To provide an apparatus and method for analyzing eye fixation related potential which can evaluate attention concentration precisely by sorting a saccade by various kinds of states and calculating the eye fixation related potential.
Eye movement and a brain wave signal are measured, and occurrence of the saccade is determined based on the measured eye movement to detect a saccade size and a saccade finish time to extract the brain wave signal with the saccade finish time as a trigger. The saccade size is sorted into a state according to the saccade size. Then, the arithmetic mean of the extracted brain wave signals corresponding to each of sorted states is calculated to calculate the eye fixation related potential of each sorted state, and the average saccade size of each state is calculated based on the saccade size corresponding to each of the sorted states.
