Provided are an eye movement sensing method, a flexible contact body, and an external sensing coil and system. The method comprises: sensing, by using a following movement signal of a permanent magnet (11) planted in a flexible contact body (10) caused by an eye movement, the eye movement, the permanent magnet (11) being arranged at a periphery of a pupil area corresponding to the flexible contact body monitoring a following movement of the permanent magnet (11) by using at least four coils (21) provided externally on a same plane and according to electromotive forces in the coils (21), central lines of the four coils (21) being respectively located in four directions of plane coordinate axes, and two coils (21) on a same axis having opposite winding directions and being connected to each other in series and converting the electromotive forces and restore an eye movement signal. Sensing coils (21) distributed around an eye socket are used to detect an electromotive force generated from a following movement of a flexible contact body (20) caused by an eye movement, and the electromotive force is analyzed and thereby an eye movement triggered by a perceptive task is analyzed objectively.La présente invention concerne un procédé de détection de mouvements oculaires, un corps de contact flexible, ainsi quune bobine de détection externe et un système. Le procédé comprend : la détection, en utilisant un signal de mouvement de suivi dun aimant permanent (11) placé dans un corps de contact flexible (10) provoqué par un mouvement oculaire, du mouvement oculaire, laimant permanent (11) étant disposé au niveau dune périphérie dune zone de pupille correspondant au corps de contact flexible la surveillance dun mouvement de suivi de laimant permanent (11) en utilisant au moins quatre bobines (21) fournies à lextérieur sur le même plan et en fonction de forces électromotrices dans les bobines (21), les lignes centrales des quatre bobines (21) étant respectivement situées dans quat
