Patent ID: 11353953

Abstract:
A method of modifying an image on a computational device is disclosed. The method comprises providing image data representative of at least a portion of a three-dimensional scene, the scene being visible to a human observer from a viewing point when fixating on a visual fixation point within the scene; displaying an image by rendering the image data on a display device; capturing user input by user input capturing means, wherein capturing comprises monitoring a point of gaze of a user so as to determine a spatial coordinate in the three dimensional scene, the coordinate representing a movable visual fixation point of the human observer; computationally processing the image data so as to enclose each object of the three dimensional scene in a three dimensional detection region which is configured to identify coincidence of the respective object with the visual fixation point; modifying the image by: computationally isolating a fixation region within the image, the fixation region being defined by a subset of image data representing an image object within the image, wherein the image object is associated with the visual fixation point; spatially reconstructing the subset of image data to computationally expand the fixation region; spatially reconstructing remaining image data relative to the subset of image data to computationally compress a peripheral region of the image relative to the fixation region in a progressive fashion as a function of a distance from the fixation region, the method further comprising determining a distance between a head of the user and the display device; computationally processing the image data so as to move the fixation region towards a centre of a display of the display device, wherein the fixation region represents the object enclosed by the respective detection region; wherein the computational expansion of the fixation region and the computational compression of the peripheral region are modulated by the distance between the head of the user and the display device.
