Patent ID: 8466934

Claim:
A user interface method for controlling a magnification event on a display screen of an electronic computing device to which an input device is coupled in response to an input event corresponding to a user, the user interface method comprising: determining a plurality of distances, the plurality of distances comprising: a user alterable initiation distance defining a first distance from the input device at which a pointing object is first detectable; a freezing distance defining a second distance of the pointing object from the input device at which a magnified event on the display screen can be frozen to define a frozen magnified event, the freezing distance different than the initiation distance; and an unfreezing distance defining a third distance of the pointing object from the input device at which the frozen magnified event can be unfrozen, the unfreezing distance different than the freezing distance, wherein at least one of the freezing distance and the unfreezing distance is user alterable; detecting an input event by the input device; determining at least one of a plurality of parameters of the input event by way of processing the input event by the electronic computing device, the plurality of parameters comprising a distance of a pointing object from the input device and a speed of displacement of the pointing object towards the input device; and automatically selecting a magnification factor, and at least one of a field of view size, and a size of a resultant magnified field of view for the magnification event, the magnification factor, and at least one of the field of view size, and the size of the resultant magnified field of view being determined in correlation to the at least one of the plurality of parameters of the input event.
