    Abstract: Disclosed is a driver condition detecting device and a driver condition informing device detecting inattentive or incursive driving by movements of a head and eyeball of a driver during driving. The CPU, when the head and the eyeball of the driver are determined as not facing forward, and neither the vestibule oculogyral reflex movement nor the semicircular carnal cervix reflex movement is detected, determines and informs the inattentive driving. The CPU, even though the head and the eyeball of the driver are determined as facing forward, detects an angle-of-convergence, and determines and informs the inattentive driving when the angle-of-convergence lies above a threshold.

  • Publication number: 20150097938
    Abstract: A method and an apparatus for recording reading behavior are provided. A movement trajectory of a user's eye is tracked based on an eye-tracking procedure, so as to calculate reading time of a gazing part of an electronic document when it is detected that sight of an eye leaves the gazing part, or when it is detected that the eye keeps gazing the electronic document and reading of the gazing part is finished. And the reading time is recorded to a storage space corresponding to the gazing part.

  • Publication number: 20150100493
    Abstract: A method of iris scanning and proximity sensing, which includes receiving and photographing an iris in the iris scanning mode of the subject computer, laptop, mobile device or tablet, smartphone or i-phone; sensing for the available amount of necessary light and whether the iris is within the desired range to ensure proper acquisition of the sample. The iris is then photographed. The method provides for recognizing the iris utilizing the previously photographed iris image and converting the photographed iris image to an encrypted mathematical value, which will then be stored within the acquiring electronic device such as computer, laptop, smartphone; i-phone; mobile device or tablet, to be compared for future reference against any subject photographed iris. If any subsequently photographed iris matches the encrypted mathematical stored image, access to the device is granted. If the subsequently photographed iris does not match the encrypted mathematical stored image, access is denied.

  • Patent number: 8996097
    Abstract: In an ophthalmic measuring method, a traceable marker in particulate form is administered to the lachrymal fluid of a subject's eye, and the lachrymal fluid is irradiated with illuminating light. Images of the illuminated lachrymal fluid are electronically captured respectively at different times. Two images from among the captured images are selected, with each of the two selected images displaying the traceable marker. A characteristic point of each of the two selected images is specified. A movement speed of the traceable marker is measured based on positions thereof in the two selected images and on a time difference from specifying the characteristic point of one of the two selected images to specifying the characteristic point of the other of the two selected images. The measured movement speed of the traceable marker is outputted as the movement speed of the lachrymal fluid of the subject's eye.

    Abstract: Exemplary embodiments provide a tracking optics system for mobile devices. The tracking optics system may comprise a telescope longitudinally disposed in a case of the mobile device, wherein a length of the telescope is greater than a depth of the mobile device; an illuminator that emits a light source and low-power mode through the telescope towards a target of image capture; a two-axis gimbal mirror that is adjusted to steer the light source towards the target until the target is within a field of view of the telescope; and an image sensor that captures an image of the target in response to the illuminator emitting the light source in high power mode to flash the target.
