. A method of operating an elevator system, wherein the elevator system includes an elevator car having a first elevator car door, an audio system controller, at least one first speaker positioned adjacent the first elevator car door, and at least one second speaker positioned in the elevator car opposite the first elevator car door, the method comprising:
detecting an opening of the first elevator car door at a landing of the elevator system;
detecting a user device of a passenger, wherein the user device indicates that the passenger is a sight impaired user; and
generating an audio orientation output from at least one of the first speakers or second speakers, wherein the audio orientation output indicates the opening of the first elevator car door.

11. The method of claim 10 , further comprising detecting a request made at a landing of the elevator system, wherein the audio orientation output is generated at the at least one second speaker and indicates that the first elevator car door is open.

12. The method of claim 10 , further comprising detecting a request made at a car operating panel within the elevator car, wherein the audio orientation output is generated at the at least one first speaker and indicates that the first elevator car door is open.

13. The method of claim 10 , the elevator car comprising a second elevator car door opposite the first elevator car door and the at least one second speaker is positioned adjacent the second elevator car door, the method further comprising detecting a request made at a landing of the elevator system, wherein the audio orientation output is generated at the at least one first speaker and indicates that the second elevator car door is open.

14. The method of claim 10 , the elevator car comprising a second elevator car door opposite the first elevator car door and the at least one second speaker is positioned adjacent the second elevator car door, the method further comprising detecting a request made at a car operating panel within the elevator car, wherein the audio orientation output is generated at the at least one second speaker and indicates that the second elevator car door is open.
