Head tracking cameras resolution - what difference does it make?

[imacken]

In practical terms, what difference does the res of a head tracking camera make?

With the PS3 Eye, for example, I cannot see the difference between running at 640x480 @ 60fps, and 320x240 @ 120fps. Nor do I see the difference with TrackIR at 640x480 @120fps.

I also cant see a difference between resolutions, but I do find the tracking smoother with higher Hz. So, I run my ps3 at 320x240, 120 Hz.

Me too, but TrackIR always boasts about achieivng 120fps @ 640x480, but I can't see what different that makes. Feels and looks the same to me in 320x240 @ 120fps as it does 640x480 @ 120fps.

:) well ... that's marketing at its best: it doesn't matter if a feature benefits the user or not, higher specs are a must for attracting buyers ... it reminds me of the curved screen TV's
