ABSTRACT

Over the past 20 years I have seen dramatic changes in the interest in eye movements. There are now about 500 researchers looking at eye movements world wide. Some want to develop the ultimate recording device that is at once accurate, precise, and reliable, but by its very nature so restrictive that it is quite likely to provide recordings separate from anything that goes on in the real world, whatever that may be. Others want to develop a system that records unobtrusively to learn what really happens but, then because they can't nail the eyeball to a stationary object, tradeoff precision, and accuracy.
