Vision device for detecting eye movement
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.
1 . A vision device for detecting eye movement comprising:
a stimuli display screen;
an LCD panel for selectively blocking vision of one eye or the other eye of stimuli displayed on the stimuli display screen, wherein the LCD panel is able to be in several configurations, including a configuration blocking the vision of one eye or the other eye and a configuration allowing the vision of one eye or the other eye; and
at least one camera for tracking the movement of the eyes in wavelengths outside the visible spectrum through the LCD panel, wherein the at least one camera is able to track the movement of the eyes under an effect of the stimuli in the configurations of the LCD panel, allowing the vision and blocking the vision.
2 . The vision device according to claim 1 , wherein the wavelengths are those of infrared wavelengths.
3 . The vision device according to claim 2 , further comprising emitters for illuminating the LCD panel in the infrared wavelengths.
4 . The vision device according to claim 1 , wherein the LCD panel comprises at least one LCD area per eye.
5 . The vision device according to claim 1 , wherein:
the LCD panel is continuous for both eyes; and
the LCD panel comprises pixels selectively blocked for the vision of the one eye or the other eye.
6 . The vision device according to claim 1 , wherein:
the LCD panel comprises pixels associated with a colour filter; and
the pixels are selectively blocked.
7 . The vision device according to claim 1 , further comprising:
a vision cone with a chamber having a first end and a second end;
a processing unit at the first end of the chamber, the processing unit comprising the stimuli display screen for displaying stimuli and the at least one camera for tracking the eye movement; and
an opening at the second end of the chamber for the vision of the stimuli on the stimuli display screen,
the at least one camera being able to track the movement of the eyes through the LCD panel in configurations allowing the vision and blocking the vision.
8 . The vision device according to claim 7 , wherein the configuration of the LCD panel is controlled by the processing unit.
9 . The vision device according to claim 7 , wherein the LCD panel is removably positioned in the vision cone.
10 . The vision device according to claim 7 , the at least one camera is further configured to film both eyes.
11 . The vision device according to claim 7 , wherein the stimuli display screen provides backlighting for the LCD panel.
12 . A method for detecting eye movement, comprising:
providing a vision device, the vision device comprising:
a stimuli display screen;
an LCD panel for selectively blocking vision of one eye or the other eye of stimuli displayed on the stimuli display screen, the LCD panel being able to be in several configurations, including a configuration blocking the vision of one eye or the other eye and a configuration allowing the vision of one eye or the other eye; and
at least one camera for tracking the movement of the eyes in wavelengths outside the visible spectrum through the LCD panel;
displaying the stimuli on the stimuli display screen;
selectively blocking the vision of one eye or the other eye from the stimuli displayed on the stimuli display screen; and
tracking of the eye movement by the at least one camera in the wavelengths outside the visible spectrum through the LCD panel, wherein:
the at least one camera tracks the eye movement under an effect of the stimuli in configurations of the LCD panel; and
the tracking of the eye movement causes the allowing the vision of the one eye or the blocking the vision of the one eye.
13 . The method according to claim 12 , the vision device further comprising:
a vision cone with a chamber having a first end and a second end; and
a processing unit at one end of the chamber, wherein:
the processing unit comprises the stimuli display screen for displaying the stimuli and the at least one camera for the tracking the eye movement; and
the processing unit controls the display of the stimuli on the stimuli display screen and coordinates the display of the stimuli and the configuration of the LCD panel.
14 . The method according to claim 13 , further comprising recording scenarios in the processing unit that coordinates a display on the stimuli display screen and allows the vision and blocks the vision of each eye through the LCD panel.
15 . The method according to claim 12 , wherein the configurations of the LCD panel allowing the vision and blocking the vision are different for each eye.
