Abstract

Elevator car systems including a primary car operating panel fixedly located on an elevator car panel and a secondary car operating panel display system. The Display system includes a detection and tracking device configured to detect the entry and location of passengers within the elevator car and a display device configured to display a secondary car operating panel at a location proximate to a detected and tracked passenger.

First claim

What is claimed is:

1. An elevator car comprising:
a primary car operating panel fixedly located on an elevator car panel; and
a secondary car operating panel display system comprising:
a detection and tracking device configured to detect the entry and location of passengers within the elevator car;
a display device configured to display a secondary car operating panel at a location proximate to a detected and tracked passenger; and
a secondary car operating panel controller operably connected to the detection and tracking device and the display device,
wherein the secondary car operating panel controller is configured to receive input from the detection and tracking device, control the display device to display the secondary car operating panel at a specific location, and receive input from the display device in response to the display device detecting a passenger input.

2. The elevator car of claim 1 , wherein the secondary car operating panel controller is configured to not display a secondary car operating panel if at least one of (i) the detected and tracked passenger is located within a predetermined distance from the primary car operating panel, (ii) an input is received at the primary car operating panel within a predetermined time from a time of detection of the passenger, or (iii) a display time expires without receiving an input at the secondary car operating panel.

3. The elevator car of claim 1 , wherein the display device and the detection and tracking device are housed as a single unit.

4. The elevator car of claim 1 , wherein the display device is at least one of an image projector, a touch screen, or a holographic projector.

5. The elevator car of claim 1 , wherein the detection and tracking device includes at least one of an optical sensor, an infrared sensor, a camera, a proximity sensor, a floor sensor, a pressure sensor, an acoustic sensor, or a motion sensor.

6. A method for operating an elevator car having a primary car operating panel, the method comprising:
detecting entry of a passenger into the elevator car with a detection and tracking device;
tracking the position of the passenger within the elevator car with the detection and tracking device; and
displaying a secondary car operating panel proximate to the detected and tracked passenger,
wherein, prior to displaying the secondary car operating panel, at least one of (i) determining the position of the passenger relative to the primary car operating panel, (ii) determining a timing of an input at the primary car operating panel, or (iii) starting a display timer.

7. The method of claim 6 , wherein at least one of (i) the secondary car operating panel is not displayed when the position of the passenger is within a predetermined distance from the primary car operating panel or (ii) the display of secondary car operating panel is stopped at the expiration of the display timer.

8. The method of claim 6 , wherein when the input at the primary car operating panel occurs within a predetermined time of detecting entry of the passenger the secondary car operating panel is not displayed.

9. The method of claim 6 , wherein the secondary car operating panel is displayed using at least one of an image projector, a touch screen, or a holographic projector.

10. The method of claim 6 , wherein the detection and tracking includes use of at least one of an optical sensor, an infrared sensor, a camera, a proximity sensor, a floor sensor, a pressure sensor, an acoustic sensor, or a motion sensor.

11. The method of claim 6 , further comprising detecting a passenger input at the secondary car operating panel.

12. The method of claim 11 , further comprising controlling the elevator car in response to the passenger input.

13. The method of claim 11 , further comprising indicating on the primary car operating panel information related to the passenger input.
