Abstract: The visual search test makes it possible to establish a parameter for binocular coordination that is useful for detecting an oculomotor abnormality, in particular in the context of detecting dyslexia. A system for assisting in the detection is also described.

Abstract: An optical system (100) for following ocular movements of an individual includes: an acquisition module (190) designed so as to acquire an image (Im) of the two eyes (22, 22d, 22g) of the individual, an optical element of transmission (110d, 110g), to the acquisition module, of two images (lm_d, lm_g) of respectively each eye which together correspond to a discontinuous region (24d, 24g) of the face, by multiple reflections along two optical routes (TOd, TOg) devoid of any semireflecting mirror. The optical routes further include optical input paths (114d, 114g) opposite respectively each eye, which are parallel to one another and to an optical axis (Z) of the acquisition module, and the optical element of transmission is configured so as to bring the two images closer together so that the acquisition module acquires the two images simultaneously.

Abstract: A system for detecting a functional area (102) in the brain (104) of a person that causes hemispatial neglect in the person in the event of a lesion, includes: at least one electrode (106) for inducing a stimulus at a position of the brain (104) of the person; elements (108) for displaying a geometrical shape (112) after the stimulus; selection elements (110) for enabling the person to designate, according to predetermined instructions, a position relative to the geometrical shape (112); elements (108) for detecting the designated position; elements (116) for comparing the designated position with a position calculated according to the instructions; and elements (118, 120) for transmitting a signal on the basis of the comparison.

Abstract: System for demonstrating oculomotor abnormalities in a eukaryote, the system including: —elements for capturing (13) the eye movements made by the eukaryote while the eukaryote is stimulated with at least one image in accordance with at least one instruction, wherein the capture elements (13, 14) supply a capture signal, —an analysis module (18) for calculating the value of at least one predetermined parameter by analysis of the capture signal, and —elements (22) for determining an abnormality as a function of the calculated value at least one predetermined value for each of the parameters.
