1. A portable communication device comprising:
- a housing;
a touch input device secured to the housing, the touch input device operatively coupled to a display and control circuitry, wherein the control circuitry is configured to;
display a keypad having a plurality of key input regions on the display, wherein at least one of the key input regions includes a plurality of symbols;
detect a key press in one of the key input regions, wherein the key input region where the key press was detected corresponds to a selected key input region;
displaying one or more of the plurality symbols associated with the selected key input region in one or more adjacent key input regions from the selected key input region, wherein each of the plurality of symbols are positioned in a separate key input region to allow direct selection of one of the plurality of symbols;
detecting a slide from the selected key input region to another key input region, wherein one of the plurality of symbols are displayed; and
detecting a key release in one of the adjacent key input regions corresponding to a selected symbol.

Abstract
A portable communication device (12) is equipped with a touch input device (16) that displays a plurality of key input regions, wherein at least one of the key input regions includes a plurality of symbols. A key press may be detected in one of the key input regions, which causes symbols associated with the selected key to be displayed in one or more adjacent key input regions. The user may slide an object (e.g., a finger, stylus, etc.) across from one key input region to another key input region to select a particular symbol. Generally, the symbol is selected by detecting a key release in the key region associate the selected symbol.

10. A method of entering symbols in an electronic device (12) having a touch input device, the method comprising:
-
displaying a plurality of key input regions on a display, wherein at least one of the key input regions includes a plurality of symbols; detecting a key press from an object in one of the key input regions of a touch input device, wherein the key input region where the key press was detected corresponds to a selected key input region and the selected key input region includes a plurality of symbols associated with the selected key input region; displaying one or more of the plurality of symbols associated with the selected key input region in one or more adjacent key input regions from the selected key input region, wherein each of the plurality of symbols are positioned in a separate key input region to allow direct selection of one of the plurality of symbols; and detecting a slide of the object from the selected key input region to another key input region, wherein one of the plurality of symbols are displayed; and detecting a key release in one of the adjacent key input regions corresponding to a selected symbol, wherein the key release is detected by detecting an absence of contact of the object on the touch input device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 19, 20)
