Abstract: The disclosure relates to a vision device for detecting eye movement, which comprises a screen for displaying stimuli, an LCD panel for selectively blocking the viewing by either eye of the stimuli displayed on the screen, the panel being capable of adopting a number of configurations, including a configuration blocking the vision of either eye and a configuration allowing the vision of either eye, and at least one camera for tracking eye movement in wavelengths outside the visible spectrum through the panel. The camera being capable of tracking the movement of the eyes under the effect of the stimuli in the configurations of the panel that allow vision and block vision.

Abstract: The disclosure relates to a system for measuring reactions of a subject, comprising: a screen able to display a plurality of stimuli via a refresh of pixels of the screen, the stimuli being apt to generate reactions from the subject; at least one sensor able to capture images of the subject reacting to the stimuli; and a logic unit configured to command the refresh of the pixels of the screen at a first frequency and the capture of the images of the subject by the sensor at a second frequency, one of the frequencies being an integer multiple of the other frequency. The logic unit also comprises a central clock configured to command the refresh of pixels of the screen and the capture of the images. The disclosure also relates to a method for measuring reactions of a subject, to a computer program and to a computer-readable medium.
