(Link to YouTube) Expert pianist Daniel Beliavsky and his student Charlotte Bennett analyze eye-tracking footage taken while they perform, both from memory and from sheet music.
The more experienced pianist knows where the keys are and where his hands are, but he's thinking and looking ahead of the notes he's playing, and his gaze position is generally more stable.
I'd love to see what this technology, called Tobii Pro Spectrum, could tell us about how a visual artist sees the world.
As wonderful as it is, however, the limitation of such an eye-scanning device is that it can only track the center of the gaze. It can't account for peripheral vision. Without much changing gaze direction, experienced artists are able to widen their peripheral attention to see overall relationships or to focus the attention on small details.
Learning when and how to do that is one of the things art students must master.
