Cameras are common accessories for mobile (cell) phones and Bluetooth wireless connections are also seen more and more. In the future, the camera lens will be mounted on the wireless headphone and both still pictures and video will be taken from the user’s point of view. The screen on the camera will show the current camera view but it won’t be used that often as people just snap or record “what they see” for future reference.
Initial control will be from the headphone or phone body but soon verbal commands (just say “snap”) will control the camera.
