Abstract: According to the invention, an image sensor is disclosed. The image sensor may include a plurality of pixels. Each pixel of a first portion of the plurality of pixels may include a near-infrared filter configured to block red, green, and blue light; and pass near-infrared light. Each pixel of a second portion of the plurality of pixels may be configured to receive at least one of red, green, or blue light; and receive near-infrared light.

Abstract: An imaging device adapted to provide eye-tracking data by imaging at least one eye of a viewer, wherein: the imaging device is switchable between at least an active mode and a ready mode; the imaging device is configured to use active eye illumination in the active mode, which enables tracking of a corneal reflection; and the imaging device is configured, in the ready mode, to reduce an illumination intensity from a value the illumination intensity has in the active mode, and to provide eye-tracking data which include eye position but not eye orientation.
Abstract translation: 一种成像装置，适于通过对观看者的至少一只眼睛进行成像来提供眼睛跟踪数据，其中：所述成像装置可在至少活动模式和就绪模式之间切换; 成像装置被配置为在活动模式中使用主动眼睛照明，其使得能够跟踪角膜反射; 并且成像装置在准备模式下被配置为从照明强度在活动模式中具有的值减小照明强度，并且提供包括眼睛位置而不是眼睛定向的眼睛跟踪数据。

Abstract: The disclosure relates to an eye tracking device for tracking movements of an eye comprising, a viewing plane for displaying a projection of an image to the eye of a user, an image module placed on a same side of the viewing plane as the eye, at least one illuminator for illuminating the eye, a control unit adapted to receive an image captured by the image module, and calculate a viewing angle of the eye, a holographic optical element (HOE), wherein a HOE is placed between the eye and the viewing plane, wherein the image module is adapted to capture an image of the HOE, and wherein the HOE is adapted to direct at last a first portion of incident light reflected from the eye, in a first angle towards the image module, the first angle being different from an angle of the incidence of the incident light

Abstract: A system for determining a gaze direction of a user of a wearable device is disclosed. The system may include a primary lens, an illuminator, an image sensor, and an interface. The illuminator may include a light guide, may be disposed at least partially on or in the primary lens, and may be configured to illuminate at least one eye of a user. The image sensor may be disposed on or in the primary lens, and may be configured to detect light reflected by the at least one eye of the user. The interface may be configured to provide data from the image sensor to a processor for determining a gaze direction of the user based at least in part on light detected by the image sensor.

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.
