Abstract

The disclosure relates to controlling and manipulating an image of an object on a display device based on tracked eye movements of an observer. When the object is displayed according to an initial view, the observer's eye movement is tracked and processed in order to determine the focus of the observer's attention or gaze on the image. Thereafter, the displayed image is modified to provide a better view of the part of the object in which the observer is most interested. This is accomplished by modifying at least one of the spatial positioning of the object within the viewing area, the angle of view of the object, and the viewing direction of the object.

Description

Technical field [0001] The present disclosure relates to image processing methods, systems and computer programs. Background technique [0002] Many computer applications use computer graphics to display images of objects to users. For example, computer graphics can be used in applications to display computer-generated models of actual objects (for example, houses or cars). Similarly, it is possible to model and display more abstract objects in computer applications (for example, a spherical world map). These objects can be defined in a two-dimensional space, or they can be defined as a three-dimensional model, which is then rendered on a two-dimensional viewing area (such as a computer screen). [0003] In addition, the computer application may provide a user interface that allows the user to modify the view of the object in the displayed image in order to provide a better viewing experience. The user interface may include certain input devices such as a mouse or a keyboard, wh...
