Abstract:
1. A method implemented on an electronic book reader device, the method comprising: presenting a user interface (UI) with one or more navigational elements on a display of the electronic book reader device, the UI having a movable pointer to allow user selection of the navigational elements; defining a gravitational region corresponding to individual navigational elements, the gravitational region providing a visual effect to attract the pointer to the gravitational region as the pointer is moved across the corresponding navigational element; receiving user-controlled movement of the pointer within the UI; monitoring a trajectory of the pointer as the pointer is moved over the navigational elements; determining whether the pointer is decelerating within a particular gravitational region, wherein determining whether the pointer is decelerating within the particular gravitational region comprises determining whether the pointer is decelerating within a predetermined distance relative to the gravitational region; and responsive to determining the deceleration, repositioning the pointer to another location within the gravitational region.
