Handsfree Elevator Control System

Abstract

A touchless interface device utilizing a plurality of infrared beams is disclosed along with its method of use. By using beams of light to detect the position of a user's hand, the touchless elevator call button selection device allows the user to interface with the elevator control system without physically coming into contact with the elevator control system.

What is claimed is: 
     
         1 . A touchless interface device, for use with an elevator call button system, the elevator call button system having at least one of call button, the device comprising:
 a sensor module comprising at least one sensor, each sensor having;
 an emitter configured to outwardly emit at least one infrared beam; and 
 a receiver,
 wherein a variable indexing point is determined by an interruption in any of the at least one infrared beams; and 
 
   a sensor control system comprising a control board, the control board having a first memory and a first processor;
 wherein the first memory is configured to receive and store an electronic file containing a spatial configuration of the at least one of call button, 
 wherein the first memory contains computer-readable instructions for implementing a mapping scheme correlating the spatial configuration to the variable indexing point of the at least one sensor, 
 wherein the first processor is configured to execute the contents of the first memory. 
   
     
     
         2 . The device of  claim 1 , further comprising a sensor housing which envelops the sensor module. 
     
     
         3 . The device of  claim 1 , wherein each of the at least one of sensor are proximate to at least one of the other plurality of sensors, wherein the plurality of sensors are disposed in the sensor module in a linear manner creating a line in a first direction, wherein the at least one infrared beam of each emitter is outwardly emitted in a second direction, wherein the first direction and the second direction are non-parallel, and wherein the plurality of sensors are in electronic communication. 
     
     
         4 . The device of  claim 1 , wherein the sensor control system is in electronic communication with the elevator call button system. 
     
     
         5 . The device of  claim 4 , wherein the sensor control system is in direct electronic communication with the elevator call button system. 
     
     
         6 . The device of  claim 1 , wherein the control board receives power directly from the elevator call button system.
