The present invention provides improved methods and systems for assisting a user when interacting with a graphical user interface by combining gaze based input with gesture based user commands. The present invention provide systems, devices and method that enable a user of a computer system without a traditional touch-screen to interact with graphical user interfaces in a touch-screen like manner using a combination of gaze based input and gesture based user commands. Furthermore, the present invention offers a solution for touch-screen like interaction using gaze input and gesture based input as a complement or an alternative to touch-screen interactions with a computer device having a touch-screen, such as for instance in situations where interaction with the regular touch-screen is cumbersome or ergonomically challenging. Further, the present invention provides systems, devices and methods for combined gaze and gesture based interaction with graphical user interfaces 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.

System for gaze interaction

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.

Rotation of visual content on a display unit

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 touch-screen 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.

A control module for generating gesture based commands during user interaction with an information presentation area is provided. The control module is configured to acquire user input from a touchpad and gaze data signals from a gaze tracking module; and determine at least one user generated gesture based control command based on a user removing contact of a finger of the user with the touchpad; determine a gaze point area on the information presentation area including the user's gaze point based on at least the gaze data signals; and execute at least one user action manipulating a view presented on the graphical information presentation area based on the determined gaze point area and at least one user generated gesture based control command, wherein the user action is executed at said determined gaze point area.
