Elevator operator interface with virtual activation
First Claim
1. An elevator activation system, wherein the elevator activation system comprises:
- a. a plurality of buttons positioned on an operating panel and configured to be activated by physical contact, wherein the plurality of buttons are positioned along multiple horizontal and vertical axes;
b. an optical sensing device, wherein the optical sensing device is configured to project an optical curtain, wherein the optical curtain comprises an array that covers the plurality of buttons that are positioned along the multiple horizontal and vertical axes of the operating panel, wherein the optical sensing device is configured to detect a disturbance in the optical curtain at a distance away from the operating panel; and
c. a sensor controller, wherein the sensor controller is configured to virtually activate at least one button of the plurality of buttons in response to the disturbance detected in the optical curtain, wherein virtual activation of the at least one button of the plurality of buttons comprises activation of the at least one button before physically contacting the operating panel.

Abstract
An elevator activation system provides virtual activation of one or more buttons by passengers. An optical sensor or time-of-flight camera is positioned near buttons of the elevator and projects an optical curtain over buttons of the elevator. Disturbances in the optical curtain are detected and an exact location of a disturbance in the optical curtain is communicated to a sensor controller which then virtually activates a button correlated to the particular location of the disturbance. The sensor controller communicates with an elevator controller such that the elevator is controlled based on the particular function activated in response to virtual activation of the button. The elevator activation system may further include a user feedback feature configured to signify to a passenger that a button has been virtually activated without physically contacting the button.

16. A method for controlling an elevator comprising the steps of:
-
a. projecting an optical curtain from an optical sensing device, wherein the optical curtain is projected over a plurality of physically activatable buttons oriented along multiple axes within an operating panel; b. sensing at the optical sensing device, a disturbance in the optical curtain from a precise location within the optical curtain, wherein the disturbance in the optical curtain is sensed at a predetermined distance away from the plurality of physically activatable buttons such that the disturbance is sensed before physically contacting the operating panel, c. virtually activating a first button of the plurality of physically activatable buttons in response to the optical sensing device sensing the disturbance at the precise location within the optical curtain; and d. controlling a predetermined function of the elevator in response to virtual activation of the first button. - View Dependent Claims (17)
