Thank you.

I caught this on the news yesterday. Replacing a steadicam with a headicam is going to make the images all herky-jerky, and eyes naturally dart all over a scene/object/person in order to analyze it. Consider what it does with just a webpage:

(even if the eye is artificial, the muscles controlling it should be subject to the same twitches and misdirections as the opposite "good" eye)
