Image manipulation based on tracked eye movement

摘要

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.

1. A method, comprising:
obtaining a data point of a tracked eye gaze at a predetermined sampling interval of a displayed image of an object in a viewing area, the data point representing a detected location of the tracked eye gaze within the viewing area; determining a range of the viewing area in which the data point is located; magnifying the displayed image when the determined range is smaller than a first predetermined range; and shrinking the displayed image when the determined range is larger than a second predetermined range.
