[visionlist] Looking for recommendations for eye trackers.

[John Pezaris]

Are you looking to track adult humans, children, or monkeys?  The last
time I checked, which was about a year ago, the support for monkeys
was pending on these devices.

I have had mixed results using an earlier version of their bar
trackers with NHP, after being told they would work.

Perhaps our needs are unusual, but I've found that manufacturer
specifications are optimistic by about an order of magnitude in terms
of accuracy at the shortest latencies, because of noise.  Averaging to
reduce that noise will, of course, reduce the effective frame rate,
and often the specs do not reflect the fact that the values given are
after heavy averaging.
