Locating the primary attention focus of the user
First, a signal detection experiment was carried out to estimate the maximal distance between the primary attention focus of users and the screen position of visual feedback (e.g. messages). The results indicate that the maximal distance between the primary attention focus and the position of visual feedback should not exceed 3. Second, to pinpoint the location of the primary attention focus we carried out an eye movement recording experiment. The results indicate that if the task solving process requires mouse operations and the visual feedback of the results of these mouse operations appears close to the mouse cursor, then the visual focus and the mouse cursor position on the screen are highly correlated: between 76% and 95% correspondence.
