Abstract

The invention relates to a system comprising an oculometer for measuring movements of at least one eye of an operator, wherein it comprises furthermore a display for displaying, for the eye, a frame of at least one point performing a blinking, so that the operator can perform at least one smooth tracking movement of the eye while looking at the display while operating. The invention also relates to a method implemented on such a system, and a corresponding computer program product.

Claims

1. A system comprising an oculometer for measuring movements of at least one eye of the operator,

wherein it also comprises a display for displaying, for the eye, a frame of at least one point performing a blinking, so that the operator can carry out at least one smooth tracking motion of the eye while looking at the display in operation.

2. The system according to claim 1, wherein the display

comprises at least one sensor of coordinates of a projection of a direction of a gaze of the eye onto the display, and

is designed to display a reference point in the frame, the position of the reference point on the display depending on the coordinates of the projection of the direction of the gaze of the eye into the display.

3. The system according to claim 1, comprising a unit for processing the movements of the eye of the operator, for generating:

at least one graphic, and/or

at least one letter, and/or

at least one numeral, and/or

at least one sound, and/or

at least one command.

4. The system according to claim 3, wherein the oculometer is designed to also measure a diameter of the pupil of the eye of the operator, the unit being designed to modulate the graphic and/or the letter and/or the numeral and/or the sound and/or the command depending on the diameter of the pupil of the eye of the operator.

5. The system according to claim 1, also comprising an interface allowing adjustment of the contrast and/or the blinking frequency of the frame.

6. A method comprising a step in which an oculometer measures movements of at least one eye of the operator,

wherein it also comprises a step wherein a display displays, for the eye, a frame of at least one point performing blinking, such that the operator can carry out at least one smooth tracking motion of the eye while looking at the display in operation.

7. The method according to claim 6, comprising a step wherein at least one sensor of the display measures coordinates of a projection of a direction of a gaze of the eye onto the display,

and wherein the display displays a reference point in the frame, the position of the reference point on the display depending on the coordinates of the projection of the direction of the gaze of the eye onto the display.

8. The method according to claim 6, comprising a step wherein a unit for processing movements of the eye of the operator generates:

at least one graphic, and/or

at least one letter, and/or

at least one sound, and/or

at least one command.

9. The method according to claim 8, comprising a step wherein the oculometer also measures a diameter of a pupil of the eye of the operator, and wherein the unit modulates the graphic and/or the letter, and/or the sound and/or the command depending on the diameter of the pupil of the eye of the operator.

10. A computer program product comprising instructions which, once loaded into a memory of a computer, allow the implementation of a method according to claim 6.
