Abstract
A gesture and location recognition system and method are provided. The system includes a sensor device that captures a data signal of a user and detects a gesture input from the user from the data signal, wherein a user location can be calculated based on a sensor location of the sensor device in a building and the collected data signal of the user, a signal processing device that generates a control signal based on the gesture input and the user location, 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.
Claims11
A gesture and location recognition system configured to support an elevator system, the gesture and location recognition system comprising:
- a plurality of sensor devices each disposed in a respective sensor location in a building remote from the elevator system, wherein each sensor device of the plurality of sensor devices are configured to capture a data signal associated with a gesture input performed by a user,
- wherein a user location is calculated based on the sensor location of the associated sensor device that captures the data signal and;
- a signal processing device in communication with the plurality of sensor devices, and configured to detect the gesture input from the data signal and generate an elevator call signal based on the gesture input and the user location, wherein
- the elevator system includes one or more elevator ears and one or more elevator controllers configured to receive the elevator call signal from the signal processing device and controls the one or more elevator cars based on the elevator call signal, and wherein the signal processing device estimates a travel time for the user to travel to an elevator lobby from the user location and adjusts the elevator call signal based on the estimated travel time to travel to the elevator lobby.
A method with gesture and location recognition, the method comprising:
- capturing, using a sensor device, a data signal representative of a gesture input performed by a user;
- detecting the gesture input from the data signal by a signal processing device,
- calculating a user location by the signal processing device, and based on a sensor location of the sensor device in a building and the captured data signal;
- generating, using the signal processing device, a control signal based on the gesture input and the user location;
- estimating, using the signal processing device, a travel time for the user to travel to an elevator lobby for boarding the elevator car from the user location;
- adjusting, using the signal processing device, the control signal based on the estimated travel time to travel to the elevator car, wherein the control signal is an elevator call signal;
- receiving the control signal by an elevator controller of an elevator system and from the signal processing device;
- and
- controlling an elevator car of the elevator system based on the control signal, wherein the sensor device is one of a network of sensor devices and the sensor location is one of a plurality of remote sensor locations with each sensor device located at a respective sensor location in a building containing the elevator system, and the plurality of remote locations are placed outside a normal interaction distance for calling the elevator car in an elevator lobby.
