Abstract: A passenger detector (10) for use in a passenger conveyor system (12) is provided that includes a structured light source (34), a structured light detector (36), and a controller (38). The structured light source (34) is operable to project light (40) into a detection area (32) in a predetermined projected pattern. The structured light detector (36) is operable to generate reflected light signals indicative of light (40) reflected back toward the structured light detector (36) from the detection area (32). The controller (38) is operable to receive the reflected light signals from the structured light detector (36), and operable to process the reflected light signals to make a determination as to whether a passenger is disposed within a detection area (32).

Abstract: A system and method for user localization and acoustic voice interface are provided. The system including a locator system that includes at least one sensor that detects a location of a user and generates a location value, a listening system that includes a microphone array that includes at least one microphone, wherein the listening system receives the location value and collects an audio signal from the location defined by the location value, and a signal processor that generates a control signal based on at least the audio signal.

Abstract: A method and intent recognition system that triggers voice recognition is provided. The intent recognition system includes an intent recognition device that detects a user location and/or behavior in a building and detects a triggering event based on the user location and/or behavior that suggests the user wants to input a service request, a prompt device that is triggered to provide a prompt based on the detecting by the intent recognition device and the detected triggering event, a listening device that receives an auditory input from the user, a signal processing device that processes the received auditory input and generates a control signal, and in-building equipment that receives the control signal from the signal processing device and controls the in-building equipment based on the control signal.
