Publication number: 20180242841Abstract: A subject is illuminated whose movements of at least one eye are to be registered by an eye-tracker for producing resulting data. To this aim, a coherent light source in light producing means produces at least one well-defined light beam. A diffractive optical element is arranged between the coherent light source and an output from the light producing means. The diffractive optical element is configured to direct a light beam towards at least a first designated area estimated to cover the at least one eye of the subject. Image registering means registers light from the at least one light beam having been reflected against the subject.

Publication number: 20180206771Abstract: 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.Type: ApplicationFiled: March 21, 2018Publication date: July 26, 2018Applicant: Tobii ABInventors: Miroslav Kobetski, Johnny Holmberg, Peter Blixt, John Mikael Elvesjö

Patent number: 10025389Abstract: 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.Type: GrantFiled: December 22, 2011Date of Patent: July 17, 2018Assignee: Tobii ABInventors: Christoffer Björklund, Henrik Eskilsson, Magnus Jacobson, Mårten Skogö

Patent number: 10013053Abstract: 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 unfavorable 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.Type: GrantFiled: October 5, 2012Date of Patent: July 3, 2018Assignee: Tobii ABInventors: Markus Cederlund, Robert Gavelin, Anders Vennström, Anders Kaplan, Anders Olsson, Mårten Skogö

Publication number: 20180181272Abstract: Disclosed are various embodiments for automatic scrolling of content displayed on a display device in response to gaze detection. Content may be displayed in a window rendered on a display screen. Gaze detection components may be used to detect that a user is gazing at the displayed content and to determine a gaze point relative to the display screen. At least one applicable scroll zone relative to the display screen and a scroll action associated with each applicable scroll zone may be determined. In response to determining that the gaze point is within a first applicable scroll zone, an associated first scroll action may be initiated. The first scroll action causes the content to scroll within the window until at least one of: expiration of a defined period, determining that a portion of the content scrolls past a defined position within the window, determining that the gaze point is outside of the first scroll zone, and detecting an indicator that the user begins reading the content.Type: ApplicationFiled: December 21, 2017Publication date: June 28, 2018Applicant: Tobii ABInventors: Anders Olsson, Mårten Skogö
