Subject: does anyone know this number?
I remember reading somewhere, that during natural vision (i.e. without head
restraint) humans rarely move their eyeballs more than x degrees within
their sockets (sorry, I realise I'm probably not using the correct terms
here). After this amount, we are more likely to move our whole head, in
order to look at something. I can not find the original reference to this
number - I seem to recall it was between 5 and 8 degrees. If anyone can
assist, by telling me what this figure should be, I would be very grateful
Thank you
Ruth Conroy
