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.

User control of the trade-off between rate of navigation and ease of acquisition in a graphical user interface

The invention provides a method for human-computer interaction (HCl) on a graphical user interface (GUI). The method includes the steps of displaying a plurality of objects positioned in relation to each other and in relation to the display window; determining user input; distorting at least one of the position relations according to a magnification function with a focal dip, where the focal position of the magnification function is controllable by the user input; and updating the distortion whenever the relevant user input changes.

Distortion viewing with improved focus targeting

The invention provides, a method for human-computer interaction on a graphical user interface (GUI). The method includes the steps of receiving first control coordinates for individualised control of a plurality of objects to be controlled&#x2014;by pointer coordinates; receiving display coordinates for the display' of the' plurality of objects, which relate to but are different from the first control coordinates; receiving pointer coordinates for individualised control of the objects based partly on the first control coordinates; using the display coordinates of at least one object to&#x2014;calculate new control coordinates associated with the same object, which new control coordinates generally correspond to the same objects display coordinates; and&#x2014;continuously repeating the above steps each time new pointer coordinates become available.

Dynamic information transfer from display to control

The invention relates to a method for human-computer interaction (HCI). The method includes: establishing an event set; establishing and referencing one or more events in the event set; establishing and referencing an event to represent the observer in the event set; establishing a representation manifold as an indefinite metric Riemann manifold; representing the events on the representation manifold in such a way that the logical relations between events are coordinate independent and geometrically encoded as causal relations; establishing an input manifold to represent user input; and establishing an output manifold that maps between the representation manifold and a physical output device. Further, based on user input, select any one or more steps from: manipulating the observer event, adjusting manifold metrics, changing mappings, adjusting mapping parameters, and applying mappings. The above steps are repeated when the user input changes.
