摘要： At least one image registering unit records at least one series of images representing a subject. A control unit controls an operation sequence for the at least one image registering unit in such a manner that a subsequent data processing unit receives a repeating sequence of image frames there from, wherein each period contains at least one image frame of a first resolution and at least one image frame of a second resolution being different from the first resolution. Based on the registered image frames, the data processing unit produces eye/gaze tracking data with respect to the subject.

摘要： An image sensing apparatus has a light sensitive area and a control unit. The light sensitive area registers image data in response to an incoming amount of light, and is operable in an active mode wherein image data can be read out there from as well as in a standby mode wherein image data cannot be read out. The control unit produces a control signal setting the light sensitive area to operate in the active mode and the standby mode respectively in a cyclic manner during an operation period, which preferably encompasses multiple data frame read-outs of image data from the light sensitive area.

摘要： The invention generally relates to computer implemented systems and methods for utilizing detection of eye movements in connection with interactive graphical user interfaces and, in particular, for utilizing eye tracking data to facilitate and improve information search and presentation in connection with interactive graphical user interfaces. A gaze search index is determined based on information that has been presented on an information presentation area and gaze data signals. The gaze search index comprises links between gaze search parameters and presented information that satisfies gaze filter criteria for respective gaze search parameter. A user can initiate query searches for information on the computer device or on information hosts connectable to the computer device via networks by using combinations of gaze search parameters of the gaze search index and non gaze search parameters of a non gaze search index.

摘要： A graphics presentation apparatus including a display unit, an eye-tracking module, and a data output module. The eye-tracking module registers image data representing at least one eye of a user of the apparatus. Furthermore, the eye-tracking module determines, based on the registered image data, an orientation of the at least one eye relative to the display unit. Finally, in response thereto, the eye-tracking module generates a control signal controlling the data output module to produce visual content with such orientation on the display unit that a misalignment between the orientation of said at least one part and the orientation of the at least one eye of the user is minimized.

摘要： A method and system for assisting a user when interacting with a graphical user interface combines gaze based input with gesture based user commands. A user of a computer system without a traditional touch-screen can interact with graphical user interfaces in a touch-screen like manner using a combination of gaze based input and gesture based user commands. A solution for touch-screen like interaction uses gaze input and gesture based input as a complement or an alternative to touch-screen interactions with a computer device having a touch-screen. Combined gaze and gesture based interaction with graphical user interfaces can be used to achieve a touchscreen like environment in computer systems without a traditional touchscreen or in computer systems having a touchscreen arranged ergonomically unfavourable for the user or a touchscreen arranged such that it is more comfortable for the user to use gesture and gaze for the interaction than the touchscreen.

摘要： 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.
