  • Patent number: 9971170
    Abstract: A device for controlling a lens for adjustable vision correction is provided. The device, e.g., a smartphone, comprises circuits to determine if a user of the device is gazing at the device, and, if the user is gazing at the device, to determine a distance between the eye and the device, and to control the lens to adjust its focal length based on the determined distance. Thereby, the lens is adjusted only if required, i.e., if the user is gazing at the device. The circuits may be suitable for correcting presbyopia if the user is gazing at a device located at close distance, and alleviate the need for the user to actively operate a switch or move her head for adjusting the focal length of her lenses.

    Abstract: A system and method of detecting eye movements of a subject for the diagnosis of neurological disorders. The method includes tracking eye movements of the subject, identifying microsaccades from the tracked eye movements, and characterizing microsaccade dynamics of the identified microsaccades to determine one or more parameters, such as microsaccade direction, microsaccade velocity, microsaccade magnitude, microsaccadic peak velocity-magnitude relationship, microsaccade duration, and infersaccatic intervals. The method also includes comparing the one or more determined parameters with a corresponding control parameter, assessing the comparison to determine differences between the one or more determined parameters and the corresponding control parameters, and generating a report including the diagnosis of neurological disorder based on the assessment.

  • Patent number: 9952672
    Abstract: A computer apparatus is associated with a graphical display presenting at least one GUI-component adapted to be manipulated based on user-generated commands. An event engine is adapted to receive an eye-tracking data signal that describes a user's point of regard on the display. Based on the signal, the event engine produces a set of non-cursor controlling event output signals, which influence the at least one GUI-component. Each non-cursor controlling event output signal describes a particular aspect of the user's ocular activity in respect of the display. Initially, the event engine receives a control signal request from each of the at least one GUI-component. The control signal request defines a sub-set of the set of non-cursor controlling event output signals which is required by the particular GUI-component. The event engine delivers non-cursor controlling event output signals to the at least one GUI-component in accordance with each respective control signal request.

In order for the user to be authenticated, an image is captured of the user while the user is within an interaction zone, which is an area that is within both a field of view of the camera and a suitable distance range from the camera. If the user is not within the suitable distance range from the camera, then feedback is provided indicating that the user is not within the suitable distance range from the camera. Various feedback can be provided, such as one or a combination of audio, visual, and haptic feedback.

  • Patent number: 9658453
    Abstract: An apparatus comprising a diffractive combiner having a front side, a rear surface, and an optical axis running substantially through the center of the diffractive combiner and normal to the back side. A display unit directs display light toward the back side of the diffractive combiner; the display unit positioned at a first angle relative to the optical axis, and the display light having a first range of wavelengths. An eye-tracking sensor receives eye-tracking radiation reflected by the back side of the diffractive combiner, the eye-tracking sensor positioned next to the display unit at a second angle relative to the optical axis, the second angle being different than the first angle and the eye-tracking radiation having a wavelength outside the first range of wavelengths.

  • Patent number: 9622654
    Abstract: A device for corneal imaging is disclosed. The device comprises a first camera and processing means. The first camera is configured for imaging a cornea of a user of the device and/or an eyewear worn by the user. The processing means is operative to acquire a first image from the first camera, identify a first reflection by the cornea and/or a second reflection by a reflective surface of the eyewear, and determine a first optical transformation representing the first reflection and/or a second optical transformation representing the second reflection. Embodiments of the invention provide an improved corneal imaging solution for user operated computing devices by taking specular reflections originating from one or more reflective surfaces of an eyewear worn by the user into consideration. Also disclosed are a corresponding method, computer program, and computer program product.

  • Patent number: 9594500
    Abstract: A touch free toilet control panel display which may be used, for activating various components of a smart toilet. The user may touch freely use a touch free input device, for choosing from a displayed menu of toilet functions. Various input devices may used to activate the displayed toilet devices, such as, a floating capacitive field (404) to detect a user's fingers hovering above the displayed menu options (406), body movement recognition used to control the movement of a displayed cursor, an eye tracking system (604), that uses the user's gaze point (610), tongue recognition, etc. Touch free activation of the menu functions, reduces the transmission of bacteria from the menu panel to the user, and may also ease the use of the toilet devices. The display menu may show toilet devices, such as, a bidet, bidet water temperature, internet connection, etc. Other embodiments are described and shown.
