Abstract: A gaze tracking system, leaving a low power mode in response to an activation signal, captures an initial burst of eye pictures in short time by restricting the image area of a sensor, with the purpose of enabling an increased frame rate. Subsequent eye pictures are captured at normal frame rate. The first gaze point value is computed memorylessly based on the initial burst of eye pictures and no additional imagery, while subsequent values may be computed recursively by taking into account previous gaze point values or information from previous eye pictures. The restriction of the image area may be guided by a preliminary overview picture captured using the same or a different sensor. From the gaze point values, the system may derive a control signal to be supplied to a computer device with a visual display.

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.

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.

Abstract: A subject (180) is illuminated whose movements of at least one eye are to be registered by an eye-tracker for producing resulting data (DEYE). To this aim, a coherent light source in light producing means (140) produces at least one well-defined light beam (L1, L2). A diffractive optical element is arranged between the coherent light source and an output from the light producing means (140). The diffractive optical element is configured to direct a light beam (L1) towards at least a first designated area (A1) estimated to cover the at least one eye of the subject (180). Image registering means (150) registers light from the at least one light beam (L1, L2) having been reflected against the subject (180). The resulting data (DEYE) are produced in response to these light reflections, which resulting data (DEYE) represent movements of the at least one eye of the subject (180).
