Go problems experiments
March 2000:
The main economic newspaper in Japan, the Nihon Keizai Shinbun (sponsors of the Oza) recently reported (2000-01-01) a unique experiment at the NTT Communications Science Foundation Research Laboratory in Atsugi City, Kanagawa Prefecture. Using an eye camera, researchers tested amateurs from dan strength down to beginners with a series of go problems.
They were trying to find the most important factors in solving them by tracking the eye movements and the line of vision until the problem was solved. They found that strong players locked on to the solution within 0.6 seconds on average, but with beginners the eyes made virtually unfocused movements.
Perhaps more interestingly, in the case of whole-board problems, the high-dan players focused on empty areas of the board, whereas the beginners spent a lot of time with their gaze fixed on the lines of stones. There are indications that the results could be translated into improved software to train players to solve problems faster.
