  • Publication number: 20150042477
    Abstract: A monitoring system and method for monitoring and/or predicting drowsiness of a driver of a vehicle or a machinery operator are provided. A set of infrared, IR, or near infrared, NIR, light sources, is arranged such that an amount of the light emitted from the light source incidents on an eye of the driver or operator. The light that impinges on the eye of the driver or operator forms a virtual image of the signal sources on the eye including the sclera and/or cornea. An image sensor obtains consecutive images capturing the reflected light, wherein each image will contain glints from at least a subset or all of the light sources. A drowsiness index can be determined based on the extracted information of the glints of the sequence of images, wherein the drowsiness index indicates a degree of drowsiness of the driver or operator.

  • Patent number: 8342687
    Abstract: Provided is a method of determining a gaze point of an eye watching a visual display controllable by a display signal. The method comprises generating a display signal using a graphics card in order for the visual display to produce a screen pattern; receiving a signal encoding an image of the eye including a corneo-scleral reflection of the screen pattern; and determining, based on in part the geometry of said reflection, a gaze point of the eye, wherein said determining a gaze point includes utilizing the graphics card as a parallel processor. The image of the eye may be received directly at the graphics card. The graphics card may extract image features in the eye images. Reference illuminators may be used, and the screen pattern may be interlaced with a distinctive reference pattern. Further provided are a gaze-tracking system and a personal computer system adapted to determine a gaze point of a viewer.

  • Patent number: 8314707
    Abstract: A monitoring system monitors and/or predicts drowsiness of a driver of a vehicle or a machine operator. A set of infrared or near infrared light sources is arranged such that an amount of the light emitted from the light source strikes an eye of the driver or operator. The light that impinges on the eye of the driver or operator forms a virtual image of the signal sources on the eye, including the sclera and/or cornea. An image sensor obtains consecutive images capturing the reflected light. Each image contains glints from at least a subset or from all of the light sources. A drowsiness index can be determined based on the extracted information of the glints of the sequence of images. The drowsiness index indicates a degree of drowsiness of the driver or operator.
