  • User control of the trade-off between rate of navigation and ease of acquisition in a graphical user interface
    Patent number: 10732813
    Abstract: The invention provides a method for dynamic user control over the layout of a graphical user interface. The method includes the steps of receiving a description of the way in which a control region in the interface is allocated to a plurality of virtual objects, without object overlap, receiving the position of a user point, reallocating a fraction of the control region from at least one object to a different object, based on the user point position, allocating a part of a display region in the interface to at least one of the objects, based on the current allocation of the control region to said object, but with control-display decoupling, and repeating the previous three steps fast enough that the user will perceive the changes as substantially continuous.
