Estimating the term…
A wireless user station (10), such as a cellular telephone, is provided with a touch sensitive input device, such as a touch-sensitive display (20) or a touchpad (23). A display device displays a plurality of symbols. A first location of a tactile input is detected and displayed symbols in the vicinity of the first location of the tactile input are magnified to occupy a larger display area. Subsequently, a second location of the tactile input is detected, thereby identifying a new position of the user's fingertip. After the second location on the touch sensitive screen remains constant, or after the user lifts the fingertip, the second location of the tactile input is reported and associated with the selected symbol.
A method for operating a wireless communicator having a display and a touch sensitive input device, said display displaying a plurality of symbols, comprising the steps of:
A user input device for a wireless communicator comprised of a touch sensitive display device, said display device displaying a plurality of symbols, said user input device comprising a controller bidirectionally coupled to said touch sensitive display device for detecting a first location of a user's tactile input on the touch sensitive display device and for magnifying one or more displayed symbols in the vicinity of the first location by emulating a presence of a lens element disposed over the touch sensitive display device so as to provide a localized magnification effect;
