A wireless handheld device able to accept text input, including a display screen and a virtual keypad having a plurality of keys displayed on the display screen, wherein a first key of the virtual keypad is operable to display a first character associated with the first key in a text passage shown on the display screen in response to a first contact of a pointer with a first area on the display screen corresponding to the first key, the first contact including the pointer contacting and moving from the first area along a first direction while the pointer is in continual contact with the display screen, and wherein the first key of the virtual keypad is also operable to display a second character associated with the first key in the text passage shown on the display screen in response to a second contact of the pointer with the first area the display screen corresponding to the first key, the second contact including the pointer contacting and moving fro the first area along a second direction while the pointer is in continual contact with the display screen.

Description

technical field [0001] The present invention relates generally to wireless handheld devices for communication, and in particular to entering text into the aforementioned devices. Background technique [0002] A numeric keypad is commonly used on handheld electronic devices that cannot include a QWERTY keyboard due to size limitations. These devices may include, for example, mobile phones, media players, remote controls, and the like. The increase in the number of communication functions (such as instant messaging, short message transmission, etc.) included in the aforementioned devices has created a need for text entry using these numeric keypads. [0003] A common way to enter text using a numeric keypad is the "multi-tap" method, in which keys 2 to 9 are labeled with the letters A-Z in such a way that each key is labeled with 3 or 4 letters. In order to enter text, letters can be typed by repeatedly activating the corresponding key. For example, key 6 is labeled with th...
