Abstract
The invention describes a method of performing a gaze-based interaction between a user (1) and an interactive display system (2) comprising a three-dimensional display area (D) in which a number of physical objects (10, 11, 12, 13, 14, 15, 16) is arranged, and an observation means (3), which method comprises the steps of acquiring a gaze-related output (30) for the user (1) from the observation means (3), determining a momentary gaze category (Go, Gdw, Gbo, Gnr) from a plurality of gaze categories (Go, Gdw, Gbo, Gnr) on the basis of the gaze-related output (30); and continuously generating display area feedback according to the momentary determined gaze category (Go, Gdw, Gbo, Gnr). The invention further describes an interactive display system (2) comprising a three-dimensional display area (D) in which a number of physical objects (10, 11, 12, 13, 14, 15, 16) is arranged, an observation means (3) for acquiring a gaze-related output (30) for a user (1), a gaze category determination unit (22) for determining a momentary gaze category (Go, Gdw, Gbo, Gnr) from a plurality of gaze categories (Go, Gdw, Gbo, Gnr) on the basis of the gaze-related output (30); and a feedback generation unit (25) for continuously generating display area feedback (29) according to the momentary determined gaze category (Go, Gdw, Gbo, Gnr).

15. A method of performing a gaze-based interaction between a user and an interactive display system comprising a three-dimensional display area in which a number of physical objects is arranged, and an observation means, the method comprising the steps of:
-
acquiring a gaze-related output for the user by the observation means; translating the gaze-related output into a gaze heading for the user based on a gaze direction of the user derived from the gaze-related output; determining a momentary gaze category from a plurality of gaze categories based on the gaze-related output, wherein the momentary gaze category is selected from the group consisting of a first gaze category when the gaze heading is directed at an object in the display area for less than a predefined dwell-time; a second gaze category when the gaze heading is directed at an object in the display area for at least a predefined dwell-time; a third gaze category when the gaze heading is directed between objects in the display area; and continuously generating display area feedback according to the momentary determined gaze category. - View Dependent Claims (16, 17, 18, 19, 20)
