An　eye　movement　measurement　method　and　system;　　by　means　of　acquiring　the　current　focus　point　position　coordinates　x　i　and　y　i　and　the　next　focus　point　position　coordinates　x　i+1　and　y　i+1　during　the　process　of　eye　movement,　　said　method　calculates,　　on　the　basis　of　said　coordinate　values,　　the　eye　movement　vector　angle　θi,　　the　eye　movement　vector　amplitude　Di,　　the　horizontal　eye　movement　angle　θ＇i,　　and/or　the　eye　movement　slopeKi,　　and　can　thereby　accurately　and　comprehensively　indicate　the　direction　and　slope　degree　of　eye　movement,　　thus　providing　a　new　research　method　for　psychological　medicine　associated　with　eye　movement.
