CLAIMS

What is claimed is:

1. A virtual control system comprising:

a control unit,

a gesture recognition device, and

a hologram generation device,

wherein the hologram generation device is configured to generate a hologram in a first volume of space, wherein the gesture recognition device is configured to recognize a proper gesture within the first volume of space, and wherein the control unit is configured to send a signal to a component to be controlled when the gesture recognition device recognizes the proper gesture.

2. The virtual control system of claim 1 further comprising an acoustic field generator, wherein the acoustic field generator is configured to generate an acoustic field in a second volume of space, wherein the first volume of space and second volume of space at least partially overlap to form a virtual control volume, wherein the gesture recognition device is configured to recognize the proper gesture within the virtual control volume.

3. The virtual control system of claim 2 wherein the virtual control system is associated with an aircraft lavatory, and wherein the hologram is one of a knob, a button, a lever or a switch.

4. The virtual control system of claim 3 wherein the hologram is generated in a location adjacent the component to be controlled.

5. The virtual control system of claim 4 further comprising a motion sensor, wherein the hologram is generated when the motion sensor senses motion.

6. A method of switching a component to be controlled from a first state to a second state, the method comprising the steps of:

providing a virtual control system that includes a control unit, an acoustic field

generator, a gesture recognition device, and a hologram generation device, wherein the

hologram generation device is configured to generate a hologram in a first volume of

space, wherein the acoustic field generator is configured to generate an acoustic field in a

second volume of space, wherein the first volume of space and second volume of space at

least partially overlap to form a virtual control volume, wherein the gesture recognition

device is configured to recognize a human motion or gesture within the virtual control

volume,

proj ecting a hologram in the first volume of space,

generating an acoustic field in the second volume of space,

sending a signal to the control unit when the gesture recognition device recognizes a proper gesture within the virtual control volume, and

sending a signal from the control unit to the component to be controlled and switching the component to be controlled from the first state to the second state.

7. The method of claim 6 wherein the virtual control system is associated with an aircraft lavatory, and wherein the hologram is one of a knob, a button, a lever or a switch.

8. An aircraft lavatory comprising:

an enclosure that defines a lavatory interior,

a door that is movable between an open and a closed position,

a sink positioned in the lavatory interior,

a toilet positioned in the lavatory interior,

a virtual control system, that includes a control unit, a gesture recognition device, and a hologram generation device, wherein the hologram generation device is configured to generate a hologram in a first volume of space within the lavatory interior, wherein the gesture recognition device is configured to recognize a proper gesture within the first volume of space, wherein the control unit is configured to send a signal to a component to be controlled when the gesture recognition device recognizes the proper gesture, and wherein the component to be controlled is associated with one of the toilet, sink or door.

9. The aircraft lavatory of claim 8 further comprising an acoustic field generator, wherein the acoustic field generator is configured to generate an acoustic field in a second volume of space within the lavatory interior, wherein the first volume of space and second volume of space at least partially overlap to form a virtual control volume, wherein the gesture recognition device is configured to recognize the proper gesture within the virtual control volume.

10. The aircraft lavatory of claim 8 wherein the hologram is configured to be generated when the door is moved from the closed position to the open position.

11. The aircraft lavatory of claim 8 further comprising a motion sensor, wherein the hologram is generated when the motion sensor is activated.
