1. A vehicle entertainment system, comprising:
- a display device;
at least one gesture control camera configured to generate a camera signal responsive to light reflected from at least one object within a field of view of the at least one gesture control camera; and
a processor configured to;
analyze the camera signal to identify a gesture made by a passenger moving the at least one object,control at least one operation of the vehicle entertainment system responsive to the identified gesture,respond to an indication that the passenger has becoming seated in a seat facing the display device by performing an initial calibration to identify a distance to the passenger'"'"'s body and identify locations of at least one object in the foreground between the passenger'"'"'s body and the at least one gesture control camera, anddetermine when the passenger'"'"'s body has moved at least a threshold distance away from or toward the at least one gesture control camera while remaining seated, and respond to the determination by performing a calibration to identify a distance to the passenger'"'"'s body and identify locations of at least one object in the foreground between the passenger'"'"'s body and the at least one gesture control camera.

Abstract
A vehicle entertainment system is controlled responsive to gestures that are formed by a passenger of the vehicle. The vehicle entertainment system includes a display device, at least one gesture control camera, and a processor. The gesture control camera generates a camera signal responsive to light reflected from at least one object within a field of view of the at least one gesture control camera. The processor analyzes the camera signal to identify a gesture made by a passenger moving the at least one object, and controls at least one operation of the vehicle entertainment system responsive to the identified gesture.

11. A vehicle entertainment system, comprising:
-
a display device; at least one gesture control camera configured to generate a camera signal responsive to light reflected from at least one object within a field of view of the at least one gesture control camera; an acceleration sensor that outputs an acceleration signal that indicates a level of acceleration of the vehicle entertainment system; and a processor configured to; analyze the camera signal to identify a gesture made by a passenger moving the at least one object, control at least one operation of the vehicle entertainment system responsive to the identified gesture, and use the acceleration signal to at least partially compensate for effect of acceleration on the at least one object moved by the passenger when identifying the gesture made by the passenger, by identifying presence of turbulence in response to the acceleration signal indicating at least a threshold level of acceleration; and increasing a distance that the passenger needs to move the at least one object to generate a gesture that is identified by the processor, responsive to identifying the presence of turbulence. - View Dependent Claims (12)

13. A vehicle entertainment system, comprising:
-
a display device; a pair of gesture control cameras each configured to generate a camera signal responsive to light reflected from at least one object within a field of view of the gesture control camera, the pair of gesture control cameras are spaced apart from each other and tilted toward each other to provide a narrowed overlapping field of view in front of the display device for sensing the at least one object moved by a passenger when identifying a gesture made by the passenger; and a processor configured to; analyze the camera signals from the pair of gesture control cameras to identify a gesture made by the passenger moving the at least one object, control at least one operation of the vehicle entertainment system responsive to the identified gesture, and ignore movement that occurs within the field of view of only one, but not both, of the pair of gesture control cameras when identifying the gesture made by the passenger. - View Dependent Claims (14)

17. A vehicle entertainment system, comprising:
-
a display device; a pair of gesture control cameras each configured to generate a camera signal responsive to light reflected from at least one object within a field of view of the gesture control camera, the pair of gesture control cameras are spaced apart from each other; and a processor configured to; analyze the camera signals from the pair of gesture control cameras to identify a gesture made by a passenger moving the at least one object, control at least one operation of the vehicle entertainment system responsive to the identified gesture, and determine distance between the at least one object and the pair of gesture control camera, to ignore object movement that occurs within the field of view of only one but not both of the gesture control cameras when identifying a gesture made by the passenger, and to further ignore object movement that is beyond a threshold distance of the gesture control cameras although being within the field of view of both of the gesture control cameras when identifying a gesture made by the passenger.
