Professional pianist and Steinway Artist Daniel Beliavsky and his student Charlotte Bennett agreed to perform while hooked up to an eye-tracking device that superimposes the wearer's eye movements.
The sight-reading exercise yields the most interesting results. They do some comparative statistical analysis at the end, and as expected, Daniel does not look at the keys as much as his student Charlotte, and he keeps his eyes in a narrower area of the piano keys when he does look.
It would be great to see the footage stabilized! They suggest this is the first in a series, so subscribe for future installments.
