HOTSPOTS FOR EYE TRACK CONTROL OF IMAGE MANIPULATION
First Claim
1. An eye-tracking interaction system (2) for controlling adjustment of digital image parameters, the eye-tracking interaction system comprising:
- a display (5) for presenting a digital image (50) to a user (1), the image having a region of interest (ROI) (21) in which image parameters are to be adjusted;
an eye-tracking system (3, 4) for determining a fixation point (8) of a user'"'"'s eyes on the display;
means (6, 7) for visually outlining areas (24) defining two or more hotspots (25, 26, 27, 28, 29, 30) on the display in relation to the ROI, wherein;
the hotspots are arranged within a region (20, 40, 42, 44, 52) bordering and at least partly encircling the ROI and allowing a user to have at least part of the ROI in focus when the fixation point of the user'"'"'s eyes is within a hotspot, the region being defined by inner diameter d and outer diameter D and D is larger than d (D>
d);
the hotspots occupy different angular sections of the region;
each hotspot is associated with a given adjustment of a given image parameter;
means (6, 7) for performing adjustment of an image parameter associated with a hotspot when the fixation point of a user'"'"'s eyes falls within the hotspot, the associated image parameter adjustment being performed at least in the ROI;
means (6, 7) for providing feedback to the user by highlighting a hotspot when its associated image parameter adjustment is performed.

Abstract
The invention relates to a system for manipulating images or graphics where the manipulation to be performed are selected or activated using eye-tracking. A number of hotspots are arranged around and bordering a region of interest (ROI), which are each, associated with an image parameter adjustment (e.g. contrast or brightness). An eye-tracking device determines a fixation point of the user and the system automatically performs the associated adjustment whenever the fixation point falls within a hotspot. The close bordering of the hotspots around the ROI allows the user to keep focus on the ROI and only slightly shift his/her gaze to or towards a hotspot for adjusting an image parameter. Thereby, the adjustment can be controlled while still keeping the ROI in focus so that the effect of the adjustment can be followed simultaneously.
