The method of interactive quantification of digitized 3D objects using an eye tracking camera is based on that a) coordinates of observed screen space are determined using a camera that senses the position of pupils of the operator gazing on the screen; b) dimensions of studied sub-volume of VOI block of dimensions of Sx, Sy, Sz or VOI cylinder of dimensions of Sx = Sy = Sxy are defined; c) analyzed particle and VOI position is selected; d) VOI is visualized, where its individual levels are displayed side by side on the screen; e) observed space is corrected by VOI visualization, where the observed level is highlighted by a bold box; f) the last level is selected by gaze of the operator from the sequence of probe levels and the gaze is focused on the last level on which the particle is still visible, and level identification is confirmed by gaze fixation for a certain period of tíme; g) the particle is analyzed by algorithm to verify the property of the marked particle in 3D space, and the particle is marked with a color mark, while the mark position on levels between the marked levels is determined by interpolation or by finding a representative point by analyzing real image data.
