Abstract: A computerized method, system for, and computer-readable medium operable to: determine a set of coordinates corresponding to a user's gaze; determine a user interface (UI) element corresponding to the set of coordinates; return that UI element as being detected and again repeating the determination of the set of coordinates corresponding to the user's gaze; determine if the UI element being returned is the same for a predetermined threshold of time according to a started timer; if the UI element is not the same, reset the started timer and again repeating the determination of the set of coordinates corresponding to the user's gaze; and if the UI element is the same, making the UI element active without requiring any additional action from the user and currently selecting the UI element to receive input.

Abstract: The present invention includes a method for analyzing an image wherein elements defining a path within a two-dimensional image are received from a prescreener. A Sobel operator may be applied to the region around each of the elements of the chain to obtain a corresponding array of gradient directions. An angle correction may be applied to any of the gradient directions that goes beyond the highest value (in radian measure; the Pi ?Pi transition), to obtain an array of gradient directions free of any artificial jumps in value. The gradient direction array (Sobel chaincode) can have its bandwidth taken to determine a single number of straightness so as to identify extremely straight edges, (manmade objects) from less straight edges (natural objects). A similar process can be used to analyze contours for straight sections, which are also parallel. These two and other filters applied to the gradient array can be part of a feature suite, for feature space analysis.
